FREQUENCY OPTIMIZATION IN ULTRASOUND TREATMENT

摘要

In ultrasound therapy, the frequency of sonications can be optimized, within a certain frequency range, to maximize the absorption or the acoustic intensity at the target in a manner specific to the patient.

主权项

1. A patient-specific frequency-optimization method for ultrasound therapy of a target within the patient, the method comprising:
(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.
