The subject invention pertains to a method for magnetic resonance imaging
(MRI) involving the acquisition of pseudo-polar K-space data and creation
of an MRI image from the pseudo-polar K-space data. In an embodiment, the
subject method can incorporate a scan scheme for acquiring pseudo-polar
K-space data and corresponding reconstruction technique. Advantageously,
the subject method can result in reduced motion artifact in dynamic MRI
with short acquisition time and short reconstruction time. In a specific
embodiment, the subject method can incorporate a reconstruction method
utilizing Fractional FFT in MRI. The subject method can allow the
acquisition of pseudo-polar K-space data. In a specific embodiment, the
acquisition of the pseudo-polar is accomplished by one shot. Other
acquisition techniques can also be utilized in accordance with the
subject invention. In an embodiment, the pseudo-polar K-space data can
lie at the origin of K-space and on N linearly growing concentric
squares, with N.ltoreq.2, where the distance between adjacent concentric
squares is the same as the distance from the origin to the innermost
square. The K-space data on the N concentric squares are equally spaced
from adjacent data points on the same square, including data points at
the corners of each square.
