Abstract
An ultrasound treatment apparatus includes an ultrasound source for generating treatment ultrasound which is focused, a driving circuit for driving the ultrasound source to generate treatment ultrasound from the ultrasound source, and a controller for controlling to make the driving circuit drive the ultrasound source under an irradiation condition in which an optimization index obtained by the product of the focus intensity (W/cm2), the irradiation period (sec), and the frequency (MHz) all of the treatment ultrasound falls within an appropriate range from 6,000 (inclusive) to 40,000 (inclusive).
Claims31
An ultrasound treatment apparatus comprising:
- an ultrasound source for generating treatment ultrasound which is focused;
- a driving circuit for driving said ultrasound source to generate treatment ultrasound from said ultrasound source;
- and
- a controller for controlling said driving circuit to cause said driving circuit to drive said ultrasound source under an irradiation condition in which an optimization index obtained by a product of a focus intensity (W/cm2) of the treatment ultrasound, an irradiation period (sec) of the treatment ultrasound, and a frequency (MHz) of the treatment ultrasound falls within an appropriate range from 6,000 (inclusive) to 40,000 (inclusive).
