Patent ID: 7197353

Claim:
A method for producing a prescribed image of an object having a field of view D with a magnetic resonance imaging (MRI) system, the steps comprising: A) performing a pulse sequence with the MRI system to acquire calibration data with each of N local coils positioned near the object; B) performing a prescribed imaging pulse sequence with the MRI system to acquire image data with each of the N local coils; C) reconstructing calibration images with the calibration data; D) acquiring a calibration object image with the MRI system which depicts the object boundary disposed outside the field of view of the prescribed image; E) calculate a coil sensitivity image for each local coil using the calibration images; F) calculating an aliasing replicate number A for each pixel location in the prescribed image using the field of view D and the location of the object boundary; G) forming a sensitivity matrix S from the coil sensitivity images and the calculated aliasing replicate numbers A; H) reconstructing images I from the image data acquired in step b); and I) producing the prescribed image by calculating a proton distribution image M using the sensitivity matrix S and the images I.
