Abstract:
An apparatus for detection of radiation comprising:at least a first collimator arranged to transmit radiation, emitted from a radiation source, through at least a first slit in a Z-direction and prevent radiation in said Z-direction apart from through said at least first slit, at least a first array of at least two radiation detecting elements, each of said radiation detecting elements having a width &agr; in an X-direction, where said X-direction is the direction of said array of radiation detecting elements, each of said radiation detecting elements having a length &bgr; in a Y-direction, said at least first slit, for letting through radiation in the Z-direction, having a length in said second X-direction which is at least as long as said array of radiation detecting elements, said at least first slit having a length in said Y-direction which is substantially shorter than said length &bgr; of said radiation detecting elements, and displacement means arranged to move said collimator and/or said array of radiation detecting elements.
