METHOD AND SYSTEM FOR CONSTRAINED RECONSTRUCTION APPLIED TO MAGNETIC RESONANCE TEMPERATURE MAPPING
First Claim
1. A system for performing image reconstruction of undersampled image data, the system comprising:
- a processor; and
a computer-readable medium operably coupled to the processor, the computer-readable medium comprising instructions that, upon execution by the processor, perform operations comprisingreceive imaging data of an image area, wherein the imaging data is thermal magnetic resonance imaging data in k-space generated at less than the Nyquist rate;
minimize a cost function based on an image estimate and the received imaging data; and
define an image of the image area based on the minimized cost function.

Abstract
A method, system, and computer-readable medium are provided which perform reconstruction of an image from undersampled k-space data. Imaging data of an image area is received. The imaging data is thermal magnetic resonance imaging data in k-space generated at less than the Nyquist rate. A cost function is minimized based on an image estimate and the received imaging data. An image of the image area is defined based on the minimized cost function. The received imaging data may include current k-space data and a summation of k-space data from previous time frames. Additionally, the image may be defined before imaging data is received for a next timeframe.
