3.4 Basic Principle
The device utilizes a 2D Mechanical sector scanning probe to provide ultrasonic scans of the
bladder and calculates the volume of the bladder through complicated computations.
Operating principle: 1. Transmits the pulse signal to the 2D probe. Launch the ultrasonic wave to
the human body via the transducer of the probe (such pulses can only acquire one signal of one plane,
meaning to produce a 2D image section it needs to send ultrasonic waves at least 96 or 128 times to
form one section.) The ultrasonic wave transmits, or scatters, a wave through the body, and sends the
received reflected signal to the DSC via the transducer, and proceeds with a serials of signal processing
methods: logarithms compression, detection, dynamic filter, edge enhancement, frame relevance, line
relevance, etc., to form one high-definition section image to display on the screen. Then it processes the
image to figure out the volume of the bladder.
