TRiP98 Rst command
rst file / import() list debug
export() delete
read display
write inspect
reverseorder
raw
shift() factor()
Purpose
Handles raster files.
Note that this command has no relation to the field rasters used for
dose computation.
Parameters
- file
-
Name of a raster file.
Usually raster files have the extension
.rst
.
For read a (comma-separated) list of files
may be specified, which, however, must be compatible.
That is, they must have the same angle, SIS table, patient ID, etc.
After successful read they are merged into a single raster.
- import()
-
Not yet implemented.
- export(fmt)
-
Exports current raster file in some non-native format,
at present only
gd
is implemented to export for the
gd
plot program.
- read
-
Read a raster specified by file.
- write
-
Write the current raster to file.
The scan path optimization algorithm is defined by the scancap command.
- list
-
Lists some short info about the current raster.
- delete
-
Deletes the current raster.
- display
-
Displays the current raster. Not yet implemented.
- inspect
-
Show some internal info about the current raster.
- reverseorder
-
Writes raster slices in ascending energy order.
- raw
-
Writes raster slices in raw, unprocessed mode,
i.e. no suppression of positions with particle numbers of zero.
- shift(offsetx,offsety)
-
On
read
or
write
add the specified offset (in mm) to all raster positions.
- factor(fac)
-
On
read
or
write
multiply all particle numbers with the specified factor.
- debug
-
Debug switch. Lots of output!
Remark
Raster files with a version number >= 19980701 contain
couch and gantry angle. Earlier files are assigned default angles
on input. These defaults are defined by the
Scancap command
You may visualize raster scanner data using the
rv
shell command
Examples
-
rst xxx.rst /read
Reads the specified raster file.
-
rst x1.rst,x2.rst /read
Reads the specified raster files and merges them, if possible,
into a single raster.
-
rst my.rst.gd / export(gd)
Exports current raster in gd format
