Inverse problems in medical imaging are in their most general form ill-posed.
They literally have no solution. If, however, in advance we have additional
structural information or supply missing information, then we may be able
to determine specific features about what we wish to image with a satisfac-
tory resolution and accuracy. One such type of information can be that the
imaging problem is to find unknown small anomalies with significantly differ-
ent parameters from those of the surrounding medium. These anomalies may
represent potential tumors at early stage.
