Abstract
A method and system for treating a desired volume of tissue using HIFU or other energy modality includes ablating a pattern of elemental treatment volumes each having a volume that is greater than that of the focal zone of the HIFU transducer but smaller than the overall volume of the desired treatment volume. In at least one embodiment, the elemental treatment volumes are arranged to form a shell which partially or wholly encapsulates the desired volume of tissue, which then necroses in situ. The elemental treatment volumes are created by distributing HIFU energy in multiple doses with repeated passes of the focal zone of the HIFU transducer in a trajectory over or along a perimeter of each elemental treatment volume.
