Ultrasonic diagnostic device

Abstract

The invention discloses an ultrasonic diagnostic device comprising a base plate, an ultrasonic front end analog circuit, a digital processing circuit connected with the ultrasonic front end analog circuit and a power supply module for providing power supply for the ultrasonic front end analog circuit and the digital processing circuit, the ultrasonic front end analog circuit is of modular design,the digital processing circuit and the power supply module are positioned on one certain half edge of the base plate, and the ultrasonic front end analog circuit is positioned on the other half edge of the base plate. The ultrasonic diagnostic device of the invention adopts a modularization ultrasonic front end analog circuit, the assembling is convenient, the maintenance is easy, the subsequent performance upgrading of the ultrasonic diagnostic device is convenient, meanwhile the ultrasonic front end analog circuit is designed on the far ends of the power supply module and the digital processing circuit, so that the interferences from the power supply and the digital circuit can be prevented.

Description

【Technical field】 [0001] The invention relates to a portable ultrasonic diagnostic instrument. 【Background technique】 [0002] The hardware circuit of the portable ultrasonic diagnostic instrument is usually as follows figure 1 As shown, it includes the ultrasonic front-end analog circuit, the digital processing circuit (that is, the computer processing module) that processes and controls the echo signal of the ultrasonic front-end analog circuit, and the power supply module that provides power for the ultrasonic front-end analog circuit and the digital processing circuit. The ultrasonic front-end analog circuit is divided into two parts: transmitting and receiving. The transmitting generally adopts high voltage, while the receiving pursues low noise, so the performance requirements are very high. In the existing portable ultrasonic diagnostic instrument, the ultrasonic front-end analog circuit adopts ASIC to make a chip form, and adopts BGA package. Once the ASIC is made,...

Problems solved by technology

Once the ASIC is made, due to the high integration level, if it is found that the performance of individual channels affects the image quality after the whole machine is assembled, it is quite troublesome to disassemble and repair; and because the number of internal channels is fixed when the ASIC is designed, so in ultrasound It is very inflexible when the channel number requirements of the diagnostic instrument change
