Mini B ultrasound machine based on high-sensitivity ultrasonic probe

Abstract

The invention discloses a mini B ultrasound machine based on a high-sensitivity ultrasonic probe. The mini B ultrasound machine comprises a B ultrasound host and the high-sensitivity ultrasonic probe. The B ultrasound host comprises a master control unit, an input module, a display module, a power supply module, a pulse amplifier, a reception amplification circuit, a synthesis circuit and an analog / digital converter. The first output end of the master control unit is connected with the input end of the ultrasonic probe through the pulse amplifier. The second output end of the master control unit is connected with the input end of the display module. The output end of the ultrasonic probe sequentially passes through the reception amplification circuit, the synthesis circuit and the analog / digital converter and is then connected with the first input end of the master control unit. The output end of the power supply module is connected with the second input end of the master control unit. The output end of the input module is connected with the third input end of the master control unit. The mini B ultrasound machine is compact in structure, external hardware circuits are simple, the design complexity and the hardware debugging difficulty are low, high precision is achieved, and the mini B ultrasound machine can be widely applied to the industry of mini B ultrasound machines.

Description

technical field [0001] The invention relates to the field of B-ultrasound instruments, in particular to a mini B-ultrasound machine based on a high-sensitivity ultrasonic probe. Background technique [0002] B-ultrasound machine is an imaging discipline that uses the physical characteristics of ultrasound for diagnosis and treatment, called ultrasound medicine. It has a wide range of clinical applications and has become an indispensable diagnostic method in modern clinical medicine. At present, in addition to conventional medical places, there is also a high demand for B-ultrasound machines in mobile medical places such as field and first aid. In order to meet the application requirements of these places, B-ultrasound machines are developing towards miniaturization. Now on the market, the main molding products of the mini B-ultrasound machine are produced by Siemens and GE. Both companies use phased probe technology to realize the miniaturization of the probe. However, due ...

Problems solved by technology

Now on the market, the main molding products of the mini B-ultrasound machine are produced by Siemens and GE. Both companies use phased probe technology to realize the miniaturization of the probe. However, due to the inherent weakness of the phased array probe, the The detection sensitivity, depth and clarity of the B-ultrasound machine are greatly reduced. Compared with the traditional electronic convex-array probe B-ultrasound machine, there is a big gap, which leads to the inability of the mini-B-ultrasound to achieve accurate detection, which affects its popularization and application.
