Abstract:
A magnetic resonance method for forming a fast dynamic image from a plurality of signals acquired by an array of multiple sensors, whereas prior to imaging a sensitivity map of each of the sensors is provided, at least two adjacent sensors record signals originating from the same imaging position, which signals are weighted with the sensitivity factor of the respective sensor at the respective imaging position, and the image intensity is calculated from the signals measured by the different sensors, and wherein the number of phase encoding steps is reduced with respect to the full set thereof, characterized in that k-space is segmented into regions of different acquisition, in the region of a first acquisition type there being acquired data of normal magnetic resonance imaging with a full set of phase encoding steps, or data of fast dynamic imaging with a number of phase encoding steps with a low reduction factor with respect to the full set thereof, for a first partial image whereas in the region of a second acquisition type data of fast dynamic imaging with a full reduction factor is acquired for a second partial image, the first and the second partial images forming the full image of the object to be imaged.
