Problems solved by technology

However, since the transmitting beam has a pulling effect on the receiving beams on both sides, the closer to the focal point, the more obvious the pulling effect and the more serious the distortion of the receiving beam
Therefore, it can be considered that the act

Abstract

The invention provides a multi-beam frequency compound imaging method and a system thereof. The method includes steps of (1) allocating scanning arrays comprising a scanning array which corresponds to transmission pulses Tx1-TxM of ultrasonic frequencies f1-fM, (2) transmitting ultrasonic pulses to detected tissues, (3) receiving echo signals from the detected tissues, wherein the emission of each transmission pulse corresponds to receiving of M echo signals in the same frequency, (4) and carrying out linear superposition on the M echo signals which are arranged on the same physical position and are in different ultrasonic frequencies f1-fM. Though adoption of the multi-beam receiving technology, the purposes of beam distortion correction and ultrasound compound of the multi-frequency signals are achieved at the same time, and the method is simple and easy to realize.

Description

technical field [0001] The invention relates to the technology in the field of ultrasonic diagnosis, in particular to a multi-beam frequency compound imaging method and system. Background technique [0002] Frequency compound imaging technology transmits fundamental wave signals with several frequencies, and collects ultrasonic scan lines with different frequency bandwidths at the same time, and finally forms an ultrasonic image. While ensuring the time resolution, the frequency compound imaging technology further enhances the spatial resolution of the ultrasound image and the uniformity of the overall image. [0003] In the prior art, there are two common frequency compound imaging techniques, one of which is: transmit an ultrasonic wave at a set physical scan line position, the ultrasonic wave has a certain frequency bandwidth, and then receive an ultrasonic echo at the same position Wave signal, and the received same echo signal is demodulated and filtered through differ...
