Correlation-weighted 23Na magnetic resonance fingerprinting in the brain
Lauren F. O'Donnell, Gonzalo G. Rodriguez, Gregory Lemberskiy +4
We developed a new sodium magnetic resonance fingerprinting ( MRF) method for the simultaneous mapping of , , $\…
Analysis of blurring due to short T2 decay at different resolutions in 23Na MRI
Olga Dergachyova, Zidan Yu, Shota Hodono +2
The nuclear magnetic resonance signal from sodium (23Na) nuclei demonstrates a fast bi-exponential T2 decay in biological tissues (T2,short = 0.5-5 ms and T2,long = 10-30 ms). Henc…
Analyzing Before Solving: Which Parameters Influence Low-Level Surgical Activity Recognition
Olga Dergachyova, Xavier Morandi, Pierre Jannin
Automatic low-level surgical activity recognition is today well-known technical bottleneck for smart and situation-aware assistance for the operating room of the future. Our study…
Knowledge transfer for surgical activity prediction
Olga Dergachyova, Xavier Morandi, Pierre Jannin
Lack of training data hinders automatic recognition and prediction of surgical activities necessary for situation-aware operating rooms. We propose using knowledge transfer to comp…
