# Reference for geometry: Jabbari et al, J Med Signal Sens 3(3):172-179

############################# Parameter Descriptions #################################
# SAD: Source axis distance (nominal distance from x-ray target to gantry rotation axis)
# The parameters in Jaws.txt are intended as defaults to be adjusted in higher level
# parameter control files FullTxHead.txt or Field.txt
#
# Parameters available for adjustment...
# SourceToUpstreamSurfaceDistance: Distance from x-ray target to jaw
# PositiveFieldSetting: Positive jaw position projected to isocenter
# NegativeFieldSetting: NegativeFieldSetting <= PositiveFieldSetting
# Jaw/RotZ: Jaw orientation, dependent on direction of jaw travel along IEC_B
# NegativeFieldSetting: NegativeFieldSetting <= PositiveFieldSetting (IEC X1)
# PositiveFieldSetting: Positive jaw position projected to isocenter (IEC X2)
#
# Parameters calculated from other parameters...
# SAD: Source axis distance (nominal distance from x-ray target to gantry rotation axis)
