Description

X선 진단장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 피사체에 X선을 폭사(曝射)했을 때의 산란 X선이 발생하는 상태를 나타내는 설명도.
제2도는 산란 X선을 포함하는 X선의 강도와 검출기상의 위치와의 관계를 나타내는 특성도.
제3도는 산란 X선의 공공분포의 모양을 모식적으로 나타내는 설명도.

Claims (2)

  1. 피사체를 투과하는 X선을 검출하는 검출기에 의하여 출력되는 검출신호를 따라 화상을 표시하는 X선 진단장치에 있어서, X선 조사야 내에 X선을 부분적으로 차단하고, 또 X선 조사야내에 출입이 가능한 X선 차단수단과, 이 X선 차단수단을 X선 조사야내에 위치시켜서 피사체에 X선을 폭사해서 얻어지는 피사체투과 X선 정보를 따라 X선 조사야내의 산란 X선량을 산출하는 제1연산수단과, 이 제1연산수단의 출력데이터를 X선조사야내에 상기 X선 차단수단을 위치시키지 않고 피사체에 X선을 폭사해서 얻어지는 피사체투과 X선정보에서 감산하고, 직접 X선 성분에 의한 피사체투과 X선 정보를 출력 가능한 제2의 연산수단을 구비하는 것을 특징으로 하는 X선 진단장치.
  2. ※ 참고사항：최초출원 내용에 의하여 공개하는 것임.
