Abstract: An ultrasound diagnostic apparatus includes: a hardware processor that search for a blood vessel position of a subject in a tomographic image and automatically setting a region corresponding to the blood vessel position detected in the tomographic image as a measurement region for generating a Doppler image. In a case where a measurement region has been already set or in a case where a specified position specified by a user exists when the hardware processor automatically sets the measurement region, the hardware processor executes processing of searching for the blood vessel position such that the measurement region is automatically set near the measurement region that has been already set or the specified position.

Abstract: An ultrasound diagnostic apparatus transmits ultrasound toward a subject by driving an ultrasound probe in which multiple transducers are arranged in an array, receives a reception signal that is based on waves reflected within the subject from the ultrasound probe, and generates an ultrasound image. The ultrasound diagnostic apparatus includes: a scan control section that sets scan conditions so that trapezoidal scanning is performed by the ultrasound probe; and a transmission section that controls driving of the ultrasound probe based on the scan conditions. The scan control section sets the scan conditions so that the inter-acoustic line angles in or around the center of the ultrasound probe are smaller than the inter-acoustic line angles near the edges when viewed along the scan direction.
