Automatic segmentation of the prostate and surrounding structures for image-guided radiotherapy
Richard J. Radke · 2003
The objective of this research is to build a computer algorithm that can automatically segment the prostate and surrounding structures to aid cancer treatment. To fully utilize the usefulness of Intensity Modulated Radiotherapy (IMRT), which can treat a region of interest with high accuracy, the daily position information about the objects of interest is necessary. Manual segmentation of a series of CT scan images by an oncologist before treatment is a time-consuming task. Therefore, a fast automatic segmentation algorithm would be of tremendous help in the process. The goal is to develop a fast algorithm that matches the segmentation accuracy of a human expert.
