Reports on treatment times
Verbakel et al. :
“Delivery times for
standard IMRT
using sliding window are much
longer than for
RapidArc
for reasons which include the fact that
(1)
no radiation
is delivered
during gantry rotation
between fields,
(2)
multiple carriage groups
are needed for large PTVs and
(3) time required for each field as
complex fluence
distributions
require
small leaf openings
