PROSTATEx Zone Segmentations

This collection contains prostate’s zonal segmentation for 98 cases randomly selected from the SPIE-AAPM-NCI PROSTATEx Challenge. The four-class segmentation encompasses the peripheral zone, transition zone, fibromuscular stroma and the distal prostatic urethra. As underlying images, we used transversal T2w scans. Segmentations were created by a medical student with experience in prostate segmentation and an expert urologist who instructed the student and double-checked the segmentations in the end. The DICOM representation of these segmentations were generated with dcmqi.

本数据集包含从SPIE-AAPM-NCI PROSTATEx挑战赛中随机遴选的98例病例的前列腺带区分割标注。其四分类分割任务涵盖外周带（peripheral zone）、移行带（transition zone）、纤维肌性基质（fibromuscular stroma）与前列腺远端尿道（distal prostatic urethra）四类解剖结构。该数据集的基础影像为横断面T2加权（T2w）扫描图像。本次分割标注由具备前列腺分割经验的医学生完成，并由指导该学生的泌尿外科专家最终进行双重审核与确认。上述分割标注的医学数字成像和通信（DICOM）格式文件由dcmqi工具生成。
