Dose profile
Graphical presentation of the dose profile along a line z perpendicular to the tomographic
plane measured in the centre location of the head-dosimetry phantom:
z-direction = Beam height at rotation centre
Sensitivity profile
Sensitivity profile N/A - the resolution is substantially equal in z-direction.
