An ultrasonic diagnostic apparatus according to the present invention includes: a transmitting section, which drives a probe that transmits an ultrasonic wave toward a subject; a receiving section, which receives an ultrasonic echo, produced by getting the ultrasonic wave reflected by the subject, through the probe, thereby generating a received signal; a property value calculating section for calculating property values of the subject based on the received signal over a period of time; a stability estimating section for sequentially estimating the degrees of stability of the property values that have been calculated over the period of time; and a presenting section for presenting the degrees of stability thereon.

Ultrasonic diagnostic apparatus

The present invention is for an ultrasonic Doppler blood flow measurement device with which high-speed computation is possible, even when a memory having the characteristic of different read/write speeds in the row direction and the column direction is used for the buffer memory when computing blood flow information, without being affected by the slower read/write speed. It is provided with a large capacity memory sectionthat is constituted by a memory that has a two-dimensional address space and different data read/write speeds in the row direction and the column direction of that address space, and that stores detection signals, a blood flow computation sectionthat calculates blood flow information from the detection signals, a small capacity memory sectionthat has the capacity of at least the data amount required for the blood flow computation sectionto compute any one depth point of an object to be examined, and a large capacity memory control sectionthat performs data transfer from the large capacity memory sectionto the small capacity memory sectionin the row direction only.
