New Interface Metaphors for Complex Information Space Visualization: an ECG Monitor Object Prototype
Authors: Kaufman Stan  , Poupyrev Ivan  , Miller Edward  , Billinghurst Mark  , Oppenheimer Peter  , Weghorst Suzanne
Published: February 2025

Wearable augmented reality medical (WARM) interfaces could provide ubiquitous point-of-care decision support and enhance the quality and efficiency of clinicians' efforts. Creation of such systems involves the design and evaluation of new information displays that leverage the representational and presentational capabilities of three-dimensional AR environments. We describe our first efforts in this process: the implementation of interface objects for display of real-time electrocardiographic monitoring information and an evaluation methodology using a simulated clinical environment. Our pilot data confirm the utility of presentation modes that place simultaneous information tasks in close proximity, and highlight issues encountered in designing new representations of medical information.
Virtual Cancer Image Data Warehouse
Authors: Oyama Hiroshi  , Wakao Fumihiko  , Mishina Tsuyoshi  , Yimeng Lu  , Honjo Akira
Published: February 2025

We previously developed a system with which we have created more than 100 virtual cancer images from CT or MR data of individual patients with cancer (Cancer Edutainment Virtual Reality Theater: CEVRT). These images can be used to help explain procedures, findings, etc. to the patient, to obtain informed consent, to simulate surgery, and to estimate cancer invasion to surrounding organs. We recently developed a web-based object-oriented database both to access these cancer images and to register medical images at international research sites via the Internet. In this report, we introduce an international medical VR data warehouse created using an object-oriented database.
A Flexible and Extensible Object-Oriented 3D Architecture: Application in the Development of Virtual Anatomy Lessons
Authors: Hoffman Helene  , Murray Margaret  , Danks Mark  , Prayaga Ram  , Irwin Ann  , Vu Dzung
Published: February 2025

“Anatomic VisualizeR©” represents the first application to be developed using a 3D architectural framework created at the University of California, San Diego, School of Medicine. This application combines 3D anatomic models (based on the Visible Human™ dataset) with supporting 2D media (e.g., diagnostic imagery, surgical videos, etc.) to establish a comprehensive learning environment for anatomy. “Guided lessons” are being created to address complex curricular and learning objectives. Faculty expertise is represented in these preconfigured lessons, in part through the specification of appropriate content and the incorporation of activities to enhance visualization. These lessons are an intellectual framework which ensures that clinically-relevant issues and ancillary learning opportunities are available. The curricular exercises are non-sequential and can be interrupted at any time; users are encouraged to freely explore the environment. At the core of Anatomic VisualizeR©'s object-oriented architecture is the ability to identify, access, view, and manipulate heterogeneous content. The capacity to query a database gateway to retrieve specified resources has been built into the application. Encapsulation of individual elements to form 3D display objects (“blocks”) enables Anatomic VisualizeR© to efficiently manage 3D models, 2D images, text, sound, and video. The “block” paradigm also allows Anatomic VisualizeR© to associate contextually appropriate display characteristics and behaviors with the various content elements. For example, the anatomic model block provides the capability to “link” and “unlink” the anatomic models and to alter their transparencies. The anatomic models can be displayed concurrently with other blocks to facilitate structural comparisons. Anatomic VisualizeR© marks a major milestone in our developmental efforts. While lessons and database content are still not complete, we are confident that it will become the first tangible realization of our vision.
Blind Persons Navigate in Virtual Reality (VR); Hearing and Feeling Communicates “Reality”
Authors: Max Mayer L.  , Gonzalez Jesse R.
Published: February 2025

Can Virtual Reality (VR) developments in audio navigation for blind persons support therapies for all? Working with Crystal River Engineering we are developing navigable Virtual Reality worlds for blind users, using spatialized audio [1], [2]. All persons, however, use specialized channels, such as: visual, aural, and kinetic learning senses. Predominantly visual VR worlds and health informatics models from World Wide Webs, may be downloaded, tailored, augmented, and delivered to each of these learning senses using VR. We are also testing a proof of concept system with Boston Dynamics which downloads 3-dimensional, satellite-derived map models from the World Wide Web, and makes them navigable by “feeling” the terrain using haptic (tactual or force feedback to your hand) robotic interfaces. Ultimately, these multi-sensory VR access methods: sight, localization by audio, and “feeling” of data sets could open up the World Wide Web to individuals with sight impairments. This could also, however, benefit government, businesses, universities, and (elementary) education. It could contribute more powerful communications, education, and medical simulation applications on the World Wide Web. This work is part of government technology transfer to telemedicine, (elementary) education, disabilities access to the Web, and new Internet access and productivity efforts under Vice President Gore's National Performance Review.
The Props-Based Interface for Neurosurgical Visualization
Authors: Hinckley Ken  , Pausch Randy  , Downs J. Hunter  , Proffitt Dennis  , Kassell Neal F.
Published: February 2025

