The
visualization of structures in MRI highly depends on many user defined scan
parameters. The selection of them is always done heuristically and requires a
vast experience from the operator. We propose a methodology based on an
automatic optimization to find the MRI acquisition parameters that maximize
the visibility of a desired structure. The objective function of our
optimization is computed from Visibility Maps (VM) that are designed to
measure the visibility of structures according a perceptual criteria. The
method was tested on brain MRI experiments and the optimal parameters found
by our method are in excellent agreement with those found by experienced
radiologists.
