3D Shepp-Logan phantom

April 13th, 2008 Posted in Data and sources

Shepp-Logan phantom is well-known imitation of human cerebral. CT researchers use of Shepp-Logan for testing and demonstrate reconstruction quality of their CT algorithms.

Here, there are 3 different 2D middle slices (XY, XZ, YZ) and one 3D slice of modified 3D Shepp-Logan phantom. Modified phantom differ from original phantom with more contrast colors. Original phantom has more realistic colors.

In many cases only 2D Shepp-Logan phantom needed, but sometimes 3D image required. If you have an installed MatLab, you can use phantom3d.m m-file (by Matthias Schabel) to generate different 3D Shepp-Logan phantoms. This m-file you can find at http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=9416

If you haven’t got installed MatLab, you can download here 3D phantoms in raw data format. All data are in unsigned 16 bit format with data written one by one for all 3 dimensions.
