PURPOSE AND BACKGROUND The purpose was to validate the accuracy of motion models derived from deformable registration from four-dimensional computed tomography (4DCT) and breath-hold contrast enhanced computed tomography (BHCCT) scans for liver SBRT. Additionally, the image quality of the time averaged mid-position (MidP) CT constructed using the detected motion model was assessed. MATERIALS AND METHODS 4DCT and BHCCT liver scans of 11 patients were acquired with 1 or 2 fiducial markers… CONTINUE READING
