Abstract: An ultrasonic Doppler diagnostic apparatus sends ultrasonic waves to a specimen, receives a reflection signal of the ultrasonic waves from the specimen to detect a Doppler signal, obtains blood flow information indicating a peak flow velocity of coronary blood flow, and displays the flow velocity information before and after the administration of a drug to the specimen on a display unit. Then, at least velocity ranges of the flow velocity information before and after the administration of the drug to the specimen are adjusted, and during an ultrasonic scan of the specimen, data on a plurality of acquired images having different velocity ranges are adjusted to the same velocity range. A system control unit displays the data on the plurality of images adjusted to the same velocity range on the display unit.

Abstract: A measurement data processing device measures a size of a diagnostic region from a tomographic image as two-dimensional information. An ROI width determining device determines a size of a region of interest based on the size (lateral width and longitudinal width) of the diagnostic region. An oscillation angle determining device determines a range of an angle for oscillating ultrasonic transducers based on the size. An oscillation rate determining device determines a rate for oscillating the ultrasonic transducers based on information indicating the oscillation angle and image quality. In order to acquire a three-dimensional image of the diagnostic region, the probe oscillation control device controls the oscillation of the ultrasonic transducers based on the information. A three-dimensional image processing device extracts a three-dimensional image of in the determined region of interest from the acquired three-dimensional image. A display device displays the extracted three-dimensional image.
