ogo.calibration.standard_calibration.StandardCalibration¶ Bases:
ogo.calibration.calibration.CalibrationCalibration for standard calibration phantoms
This algorithm takes samples of a standard calibration phantom and determines the equation of best fit. This is typically done for solid phantoms. The calibration equation is straight forward:
\[\rho = m * HU + b\]Given sames of density and Hounsfield Units in the scan field of view, an equation of best fit is determined.
The output densities are in units of whatever calibration phantom was used. It is the users responsibility to know what those units are.
