METHOD FOR MOTION ARTIFACT SUPPRESION BY NMR DATA COMBINATION

PURPOSE: To suppress a motion artifact by weighing NMR image data as the function of the deviation of related motion data and then combining each view of a plurality of sets of NMR image data. CONSTITUTION: A computer stores two sets of NMR data containing a two-dimensional array of image data 205 as well as the related linear array of displacement data obtained from a first scan, and similar data arrays 207 and 208 obtained from a second scan. Also, a smooth curve is established for calculating a deviation value from both displacement data, using the least square method. Then, deviations 209 and 210 from the curve are found, and image data 205 and 297 are respectively weighed, using the deviations 209 and 210 as functions, thereby obtaining combined image data 211 and preparing a two-dimensional display data array 212 for showing the intensity of each picture element of a display. As a result, the occurrence of a motion artifact can be lessened.
