摘要 We analyze the characteristics of circular sampling and its applications in magnetic resonance imaging. The entire K space was sampled along a set of concentric circles by using only 50% of the pulses required by the standard line sampling technique (2DFT). The circular K space sampling provided better signal to noise ratio for equal acquisition time. The sampling configuration in the K space is identical to MR projection reconstruction.
