Latest Patents

Bragi Sveinsson's latest patents include a method for estimating T2 and a method for distortion-free magnetic resonance imaging near metallic implants. The first patent provides an estimated 3D Tmap for MRI using a Double-Echo Steady-State (DESS) sequence. This method involves acquiring signals Sand Sare to provide a Tmap for multiple slices of the volume. It also includes determining key parameters such as repetition time (TR), echo time (TE), and flip angle (α). The DESS scan incorporates a spoiler gradient to ignore echo pathways that have spent excessive time in the transverse plane.

The second patent addresses the challenge of slice-direction distortion in MRI. It describes a method for 3D imaging that corrects distortion by resolving positions using phase encoding. This technique involves exciting selective cross-sections with an RF pulse and applying a refocusing pulse to form a spin echo. The data is acquired with an under-sampling scheme, ensuring high-quality imaging even near metallic implants.
