Abstract

The technological development of PET/CT scanners over the past 20 years has been staggering. Starting from a traditional PET/CT scanner, improvements on sensitivity, axial field of view, dose required, and speed of scan acquisition were all made. This allowed for the development of whole body PET/CT scanners such as the "Biograph Vision Quadra" that is presented with 2 modes of functionality, step-and-shoot and continuous bed motion. The research presented here aims to study the compliance of the CBM mode at varying speeds compared to its static counterpart using the EARL 2 parameters provided by EANM as a reference. Proper reconstruction parameters were also monitored and tested. The software 3D slicer was used for the image analysis. This report demonstrates the EARL compliance of the CBM modes whilst also finding the ideal reconstruction parameters required, in this case a 4 mm Gaussian filter. Moreover, the speed of image acquisition was also studied using a statistical test. Further research using more prominent samples or improved software will result in a better understanding of the proper parameters to be used allowing for multi center studies to take place with this new scanner.
