ABSTRACT:
Computerized tomographic apparatus is capable of producing representations which show, with high accuracy, the absorption coefficients, with respect to x-radiation, at various locations distributed over one or more selected cross-sectional slices of a patient's body. The evaluation of the absorption coefficients is effected by determining the absorption suffered by the radiation on traversing each of many substantially linear paths from a source of the radiation to a detector means, the paths traversing the body slice. The invention resides in compensating for changes in the energy spectrum of the radiation as projected through the body along different ones of said paths, which changes could otherwise impair the accuracy of said representations.
