前列腺癌是影响老年男性的最常见癌症。前列腺癌的传统非影像筛查测试如前列腺抗原（PSA）和直肠指检（DRE）测试通常缺乏特异性。在所有可用于前列腺癌诊断的筛查成像方式中，超声是最常用、廉价、非侵入性且无辐射的成像方式。超声图像中前列腺轮廓的精确分割对于活检过程中针的精确放置、计算前列腺体积以及定位前列腺癌等应用至关重要。此外，将放射性粒子植入前列腺区域的低剂量率（LDR）近距离放射治疗需要在超声图像中精确描绘前列腺轮廓。因此，准确分割前列腺区域对于诊断和治疗非常重要。本文旨在分析用于经直肠超声 (TRUS) 图像中前列腺分割的现有方法。在本次调查中，详细讨论并比较了使用平均绝对距离、豪斯多夫距离和时间等标准提取前列腺的不同分割方法。 (C) 2017 Elsevier B.V. 保留所有权利。
Prostate cancer is the most common cancer that affects elderly men. The conventional non-imaging screening test for prostate cancer like prostate antigen (PSA) and digital rectal examination (DRE) tests generally lack specificity. Ultrasound is the most commonly available, inexpensive, non-invasive, and radiation-free imaging modality among all the screening imaging modalities available for prostate cancer diagnosis. The precise segmentation of prostate contours in ultrasound images is crucial in applications such as the exact placement of needles during biopsies, computing the prostate gland volume, and to localize the prostate cancer. Moreover, the low-dose-rate (LDR) brachytherapy treatment in which radioactive seeds are implanted in the prostate region requires accurate contouring of the prostate gland in ultrasound images. Therefore, it is very important to segment the prostrate region accurately for the diagnosis and treatment. This paper aims to present the analysis of existing approaches used for the segmentation of prostate in transrectal ultrasound (TRUS) images. In this survey, different segmentation methods used to extract the prostrate using criteria such as mean absolute distance, Hausdorff distance and time are discussed in detail and compared.
