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…
Software Implementation of the Krylov Methods Based Reconstruction for the 3D Cone Beam CT Operator
Vojtěch Kulvait, Georg Rose
Krylov subspace methods are considered a standard tool to solve large systems of linear algebraic equations in many scientific disciplines such as image restoration or solving part…
Cutting Voxel Projector a New Approach to Construct 3D Cone Beam CT Operator
Vojtěch Kulvait, Julian Moosmann, Georg Rose
We introduce a novel class of projectors for 3D cone beam tomographic reconstruction. Analytical formulas are derived to compute the relationship between the volume of a voxel proj…
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…
