Ultrasound diagnosis instrument mainly refers to ultrasound diagnosis device in medical image system. Due to its price is cheaper than Computed Tomography and MRI and has the character of no wound and obtain organization image in the body in time. So it is more and more wide in clinical application and total sales growth will exceed medical-x-ray machine equipments. International market sales were twenty billion dollars in 1994 and they were 28 billion dollars in 2000.

Recently, International ultrasound diagnosis instruments have a good development with computer, microelectronics and image rapid development. The main ultrasound diagnosis instrument manufacturers in the world has launched out newest machine which is behalf of the advanced level of ownself. It promotes continuous development of world ultrasound diagnosis instrument technology level.

There are several sides of international ultrasound diagnosis instruments getting significant development in recent years as the following:

First, Ultrasonic transducer

Second, Digital ultrasonic diagnosis device has become a trend

Recently, due to microelectronics technology development, high speed and high accuracy A/D and ASIC devices invented, medical ultrasound diagnostic instrument digital has become a trend. Since ALT company invented the first digital B ultrasound in the 90 s, the main several medical ultrasound diagnosis manufacturers in the world have launched out digital colour ultraound.

There are several new imaging way which main ultrasound diagnosis instrument manufacturers launched out.

 Firstly, Doppler energy imaging

Secondly, TissueDopplerimaging

Thirdly, second harmonics and acoustic imaging

Fourth, dimensional imaging

Fifth, Remote and networking ultrasound image workstation

At present, International DICOM3.0 standards was established and there were companies launching out the product of ultrasound diagnosis instrument and ultrasonic image workstation integration to market. It will become development trend of high-grade model.
