That is, optional range shifter information is included,
where the <s i>
are the individual range shifter slice thicknesses
(in mm water equivalent) and the <on_off i>
indicate slice in/out by specifying a 1

,
respectively. Note that as many
slices
settings must be specified as there are
shifter
slices.

Note that couchangle
and chair
are mutually exclusive.
For all format versions
all values must be present and reasonable (i.e. no mass < 0 ).
The files are named <pppppp>1<vv><bb>.rst
,
where <pppppp>
denotes the patient id,
<vv>
the plan version number
and <bb>
the field number in order to distinguish for
multiport treatment.
The usual file name extension is .rst
.
An example is here
Their format is virtually identical with the
CAVE M format
20010201 and later.
The only difference is the sistable
,
which may be 0
because no MEFI operation is possible.
Although this format is obsolete, it is described here for backward
compatibility. It was used for the old scanner system in CAVE A.
For m
energy slices there are m+1
files.
The first one (allcuts.dat
) is a steering file for all others.
Format:
<mass [amu]>
<charge>
<max field extent [mm]>
<n>
<dose-scale-factor>
<shifter-slice 1 [mm]> ... <shifter-slice 5 [mm]>
<totalmin> <totalmax>
<energy 1> <IC-cal. factor 1>
...
<energy n> <IC-cal. factor n>
The energies start with the highest one.
The dosefactor is optional and causes all particle numbers to be
multiplied with that factor.
The remaining m
files (cutxx.dat, xx=0..m-1
, padded to the left with a zero)
describe one energy slice each.
Format:
<energy>
<shifter-on-off 1> ... <shifter-on-off 5>
<min-particles> <max-particles>
<n>
<xpos1 [mm]> <ypos1 [mm]> <#particles1>
<xpos2 [mm]> <ypos2 [mm]> <#particles2>
...
<xposn [mm]> <yposn [mm]> <#particlesn>
