Abstract:
A system for constructing image slices through a selected object comprising:a. an identifiable fiducial reference located at a fixed position relative the selected object, to fiducial reference having a total number of degrees of freedom associated therewith greater or equal to the total number of degrees of freedom of the system;b. a source of radiation for irradiating the selected object and the fiducial reference;c. a recording medium for recording a projected image of the selected object and the fiducial reference; andd. an image synthesizer for analyzing parameters related to positions and sizes of the images detected upon said recording medium to produce image translation data, and for reconstructing a tomographic slice from said object images and said translation data;whereby the fiducial reference, the source of radiation, and the recording medium are moved arbitrarily relative to one another.
