Abstract
The subject invention pertains to a method and apparatus for producing sensitivity maps with respect to medical imaging. The subject invention relates to a method for applying an inpainting model to correct images in parallel imaging. Some images, such as coil sensitivity maps and intensity correction maps, have no signal at some places and may have noise. Advantageously, the subject invention allows an accurate method to fill in holes in sensitivity maps, where holes can arise when, for example, the pixel intensity magnitudes for two images being used to create the sensitivity map are zero. A specific embodiment of the subject invention can accomplish de-noise, interpolation, and extrapolation simultaneously for these types of maps such that the local texture can be carefully protected.
