Embodiment Construction
[0045] An embodiment of the present invention provides an ultrasonic device capable of emitting focused waves from multiple angles to perform blood flow imaging.
[0046] Such as figure 1 Shown is a structural block diagram of an ultrasonic device. Wherein, the ultrasound device 10 includes an ultrasound probe 110 , a sending / receiving controller 120 , a memory 130 , a processor 140 and a display 150 . The sending / receiving controller 120 may include a sending controller and a receiving controller, the sending controller is used to excite the ultrasonic probe 110 to transmit the focused ultrasonic beam to the target object, and the receiving controller is used to receive the focused ultrasonic beam returned from the target object through the ultrasonic probe 110 Ultrasound echo. The processor 140 may obtain an ultrasonic echo signal based on the ultrasonic echo of the focused ultrasonic beam, and process the ultrasonic echo signal.
[0047] Exemplarily, the sending controll...

The invention provides a speed determination method, an ultrasonic device and a computer storage medium. The speed determination method comprises the steps that focused ultrasonic beams are emitted to a target area in at least two directions, wherein the focused ultrasonic beams comprise a first number of scanning lines in the first direction, the focused ultrasonic beams comprise a second number of scanning lines in the second direction, and the second number is smaller than the first number; the ultrasonic echo is received to obtain ultrasonic echo signals along the first direction and the second direction correspondingly; a first speed value in the first direction and a second speed value in the second direction at intersection points of the first number of scanning lines and the second number of scanning lines are calculated according to the ultrasonic echo signals in the first direction and the second direction; and a velocity vector at the intersection location is determined. When the focused ultrasonic beams are emitted in multiple directions, the number of the scanning lines in the second direction is smaller than the number of the scanning lines in the first direction, and compared with traditional color ultrasound, the speed vector can be obtained in the invention, and meanwhile the frame rate can be prevented from being excessively reduced.
Description
technical field [0001] The invention relates to the medical field, and more specifically relates to a method for determining speed, an ultrasonic device and a computer storage medium. Background technique [0002] In the process of obtaining the ultrasound vector blood flow image, the use of multi-angle deflection transmission will lead to a decrease in the frame rate (FR), and the more the number of angles, the lower the display frame rate. [0003] The frame rate of the plane wave or divergent wave itself is relatively high, even if multi-angle deflection is used, the frame rate after synthesis can still reach hundreds of hertz (Hz). However, the frame rate of the focused wave itself is not high. After multi-angle deflection is used, the frame rate after synthesis may be less than ten Hz, which is difficult to meet the needs of faster blood flow imaging, such as carotid artery, heart, etc. high-speed blood flow imaging. [0004] Therefore, how to ensure the frame rate of...
