Subject: CT Arthrogram Image Data of the Hip in Healthy Young Adults

In a recent study, we examined the mechanics of cartilage in the normal of hip of 10 healthy adult volunteers:

Harris MD, Anderson AE, Henak CR, Ellis BJ, Peters CL, Weiss JA:  Finite element prediction of cartilage contact stresses in normal human hips.  Journal of Orthopaedic Research, 30(7),  2012.  DOI:  http://dx.doi.org/10.1002/jor.22040

We have made the de-identified CT arthrogram datasets available for other researchers to download at this address:

http://mrl.sci.utah.edu/software/hip-image-data

These datasets were acquired as part of a research project on the biomechanics of hip dysplasia (NIH #R01AR053344).  Healthy young adults consented to receive a CT arthrogram of one hip joint.  The image datasets include the pelvis and proximal femur.  One hip joint has been injected with a contrast agent to facilitate delineation of intra-articular cartilage layers.  The contralateral hip joint is also visible.

Details about the subjects, CT scan settings, and image resolution can be found at the same address.

If you have not registered on the MRL site previously, you will be asked to create an account.  Registration allows us to keep track of the use of the image data (number of downloads, who, where).  Your registration information is safe and will not be redistributed.

Separate files are available for each of the 10 subjects.  Each file is a Linux tape archive (tar) file, compressed with GNU Zip (gzip).  Thus each file has the ending “.tar.gz”.  The size of each file is approximately 3 GB.

If you make use of one or more of these datasets in your research, we ask that you please reference the Harris et al. manuscript listed above.

Kind regards,
