A variety of medical image reconstruction methods are very relevant to cancer research and diagnosis. Prime examples are: [Positron Emission Tomography (PET)][1], [CT][2], [MRI][3], etc.; In particular, all of these famous and successful technologies depend on solutions to inverse problems where one must reconstruct an image from a set of noisy measurements.
