Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples.

[0027] Traditional beamforming requires an analog-to-digital converter (ADC) with a higher sampling rate to collect echo data of all channels. Generally, the sampling rate of the ADC is above 40MHz, and the number of channels is 32, 48, 64, 128, and each channel contains the information of all sampling points in depth. Such a large amount of data cannot be transmitted to the processor in real time through the existing hardware transmission interface, such as the central processing unit (central processing unit) , referred to as: CPU) to perform beamforming. Therefore, mainstream ul...

Abstract

Embodiments of the present invention provide a beam forming method and device. The method is applied to medical ultrasonic equipment, and the medical ultrasonic equipment includes a hardware programmable logic device and a processor. The method includes: a hardware programmable logic device acquires a signal to be processed, and the signal to be processed is a signal obtained by medical ultrasound equipment after preprocessing the received echo signal; the hardware programmable logic device performs signal sparse processing on the signal to be processed, and The processed data is transmitted to the processor; the processor performs interpolation processing on the received data, and performs beamforming on the interpolated data. The embodiments of the present invention can implement beamforming simply, conveniently, and with high precision.

Description

technical field [0001] Embodiments of the present invention relate to medical ultrasonic diagnostic technology, and in particular to a beam forming method and device. Background technique [0002] In medical ultrasonic diagnostic technology, the most important part is beamforming, and the key of beamforming is the delay calculation of data of different channels at different depths. Since the data intervals at different depths are very small, on the order of tens of microns, this leads to a large amount of data, which cannot be transmitted to the processor in real time on the existing hardware transmission interface for beamforming, so , mainstream ultrasound equipment manufacturers use hardware programmable logic devices for beamforming. [0003] However, beamforming using hardware programmable logic is more complicated, involving logic such as clocks, and it is difficult to deploy. Therefore, there is an urgent need for a simple, convenient and high-precision beamforming ...
