NCI-ISBI 2013 Challenge: Automated Segmentation of Prostate Structures (ISBI-MR-Prostate-2013)

This data set was created for use in the NCI-ISBI 2013 Challenge - Automated Segmentation of Prostate Structures. The challenge data set was divided into 3 parts including training, leaderboard and test data sets. This allowed participants to prepare their algorithms and test their results prior to submitting to a final test phase for selecting the winner.

Image data were selected from PROSTATE-DIAGNOSIS and Prostate-3T collections on TCIA. Cases consist of axial scans with half obtained at 1.5 T (Philips Achieva) with an endo-rectal receiver coil (fromBostonMedicalCenter) and the other half at 3T (Siemens TIM) with a surface coil (from Radboud University Nijmegen Medical Centre [RUNMC],Netherlands). They were acquired as T2-weighted MR axial pulse sequences with either 4 mm thick slices at 3T or 3 mm thick at 1.5T.
Each case has had central gland (CG) and peripheral zone (PZ) outlines marked by NB and MR, or HH, GL, or JF.

本数据集专为NCI-ISBI 2013挑战赛——前列腺结构自动分割任务（NCI-ISBI 2013 Challenge - Automated Segmentation of Prostate Structures）打造。该挑战赛数据集划分为训练集、排行榜测试集与正式测试集三个部分，以便参赛选手先完成算法研发与结果验证，再提交至最终测试阶段以决出优胜者。
本次影像数据取自癌症影像档案库（The Cancer Imaging Archive, TCIA）中的PROSTATE-DIAGNOSIS与Prostate-3T数据集。所有病例均采用轴向扫描序列，其中半数使用1.5T场强的飞利浦Achieva扫描仪，并搭配直肠内接收线圈（数据来自波士顿医学中心）；另一半采用3T场强的西门子TIM扫描仪，搭配体表线圈（数据来自荷兰拉德堡德大学奈梅亨医学中心[Radboud University Nijmegen Medical Centre, RUNMC]）。
所有扫描序列均为T2加权磁共振轴向脉冲序列，其中3T场强下的切片厚度为4mm，1.5T场强下为3mm。
每例病例的中央腺体（central gland, CG）与外周带（peripheral zone, PZ）轮廓均由NB、MR或HH、GL、JF完成标注。
