초록
이 연구는 디지털 유방확대촬영술에서 방사선 피폭을 감소시키며 영상의 질을 유지하기 위한 최적의 촬영조건을 알아보았다. 자동노출방식의 평균유선선량이 수동노출방식에 비해 높은 것으로 나타났다. 자동노출방식은 그리드(grid) 사용 여부에 따라 평균유선선량과 화질평가에 차이가 많았으나, 수동노출방식은 팬텀영상평가 점수에서만 차이가 있었다. 그러나 air gap technique을 사용할 경우 모든 노출방식에서 신호대잡음비의 증가가 뚜렷하게 나타났다. 따라서 유방확대촬영 시 air gap technique을 사용한다면 환자의 평균유선선량을 감소시키고 신호대잡음비를 높여 양질의 화질을 유지할 수 있을 것이다.
Abstract
The purpose of this study was investigated optimal exposure condition in digital magnification mammography to decrease radiation dose and increase image quality of the examinee. Auto mode, the average glandular dose is higher than the manual mode. Average glandular dose and image quality were many differences on between grid and air gap technique in auto mode. However, Average glandular dose and signal-to-noise ratio were not different on between grid and air gap technique in manual mode. The signal-to-noise ratio was increased when using the air-gap technique in both mode. According to result, air gap technique may reduce average glandular dose and increase signal-to-noise ratio in digital magnification mammography.
