    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.

    摘要: A method and system is disclosed which permits a user to save user defined viewing configuration, also referred to as a bookmark as a separately manipulatable or transferable entity without altering the underlying image data and maintaining, where desired, the association between the bookmark 200 and the underlying source image data. The disclosed system and method act to save the bookmark by saving the succession of system inputs, which, in conjunction with the system characteristics and system parameters, achieve the desired viewing configuration. Thereby, the disclosed system and method permits review of the inputs used to manipulate the image to confirm the process by which a diagnosis or anatomical measurement was made, permits the replay of a sequence for presentation or training purposes to effectively demonstrate not only the end result, but the methodology as well. The disclosed system and method further permits the user to save the system parameters as set for a desired given viewing configuration of a 4D image sequence in addition to or in lieu of saving the system inputs. In this way, the desired viewing configuration is preserved while maintaining the integrity of the underlying image data. In addition, the disclosed system and method further permit the user to maintain or terminate the association of the bookmark 200 with the entirety of the source image data, or just a portion thereof.
