1092-1093 / 2605
Why do we say that?
The answer in a first approximation is
evident:
Beam shaping in depth :
Spread out Bragg Peak
Ridge filters or
1D scanning
Ex:
600 – 1000 rpm
4-8 scans/rotation (or more)
= 40-130 scans/sec in depth
(« fast repainting »)
Even compared to 1-1.5 hearth beats/sec
Beam shaping laterally
using scattering(or fast wobbling)
:
Ridge Filter
