Noise and dose reduction in CT brain perfusion acquisition by projecting time attenuation curves onto lower dimensional spaces
Vojtěch Kulvait, Philip Hoelter, Arnd Doerfler +1
CT perfusion imaging (CTP) plays an important role in decision making for the treatment of acute ischemic stroke with large vessel occlusion. Since the CT perfusion scan time is ap…
A novel use of time separation technique to improve flat detector CT perfusion imaging in stroke patients
Vojtěch Kulvait, Philip Hoelter, Robert Frysch +3
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 help reduce…
Contrast-to-noise ratio analysis of microscopic diffusion anisotropy indices in q-space trajectory imaging
Jan Martin, Sebastian Endt, Andreas Wetscherek +5
Diffusion anisotropy in diffusion tensor imaging (DTI) is commonly quantified with normalized diffusion anisotropy indices (DAIs). Most often, the fractional anisotropy (FA) is use…
MRzero -- Fully automated discovery of MRI sequences using supervised learning
Alexander Loktyushin, Kai Herz, Nam Dang +7
Purpose: A supervised learning framework is proposed to automatically generate MR sequences and corresponding reconstruction based on the target contrast of interest. Combined with…
