Class PlotPixel

java.lang.Object

edu.rit.mri.PlotPixel

public class PlotPixel
extends java.lang.Object

Class PlotPixel is a main program that displays the results of a spin relaxometry analysis of a magnetic resonance image.

The program displays a plot of the measured spin signal for the pixel at a given index. The program reads the spin signal from a spin signal data set file using class SignalDataSetReader.

The program includes a plot of the fitted spin signal for the pixel as determined by the spin relaxometry analysis. The program reads the analysis results from a tissues data set file using class TissuesDataSetReader. The program also prints the tissues' computed spin densities ρ_j, spin-lattice relaxation rates R1_j, and spin-lattice relaxation times T1_j. The program prints χ², the sum of the squared differences between the measured spin signal and the fitted spin signal; the degrees of freedom (dof) in χ²; and the standard deviation σ of the errors in the measured signal derived from χ².

If no tissues data set file is specified, the analysis results are not plotted or printed.

Usage: java edu.rit.mri.PlotPixel signalfile [ tissuesfile ] index
signalfile = Spin signal data set file
tissuesfile = Tissues data set file
index = Pixel index
