    Detection and localization of the prostate cancer is difficult problem in general case. For this purpose the new method of medical imaging named perfusion computed tomography (p-CT) can be used. Nevertheless images registered by means of p-CT technology are difficult for interpretation, especially when interpretation must be earned by computer instead of experienced professional radiologist. In paper new algorithms for p-CT images automatic interpretation are presented and discussed. Using proposed algorithms both detection and localization of the prostate cancer can be performed. After general description of proposed methods illustrative case study is presented. For proper solution of the problem under consideration the original method for region of interest (ROI) localization is proposed. Such method named 'life belt method' can be assessed as simple and effective and therefore it can be recommended for analysis of perfusion computed tomography prostate cancer images.
