摘要： The purpose of the present invention is to reduce as much as possible projection of ultrasound onto portions other than a treatment site. When a user designates a treatment range on a diagnostic image, a switch (12) selects a transmitter for treatment (16). Ultrasound with intensity for treatment is thereby transmitted from a probe (10) to the inside of an organism. When the treatment operation continues for a prescribed time, a control unit (18) controls the switch (12) to select a transmitter for diagnosis (14). The probe (10) thereby emits an ultrasound beam for diagnosis, senses an echo thereof, generates a diagnostic image, and carries out an inspection of a positional shift of the site to be treated. In the inspection, the control unit (18) compares the diagnostic image with a reference image (i.e., a diagnostic image taken when the treatment range is specified or when an immediately previous inspection was carried out), and if a significant difference is detected therebetween, determines that a shift has occurred, issues an alarm, and urges the user to correct the positional shift. It is possible to resume the treatment when the positional shift has been corrected.

摘要： The purpose of the invention is to find each component of a blood flow velocity using a simple process. In a secondary beam method, scanning is performed using Doppler measurement ultrasound beams (42) as primary beams, and Doppler measurement components are measured on the basis of the ultrasound waves received from the direction of each Doppler measurement ultrasound beam. Then, ultrasound waves forming secondary beams (58) at a direction that intersects the direction of the Doppler measurement ultrasound beams are sent and received, and the Doppler effect for the secondary beam direction component at the point of intersection of the Doppler measurement ultrasound beam (42) with the secondary beams (58) is measured. Furthermore, using the intersection point as the position for starting integration, an integration calculation based on the law of conservation of mass is performed along the route that intersects with the Doppler measurement ultrasound beams (42), and the component in the direction of the intersection route is found. The initial value for integration is the component in the direction of the intersection route of the integration start point (PA), and is found on the basis of the Doppler measurement component and the secondary beam direction component at the integration start point.
