Jet helps data process
Figure 1: Overview of modules and data structures in JET. a) Image representation of the JET modules in sequential order and its data structures that exist to operate each module. b) Sequential order of spectrum registration correction within the third module. The main function of JET is operated in the spectrum registration module where parameter corrections will be performed on the incoming data to quantify metabolite concentration.
Figure 2: Spectrum registration correction using JET and its performance using error analysis for different signal noise ratios. a) Spectrum registration correction in sequential order of the spectras. It can be observed that after each correction, the DIFF spectra improves. b) Bar graph representation of frequency estimation error for different SNRs. c) Bar graph representation of phase estimation error for different SNRs. It can be observed that JET reduces both parameter errors with greater SNR.
