How to calculate a calibration equation
This movie is to illustrate how a calibration equation is obtained in polyGeVero-CT software.
The following can be seen in the movie:
- Imported CT cross beam calibration data that was obtained after special processing: see the movie of How to process example CT data
- The option of Edit/Show ROI is used for selecting ROIs related to the regions of quasi-uniform CT signal distributions as obtained after irradiation according to a cross beam calibration pattern
- Drawing a calibration relation and fitting a calibration function to experimental points
