Ultrasonic wave scanning method and device

Abstract

The invention provides an ultrasonic wave scanning method which comprises the following steps that ultrasonic wave scanning is carried out at a first scanning line of a plurality of scanning lines, and the multiple scanning lines are sequentially arranged in a row in space; and a second scanning line which is not scanned is selected from the multiple scanning lines, and ultrasonic wave scanning iscarried out at the second scanning line, wherein the second scanning line and the first scanning line are not adjacent in space. The second scanning line and the first scanning line are not adjacentin space, so that scanning carried out at the second scanning line is not interfered by ultrasonic wave energy scanning at the first scanning line, and the scanning time at the first scanning line does not need to be prolonged. Therefore, according to the ultrasonic wave scanning method, the frame frequency is not reduced, and the interference of ultrasonic waves can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic scanning, in particular to an ultrasonic scanning method and device. Background technique [0002] When using an ultrasonic scanning device to scan an object to be scanned (for example, human tissue, etc.), it is usually necessary to scan at different and spatially adjacent positions, that is, to form several non-repetitive scanning lines. In the prior art, the ultrasonic scanning method is usually a step-by-line scan, the specific process is as follows: figure 1 As shown, a focused ultrasonic beam is emitted at a scanning line and at least one signal line is received from this scanning line, and then the above operation is continued at the next adjacent scanning line until all scanning lines are scanned. Check the lines, and then process the received signal lines to generate a complete frame of ultrasonic scanning images, and usually these scanning lines are usually arranged in sequence in sp...

Problems solved by technology

[0003] In the existing step-by-line scanning method, the current scanning line and the next scanning line are spatially adjacent, and it is possible to use the same probe primitive to transmit and receive ultrasonic waves, understandably What’s more, within the interval T of two adjacent scans, the ultrasonic energy is difficult to completely attenuate, so that the residual ultrasonic energy in this scan may cause interference to the ultrasonic signal of the next scan, affecting the signal-to-noise In order to eliminate this interference, it is usually necessary to extend the scanning time T of each scan, so that the ultrasonic energy of each scan can be fully attenuated, and the impact on the next scan can be minimized, but the extension of the scan time means lower frame rate
