Problems solved by technology

[0002] In the existing field of puncture ultrasound imaging using a linear array probe, in order to obtain a puncture image that can clearly display the puncture needle, it is necessary to make the emission line of the probe perpendicular to the angle of the puncture needle. However, in the actual operation process, since the linear array probe is usually not When operating with the puncture frame, the angle between the emission line and the puncture needle often needs to be adjusted manually
[0003] The disadvantage of the prior art is that the deflection angle is not easy to determine without using the puncture frame because the emission angle of the emission line often needs to be manually adjusted during the adjustment process.

Embodiment 1

[0031] Such as figure 1 As shown, the method for automatically adjusting the angle of the probe emission line in the puncture includes the following steps:

[0032] S101, preliminarily adjusting the scanning line emission angle of the probe, emitting and acquiring puncture echo data.

[0033] By manually adjusting the deflection angle of the scanning line of the probe, the preliminary puncture echo data can be obtained. Theoretically, when the scanning line emission angle of the probe is at an optimized angle perpendicular to or close to the perpendicular (between 85-95 degrees) to the puncture needle, the display of the puncture needle is most obvious.

[0034] When using a linear array probe for scanning, usually the puncture needle and the linear array probe are not used in conjunction with the puncture frame, and manual adjustment is required. Usually, manual adjustment is difficult to accurately obtain the required optimal angle. Therefore, the display of the puncture n...

Abstract

The invention provides an automatic adjusting method for an emission line angle of a puncture needle probe. The method comprises the following steps: primarily adjusting a scanning line emission angle of the probe; emitting and obtaining puncture echo data; carrying out needle body identification on the puncture echo data, and calculating an inclined angle of a needle body; calculating an optimal scanning line emission angle of the probe according to the inclined angle of the identified needle body; and adjusting the scanning line emission angle according to the calculated optimal scanning line emission angle condition. The invention further provides corresponding device and system. By the aid of the method, the scanning line emission angle can be automatically adjusted according to the position of a puncture needle.
