Operatively adaptive ultrasound imaging system

Abstract

An ultrasound imaging system is disclosed, comprising: an ultrasound probe (1) comprising transducers (10), a digital acquisition board (2) comprising : electronic circuits (21, 22, 23) adapted to control the transducers to emit ultrasound waves and to convert signals sensed by transducers into digital data, and a real-time sequencer (20) adapted to control the electronic circuits to drive the emission and reception of ultrasound signals, based on working parameters and sequence parameters, and a computer (3) connected to the digital acquisition board and comprising a computer's memory (34), the parameters being stored in the computer's memory, the digital acquisition board further comprises a DMA controller (24, 25) adapted to access the computer's memory in reading and writing by implementation of DMA protocols, and the sequencer is adapted to send requests to the DMA controller to recover said parameters from the computer's memory in real time.

Description

technical field [0001] The invention relates to an ultrasonic imaging system, a digital acquisition board part of the ultrasonic imaging system and an ultrasonic imaging method. Background technique [0002] refer to figure 1 , a known ultrasound imaging system comprising: [0003] - an ultrasonic probe 1 comprising a plurality of transducers for transmitting and receiving ultrasonic waves in a medium, the received ultrasonic waves being sensed by said transducers, [0004] - a digital acquisition board 2 comprising an electronic circuit adapted to direct the transducer to emit ultrasonic waves and to convert said sensed received ultrasonic waves into input data, and [0005] - A computer 3 which receives said input data over a data channel and processes these to provide an image representing an area of ​​said medium, said process being called beamforming. [0006] According to this known imaging system, the electronic circuit of the digital acquisition board 2 comprises ...

AI Technical Summary

Problems solved by technology

[0024] In addition, since the user only has access to the computer 3 and cannot directly and transparently access the digital acquisition board 2, it is not easy to change parameters during real-time operation, such as switching from one imaging mode to another immediately or in real-time It is not easy to change the transport focus law seamlessly during operation
