Stented Abdominal AortaCT Scan of the abdomen and pelvis. The dataset contains also a stent in the abdominal aorta. No contrast agent was used to enhance the blood vessels.512x512x174 (87.0 MB)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

BunnyA CT scan of the Stanford Bunny. The greyscale units are Hounsfield units, denoting electron-density of the subject; the scale units are in millimeters. The scan was completed 28 January 2000.512x512x361 (180.5 MB)Download
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.
Neurons in Marmoset Visual CortexPyramidal neurons in the marmoset primary visual cortex (V1) labeled with green fluorescent protein (GFP) after injection of a psuedotyped G-deleted rabies virus in area V2. The tissue was cleared using the Sca/e technique and imaged on a Olympus 2-photon microscope at 20x magnification.1024x1024x314 (314.0 MB)Download

Pawpawsaurus CampbelliThis specimen, the holotype, was collected from the Paw Paw Formation, SMU Loc. No. 263, Tarrant County, Texas. The specimen was scanned along the coronal axis for a total of 1088 slices. Voxel size is 0.2275 mm.958x646x1088 (1.3 GB)Download
Spathorhynchus FossoriumThis specimen, the holotype, was collected from the Middle Eocene Green River Formation of Sweetwater County, Wyoming on 27 July 1967 by Frank L. Pearce. The specimen was scanned along the coronal axis for a total of 750 slices. Each 1024x1024 pixel slice is 0.047 mm thick, with an interslice spacing of 0.047 mm and a field of reconstruction of 22 mm.1024x1024x750 (1.5 GB)Download

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
