Abstract

본 발명은 체강을 형성하는 면에 조사하기 위한 X-선소오스(10)에 관한 것이다. 이소오스는 하우징(12), 기다란관상 프로우브(14), 타킷트조립체(26)와 팽창형 기낭(410)으로 구성된다. 하우징(12)에는 전자빔소오스(22)가 내장되어 있으며 빔진로를 따라 전자빔을 발생하기 위한 요소(23)를 포함한다. 관상프로우브(14)는 빔진로의 둘레에서 하우징(12)으로부터 중심축선을 따라 연장된다. 타킷트조립체(26)는 이에 투사되는 전자에 응답하여 X-선을 방출하는 타킷트요소(26A)(26B)를 포함한다. 프로우브팁조립체와 이에 결합된 제어전자장치는 빔빈로내에 타킷트요소를 배치시키시 위한 요소를 포함하고 X-선이 투과할 수 있게 되어 있다. 말단부에 고정된 기낭(410)은 체강을 확장시키도록 팽창되어 체강을 형성하는 면에 균일한 방사선의 조사가 이루어질 수 있도록 팽창가능하게 되어 있다.