We describe a three-dimensional human-computer interface for neurosurgical visualization. The interface is based on the two-handed physical manipulation of hand-held tools, or “props”, in free space. These user interface “props” facilitate transfer of the user's skills for manipulating tools with two hands to the operation of a user interface for visualizing 3D medical images, without need for training. The interface allows neurosurgeons to explore a 3D MRI scan of a patient's brain during presurgical planning. From the surgeon's perspective, the interface is analogous to holding a miniature head in one hand which can be “sliced open” or “pointed to” using a cross-sectioning plane or a stylus tool, respectively, held in the other hand. Cross-sectioning a 3D volume, for example, simply requires the surgeon to hold a plastic plate (held in the preferred hand) up to the miniature head (held in the nonpreferred hand) to demonstrate the desired crosssection.
Patient Specific Color Texture Mapping of CT-based Anatomical Surface Models Utilizing Cryosection Data
Authors: Knapp Darren  , Kerr John P.  , Sellberg Michael
Published: February 2025

In traditional medical imaging modalities, color and texture information can add considerable information for diagnostics. Presently, multimodal images of a patient are unregistered and referenced independent of each other, or registered and fused into a single hybrid volume. Doctors and other medical professionals need to be able to visualize and interrogate, on a per-patient basis, a wide variety of 2D and 3D data representations that can be created from non-invasive imaging modalities, such as MRI and CT. In addition, any colorization that may be applied to the image data is strictly based on tissue density, radiation emission, or magnetic signature, and not on any physiological foundation. In order for “true-to-life” color information to be incorporated with non-invasive imaging techniques, and for it to be of consistent quality across the entire body, a single whole-body cryosection specimen with associated medical image data is needed. The National Library of Medicine's Visible Human Project offers just such a specimen. Using the full-body medical image data along with the cryosection images of the Visible Human subject, a set of color lookup tables for all visually well defined structures and organs can be created. As a result, patient-specific colorization based on real tissue color and characteristics can be incorporated into traditional intensity-based imaging modalities.
Diaphyseal Bone Growth and Adaptation: Models and Data
Authors: van der Meulen Marjolein C.H.
Published: February 2025

The cross-sectional growth and development of the long bone diaphysis is strongly influenced by in vivo mechanical loading. An analytical approach was developed to model these mechanobiologic influences. First, human growth under normal loading conditions was modeled. Our model predictions were validated by comparison to human data obtained during adolescence. Next, skeletal adaptation during growth under altered loading conditions was examined using an animal model. Rat hindlimb suspension experiments were performed and femoral adaptation to reduced loading during growth was measured and compared to normal controls. Then our model predictions of adaptation during growth were compared directly to our experimental data.
A Model Curriculum for Health Care Informatics and the Development of Learning Materials for Dutch higher Professional Education
Authors: Hoekstra Sylvia  , Aarts Jos
Published: February 2025

This paper describes briefly a model curriculum for health care informatics and the development of learning materials based on that curriculum for Dutch higher professional education. The following professions are involved: nursing, physiotherapy, occupational therapy, speech therapy and dietetics. Based on profiles of these professions which describe their skills in the year 2000, the curriculum is developed and emphasises the needs of using structured data and information to perform tasks in health care delivery and management, for which modern information technology is a necessary tool. The model curriculum is divided into sixteen modules which cover the broad range of medical informatics. Most of these modules are suitable for all professions but some are focusing on the contents of a specific profession. The learning materials and their characteristics are described. The content of one module is described as an example.

A Hypertext Information System for Standard Operating Procedures in Haematological Intensive Care
Authors: Horsch A.  , Sokol R.  , Heneka D.  , Lasic G.
Published: February 2025

In times of cost reduction efforts the role of standard operating procedures for both medical and nursing procedures gets increasing importance. Such standards are necessary if the quality of patient care shall not suffer but even improve. While some sophisticated approaches are coming up with generation of clinical processes from formal protocol models in connection with documentation systems the clinical practice actually looks quite different: Paper-based “operating standards” are used in day-to-day work, if any. In this paper a simple and powerful WWW-based hypertext information system for easy provision and maintenance of nursing standards is presented.

