New class of fractals could make for speedy whole-body MRI

An Australian researcher has said it could be possible to speed up full-body MRI by four times while controlling costs and maintaining quality—all thanks to the discovery of a new class of fractals. Shekhar Chandra, PhD, with the University of Queensland, believes “Chaotic Sensing,” an approach to sparse imaging using fractals, could help MRI machines to quickly identify necessary imaging information while discarding redundant data.

MRI helps build personalized 3D simulations of heart irregularities

Scientists hope personalized data from patients experiencing irregular heartbeats will help improve accuracy in heart ablation procedures. The 3D simulations of 21 patients allow physicians to locate arrhythmia by “poking” the simulated heart with small electrical signals in various locations.
