Position (general motion blur is a special case of it) dependent blurring can be applied to denisty improvement but problem is extremely ill posed. While deblurring you need to reduce noise amplification. Proper regularisation needs to be designed, probem becomes NxN linear equation where N is the number of grid points in density which might be a little bit large. However iterative method exists in inverse problems field.
