Abstract

An object of the present disclosure is to reduce the number of times of transmitting ultrasound pulses while maintaining Doppler measurement performance for an ultrasound diagnostic apparatus. An intermittent transmission pattern determination method includes obtaining reference measurement information for reference transmission and intermittent measurement information for intermittent transmission, and obtaining error evaluation information representing a difference between the reference measurement information and the intermittent measurement information. The reference measurement information is information indicating a situation in which Doppler measurement information is obtained in a reference transmission operation. The intermittent measurement information is information indicating a situation in which the Doppler measurement information is obtained in an intermittent transmission operation. The reference measurement information and the intermittent measurement information may include a Doppler shift frequency. In addition, the reference measurement information and the intermittent measurement information may include information indicating a high-pass filter characteristic of a wall filter according to the number of received Doppler signal values, and aliasing characteristic information regarding the Doppler shift frequency.
