Provided is an ultrasound diagnostic apparatus for obtaining a tomographic image of a subject by transmitting and receiving an ultrasound with an ultrasound probe, the ultrasound diagnostic apparatus including: a hardware processor that: causes transmission and reception of an ultrasound for a probe element check with respect to each of a plurality of piezoelectric elements included in the ultrasound probe; converts signal features of reception signals obtained respectively in the plurality of piezoelectric elements at the time of the probe element check into image information indicating deterioration degrees of the plurality of piezoelectric elements, separately; and displays, based on a result of the conversion, a probe-condition mapping image expressed in a bar form by mapping images indicating the deterioration degrees of the plurality of piezoelectric elements in a row according to an arrangement of the plurality of piezoelectric elements in the ultrasound probe.

Ultrasound diagnostic apparatus, method of controlling ultrasound diagnostic apparatus, and non-transitory computer-readable recording medium storing therein computer-readable program for controlling ultrasound diagnostic apparatus

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.

Ultrasound diagnostic technique for setting virtual origins of acoustic lines for trapezoidal scanning

First transmission information in which an optimum transmitting voltage and a transmitting waveform are associated with each other for each display mode, and second transmission information in which a plurality of transmitting voltage candidates and pulse-width modulation transmitting waveforms that are pulse-width-modulation controlled to respectively correspond to the plurality of transmitting voltage candidates are associated with each other for each display mode are used to extract a maximum transmitting voltage candidate that does not exceed an optimum transmitting voltage of a first display mode from a plurality of transmitting voltage candidates included in the second transmission information of a second display mode so as to determine a common transmitting voltage used in common for the first display mode and the second display mode based on the optimum transmitting voltage of the first display mode and/or the maximum transmitting voltage candidate.

Ultrasound diagnostic apparatus, a transmission condition setting method, and program

An ultrasound diagnostic apparatus includes an ultrasound image acquirer, an evaluation target determiner, a disease progression score calculator, a selector, and a display controller. The ultrasound image acquirer acquires ultrasound image signals of a plurality of frames. The evaluation target determiner analyzes the ultrasound image signal of each frame and determines the frame to be an evaluation target frame when the ultrasound image signal includes a target image section depicting a joint. The disease progression score calculator calculates, for each evaluation target frame, a disease progression score quantifying disease activity using an ultrasound image signal of the target image section included in the ultrasound image signal of the evaluation target frame. The selector selects at least one disease progression score in accordance with a predetermined numerical process. The display controller controls the display to display the selected disease progression score and an ultrasound image of a corresponding frame.
