초록

컴퓨터단층촬영(CT) 검사의 정맥주사(IV)시 조영제의 혈관외유출은 조직손상을 유발할 수 있다. Bolus tracking 시스템을 이용하여 조영제를 주입과정에서 발생하는 혈관외유출을 검출한다. 또한 조직손상을 방지하기 위하여 MPR 및 VR 영상을 이용하여 혈관외유출을 검출하였다. 조영제의 혈관외유출을 검출하기 위하여 16MDCT, 64MDCT를 사용하였다. 혈관외유출에 대한 3차원영상은 환자치료에 중요한 치료정보를 제공할 수 있다. 또한 조영제와 조직 간의 선예도를 개선하기 위해서 edge enhancement 영상처리기법을 적용하였고, 선예도 및 대조도가 개선되었다.

When injecting intravenously of CT inspection, the effusion of the contrast meium can induce the tissue damage with the blood vessel outside. We detect extravasation which is generated in the course where we inject the contrast medium into the blood vessel. And we use the bolus tracking system for the detection of that. By using MPR and VR images, moreover we detected the extravasation in order to prevent the tissue damage. In order to detect the effusion of the contrast medium, we used 16-MDCT and 64-MDCT. Three dimensional images about the outflow of the blood vessel can provide the treatment information which is important in the patient treatment. Moreover we applied the image processing technique in order to improve sharpness between contrast media and organization. And sharpness and contrast was improved.
