Thermographic Pattern Calculator


A product of research: applied to the analysis of vertebral subluxation.

Created by the Sherman College of Straight Chiropractic Research Department.

This software was developed as a special tool to help researchers and practitioners assess the similarity between pairs of thermographic scans. The program uses data exported from the TyTron C-3000 and calculates a set of congruence factors using 5 different algorithms.

Update your Pattern.exe file

Installation instructions:

  1. Save the setup file to a directory on your hard drive.
  2. Use WINZIP to unzip the files.
  3. Run the file Setup.exe
  4. When setup is complete, run Pattern.exe

Operating instructions:

  1. Open thermal scan files into the File1 & File2 boxes by clicking on the filename and using the dialog box to browse for files.
  2. Click on each of the graph buttons above the graph viewbox. This shows you your data and also performs a needed stage of normalization.
  3. Use the Clear button to get a clean screen for viewing individual scans.
  4. Use the sliders at the left and right of the viewing screen to restrict the viewing area, clipping out gross incongruencies at the ends.
  5. Use the "Shift Chart Up" slider to adjust the vertical alignment of the charts if needed.
  6. Use the "Slopes" button to calculate a slope chart.
  7. The "Smoothing" button produces much nicer slope charts, you can use it as many times as you like on the data.
  8. Select the Congruence Algorithm(s) you like and note the congruence factors in the table.
  9. Red, yellow and violet bars appear on the left margin of the viewing box when the Slope and Stewart/Boone methods are used. The colored areas show which parts of the line charts shown on the viewbox are in congruence. Red is for the Slope Comparison, yellow is for the r% and violet is for the t%.
