Abstract:
A method of deconvolution filtering image data from an imaging system having a point spread function, the method comprising:obtaining image data generated by the imaging system, the image data representing convolution of the point spread function of the imaging system and an image of a source object that is known a priori;in the spatial-domain, filtering with an FIR filter said image data to provide filtered image data, said FIR filter having a plurality of coefficients;in the spatial-domain, comparing a synthesized representation of said source object and said filtered image data to generate an error function;adaptively adjusting said coefficients to determine a minimum of the error function;ending said adjusting of said coefficients to provide fixed coefficients;using said fixed coefficients to filter subsequent image data in a non-adaptive manner;wherein said FIR filter deconvolves said image data;said image data comprises three-dimensional image data and said FIR filter includes coefficients for each of said three dimensions; andsaid FIR filter is a one-dimensional statistical filter and said convolution is three dimensional.
