The Heat Map tool works by generating a heat map that visually illustrates the difference between two image files.
The tool is accessible by the lefthand navigation bar (the 6th icon from the top).
To use the heat map tool, first select your starting image (also called the base layer), the select your operand image, and click the save icon. Depending on the differences you want calculated, your base layer can be the preoperative image or the simulated image. After you select the base layer, you will select the layer you would like to make the comparison by. An important point of clarification: the first selection, the base layer, is the 3D mesh the heatmap will be display on. The second selection, the operand layer, is the 3D meshed that the distances are calculated from for generating the color map.
After you have made both the base layer and the operand layer selections, click the save icon. MirrorMe will start "calculating differences" to prepare the heatmap visualization.
Use the legend that appears on the right-hand side of the screen to view the calculated differences in millimeters. You can save your results, or perform a new analysis.
The gif below walks through the initials steps of selecting the base layer, the operand layer and saving the selections to begin generating the heatmap.
