Dose Points-based Adjustment of Dwell Times T
i
(DPO)
How can we avoid
“Black Holes”
- Negative Dwell Times?
-
As long as the linear Form of Equations, D ≈ T x 1/r²,
is used (mathematically attractive) there is no guarantee for
non negative T
i
-
DTGR is a method to moderate but
not
to solve the problem
-
There exist also other methods trying to limit negative T

,
e.g. Polynomial description of T
