Marsh Jr J, Vercnocke A, Rajendran K, Tao S, Anderson J, Ritman E, et al.
J Med Imaging (Bellingham)
. 2023 Feb;
10(1):016001.
PMID: 36778671
Purpose: The onset of atherosclerosis is preceded by changes in blood perfusion within the arterial wall due to localized proliferation of the vasa vasorum. The purpose of this study was...

J Med Imaging (Bellingham)
. 2020 Oct;
7(5):053501.
PMID: 33033732
Conventional stenosis quantification from single-energy computed tomography (SECT) images relies on segmentation of lumen boundaries, which suffers from partial volume averaging and calcium blooming effects. We present and evaluate a...

J Med Imaging (Bellingham)
. 2019 Mar;
5(4):043503.
PMID: 30840738
We assess the performance of a cadmium zinc telluride (CZT)-based Medipix3RX energy-resolving and photon-counting x-ray detector as a candidate for spectral microcomputed tomography (micro-CT) imaging. It features an array of...

Ritman E, Vercnocke A, Zamir M
Ann Biomed Eng
. 2019 Feb;
47(5):1281-1290.
PMID: 30734145
The branching architecture of arterial trees traversing the thickness of the left ventricular wall is studied to determine the way in which adequate blood supply is provided to myocardial tissue...

Sheikhzadeh M, Vercnocke A, Tao S, Rajendran K, Leng S, Ritman E, et al.
Acad Radiol
. 2018 Dec;
26(10):1410-1416.
PMID: 30528631
Rationale And Objectives: The purpose of this study was to determine the impact of effective detector-pixel-size and image voxel size on the accurate estimation of microvessel density (ratio of microvascular...

Rajendran K, Leng S, Jorgensen S, Anderson J, Halaweish A, Abdurakhimova D, et al.
J Med Imaging (Bellingham)
. 2017 Dec;
4(4):044006.
PMID: 29250564
Changes in arterial wall perfusion mark the onset of atherosclerosis. A characteristic change is the increased spatial density of vasa vasorum (VV), the microvessels in the arterial walls. Measuring this...

Rajendran K, Leng S, Jorgensen S, Abdurakhimova D, Ritman E, McCollough C
Proc SPIE Int Soc Opt Eng
. 2017 Apr;
10132.
PMID: 28413240
Changes in arterial wall perfusion are an indicator of early atherosclerosis. This is characterized by an increased spatial density of vasa vasorum (VV), the micro-vessels that supply oxygen and nutrients...

Jorgensen S, Korinek M, Vercnocke A, Anderson J, Halaweish A, Leng S, et al.
Proc SPIE Int Soc Opt Eng
. 2016 Nov;

PMID: 27807391
Early atherosclerosis changes perfusion of the arterial wall due to localized proliferation of the vasa vasorum. When contrast agent passes through the artery, some enters the vasa vasorum and increases...
