This study investigates the feasibility of directing cryotherapy probes using a body-mounted and motorized needle guidance device in abdominal MRI-guided cryoablation. Utilizing a motorized needle alignment device offers an alternative solution to the trial-and-error method of probe placement, as it allows one to directly orient cryotherapy probes, efficiently. This study found the method to be feasible for use in cryoablation in 3T with placement accuracy of 8.8mm. Further investigation is warranted to improve the efficiency of probe placement.
