    摘要： A method for treating a desired volume of tissue using HIFU or other energy modality to ablate 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 one embodiment, the pattern of elemental treatment volumes are arranged to form a shell which partially or wholly encapsulates the desired volume of tissue, which then necroses in situ due to effects other than direct HIFU damage (including some combination of ischemia, thermal conduction, inflammation, apoptosis, etc.). The necrosed tissue remains in the body and is subsequently resorbed and/or healed via normal body mechanisms.

    摘要： HIFU therapy to a desired tissue site is controlled based on detected changes in one or more characteristics of a received backscatter signal resulting from exposure of the tissue to HIFU or other interrogation signals. In one embodiment, the bloom of backscatter signals outward from a treatment region (e.g., towards the HIFU transducer) is detected and monitored. Once the bloom reaches a predetermined location, treatment is stopped. Other signal characteristics such as angular distribution of frequency components in the backscatter signal, changes in reflection, power required to saturate a tissue characteristic, changes in attenuation and changes in a cumulative energy distribution function of the backscatter signal that change as a result of the application of HIFU power are also used to control the delivery of HIFU signals in accordance with other embodiments of the disclosed technology.

    摘要： A system and method for adjusting or selecting the treatment parameters for HIFU signals to treat a target treatment site, and/or to aid in visualizing the likely degree and location of HIFU effects on patient tissue. The system transmits one or more test signals into patient tissue and receives signals created in response to the test signals. The signals are analyzed to determine a response curve of how a characteristic of the signal varies with the one or more test signals. The response curve of the detected signals is used to select a treatment parameter.

    摘要： A system and method for dynamically adjusting the energy of HIFU signals delivered to a patient, and/or to aid in visualizing the likely degree and location of HIFU effects on patient tissue. The system transmits a HIFU signal into a patient and receives echoes therefrom. The echo signals are analyzed to determine the energy of the signals in a first range, such as at one or more harmonics and/or sub-harmonics of the fundamental frequency of the HIFU signal, and energy of the echo signals in a second range such as at the fundamental frequency of the HIFU signal. Based on the comparison, the energy and/or focus of the HIFU signals delivered to the patient is adjusted. An image of the compared echo signal powers in two or more frequency ranges may also be displayed for a user or used to adjust the focus point of the HIFU signals.
