Don’t loose the details
Comparison of a measured
and calculated cross-
plot (at 5 cm depth) of
an intensity modulated
field incident on a flat
phantom. A diode-array
(MapCheck; Sun Nuclear
Corp.) was used for this
comparison, which shows
that 97.5% of the points
meet 3% criteria even
though DTA (distance to
agreement) for a few
points is 10 mm.
Can be crucial for
organs at risk.
