Dynamic perfusion imaging is routinely used in the diagnostic workup of acute ischemic stroke (AIS). At present, perfusion imaging can also be performed within the angio suite using flat detector computed tomography (FDCT). However, higher noise level, slower rotation speed and lower frame rate need to be considered in FDCT perfusion (FDCTP) data processing algorithms. The Time Separation Technique (TST) is a model-based perfusion data reconstruction method developed to solve these problems. In…

An improved noise and artefact reduction compared to existing post-processing methods and faster computation speed compared to an algebraic reconstruction method are achieved.
Dynamic Iterative Reconstruction for Interventional 4-D C-Arm CT Perfusion Imaging
A dynamic, iterative reconstruction (DIR) approach to reconstruct TACs described by a weighted sum of basis functions is presented, and a regularization technique based on joint bilateral filtering (JBF) is introduced to reduce noise.
Time separation technique: Accurate solution for 4D C‐Arm‐CT perfusion imaging using a temporal decomposition model
The algorithm presented here provides a solution for resorting to model- based perfusion reconstruction without its connected high computational cost and is potentially able to have recourse to the benefit from model-based perfusion imaging for practical application.

Reproducibility of quantitative CT perfusion imaging.
CT perfusion imaging is easily performed on conventional modern CT equipment and demonstrates little variability in measures of absolute cerebral blood flow within individuals when studied on two occasions within 24 h.
Differences in CT perfusion maps generated by different commercial software: quantitative analysis by using identical source data of acute stroke patients.
CT perfusion imaging maps were significantly different among commercial software even when using identical source data, presumably because of differences in tracer-delay sensitivity.
An Enhanced SMART-RECON Algorithm for Time-Resolved C-Arm Cone-Beam CT Imaging
Temporal resolution in time-resolved cone-beam CT (TR-CBCT) imaging is often limited by the time needed to acquire a complete data set for image reconstruction. With the recent developments of
