Weak electric fields detectability in a noisy neural network.

Research RF Safe Research Library Jan 1, 2017

This modeling study examines how a noisy spiking neural network detects a weak applied electric field using an Izhikevich neuron framework with excitatory/inhibitory neurons and conduction delays. The authors report stochastic resonance driven by white noise that enhances detectability, and that this effect largely…

Liver lesion conspicuity during real-time MR-guided radiofrequency applicator placement using spoiled gradient echo and balanced steady-state free precession imaging.

Research RF Safe Research Library Jan 1, 2014

This retrospective study evaluated liver lesion conspicuity during real-time MR-guided radiofrequency applicator placement using spoiled GRE and balanced SSFP MRI sequences in a 1.5 T scanner. Lesion detectability categories and contrast-to-noise ratio (CNR) were compared for hepatocellular carcinoma and liver…
