Digital Subtraction Technique for Intravenous X-ray Image System

컴퓨터 영상처리 방식을 이용한 정맥내 혈관 조영술 시스템 개발

The objective of this research is to develop the hardware and software systenls of the digital intravenous angiographic system. The system will be used in clinical diagnosis of cardiovascular and cerebrovascular diseases. By utilizing computer image processing technique and digital subtraction method, the system can decrease the patient's harzard and expenses in performing intravenous angiography, as compared with conventional angiograms of the arterial injection.
