Veterinary Portable Cow Ultrasound Scanner for Pregnancy Test
STT-51353A-600B
1. Basic 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 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.
