Description

<p>In this study, we investigated the segmentation and registration methods to develop an intraoperative cancer localization navigation system to support complete resection of prostate cancer. segmentation using YOLACT++ was very accurate in the prostate. YOLACT++ was able to segment the prostate with very high accuracy, and it was also able to obtain sufficient accuracy for the outline of the tumor near the capsule of prostate. Therefore, we evaluated the effectiveness of YOLACT++ for cancer localization prediction. For registration, we compared the accuracy of affine transformation and projection transformation, and evaluated that affine transformation was effective. In the future, we will examine the accuracy of nonlinear registration methods such as the B-spline method and registration methods between different modalities.</p>
