MO‐AB‐BRA‐02: A Novel Scatter Imaging Modality for Real‐Time Image Guidance During Lung SBRT
Authors: Redler G , Bernard D , Templeton A , Nair C Kumaran , Turian J , Chu J 
Published: June 2015

Purpose:A novel scatter imaging modality is developed and its feasibility for image‐guided radiation therapy (IGRT) during stereotactic body radiation therapy (SBRT) for lung cancer patients is assessed using analytic and Monte Carlo models as well as experimental testing.Methods:During treatment, incident radiation interacts and scatters from within the patient. The presented methodology forms an image of patient anatomy from the scattered radiation for real‐time localization of the treatment target. A radiographic flat panel‐based pinhole camera provides spatial information regarding the origin of detected scattered radiation. An analytical model is developed, which provides a mathematical formalism for describing the scatter imaging system. Experimental scatter images are acquired by irradiating an object using a Varian TrueBeam accelerator. The differentiation between tissue types is investigated by imaging simple objects of known compositions (water, lung, and cortical bone equivalent). A lung tumor phantom, simulating materials and geometry encountered during lung SBRT treatments, is fabricated and imaged to investigate image quality for various quantities of delivered radiation. Monte Carlo N‐Particle (MCNP) code is used for validation and testing by simulating scatter image formation using the experimental pinhole camera setup.Results:Analytical calculations, MCNP simulations, and experimental results when imaging the water, lung, and cortical bone equivalent objects show close agreement, thus validating the proposed models and demonstrating that scatter imaging differentiates these materials well. Lung tumor phantom images have sufficient contrast‐to‐noise ratio (CNR) to clearly distinguish tumor from surrounding lung tissue. CNR=4.1 and CNR=29.1 for 10MU and 5000MU images (equivalent to 0.5 and 250 second images), respectively.Conclusion:Lung SBRT provides favorable treatment outcomes, but depends on accurate target localization. A comprehensive approach, employing multiple simulation techniques and experiments, is taken to demonstrate the feasibility of a novel scatter imaging modality for the necessary real‐time image guidance.
MO‐AB‐BRA‐09: Temporally Realistic Manipulation a 4D Biomechanical Lung Phantom for Evaluation of Simultaneous Registration and Segmentation
Authors: Markel D , Levesque I R. , Larkin J , Leger P , El Naqa I 
Published: June 2015

Purpose:To produce multi‐modality compatible, realistic datasets for the joint evaluation of segmentation and registration with a reliable ground truth using a 4D biomechanical lung phantom. The further development of a computer controlled air flow system for recreation of real patient breathing patterns is incorporated for additional evaluation of motion prediction algorithms.Methods:A pair of preserved porcine lungs was pneumatically manipulated using an in‐house computer controlled respirator. The respirator consisted of a set of bellows actuated by a 186 W computer controlled industrial motor. Patient breathing traces were recorded using a respiratory bellows belt during CT simulation and input into a control program incorporating a proportional‐integral‐derivative (PID) feedback controller in LabVIEW. Mock tumors were created using dual compartment vacuum sealed sea sponges. 65% iohexol,a gadolinium‐based contrast agent and 18F‐FDG were used to produce contrast and thus determine a segmentation ground truth. The intensity distributions of the compartments were then digitally matched for the final dataset. A bifurcation tracking pipeline provided a registration ground truth using the bronchi of the lung. The lungs were scanned using a GE Discovery‐ST PET/CT scanner and a Phillips Panorama 0.23T MRI using a T1 weighted 3D fast field echo (FFE) protocol.Results:The standard deviation of the error between the patient breathing trace and the encoder feedback from the respirator was found to be ±4.2%. Bifurcation tracking error using CT (0.97×0.97×3.27 mm3 resolution) was found to be sub‐voxel up to 7.8 cm displacement for human lungs and less than 1.32 voxel widths in any axis up to 2.3 cm for the porcine lungs.Conclusion:An MRI/PET/CT compatible anatomically and temporally realistic swine lung phantom was developed for the evaluation of simultaneous registration and segmentation algorithms. With the addition of custom software and mock tumors, the entire package offers ground truths for benchmarking performance with high fidelity.
MO‐AB‐207‐03: ACR Update in Nuclear Medicine
Authors: Harkness B. 
Published: June 2015

A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up‐to‐date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements.Learning Objectives:

To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole‐body general purpose magnets, dedicated extremity systems well as breast MRI accreditation. Anticipated updates to the ACR MRI Quality Control Manual will also be reviewed.
To understand the requirements of the ACR CT accreditation program, including updates to the QC manual as well as updates through the FAQ process.
To understand the requirements of the ACR nuclear medicine accreditation program, and the role of the physicist in annual equipment surveys and the set up and supervision of the routine QC program.
To understand the current ACR MAP Accreditation requirement and present the concepts and structure of the forthcoming ACR Digital Mammography QC Manual and Program.