The Necessity of Urologie Ultrasound Images Processing
Authors: Crivianu-Gaita Daniela  , Gaspar A.  , Muntean G.  , Miclea F.L.  , Holban S.T.
Published: February 2025

The purpose of the paper is to present a software system for the handling and management of urologic ultrasound images. In particular, the system was used to detect men’s prostate in ultrasound images and than to obtain a 3D model for the detected object and to calculate its volume. The software system can be used in hospitals which do not have either CAT scanners or NMR/MRI equipment (the majority of Romanian hospitals). It provides these hospitals with a tool enabling a more accurate diagnosis, which in turn improves the efficiency of the hospital, saves money, and has a profound psychological benefit on the well-being of the patient.
The Performance and Reliability of Wavelet Denoising for Doppler Ultrasound Fetal Heart Rate Signal Preprocessing
Authors: Papadimitriou S.  , Papadopoulos V.  , Gatzounas D.  , Tzigounis V.  , Bezerianos A.
Published: February 2025

The present paper deals with the performance and the reliability of a Wavelet Denoising method for Doppler ultrasound Fetal Heart Rate (FHR) recordings. It displays strong evidence that the denoising process extracts the actual noise components. The analysis is approached with three methods. First, the power spectrum of the denoised FHR displays more clearly an l/fascaling law, i.e. the characteristic of fractal time series. Second, the rescaled scale analysis technique reveals a Hurst exponent at the range of 0.7-0.8 that corresponds to a long memory persistent process. Moreover, the variance of the Hurst exponent across time scales is smaller at the denoised signal. Third, a chaotic attractor reconstructed with the embedding dimension technique becomes evident at the denoised signals, while it is completely obscured at the unfiltered ones.

Published: February 2025

The problem of defining a quality model to be used in the evaluation of the software components of a Health Care System (HCS) is addressed. The model, based on the ISO/IEC 9126 standard, has been interpreted to fit the requirements of some classes of applications representative of Health Care Systems, on the basis of the experience gained both in the field of medical Informatics and assessment of software products. The values resulting from weighing the quality characteristics according to their criticality outline a set of quality profiles that can be used both for evaluation and certification.
Intranet Technology in Hospital Information Systems
Authors: Cimino James J.
Published: February 2025

The clinical information system architecture at the Columbia-Presbyterian Medical Center in New York is being incorporated into an intranet using Internet and World Wide Web protocols. The result is an Enterprise-Wide Web which provides more flexibility for access to specific patient information and general medical knowledge. Critical aspects of the architecture include a central data repository and a vocabulary server. The new architecture provides ways of displaying patient information in summary, graphical, and multimedia forms. Using customized links called Infobuttons, we provide access to on-line information resources available on the World Wide Web. Our experience to date has raised a number of interesting issues about the use of this technology for health care systems.

The Learning Collaboratory: A Knowledge-Building Environment for Nursing Education
Authors: Skiba D.J.
Published: February 2025

As we approach the 21st century, higher education must face many challenges. One challenge is the transformation of education from a teacher-focused to a learner-centered model. To accomplish this learner-centered model, several learning strategies are proposed to create socially relevant, distributed, and modular courses. This project creates a Learning Collaboratory whose overall goals are to build a knowledge-building environment for students to learn about nursing and to serve as a future global model for nursing education and interdisciplinary coursework.. To begin this transformation, the research sequence for the graduate program was selected as the first pilot. This paper describes the analysis, redesign and implementation of the existing research courses during the 1996-1997 academic year.
Important Considerations about Nursing Intelligence and Information Systems
Authors: Ballard E.C.
Published: February 2025

This discussion focuses on the importance of nursing intelligence to the organisation, and the nurses' role in gathering and utilising such intelligence. Deliberations with professional colleagues suggest that intelligence can only be utilised fully when the information systems are developed in such a way as to meet the needs of the people who manage and provide nursing care at the consumer level; that is, the activity of nursing itself. If accommodation is made for the recycling of nursing intelligence, there would be a support and furtherance of ‘professional’ intelligence. Two main issues emerge:

Authors: Eurlings F.  , van Asten A.  , Cozijn H.  , Klaassen K.  , Stokman R.  , van Valkenburg R.  , van Gennip E.
Published: February 2025

