ABSTRACT:
Medical radiographic apparatus is described in which a source of a fan-shaped spread of X-radiation is arranged to project the radiation through a cross-sectional slice of a body under examination. Collimators are used to section up the radiation emergent from the body into finger-like beams which have traversed respective, substantially linear paths through said slice. The source is angularly moved around the body so as to project radiation through said slice from a plurality of directions relative thereto.
The collimators also perform the angular movement and means are provided to cause the said paths traversed by the beams at one time during the angular movement to interleave with the paths traversed by the beams at another time during the angular movement.
