Corrected magnetic resonance imaging using coil sensitivities

Abstract: The invention provides for a medical apparatus (300, 400) for generating a corrected magnetic resonance image (326, 502, 600, 700). The medical apparatus comprises a processor (308) for executing instructions, wherein execution of the instructions causes the processor to: receive (100) a set of N magnetic resonance images (320), wherein each of the set of N magnetic resonance images corresponds to one of N coil elements (426) of a magnetic resonance imaging coil (424); receive (102) a set of coil sensitivities (322) for each of the N coil elements; determine (104) for each of the N coil elements a coil sensitivity calibration (324) for each of the pixels; calculate (106) a value for each pixel of the corrected magnetic resonance image by dividing a first summation comprising the value of the pixel in each of the set of N magnetic resonance images by a second summation comprising the coil sensitivity calibration for the pixel in each of the set of coil sensitivities, wherein the first summation and the second summation are real valued.
