Useful information can be obtained by deprojection of the two-dimensional images of extended objects such as planetary nebulae or supernova remnants. Three-dimensional distributions (assumed to be axially symmetric) of emissivity, electron number density and temperature might be derived from the deprojected structures. As a test, we follow the iterative algorithm of Leahy & Volk (1994) to project the images of several PNe taken at different wavelengths. This method can also be applied to the images of supernova remnants and galaxy clusters.