Two studies of the effects of components of the integrated Nursing Information System VISION, involving five Dutch hospitals, were concluded in 1996. This paper summarises these studies and their results. The studies assessed effects on workload, quality of co-ordination, job satisfaction, patient satisfaction and quality of information supply. In both studies a quasi-experimental approach was followed. The results show significant positive effects with respect to quality of co-ordination, nurses job satisfaction and patient satisfaction. Workload measurements revealed a shift in the nurses' activities, but no change in the amount of time spent on patient care. On the basis of the positive results, 4 of the 5 hospitals have decided to extend the use of the system.
Improving the Quality of Life for Older People by Design
Authors: Coleman Roger
Published: February 2025

In this paper it is argued that design has an important role to play in developing age-friendly products and services, and in particular in ensuring that mainstream products and new technologies respond to and meet the needs of older people. There are already many examples of good and appropriate design, and the philosophies, methodologies and strategies that are needed are largely in place. In order to put these concepts into practice on a significant scale the value of design as applied research should be recognised, and designers brought into research and development programmes and projects from the very beginning. The concept of ‘critical users’ is introduced and it is argued that working with older users can act as a spur to innovation and improvements in products and services. Technology should serve people, and the needs of older people will best be served by regarding them as consumers and including them in the research and development process.

Published: February 2025

Public trust and patient commitment are important factors in the successful development of an information highway in the health care sector. In order to foster trust and commitment for these systems, the present project consists in the development and implementation of graphic user interface solutions which allow patients access to their personal health information and their consent before certain personal information (are disclosed to) authorized professionals. As for the technological means adopted by this project, we believe microchip cards-what we call our Patient Smart Card and our Professional Smart Card-to be the ideal media to attain these functions. The project will be conducted at the Unité de Médecine Familiale de l'Enfant-Jésus beginning in March 1998 and will involve 20 physicians and 300 patients.
Security for Collaborative Telemedicine
Authors: Raman R.S.  , Kannan S.  , Baker D.V.  , Reddy R.
Published: February 2025

The practice of telemedicine requires healthcare providers to have ready access to relevant patient health information. Some of this information may need to be rapidly retrieved from remote healthcare facilities. Managing access to healthcare information is a growing concern to healthcare organizations as the means to retrieve, intercept and manipulate information rapidly become easier. Technologies that facilitate access to information enable authorized and unauthorized uses of healthcare information whether it be from a computer in the adjoining room or a continent away. In the USA, legislative measures for the protection of healthcare information place significant responsibilities on healthcare organizations to ensure that their healthcare systems and information technology practices adequately protect the privacy of the healthcare information in their charge. Smart cards for health professionals and patients used in conjunction with a public key infrastructure and crypto-aware applications and services offer a way to conduct secure telemedicine transactions. The authors, who are developing secure telemedicine applications, outline their approach to enable healthcare organizations engage in collaborative healthcare activities.
Economics of Chip Cards in Health Care: Insurance Cards and Electronic Prescriptions
Authors: Geiss E.
Published: February 2025

Insurance cards are considered to be the first step towards a more ambitious application of chip cards in the area of health care. In Germany, the nation-wide implementation of health insurance cards is gaining importance as part of a medium term cost reduction strategy. Increased usage of this technology is not a question of feasibility but of economic efficiency. The federal associations of doctors, pharmacists, and health insurance funds are preparing for the use of electronic prescriptions instead of conventional paper forms. This marks the next phase of their common initiative to cut costs in the complex data flow within the health care system.
A NEW PROJECT FOR REHABILITATION AND PSYCHOMOTOR DISEASE ANALYSIS WITH VIRTUAL REALITY SUPPORT
Authors: Rovetta Alberto  , Lorini Flavio  , Canina Marita
Published: February 2025

This paper deals with the project DD1-97, developed inside European Project VREPAR, for the application of a new equipment for psychomotor disease analysis and rehabilitation. The small equipment presents a glove for one finger, with sensors, which detect the movement of the phalanges and the force of the finger tip on a button. Electromyographs are measuring the nervous signals from flexion and extension muscles of the finger. In a portable computer a program examines the signals and elaborates them. The commands for the patient are of 4 kinds: -dynamic motion of the finger; - motion with vision of the finger; - motion without vision of the finger; - control by the images from virtual reality which reproduces the “virtual finger”. The results with healthy persons show a distribution in the foreseen range; with disabled person (with Parkinson's disease) show that virtual reality may support rehabilitation for neuromotor problems. The equipment is designed with reference to the most modern ergonomic concepts.
MODERN COSMOLOGY AND THE ORIGIN OF OUR THREE DIMENSIONALITY
Authors: Woodbury Sr. Michael A.  , Woodbury Margarita F.
Published: February 2025

