Trolley Ultrasound System Diagnostic Equipment

Basic principle
The equipment is composed by the main unit(software version V1.0), monitor and probe. It is a high resolution diagnosis equipment, it's controlled by microcomputer and applied with DSC, DBF, RDA, DRA, DRF, DFS and frame correlation technologies etc. The image is clear and high resolution.
DIGITAL ULTRASOUND which electrical impulses arouse wafer (transducer) to produce certain frequency ultrasonic wave according to the different organs with different density and ultrasonic velocity, i.e., different acoustic impedance (the product of medium density and sound velocity),,and produce response signal through organs the response waves are absorbed by transducer, then transfer into electrical impulses, and become video signal after processed by detecting and digital scan, then show the sectional image of organs on screen.

1. Specification:
SH1000 , based on embedded LINUX system, is digital ultrasound diagnostic system. It adopts the technology of digital information processing, digital code, multi-focusing, consecutive & dynamic tracking etc and it's easy to upgrade the software online. Meanwhile, the digital structure makes it flexible to choose scanning mode and probes in the whole operation frequency.
