Current situation of the study work of radiation dose and health effect in interventional radiology

Interventional radiology is a new technique in medical diagnosis and therapy.Based on the new computer tech-nique and bioengineering material,it has gotten much progress.Though the patients can get a lot of benefits from this tech-nique,scientists have noticed that the latency radiation risk of the patients.In some interventional radiological procedures,skin or lens injuries of the patients may be induced in non-optimized interventional radiology.Therefore,the scientists of radiation protection put their attention on the problem of the patient protection in the world.
