Pancreas-CT

<p>The National Institutes of Health Clinical Center performed 82 abdominal contrast enhanced 3D CT scans (~70 seconds after intravenous contrast injection in portal-venous) from 53 male and 27 female subjects. Seventeen of the subjects are healthy kidney donors scanned prior to nephrectomy. The remaining 65 patients were selected by a radiologist from patients who neither had major abdominal pathologies nor pancreatic cancer lesions. Subjects' ages range from 18 to 76 years with a mean age of 46.8 ± 16.7. The CT scans have resolutions of 512x512 pixels with varying pixel sizes and slice thickness between 1.5 − 2.5 mm, acquired on Philips and Siemens MDCT scanners (120 kVp tube voltage).</p><p>A medical student manually performed slice-by-slice segmentations of the pancreas as ground-truth and these were verified/modified by an experienced radiologist.</p>国家健康研究院临床中心对53名男性和27名女性受试者进行了82次腹部对比增强3D CT扫描（注射静脉对比剂后约70秒，处于门静脉期）。其中17名受试者为健康肾脏捐赠者，在肾切除术前的扫描。剩余的65名患者由放射科医生从无重大腹部病理学或胰腺癌病变的患者中选取。受试者的年龄范围在18至76岁之间，平均年龄为46.8 ± 16.7岁。CT扫描分辨率为512x512像素，像素大小和切片厚度在1.5 − 2.5毫米之间，使用Philips和Siemens的多排螺旋CT扫描仪（管电压120 kVp）进行采集。一名医学实习生手动进行了胰腺的逐层分割作为基准，并由经验丰富的放射科医生进行验证/修改。

背景概述

Pancreas-CT数据集包含82个腹部增强3D CT扫描，来自80名受试者（53男27女），年龄范围18-76岁，主要用于胰腺分割研究。扫描数据由专业医疗设备采集，分辨率统一为512x512像素，但像素大小和切片厚度略有差异。数据标注由医学生手动完成并经过放射科医生审核，确保了高质量的真实标签，适用于医学图像分析任务。
