Journal ArticleDOI
Photon-counting CT for simultaneous imaging of multiple contrast agents in the abdomen: An in vivo study
Rolf Symons,Bernhard Krauss,Pooyan Sahbaee,Tyler E. Cork,Manu N. Lakshmanan,David A. Bluemke,Amir Pourmorteza +6 more
TL;DR: Photon‐counting spectral CT allowed simultaneous material decomposition of multiple contrast agents in vivo and tissue enhancement at multiple phases was observed in a single CT acquisition, potentially obviating the need for multiphase CT scans and thus reducing radiation dose.
Journal ArticleDOI
Dual-contrast agent photon-counting computed tomography of the heart: initial experience
Rolf Symons,Tyler E. Cork,Manu N. Lakshmanan,Robert Evers,Cynthia Davies-Venn,Kelly A. Rice,Marvin L. Thomas,Chia Ying Liu,Steffen Kappler,Stefan Ulzheimer,Veit Sandfort,David A. Bluemke,Amir Pourmorteza +12 more
TL;DR: Simultaneous multi-contrast agent cardiac imaging is feasible with photon-counting detector CT using occlusion-reperfusion canine model of myocardial infarction to simultaneously assess both first-pass and late enhancement of the myocardium.
Journal ArticleDOI
Comparison of dc and superconducting rf photoemission guns for high brightness high average current beam production
TL;DR: In this paper, a comparison of the two most prominent electron sources of high average current high brightness electron beams, dc and superconducting rf photoemission guns, is carried out using a large-scale multivariate genetic optimizer interfaced with space charge simulation codes.
Proceedings ArticleDOI
Coding and sampling for compressive x-ray diffraction tomography
Joel A. Greenberg,Kalyani Krishnamurthy,Manu N. Lakshmanan,Kenneth P. MacCabe,Scott D. Wolter,Scott D. Wolter,Anuj J. Kapadia,David J. Brady +7 more
TL;DR: In this article, a specific coded aperture x-ray coherent scatter imaging architecture is proposed to improve the sampling efficiency of xray tomography and increase the physical diversity of the xray phenomena measured.
Proceedings ArticleDOI
Optimization of a coded aperture coherent scatter spectral imaging system for medical imaging
TL;DR: A coherent-scatter imaging approach based on the use of coded apertures that enables fast, dose-efficient, high-resolution scatter imaging of biologically-relevant materials and is used to demonstrate automated material detection in biological tissue.
