Ultrasonic diagnosis and treatment apparatus.

摘要

To provide an ultrasonic diagnostic apparatus for treating tumors used in combination with the phase-change ultrasound contrast agent. Using a phase-change-type ultrasound contrast agent, irradiated with phase change for ultrasonic phase-change ultrasonic-wave transmitting unit (18), a micro-bubble holding ultrasound microbubble holding ultrasonic transmission part (29) By irradiating and observing the phase changes using a (19) phase change detection for ultrasonic transmitting and receiving unit, is allowed to generate and retain the microbubbles previously needed treatment site (16) as a whole, the main treatment goal microbubbles site (16) as a whole, constitute an ultrasonic diagnosis and treatment device for irradiating the therapeutic ultrasonic waves from the transmitting unit (20) the therapeutic ultrasound moderate intensity of 1kW / cm ² or less.
