Low-resolution prostate MR

MR-images of the prostate region from healthy volunteers acquired at Elekta unity MR-Linac at Uppsala University Hospital. Data from each volunteer consist of an initial T2-weighted scan, followed by a number of groups of paired low and high resolution data approximately 5 minutes apart with a 3D balanced steady state free precession sequence. The initial T2-image and all high resolution images are segmented by a single observer including prostate, bladder and rectum.

本数据集包含乌普萨拉大学医院（Uppsala University Hospital）医科达（Elekta）Unity MR直线加速器上采集的健康志愿者前列腺区域磁共振成像（Magnetic Resonance Imaging, MRI）数据。每位志愿者的数据集由一次初始T2加权扫描组成，随后为多组采用三维平衡稳态自由进动序列采集的配对低分辨率与高分辨率数据，各组数据采集间隔约5分钟。初始T2加权图像与所有高分辨率图像均由同一名观察者完成手动分割，分割范围涵盖前列腺、膀胱及直肠。