We are three dimensional egocentric beings existing within a specific space/time continuum and dimensionality which we assume wrongly is the same for all times and places throughout the entire universe. Physicists name Omnipoint the origin of the universe at Dimension zero, which exploded as a Big Bang of energy proceeding at enormous speed along one dimension which eventually curled up into matter: particles, atoms, molecules and Galaxies which exist in two dimensional space. Finally from matter spread throughout the cosmos evolved life generating eventually the DNA molecules which control the construction of brains complex enough to construct our three dimensional Body Representation from which is extrapolated what we perceive as a 3-D universe. The whole interconnected structures which conjure up our three dimensionality are as fragile as Humpty Dumpty, capable of breaking apart with terrifying effects for the individual patient during a psychotic panic, revealing our three dimensionality to be but “maya””, an illusion, which we psychiatrists work at putting back together.
A PATIENT-CENTRIC APPROACH TO TELEMEDICINE DATABASE DEVELOPMENT
Authors: Peifer John  , Hopper Andrew  , Sudduth Barry
Published: February 2025

Computer and telecommunications technologies have unleashed a wide range of powerful tools for gathering, storing, and distributing patient information. Computerized records enable healthcare providers to rapidly access patient data and to closely monitor patients from a distance. These significant advantages can be further extended by using the technology to more fully involve patients in their own healthcare management. A patient-centric approach to telemedicine means that the patient takes on additional responsibility and control, and the benefits from increased patient involvement will translate into improved compliance, reduced litigation, lower costs, and better outcomes. Furthermore, there are often important ethical questions that are best decided by the informed patient. Patients have a right to know what information is being gathered and who will be authorized to access that information. Current health information systems do not adequately address these issues, and telemedicine applications -- particularly home based telemedicine -- is forcing everyone to take a closer look at patients’ roles in their own healthcare. In this presentation, a patient-centric home telemedicine database is described, the limitations are discussed, and future directions are proposed.

Health Care Workers and Their Needs: The Forgotten Shadow of AIM Research
Authors: Lillehaug Svein-Ivar  , Lajoie Susanne
Published: February 2025

The field of AI in Medicine (AIM) seems to have accepted that decision support is, and will be, needed within most medical domains. As society calls for cost-effectiveness, and human expertise or expert guidance are not always available, decision support systems (DSSs) are proposed as the solutions. These solutions, however, do not necessarily correspond with the basic needs of their targeted users. We will show this through a review of the literature related to health care workers and the various factors that have an influence on their performances. Furthermore, we will use these empirical findings to argue that the AIM community must go beyond its decision support philosophy, whereby the gaps in human expertise are filled in by the computer. In the future, joint emphasis must be placed on decision support and the promotion towards independent and self-sufficient problem solving. In order to implement this paradigm change, the AIM community will have to incorporate findings from the research discipline of AI in Education.
Components of the Optimal Ambulatory Care Computing Environment
Authors: Teich Jonathan M.  , Sittig Dean F.  , Kuperman Gilad J.  , Chueh Henry C.  , Zielstorff Rita D.  , Glaser John P.
Published: February 2025

We present here a framework of core components of an ambulatory care computing environment, based on clinical and functional needs and workflow scenarios. We have established this framework through the use of two study devices: a vision of the clinical office of the future, and a survey of possible computer applications, both designed to help clinicians and practice directors communicate their information needs to systems designers. Clinicians prioritize applications based on strategic and practice goals: support for clinical users' workflow, improved quality of care, reduced cost of care, and the ability to measure performance and status. By reorganizing the needed functionality from a clinical viewpoint into a technical viewpoint, we are able to identify core information components for systems design.
System Approach for A Multicenter, Multilingual International Telemedicine Conference

Published: February 2025

Chinese Telemed 96, a three way international telemedicine conference was successfully held in November 1996. Over 1,000 physicians, allied health professionals and medical students participated in this conference in Beijing, Hong Kong and London. This program demonstrated that the quality of telecommunication technology was suitable for the Chinese University of Hong Kong, Faculty of Medicine to use it in facilitating medical consultations and sharing expertise among widely dispersed colleagues. The consensus of Hong Kong participants was that the audiovideo and telecommunication technology used in this conference were adequate. In order to improve overall quality, however, a better co-ordination of the technical support across sites is required Other felt that the conference suffers from the shortage of highly trained technical staff required to support the communication system. However, following the total evaluation of this conference, it is concluded that while technical support, site and location are important factors in a good telemedicine conference, a well run telemedicine conference is more dependent on a sound planning process and its execution.

