NON-RIGID MR-CT IMAGE REGISTRATION: This tutorial demonstrates how to perform MR-CT and CT-CT non-rigid registrations. In a cryoablation of liver case, we can see a tumor on pre-operated MRI. However, on intra-operated CT image, the tumor can not be seen though cryoproves can be seen. By using non-rigid MR-CT image registration, we can check the distance between the cryoprobes and tumor as shown the figure.

PROCESS OF IMAGE REGISTRATION IN CRYOABLATION OF LIVER CASE: Registration process between MR and CT images in cryoablation of a liver case is shown. (1) A transformation matrix T1 was used to deform the pre-procedure contrast enhanced MR image on to the planning CT image. (2) T2 was used to deform the planning CT image on to the intra procedure CT image with cryoprobes. (3) The matrix T2 was combined with T1 to deform the MR image onto the CT image with cryoprobe.
