Model-Based Perfusion Reconstruction with Time Separation Technique in Cone-Beam CT Dynamic Liver Perfusion Imaging
Hana Haseljić, Robert Frysch, Vojtěch Kulvait +6
The success of embolisation, a minimally invasive treatment of liver cancer, could be evaluated in the operational room with cone-beam CT by acquiring a dynamic perfusion scan. The…
Liver Segmentation in Time-resolved C-arm CT Volumes Reconstructed from Dynamic Perfusion Scans using Time Separation Technique
Soumick Chatterjee, Hana Haseljić, Robert Frysch +9
Perfusion imaging is a valuable tool for diagnosing and treatment planning for liver tumours. The time separation technique (TST) has been successfully used for modelling C-arm con…
Effect of an advanced model-based iterative reconstruction algorithm on texture and visual impression of images privieded by a dual source CT scanner
Babak Alikhani PhD, Thomas Werncke MD, Hans-Jürgen Raatschen MD +2
Purpose: To evaluate the influence of ADMIRE algorithm on image texture and image visual impression as a supplement to measurements of common image quality parameters such as noise…
Influence of patient alignment on image quality provided by a C-arm flat-panel detector computer tomography: a phantom study
Babak Alikhani, Frank Wacker, Thomas Werncke
Purpose: The aim of this phantom study was to evaluate the influence of patient alignment on the image quality by a C-arm flat-panel detector computer tomography (CACT). Materials…
