Abstract
A method and an apparatus for reconstructing SPECT image capable of improving the SPECT image resolution. The apparatus includes: a detector, including a fan-beam collimator, for detecting gamma (.gamma.) rays emitted from a radio isotope injected into a biological body; a rotation unit for effecting relative rotation between the biological body and the detector about a center of rotation to thereby acquire projection data from a different direction; a first reconstructing unit for convoluting the projection data obtained from the detector, by a first convolution function, and for back-projecting the convoluted projection data to a specific region which lies in a sufficiently close vicinity of the detector; a second reconstructing unit for convoluting the projection data by a second convolution function, and for back-projecting the secondly convoluted projection data to another specific region; and display means for displaying thereon a distribution image reconstructed by the first and second reconstructing units.
