Working Principle

Ultrasonic Diagnosis Equipment is on the basis of different density and ultrasonic transmission speed, and different acoustic impedance (product of media density and velocity of sound), to regular electric impulse actuate piezoelectric wafer (transducer), ultrasonic at some frequency is produced, injecting the ultrasonic (sound wave) into human body, reflection echo will be produced via different viscera's interface, then the reflection echo can be absorbed by the transducer injecting such ultrasonic, when the transducer will convert the reflection echo (sound wave) to electric impulse, which after enlargement, examination and digital scanning, shall become standard video signal and display the intersection image of the organ on the screen of the monitor.

Characteristic
The high resolution Ultrasonic Diagnosis Equipment, controlled by computer and equipped with digital screening converter (DSC), is characterized by its clear image, stable performance and high resolution with adopting variable aperture, multi-segment dynamic focus, large dynamic band low-noise pre-amplifier, logarithmic compression, TGC control, dynamic filter, edge enhancement and frame-related technologies etc.

Four display format: B,B+B,4B,B+M,M; Image grey scale: 256 levels
Freezing, real time, selective enlargement, upwards/downwards and left/right turnover of the image can be realized
8 stage TGC adjustment.
18 types of body mark
Full-screen character annotation
Fixed character, real time clock and calendar

Built-in DSTN Processor, PAL-D and VGA video transmission, external screen monitor, colorful screen, video tape recorder, video image printer etc.
Movie replay function, uninterrupted replay or step forward/backward replay for 256 images can be realized.
Soft push keyboard and track ball or mouth are adopted, shortcut, convenient and flexible.
The equipment is an injection mold structure with non-power frequency converter, widely equipped with programmer and Surface Mount Technology (SMT), enjoying high degree of integration and outstanding performance.
The equipment is proved to be safe in use and simple in operation with clinic test.
