Many many thanks to Geoff Rubin who helped me to scan the data, Sandy Napel who coordinated the scan and helped to process the data, and Marc Levoy who graciously provided the subject. Geoff and Sandy are with Stanford Radiology, and Marc is with Stanford Computer Science.
Cardiac Volume (Porcine)Volumes were obtained by way of computed tomography (CT) imaging on excised, postmortem porcine hearts. Alginate curing agents were injected into ventricles to provide rigidity and radiopaque agents were injected into the coronary arteries to distinguish microvasculature from the rest of the tissue.2048x2048x2612 (20.4 GB)Download

PancreasFirst scan. 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). A medical student manually performed slice-by-slice segmentations of the pancreas as ground-truth and these were verified/modified by an experienced radiologist.240x512x512 (120.0 MB)Download
