Title
(JA) X線発生管、X線発生装置およびX線撮像装置
Abstract
(JA)

X線発生管は、第1開口端および第2開口端を有する絶縁管と、電子放出源を有し、前記絶縁管の前記第1開口端を閉塞するように配置された陰極と、前記電子放出源からの電子が衝突することによってX線を発生するターゲットを有し、前記絶縁管の前記第2開口端を閉塞するように配置された陽極と、前記絶縁管の内側空間において前記陽極から延びた管状導電部材とを含む。前記絶縁管は、前記第1開口端から離隔しかつ前記第2開口端から離隔した位置に管状リブを含む。前記管状リブは、前記管状導電部材における前記陰極の側の端部から見て放射方向に配置される。
