Problems solved by technology

[0005] Therefore, when a tumor image is displayed in the B-mode image display area on the display surface of the image display, if the blood flow display area is to be moved to a part where the tumor image exists to display the blood flow of that part, if When the blood flow display area overlaps with the tumor image during the movement, the tumor image is covered and cannot be seen, and the target cannot be confirmed
[0006] Usually, the ultrasonic transceiver (transmitter) such as an ultrasonic probe is touched by the operator to the subject, so the direction is easy to change
Therefore, it is necessary to correct the direction deviation of the transceiver while viewing the screen so that the tumor image always appears on the display screen. However, if the target is invisible in the middle as described above, even if the direction of the transceiver deviates, it cannot be corrected.
As a result, it is uncertain whether the blood flow displayed in the blood flow display area must be the blood flow of the desired part

Abstract

By the configuration, an observation target of which blood state needs to be grasped can be always optimally observed in real time in a Doppler image by a Color Doppler mode or a Power Doppler mode.In the present invention, an image processing device is configured by including an ultrasonic wave transmitting section, an ultrasonic wave receiving section, a transmission and reception control section, a B mode signal processing section, a B mode image generating and storing section, an image synthesizing section, a Doppler signal processing section, a Doppler image generating and storing section, a Doppler scan region setting section, a Doppler scan region storing section, a Doppler scan control section, a region marker movement control section and a region marker image generating section.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus for displaying a blood flow image in a part of a B-mode image display area in a color Doppler mode or a power Doppler mode using ultrasonic waves. Background technique [0002] In recent years, in medical ultrasonic diagnostic apparatuses, a living body is irradiated with ultrasonic waves, and the energy (power) of Doppler (Doppler) signals is used to display the two-dimensional distribution of blood flow in a color image. The method of using the energy of the Doppler signal to display the blood flow is different from the method of using the frequency of the Doppler signal to display the blood flow. Although the direction, velocity or velocity dispersion of the blood flow cannot be displayed, but in view of the high sensitivity and The unique function of displaying the position and intensity of blood flow with a high S / N ratio has become one of the useful blood flow display methods. ...
