http://mercury.aapm.org/meetings/2001AM/pdf/6812-54410.pdf
In-air Off-axis Ratio (OAR(x,d)), defined as the ratio of dose at depth, d, in a miniphantom at off-axis point, x, to that on the central-axis, can be used to determine the incident photon fluence distribution φ(x) as well as μ(x)/μ(0), where μ is the attenuation coefficient. In our model, OAR(x,d) = exp(-μ(x)·d)·φ(x), where φ(x) is the photon fluence at surface

The off-axis ratio is defined as the ratio between the primary
dose off and on the central axis, sometimes also named off-center ratio or primary offcenter ratio.3-7 This ratio is required for calculations in asymmetric fields where the calculation point is not on the central axis. Eq. (2) presumes that H and OAR are mutually independent and that electron equilibrium is present.

A fenti linkben benne van off-center rationak is hívják, tehát eltolódási arány. Nem a tengelytől való eltérési arány, hanem a tengelyen kívüli és a középtengely közötti eltolódás/eltérés arányáról van szó (tehát a két tengely közötti arányról).

* Bocsánat, nem a két tengely között, hanem a tengelyen kívüli pont és a középtengely közötti eltolódás/eltérés aránya:
In-air Off-axis Ratio (OAR(x,d)), defined as the ratio of dose at depth, d, in a miniphantom at off-axis point, x, to that on the central-axis
Szerintem simán az eltolódási arány jó lesz.
