Compressed Sensing for Rapid MRI: Need for Speed
MRI is a fascinating imaging technology used to visualize the internal structures of the body. However, acquisition speed still remains a challenge especially for patients who are anxious, can’t keep still or have limited breath hold capacity. These challenges can be solved with Compressed Sensing (CS) which helps us in decreasing the acquisition times without sacrificing image quality.
Conventionally, the compression of images is performed after the acquisition of the entire image. This is done to reduce data storage and facilitate transfer of such data. The idea behind CS is to compress and acquire only the most important coefficients of the signal during the acquisition.
