Objective:Application of interventional radiology equipment, through the introduction and materials in clinic,to better grasp the method of interventional radiotherapy and interventional radiology treatment,reduce adverse events in clinical application. Methods: Various imaging devices such as DSA, CT, MRI etc, imaging within the body structure, the size of the lesion and its relationship with the surrounding tissue by these devices can be very good;and the development of medical devices that need not operation, can accurately reach the lesion site for treatment. Results:At present, the interventional radiology doctors has to catheters or devicesinterventionalvascular branches, the digestive tract and other specific parts, used in the treatment of disease. Conclusion:Interventional radiology is an emerging treatment method as the development of modern science and technology. Interventional also has some adverse events radiotherapy applications, will damage the doctor and the patient's health and the impact of clinical diagnosis and other accidents, so do the crime prevention work is very important, so as to carry out the interventional radiology treatment.

Objective By the modern manufacture regulation of original equipment manufacture(OEM),the quality of large scale X-ray equipment is ensured by means of assembling the purchased key components,such as high frequency and high voltage generators and X-TV systems,etc.Methods The technology of Programmable Logic Controller(PLC)was utilized to improve the reliability of X-ray examination table.Results The design of PLC-controlled X-ray examination table was used in the digital X-ray equipment yeas ago.The malfunction probability of mechanic parts was very low,whereas the electric circuit part was almost zero.Conclusion The practice of PLC improves the reliability and control level for X-ray equipment.

Objective To improve the image intensifying X-TV system by replacing the light-conduct camera with CCD camera for future usage.Methods The low luminous and high sensitive CCD camera was used in the X-ray auto exposure dose control.Results Through the practical improvement,the CCD X-TV system met the clinical requirements.Conclusion It is an effective way to replace the old light-conduct camera with CCD camera,and it also helpful for the alternative solutions for X-TV.

Objective To improve X-ray equipment for better medical treatment by digitally transform normal X-ray equipment.Methods Digital image workstation was equipped for digital photography so that ordinary X-ray equipment has the function of a digital X-ray equipment.Results The digital transformation enhance the clinical performance of X-ray equipment.Conclusion It has been proved that some ordinary X-ray equipment can be equipped with digital workstation.

Mineralized tissue regeneration is an important and challenging part of the field of tissue engineering and regeneration. At present, autograft harvest procedures may cause secondary trauma to patients, while bone scaffold materials lack osteogenic activity, resulting in a limited application. Loaded with osteogenic induction growth factor can improve the osteoinductive performance of bone graft, but the explosive release of growth factor may also cause side effects. In this study, we innovatively used platelet-rich fibrin (PRF)-modified bone scaffolds (Bio-Oss
