Zusammenfassung: | PROBLEM TO BE SOLVED: To realize optimum image quality when collecting magnetic resonance imaging data by a sensitivity encoding technique. SOLUTION: In this improved method, an MR image wherein an image pickup area is reduced is collected by the sensitivity encoding method. The number of aliasing replicates generated by surrounding an object boundary 229 is calculated to each image pixel location (254), and an aliasing artifact is optimally suppressed without reducing an image SNR. When calculating the number of the aliasing turnups, a calibration target image showing the test subject boundary 229 disposed outside the image pickup area of the magnetic resonance image is collected (202), and the number of the aliasing replicates is calculated in each the pixel inside the magnetic resonance image by use of a size and a position of the object boundary 229 coinciding with the pixel location and a phase encoding axis direction. |
