The first stage: before in the 1970s, the tube of the x ray could be developed from fixed anode to rotate anode, from medium speed development to high speed, improved filament materials, made the tube heat capacity of x ray more and more big, the volume is more and more small, the technology is mature. High voltage generator control mode for development by mechanical vacuum tube control into transistor in control. Imaging to increase a film feeling screen mode, the same experience too slow, middle and high speed development process, perspective and photography dose is becoming more and more little. In this stage, the characteristics can be summarized as industrial frequency 50/60 Hz, increases the feeling screen a film.
The second stage:in the 20 years of 70-90s. Firstly, the appearance of X-ray image intensifier makes X-ray TV system to become a reality. Secondly, the development of the modern electronic computer technology, let people can store and handle images.The appearance of the DSA technologies make the frequency of high voltage generator develop from 50/60 Hz to 10 kHz.With the improvement of frequency, the volume of high voltage generator is reduced dramatically and make the pulse exposure as a reality. This phase can be summarized as DSA, high frequency silicon controlled.
The third stage: from90 s to the present day and the stage is the most rapid development of X-ray machines. Because of the applications of high power high frequency power module , such as IG-BT, IPM, GTR and high power CMOS module makes high voltage generator th frequency of up to 20-100 kHz, into the silent era. Image collection, appear l 249 line high TV system, air ionization chamber detector array detector array is more silk, semiconductor photosensitive detector array, after four ways of abandoned the traditional increase feeling screen-film combination, completed the direct digital photography. And along with the more and more quick processing of computer and the processing technology of computer image is mature, real-time DSA to become a reality. This period can be summarized as silent digital age.
With the development of science and technology in medical device field , authoritative medical X-ray machine manufacturers Perlong Medical also keep the step with The Times. Perlong Medical invests a lot of money each year for product development and upgrade and has the ability to the rapid market. At the beginning of establishment, Perlong Medical formed the leading high frequency power laboratory, develop the high frequency high-pressure X-ray generator and high frequency inverter power supply with completely independent intellectual property rights.Perlong Medical uses the advantages of powerful technology,developed many series and various models of X-ray machines, including high frequency mobile X-ray machines, the high frequency mobile surgery X-ray machine (c-arm, C arm X-ray machine), the High Frequency Remote-Control Fluoroscopic Equipment, high frequency radiography machine, high frequency digital radiography system (DR) and high frequency digital mobile X-ray machines , the 7000 series and other high-end products. Every year nearly 200 million total sales, in more than 60 countries have sales network and installed, the global 10000 machines in use!

In the process of development, Perlong Medical also don't forget to reward the society. In the first half of 2003 "against SARS war", in 2008 the wenchuan earthquake, 09 armour flow, 10 years for the society in yushu earthquake made due contributions, received users support, encourage and praise. We will with vigorous figure, strides forward, strive to become a world class medical equipment suppliers.
