Radial Streaking Artifact Reduction Using Phased Array Beamforming

Case ID:

This invention is a method and software for mitigating the streaking artifact in radial magnetic resonance imaging (MRI). After being tested on MRI scanners and compared to current coil based methods, this new method, known as B-STAR, utilizes phased array beamforming and reduces streak artifacts without any noticeable loss in signal levels.


When taking images of large areas of the human body, like the abdomen, obstruction will occur in a streaking artifact. This streaking artifact makes the image difficult to read and significantly lowers the quality, which can result in an incorrect diagnosis, inevitably slowing down the treatment and healing process for a patient. Therefore there is a need for a strategy that can mitigate the streaking artifacts in MRI.
