PURPOSE For patients with intermediate- and high-risk prostate cancer, the seminal vesicles (SVs) are included in the clinical target volume (CTV). The purposes of this study are to investigate interfraction motion characteristics of the SVs and determine proper margins for online computed tomography image guidance. METHODS AND MATERIALS Twenty-four patients, each with 16 daily helical computed tomography scans, were included in this study. A binary image mask was used for image registration… CONTINUE READING
