A fundamental ultrasound machine offers the next areas: * Transducer probe - probe in which} sends and obtains the sound waves; * Central processing unit (CPU) or key handing part pc that performs almost all of the measurements and includes the energy power ; * Provides for itselves and the transducer probe

Trolley ultrasound diagnostic machine, which is more close to the one of conventional ultrasound series. Of which appears of floor-shape and is always placed in a dedicated ultrasound department room for a special use. Of most hosts which are on wheels, and it can push smoothly due to the large volume. However, under its heavyweight and an inconvenient moving in reality, such a trolley ultrasound diagnostic machine can be also use in hospital and other large spaces well.

First Three-dimensional ultrasound, a three-dimensional ultrasound belonging of one color Doppler ultrasound, three-dimensional ultrasound is a dynamic display. And the superiority of three-dimensional ultrasound including uterine artery, ovarian blood flow sensitivity, display rate; shorten the examination time, to obtain an accurate Doppler spectrum; without filling the bladder, not obese, abdominal scars, intestine inflatable interference; activities by means of the probe tip to find the site of pelvic organ tenderness determine whether pelvic adhesions.

The causing fluctuations in the human auditory organ is called the acoustic sound perception, the human ear's hearing threshold range, the vibration frequency of 16kHz-20kHz, exceeding the upper limit of human hearing threshold of sound waves, that is greater than 20kHz sound waves called ultrasound, referred to as ultrasound, clinical ultrasound frequency commonly used in 2-10MHz.

Sound waves are mechanical vibrations in an elastic medium spread, due to the different ways of vibration and transmission, it can be divided into many types. Of which the most important are longitudinal wave, shear wave, wave and so on. By shock waves in different ways it can be divided into continuous wave and pulsed wave. Medicine for diagnostic ultrasound is a longitudinal wave.
