An iterative method of reconstructing degraded images is developed from con
sideration of a mixed-noise imaging situation. Both photon noise in the ima
ge itself and postdetection Gaussian noise are combined by use of the stand
ard maximum-likelihood method to produce a mixed-expectation reconstruction
technique that demonstrates good performance in the presence of both noise
sources. The new algorithm is evaluated through computer simulations. (C)
