Abstract

Radiotherapy is a tumor treatment process using high dose of radiation. Hence, it is essential that radiotherapy is carefully planned with a Treatment Planning System (TPS). The first step in TPS is delineation that aims to get a better picture of the tumor and the target volume value. This research investigated volume target delineation for brain tumor against the MRI image of the head in axial position. Calculated target volumes include GTV (Gross Tumor Volume), CTV (Clinical Target Volume), PTV (Planning Target Volume), and OAR (Organ at Risk). Images were segmented using the active contour method. Segmentation result from each Slice is then calculated for its area, which then in turn, integrated to get the target volume. This research yields calculated volume and 3D visualization of each target. These two parameters are parts of a Treatment Planning System (TPS) used as a guideline in radiotherapy.
