Tomographic image reconstruction is a computationally demanding task, even more so
when advanced models are used to describe a more complete and accurate picture of the …

Computed tomography perfusion (CTP) is a functional imaging that allows for providing
capillary-level hemodynamics information of the desired tissue in clinics. In this paper, we …

Cone-beam computed tomography (CBCT) systems, with their flexibility, present a promising
avenue for direct point-of-care medical imaging, particularly in critical scenarios such as …

BACKGROUND AND PURPOSE: Perfusion imaging in the angiography suite may provide a
way to reduce time from stroke onset to endovascular revascularization of patients with large …

Background and Purpose—Multimodal imaging using cone beam C-arm computed
tomography (CT) may shorten the delay from ictus to revascularization for acute ischemic …

T noise in x-ray images is quantum noise. It follows a Poisson process that has a standard
deviation of N, where N is the number of photons that arrive at the detector pixel. us, the …

Background The success of embolization, a minimally invasive treatment of liver cancer,
could be evaluated in the operational room with cone‐beam CT by acquiring a dynamic …

Purpose The issue of perfusion imaging using a temporal decomposition model is to enable
the reconstruction of undersampled measurements acquired with a slowly rotating x‐ray …

Background CT perfusion imaging (CTP) is used in the diagnostic workup of acute ischemic
stroke (AIS). CTP may be performed within the angio suite using flat detector CT (FDCT) to …

Purpose The development and clinical employment of a computed tomography (CT)
imaging system benefit from a thorough understanding of the statistical properties of the …
