In February, members of the CT CIC took part in the SPIE Medical Imaging 2022 conference. Whether in person or virtually, it is always a privilege to present our findings to the world, and this year in San Diego and online was no exception.

2022 was a particularly productive year, with 14 proceedings papers produced in part or fully by CT CIC members. See below for a full list, with links to the manuscripts.
