History of 25 years since 1984, we are exploring  developing method for digital radiography technology in China......

Year 1984, began to integrate computer image processing tech into radiography imaging

Year 1988, the first digital radiography software was developed in China

Year 1992, theory research of image processing has passed the technical results authentication by former National Mechanism Bureau

Year 1993, established the first enterprise in the field of digital radiographic imaging equipment professionally

Year 1995, digital radiography imaging equipment which replaced the original film one has been accepted by our country

Year 1997, steel tube X-ray imaging system has been extensively applied in big spiral tube factories to substitute for film imaging, been accepted by International Supervision Institution and has won great economic benefits.

Year 1998, proposed and established the national standard which is called "GB17925-1999 X-ray real time imaging inspection for cylinder weld", which has issued in Oct, 1999. That gives the sign of the beginning of X-ray real time imaging system being used in the pressure vessel field

Year 2001, achievement for development testing and application of panel detector

Year 2001, achieved development of digital X-ray imaging system with the core of scanning camera and digital dynamic image procesing, so that offers a good precondition to the castings inspection in productio- line

Year 2001, the first digital X-ray imaging system was designed, and was put into application in Jianghua Automobile Company, offers best solution for small workpiece X-ray inspection

Year 2002, attended the national standard establishment "GB/T 19293-2003 butt weld X-ray real time imaging system", and was put into application in April, 2003

Year 2002, as a head officer, Mr. Sun has successfully developed GW-500 and GW-200 X-ray inspection system with the core of CMOS camera in the field of long-distance pipeline inspection, being accepted with highly value by NDT experts all over the world after WCNDT (World Congress of Non Destructive Testing)

Year 2002, the first "X-ray scanning inspection system using in production-line" has been developed, having broken the limitation of traditional X-ray inspection system, having solved problem of complex workpiece in a large quantity, it can inspect more than 10000 pieces per day

Year 2003, projects about "digital CMOS radiography imaging research" and "X-ray imaging system for pipe weld inspection research" have been authenticated as "sophisticated domestically, advanced internationally"

Year 2003, the "boiler tube inspection system in production-line" invented adopts "double wall double shadow" technics developed by our own, helping the inspection sensitivity and resolution reach the best level. It acquires comprehensive acceptance from boiler factories

Year 2005, acquired national "Technical Inspection Development" award for individual

Year 2007, after reconstruction, RichGolden Company was established, acquiring 10 national patent authorization

Year 2008, have lukily been the leadership enterprise of the NDT standardization real time radiography imaging group authorized by National Development and Reform Commission

Year 2008, invented Multi-RT hierarchical real time imaging software
