Pocket MRS was
designed to be a fast and helpful electronic reference and educational tool for
students, medical professionals, researchers and anybody else engaged in the
field of in vivo MRS.
Figure
1: Brain MRS - Adjustments. The simulated brain
spectrum for 3 T (A). The spectrum can be adjusted for echo time from 0 to 300
ms (B), line broadening (C) and noise (D). Screenshots from the iOS simulator.
Figure 2:
Brain MRS - Analysis. User can control echo time, line broadening and noise
levels in order to create a realistic spectrum (echo time = 20 ms, line
broadening = 5 Hz, noise = 80) (A). The spectrum can be analyzed by visualizing
a metabolite, e.g. background signal of macromolecules (B), or group of
metabolites, e.g. N-acetyl aspartate, myo-inositol, glutamate and glutamine
(C). Screenshots from the iOS simulator.
