COMPUTED TOMOGRAPHY SCANNER WITH LARGE GANTRY BORE

COMPUTED TOMOGRAPHY SCANNER WITH LARGE GANTRY BORE

A computed tomography scanner includes a rotating gantry ( 20 ) defining an examination region ( 16 ). A first radiation source ( 22 ) is disposed on the rotating gantry ( 20 ) and emits first radiation ( 32 ) into the examination region ( 16 ). A second radiation source ( 24 ) is disposed on the ro...

Zusammenfassung:A computed tomography scanner includes a rotating gantry ( 20 ) defining an examination region ( 16 ). A first radiation source ( 22 ) is disposed on the rotating gantry ( 20 ) and emits first radiation ( 32 ) into the examination region ( 16 ). A second radiation source ( 24 ) is disposed on the rotating gantry ( 20 ) and emits second radiation ( 36 ) into the examination region ( 16 ). The second radiation source ( 24 ) is angularly spaced around the gantry from the first radiation source ( 22 ). A first radiation detector ( 30, 30 ') receives the first radiation ( 32 ). A center of the first radiation detector ( 30, 30 ') is angularly spaced around the gantry from the first radiation source ( 22 ) by less than 180°. A second radiation detector ( 34 ) receives the second radiation ( 36 ). A center of the second radiation detector ( 34 ) is angularly spaced around the gantry from the second radiation source ( 24 ) by less than 180°.
