ULTRASOUND DIAGNOSTIC DEVICE, ULTRASOUND DIAGNOSTIC DEVICE CONTROL METHOD, AND ULTRASOUND DIAGNOSTIC DEVICE CONTROL APPARATUS

摘要

In an ultrasound diagnostic device, when an operation inputter receives operation input instructing to change a D-mode image to be displayed while a D-mode image is frozen or cine-played back, an image controller newly generates a D-mode image and a trace waveform with respect to another partial range on the time axis of Doppler spectrum data in accordance with the operation input, and controls a display device to display the generated D-mode image, a cardiac cycle period selector detects cardiac cycle periods shown in the newly generated D-mode image from the generated trace waveform, and selects at least one cardiac cycle period from among the detected cardiac cycle periods as a measurement target cardiac cycle period according to a selection criterion, and a measure measures a diagnostic parameter with use of part of the generated trace waveform corresponding to the selected measurement target cardiac cycle period.
