Abstract: The goal of radiotherapy for treating cancer patients is to irradiate cancerous tissues while avoiding irradiation of healthy tissues surrounding the tumor. To that end, the volume to be irradiated is contoured on volumetric images of the patient (CT, MRI, PET), which is referred to as target volume definition. The presentation will introduce the two target volume concepts used in radiotherapy: gross tumor volume (GTV) and clinical target volume (CTV). The GTV represents the macroscopic tumor mass that appears abnormal on medical images. The CTV represents the volume that may contain microscopic extensions of the tumor, which are not visible in the image. The presentation will illustrate target volume definition for a few tumor sites and then discuss the contributions that computer vision and medical image computing may provide to support this task.