Authors: François Martial  , Joubert Michel  , Fieschi Dominique  , Fieschi Marius
Published: February 2025

Several databases on drugs have been developed worldwide for drug information functions whose sources are now electronically available. Our objective was to implement one of them in our University hospitals information system. Theriaque is a database which contains information on all the drugs available in France. Before its implementation we modeled its content (chemical classes, active components, excipients, indications, contra-indications, side effects, and so on) following an objectoriented method. From this model we designed dynamic HTML pages according to the Microsoft’s Internet Database Connector (IDC) technics. This allowed a fast implementation and does not imply to port a client application on the thousands of workstations over the network of the University hospitals. This interface provides end-users with an easy-to-use and natural way to access information related to drugs in an Intranet environment.

Asan Medical Center (AMC) completed a major migration process of the hospital information system from a mainframe towards an open Unix client server architecture from August of 1993 to August of 1996. Along with the east wing extension of AMC, the number of inpatient beds is greatly increased from 1,000 to 2,200 and information transaction increased from 300,000 to 700,000. A gradual departmental migration strategy with local area network connection and data conversion between the two systems were applied The successful migration process towards a client server architecture provided improved user interface, enhanced flexibility and productivity of the system, better integration with diverse medical devices and improved networking flexibility.

Published: February 2025

DIOGENE 2 is a full-scale distributed / open hospital information system that by June 1995 had already achieved its migration from a former mainframe system. Thanks to that architecture there is an obvious need for a common «glue» devoted to tightening up scattered applications into a middleware-based network of interoperability. After this the design of open / distributed Electronic Patient Records (EPRs) became feasible. A brief historical sketch of DIOGENE is presented from its initial to its present phase. A working prototype of these distributed EPRs is discussed showing current achievements during its first stage of production in the clinics of the University Hospitals of Geneva. On-going expansion to other public hospitals, as well as to general practioners (GPs) in the Geneva area, are partly described.

The evolution of the paper-based to Computer-based Patient Records (CPR) or Electronic Patient Records (EPR) changes the way in which we have to perceive and deal with privacy and security issues. The education and awareness of the users and public of the selfsame issues hold a very important role. A survey was conducted by the Laboratory of Health Informatics of the University of Athens concerning the awareness of future health care professionals. The results are discussed further down and an attempt to define profiles of training courses on security is made.

VIRTUAL REALITY IN NEUROSCIENCE: A SURVEY
Authors: Riva Giuseppe
Published: February 2025

Some research projects have begun to test the possibility of using Virtual Environments (VEs) for research in neuroscience, neurosurgery and for the study and rehabilitation of human cognitive and functional activities. In fact, VEs let users navigate and interact with computer-generated 3-D environments in real time, allowing for the control of complex stimulus presentations. VEs enable the neuroscientist to present a wide variety of controlled Stimuli and to measure and monitor a wide variety of responses made by the user.

Published: February 2025

A new method which allows the intraoperative 3D reconstruction of the entire spine from biplanar radiographs was developed in order to evaluate the 3D correction of scoliotic deformities during the surgical procedure. This new reconstruction technique uses a calibration object built from a 21 cm × 27 cm aluminium sheet, folded in three perpendicular faces, with 15 embedded markers. Computer simulations were performed to evaluate the optimal size and position of the calibration object to obtain an accurate 3D reconstruction for clinical applications. The validation of the proposed method on real images of a physical object showed that the new technique gives better results than the DLT technique in a real surgical environment.

The goal of this study is to compare the 3-D correction obtained with a derotation maneuver (C-D) versus a translation maneuver (Colorado) of the first instrumentation rod during scoliosis surgery in order to determine if one technique or system provides better 3-D correction of idiopathic scoliosis. Seventy adolescents undergoing corrective surgery were evaluated intra-operatively using a 3-D magnetic digitizer while 67 were evaluated by comparing pre- and postoperative standing radiographic 3-D reconstructions of their spine. Adequate and similar corrections were obtained in the C-D and Colorado groups. A significant better correction of thoracic curves in the frontal plane was observed by the pre-post standing comparison in the Colorado group, a finding which may be explained by the greater proportion of pedicle screws used in that group.
