Abstract

The invention is suitable for the medical image treatment field, and provides an ultrasonic puncture needle image enhance method and device. The method comprises: generating an emission angle sequence according to a preset ultrasonic wave emission turning angle, the preset ultrasonic wave emission turning angle being set according to probe frequency attribute and imaging characteristics; generating image streams of different attribute characteristics according to the emission angle sequence; respectively performing corresponding treatment on the image streams according to different attribute characteristics of the image streams; and fusing image streams after treatment to obtain ultrasonic puncture needle enhanced images. According to the invention, a generated emission angle sequence can more accord with probe attributes without user intervention; operation steps are simplified; clearer and more accurate ultrasonic puncture needle images can be obtained.

Description

technical field [0001] The embodiments of the present invention belong to the field of medical image processing, and in particular relate to a method and device for enhancing an image of an ultrasonic puncture needle. Background technique [0002] The basis of ultrasound imaging is sound wave reflection, and the reflected energy forms an image through a series of post-processing. During the puncture process, the puncture needle or injection needle must penetrate into the patient's body at a certain angle, because when the normally emitted sound waves touch the needle surface at a vertical angle, energy is lost in the reflection and the carried needle signal is weakened. When the angle of penetration into the patient's body becomes larger and the depth gradually becomes deeper, the needle signal becomes very unstable or even disappears. If it is necessary to accurately analyze the ultrasound image of the patient itself, it is necessary to determine the needle signal in the ul...
