Authors: Guessasma S. , Montavon G. , Coddet C. , Mancini C. , Berndt C.C. 
Published: October 2022

Abstract
The chemical and physical properties of thermally sprayed coatings depend in part on surface characteristics, such as texture and roughness, that can be difficult to quantify. This paper demonstrates the use of fractal analysis for quantifying surface roughness based on images obtained from cross-sectioned samples. An isolated profile of an Al2O3-TiO2 coating on an aluminum substrate is used as the test case. The first part of the paper covers the basic concept and the procedures used. The second part presents practical examples and precautions that must be observed to obtain accurate and reproducible results. Paper includes a German-language abstract.

Method for Calculating the Radius of an Electromagnetic Availability Zone based on a Surface Wave Source with a Given Spectrum Density of an Isotropically Emitted Signal
Authors: Popov O. , Tumashov A. , Borisov G. , Korovin K. 
Published: October 2022

Thematic justification. When planning HF radio communication using surface waves, it is necessary to determine the signal-to-noise ratio at the inputs of each radio link receiver. Given a sufficiently high ratio, a conclusion can be drawn concerning the effective functionality of the analyzed radio link in a radio communication system. The planning process will be significantly simplified if the radius of the electromagnetic availability zone (REAZ) can be defined for surface waves at each radio station. Thus, the task of developing a methodology for engineering calculation of REAZ is relevant and practically important. Goal. To develop an estimating technique for engineering calculations of a REAZ based on a surface wave source with a given isotropically emitted signal spectrum density. Results. A technique for calculation of the radius of the electromagnetic accessibility zone was developed. A general approach for determining the limiting length of radio links of surface waves is proposed, based on the introduced "technical factor of a radio link" concept. Practical implications. Nomograms for determining the radius of an electromagnetic accessibility zone were constructed. The dependence of the maximum temperature of external noise on frequency in the HF range can be approximated using an analytical expression. The developed frequency dependence of the temperature coefficient of the input of an ShT4N81 antenna is presented in a graphical form. The feasibility of using the proposed technique for solving practical problems is demonstrated on the example of calculating the radius of the electromagnetic accessibility zone of a TTR-2101M radio station for a monopulse direction finder with a ring antenna array consisting of eight elements of the ShT4N81 type.
Radiologic Evaluation of the Anterior and Posterior Ethmoidal Foramen and Optic Canal by Paranasal Sinus Computed Tomography Scan among Adult Filipinos
Authors: Palacios Maria Katerina , Amable Jay Pee , Capio Kea 
Published: October 2022

ABSTRACT

Objective: To measure the average distances from anterior lacrimal crest (ALC) to anterior ethmoidal foramen (AEF), anterior ethmoidal foramen to posterior ethmoidal foramen (PEF) and posterior ethmoidal foramen to optic canal (OC) using plain paranasal sinus (PNS) computed tomography (CT) scans of adults in a tertiary private hospital in the Philippines.
Methods:
Design: Retrospective review of plain PNS CT scans
Setting: Tertiary Private Teaching Hospital
Participants: One hundred four (104) plain PNS CT scans from January 2018 to December 2020 were considered for inclusion.
Results: Of the 104 PNS CT scans, 35 were excluded - seven for age less than eighteen, six for undistinguishable PEF and twenty-two for chronic rhinosinusitis. The remaining 69 PNS CT scans demonstrated identifiable structures, with overall average distances from ALC to AEF of 23.71 ± 2.43 mm, AEF to PEF of 10.87 ± 2.39 mm and PEF to OC of 7.39 ± 2.28 mm.
Conclusion: Our study suggests average distances for localization of vital structures such as the anterior ethmoidal artery, posterior ethmoidal artery and optic nerve among Filipinos. Because of considerable variation between and within sexes, individual measurements should still be obtained for each patient in performing endonasal, skull base and orbital surgery.
Automated Midline Estimation for Symmetry Analysis of Cerebral Hemispheres in FLAIR MRI
Authors: Gibicar Adam , Moody Alan R. , Khademi April 
Published: October 2022

<p>To perform brain asymmetry studies in large neuroimaging archives, reliable and automatic detection of the interhemispheric fissure (IF) is needed to first extract the cerebral hemispheres. The detection of the IF is often referred to as mid-sagittal plane estimation, as this plane separates the two cerebral hemispheres. However, traditional planar estimation techniques fail when the IF presents a curvature caused by existing pathology or a natural phenomenon known as brain torque. As a result, midline estimates can be inaccurate. In this study, a fully unsupervised midline estimation technique is proposed that is comprised of three main stages: head angle correction, control point estimation and midline generation. The control points are estimated using a combination of intensity, texture, gradient, and symmetry-based features. As shown, the proposed method automatically adapts to IF curvature, is applied on a slice-to-slice basis for more accurate results and also provides accurate delineation of the midline in the septum pellucidum, which is a source of failure for traditional approaches. The method is compared to two state-of-the-art methods for midline estimation and is validated using 75 imaging volumes (similar to 3,000 imaging slices) acquired from 38 centers of subjects with dementia and vascular disease. The proposed method yields the lowest average error across all metrics: Hausdorff distance (HD) was 0.32 +/- 0.23, mean absolute difference (MAD) was 1.10 +/- 0.38 mm and volume difference was 7.52 +/- 5.40 and 5.35 +/- 3.97 ml, for left and right hemispheres, respectively. Using the proposed method, the midline was extracted for 5,360 volumes (similar to 275K images) from 83 centers worldwide, acquired by GE, Siemens and Philips scanners. An asymmetry index was proposed that automatically detected outlier segmentations (which were <1% of the total dataset). Using the extracted hemispheres, hemispheric asymmetry texture biomarkers of the normal-appearing brain matter (NABM) were analyzed in a dementia cohort, and significant differences in biomarker means were found across SCI and MCI and SCI and AD. </p>

<p>Major hardware/software changes to MRI platforms, either planned or unplanned, will almost invariably occur in longitudinal studies. Our objective was to assess the resulting variability on relevant imaging measurements in such context, specifically for three Siemens Healthcare Magnetom Trio upgrades to the Prisma(fit) platform. We report data acquired on three healthy volunteers scanned before and after three different platform upgrades. We assessed differences in image signal [contrast-to-noise ratio (CNR)] on T1-weighted images (T1w) and fluid-attenuated inversion recovery images (FLAIR); brain morphometry on T1w image; and small vessel disease (white matter hyperintensities; WMH) on FLAIR image. Prisma(fit) upgrade resulted in higher (30%) and more variable neocortical CNR and larger brain volume and thickness mainly in frontal areas. A significant relationship was observed between neocortical CNR and neocortical volume. For FLAIR images, no significant CNR difference was observed, but WMH volumes were significantly smaller (-68%) after Prisma(fit) upgrade, when compared to results on the Magnetom Trio. Together, these results indicate that Prisma(fit) upgrade significantly influenced image signal, brain morphometry measures and small vessel diseases measures and that these effects need to be taken into account when analyzing results from any longitudinal study undergoing similar changes. </p>
