Abstract
In a rapid auto-calibrated partially parallel reconstruction method, the unaliasing process is approached by convolution. The image combination is performed on a low-resolution image matrix before unaliasing, and the unaliasing process is effectively performed once for a single synthetic target coil instead of for each individual coil.
Claims26
A method implemented in a processing device for reconstruction of an image in a region of interest, the method comprising:
- (a) acquiring under-sampled raw image data from the region of interest into the processing device;
- (b) determining, in the processing device, weighting coefficients such that a sum of products of the weighting coefficients and the under-sampled raw image data will produce an unaliased full-field-of-view image of the region of interest;
- (c) multiplying, in the processing device, each of the weighting coefficients by a corresponding one of the under-sampled raw image data to produce a product;
- and
- (d) summing the products in the processing device to produce the unaliased full-field-of-view image of the region of interest.

A system for reconstruction of an image in a region of interest, the system comprising:
- an image acquisition component for acquiring under-sampled raw image data from the region of interest;
- a processing device, in communication with the image acquisition component to receive the under-sampled raw image data, for determining weighting coefficients such that a sum of products of the weighting coefficients and the under-sampled raw image data will produce an unaliased full-field-of-view image of the region of interest, multiplying each of the weighting coefficients by a corresponding one of the under-sampled raw image data to produce a product, and summing the products in the processing device to produce the unaliased full-field-of-view image of the region of interest;
- and
- an output device, in communication with the processing device to receive the unaliased full-field-of-view image, for outputting the image reconstructed by the processing device.
