摘要： A system and method for MR imaging with coil sensitivity or calibration data acquisition for reducing wrapping or aliasing artifacts is disclosed. Low resolution MR data representative of coil sensitivity of a coil arrangement within an FOV is acquired prior to application of an imaging data acquisition scan and is used to reduce wrapping or aliasing artifacts in a reconstructed image.

摘要： A method and apparatus are disclosed for deriving an enhanced sensitivity matrix for describing coil sensitivity in a magnetic resonance imaging system. The enhanced sensitivity matrix provides sensitivity information for pixels near the edge of the imaged object such that pixels near the edge for which there was no sensitivity information are associated with a derived sensitivity. Likewise pixels near the edge for which there is measured sensitivity information are instead associated with a derived sensitivity to offset deficient sensitivity measurements near the edge of the object.

摘要： A method for reconstructing an image of an object includes unwrapping a reduced field of view image, and estimating edge boundaries using the unwrapped reduced field of view image. The estimated edge boundaries are used to calculate the number of aliasing replicates in the reduced field of view image. The number of aliasing replicates is used to unwrap the reduced field of view image.

摘要： An assembly of RF coils for bilateral imaging of a first and a second breast of the same person is disclosed. The assembly includes a first pair of coils having a first coil juxtaposed and underlapping a second coil, thereby defining juxtaposed edges of the first and second coils, and a second pair of coils having a third coil juxtaposed and underlapping a fourth coil, thereby defining juxtaposed edges of the third and fourth coils. The first coil has a first opening for receiving the first breast, the second coil has a second opening for receiving the second breast, the third coil substantially opposes the first coil, defining therebetween a first region for receiving the first breast, and the fourth coil substantially opposes the second coil, defining therebetween a second region for receiving the second breast.

摘要： An imaging method for an MRI system includes identifying a low signal region within a scanning volume. An overlap calculation of the scanning volume is generated. The low signal region is substantially eliminated from the overlap calculation thereby generating an adjusted overlap structure. A SENSE calculation is generated in response to the adjusted overlap structure.
