mitk::GantryTiltInformation::GetTiltCorrectedAdditionalSize
double GetTiltCorrectedAdditionalSize(unsigned int imageSizeZ) const
The shift between first and last slice in mm.
mitk::GantryTiltInformation::GantryTiltInformation
GantryTiltInformation()
Just so we can create empty instances for assigning results later.
mitkPoint.h
mitk::GantryTiltInformation::IsRegularGantryTilt
bool IsRegularGantryTilt() const
Whether the shearing is a gantry tilt or more complicated.
mitk::GantryTiltInformation
Gantry tilt analysis result.
Definition: mitkGantryTiltInformation.h:38
mitk::GantryTiltInformation::GetMatrixCoefficientForCorrectionInWorldCoordinates
double GetMatrixCoefficientForCorrectionInWorldCoordinates() const
