    摘要: A system and method for selecting a patient-specific frequency for ultrasound therapy of a target within the patient are provided. The method includes: (a) for at least one segment of an ultrasound transducer and for each of a plurality of ultrasound frequencies within a test range, sonicating the target and measuring a parameter correlated with an amount of ultrasound energy absorbed in the target; and (b) for each said at least one segment, selecting for subsequent ultrasound therapy, among the frequencies within the test range, a frequency corresponding to a value of the measured parameter that itself corresponds to a maximum amount of ultrasound energy absorbed in the target.

    摘要: Skull inhomogeneity may be quantified in accordance with the skull density measured in skull images acquired using a conventional imager; the quantified inhomogeneity may then be used to determine whether the patient is suitable for ultrasound treatment and/or determine parameters associated with the ultrasound transducer for optimizing transskull ultrasound treatment.

    摘要: Ultrasound energy is delivered to a patient in a controlled manner using a focused ultrasound system, thus maintaining the desired therapeutic effect without causing unwanted damage to surrounding tissue. An ultrasound transducer device includes multiple transducer elements, each of which is controlled by drive circuitry and a drive signal controller. An acoustic detector detects signals indicative of cavitation in tissue targeted by the transducer elements, and the drive signal controller manages the delivery of acoustic energy from the transducer elements based on the detected cavitation signals such that a therapeutic effect at the target tissue remains within an efficacy range.
