Henak CR, Abraham CL, Anderson AE, Maas SA, Ellis BJ, Peters CL, Weiss JA: Patient-specific Analysis of Cartilage and Labrum Mechanics in Human Hips with Acetabular Dysplasia. Osteoarthritis and Cartilage. 2014. This will create a subdirectory containing all of the image data files for the particular subject in DICOM format, as well as a copy of the license agreement and this file. Each image file represents one slice of the image dataset. Both gzip and tar are available for Windows, and there are a number of free software tools that can extract .tar.gz files under Windows. The image files have the extension “.dcm”. Many image processing, segmentation and visualization programs can open these DICOM files directly. The free software ImageJ is one option: http://rsbweb.nih.gov/ij/ To open an image stack in Image J, choose “Import” from the “File” menu, and then choose “Image Sequence”. Choose the first image in the stack and then click “Open”. CT images were acquired at the University of Utah Hospital. Each subject with acetabular dysplasia was being seen at the University of Utah Orthopedics Center for hip pain. The hip which was being evaluated clinically was selected for CT arthrogram. The hip capsule was injected with ~20 ml of contrast agent (2:1 Xylocaine to OMNIPAQUE® 350, GE Healthcare Inc., Princeton, NJ) under fluoroscopic guidance. CT images of both femurs and the entire pelvis were acquired following injection of the contrast agent. Joint traction was applied during the CT scan using a hare traction device. The images below indicate the bone and cartilage regions in the image data. CT images were resampled to improve the resolution of the segmentation masks. Resampled images are provided for download. All images have a resampled in-plane resolution of 1536 × 1536, an original in-plane resolution of 512 × 512 and a bit depth of 16.Repository for Image Data of Traditional Dysplastic Subjects
