Abstract:
1. A method of generating a magnetic resonance image of an object in cyclic motion, comprising the steps of: (a) defining a desired acceptance window corresponding to an extent of motion over which image data may be combined; (b) defining a series of position bands, together covering the total range of expected motion, to enable object positions within that range to be assigned to one of said bands, the range of motion corresponding to at least one of said bands being less than or equal to the acceptance window; (c) selecting a required image resolution, thus defining the number of ky lines to be acquired; (d) acquiring ky data and object position data according to a first phase of data collection, comprising the steps of: (e) acquiring ky data and object position data according to a second phase of data collection, comprising the steps of:
