This dataset contains X-ray computed tomography (CT) and fluoroscopy data collected during the research and development of computer-integrated surgical systems for periacetabular osteotomy procedures. A minimum of two CT scans, preoperative and postoperative, are included for each of six cadaveric specimens. Fluoroscopy taken before, during and after, osteotomy is also included for each specimen. CT and fluoroscopy data of an artificial tracking fiducial object and a sawbones pelvis are included as well. All told, the original Digital Imaging and Communications in Medicine (DICOM) files from 19 CT scans and 2,659 fluoroscopic images are included. This report, along with a supplementary spreadsheet, contains a detailed explanation of the data. It is our hope that this documented dataset will accelerate the research and development of other new methods for image-guided interventions.
