CT data

On this page you can gain access to a database of CT images and projection data for the images, that can be used for making reconstruction algorithms. Data for some phantom objects and various programs for artificial phantoms and data projections are also given here.

The clinical images shown on these pages have been obtained from the Visible Human Project. They were created from scanning a human cadaver with CT and MRI scanners and then subsequently slicing the cadaver into 1 mm sections for taking photographs.

A further description of the data can be found at here and a description of the program can be found here.

You can get to the different data pages by clicking on one of the images or the text below them.
