Abstract

Embodiments of the invention provide an ultrasonic signal treatment method and apparatus. The ultrasound signal treatment method comprises the following steps: performing iterating on a first iteration variable A<m>(n) and a second iteration variable a<m>(n) according to a size relationship between an initialized first iteration variable A<m>(0) and an initialized first intermediate variable B<m>(0), determining a delay time k<m>(n) of an echo signal of an ultrasonic signal emitted by an array element m to different detection distances, performing interpolating on the first iteration variableA<m>(n), and performing correcting on a delay time k<m>(n+1) respectively according to size relationships between interpolation variables shown in the specification and a first intermediate variable B<m>(n). The embodiments can realize reduction of a calculation amount required for delay calculation in a wave beam synthesis process, can improve an accuracy value of the delay calculation, and improves wave beam synthesis quality.

Description

technical field [0001] Embodiments of the present invention relate to signal processing technologies, and in particular, to a method and device for processing ultrasonic signals. Background technique [0002] With the continuous development of science and technology, ultrasound systems are more and more widely used in medicine. The most important part is beamforming, and the key to beamforming is the delay calculation for different array elements at different detection distances. [0003] Multiple array elements of the ultrasonic probe array emit detection sound waves. Due to the different positions of different array elements relative to the same tissue point, the path length of the infrasound wave reaching the tissue is different, and the reflection of the sound wave by different tissues is also different, and finally the sound wave is reflected back , the time to reach the focal point is not the same, different acoustic beams are superimposed to form a focal point, and t...
