The researchers' specific aims are to test the following hypotheses:

Hypothesis 1: A tumor can be completely ablated by ILT with MRI-guidance.

Hypothesis 2: The MRI-based 3D temperature map of tissue during ILT is predictive of destruction.

Hypothesis 3: The 3D "thermal dose" map that is based on the tissue's temperature over time is more predictive of tissue destruction than the temperature map.
