Focused Ultrasound Surgery is gaining impetus as a non-invasive ablation modality for treatment of deep seated tumors and cancers over the years. The main advantages lie in its ionization free nature over other prevalent modalities for ablation. However, due to the ability of irreversible damage, it is extremely important to understand the multi-physics of parametric influence in dose selection and planning as well as implementing precise and accurate targeting means for selective desirable damage. This paper deals with the field modelling of ultrasonic sources, lesion formation and subsequent thermal distribution studies during the lesioning process for liver cancer targets.
