Georg Schramm, Ahmadreza Rezaei, Kris Thielemans +1
These proceedings contain the presented papers at the 16th International Meeting on Fully Three-Dimensional Image Reconstruction in Radiology and Nuclear Medicine 2021, which was t…
A Motion Compensation Approach for Oral and Maxillofacial Cone-beam Imaging
Tao Sun, Reinhilde Jacobs, Ruben Pauwels +3
Purpose: Patient movement affects image quality in oral and maxillofacial cone-beam CT imaging. While many efforts are made to minimize the possibility of motion during a scan, rel…
Regional accuracy of ZTE-based attenuation correction in static and dynamic brain PET/MR
Georg Schramm, Michel Koole, Stefanie M. A. Willekens +7
Accurate MR-based attenuation correction (MRAC) is essential for quantitative PET/MR imaging of the brain. In this study, we analyze the regional bias caused by MRAC based on Zero-…
