Focused Ultrasound of Liver
This chapter examines the use of high-energy focused ultrasound as a method of thermal ablation of liver tumors. This modality holds out the promise of destroying liver tumors without any invasion across the skin at all so that patients could be treated as an outpatient and yet still have substantial destruction of their liver tumor created without any damage to adjacent tissue.
Various manifestations of this technology are discussed, and the potential of using MR guidance to improve safety and accuracy with online thermal mapping helping to visualize tissue response is described. Technological innovations required to take this modality forward to become a clinical reality are described as well as early work in this field.
