Abstract
A computed tomography (CT) scanning system including a source operable to emit a cone beam of radiation toward an object, a detector operable to detect radiation emitted by the source and to produce detector values related to projections of an object attenuation, a turntable operable to rotate the object about a rotational axis, and a source mover operable to move the source so as to vary an angle between the cone beam and the rotational axis.
Claims9
A computed tomography (CT) scanning system comprising:
- a source operable to emit a cone beam of radiation toward an object;
- a detector operable to detect radiation emitted by said source and to produce detector values related to projections of an object attenuation;
- a turntable operable to rotate the object about a rotational axis;
- and
- a source mover operable to move said source so as to vary an angle between said cone beam and said rotational axis, said source mover being decoupled from said detector and being operable to vary a position of said source with respect to said detector.