Authors: Richardson Susan 
Published: June 2015

The JACMP began publication in February, 2000 and is the world's oldest open‐access medical specialty journal. Today it publishes about 200 articles in six issues annually. The JACMP archive experiences about 400,000.pdf downloads annually and a typical JACMP.pdf article is downloaded about 600 or 700 times during the first year after publication. Anyone with web access can reach these articles, having wide distribution and benefiting as many patients as possible.Preparing a manuscript for publication in the JACMP (or any other journal) is a straightforward process. The primary purpose of a manuscript is to communicate knowledge and experience. A relatively fixed format has been developed to meet this goal; this format consists of an Abstract, Introduction, Methods and Materials, Results, and Conclusions. In addition to fitting your experience into that format, it is important to recognize your audience and direct your manuscript to that audience. Finally, it is important to write your manuscript in clear English, enlisting the aid of a copyeditor, if such an individual is available.Reviewing the articles submitted to JACMP is a rewarding yet difficult task. A reviewer must evaluate submitted articles critically, objectively, and express opinions diplomatically regarding work presented to the journal. A perspective from a JACMP section editor and experienced reviewer will describe the key points that progress a journal article to publication. As a reviewer, the difficulties experienced as a reviewer such as an incomplete or incorrect citations, incorrect formats, etc. will also be described.Learning Objectives:

Attendees will learn the history and philosophy behind the development of the Journal of Applied Clinical Medical Physics.
After attending this presentation, the participant will be able to prepare a well‐written manuscript suitable for publication in the JACMP or any other peer‐reviewed journal.
Attendees will learn what typical submission mistakes and difficulties are from the perspective of a section editor and experienced article reviewer.
MO‐B‐BRB‐01: Optimize Treatment Planning Process in Clinical Environment
Authors: Feng W. 
Published: June 2015

The radiotherapy treatment planning process has evolved over the years with innovations in treatment planning, treatment delivery and imaging systems. Treatment modality and simulation technologies are also rapidly improving and affecting the planning process. For example, Image‐guided‐radiation‐therapy has been widely adopted for patient setup, leading to margin reduction and isocenter repositioning after simulation. Stereotactic Body radiation therapy (SBRT) and Radiosurgery (SRS) have gradually become the standard of care for many treatment sites, which demand a higher throughput for the treatment plans even if the number of treatments per day remains the same. Finally, simulation, planning and treatment are traditionally sequential events. However, with emerging adaptive radiotherapy, they are becoming more tightly intertwined, leading to iterative processes. Enhanced efficiency of planning is therefore becoming more critical and poses serious challenge to the treatment planning process; Lean Six Sigma approaches are being utilized increasingly to balance the competing needs for speed and quality.In this symposium we will discuss the treatment planning process and illustrate effective techniques for managing workflow. Topics will include:

Planning techniques: (a) beam placement, (b) dose optimization, (c) plan evaluation (d) export to RVS.
Planning workflow: (a) import images, (b) Image fusion, (c) contouring, (d) plan approval (e) plan check (f) chart check, (g) sequential and iterative process
Influence of upstream and downstream operations: (a) simulation, (b) immobilization, (c) motion management, (d) QA, (e) IGRT, (f) Treatment delivery, (g) SBRT/SRS (h) adaptive planning
Reduction of delay between planning steps with Lean systems due to (a) communication, (b) limited resource, (b) contour, (c) plan approval, (d) treatment.
Optimizing planning processes: (a) contour validation (b) consistent planning protocol, (c) protocol/template sharing, (d) semi‐automatic plan evaluation, (e) quality checklist for error prevention, (f) iterative process, (g) balance of speed and quality
Learning Objectives:

Gain familiarity with the workflow of modern treatment planning process.
Understand the scope and challenges of managing modern treatment planning processes.
Gain familiarity with Lean Six Sigma approaches and their implementation in the treatment planning workflow.

MO‐D‐213‐01: Workflow Monitoring for a High Volume Radiation Oncology Center
Authors: Laub S , Dunn M , Galbreath G , Gans S , Pankuch M 
Published: June 2015

Purpose:Implement a center wide communication system that increases interdepartmental transparency and accountability while decreasing redundant work and treatment delays by actively monitoring treatment planning workflow.Methods:Intake Management System (IMS), a program developed by ProCure Treatment Centers Inc., is a multi‐function database that stores treatment planning process information. It was devised to work with the oncology information system (Mosaiq) to streamline interdepartmental workflow.Each step in the treatment planning process is visually represented and timelines for completion of individual tasks are established within the software. The currently active step of each patient's planning process is highlighted either red or green according to whether the initially allocated amount of time has passed for the given process. This information is displayed as a Treatment Planning Process Monitor (TPPM), which is shown on screens in the relevant departments throughout the center. This display also includes the individuals who are responsible for each task.IMS is driven by Mosaiq's quality checklist (QCL) functionality. Each step in the workflow is initiated by a Mosaiq user sending the responsible party a QCL assignment. IMS is connected to Mosaiq and the sending or completing of a QCL updates the associated field in the TPPM to the appropriate status.Results:Approximately one patient a week is identified during the workflow process as needing to have his/her treatment start date modified or resources re‐allocated to address the most urgent cases. Being able to identify a realistic timeline for planning each patient and having multiple departments communicate their limitations and time constraints allows for quality plans to be developed and implemented without overburdening any one department.Conclusion:Monitoring the progression of the treatment planning process has increased transparency between departments, which enables efficient communication. Having built‐in timelines allows easy prioritization of tasks and resources and facilitates effective time management.
