makedoseramp outdose / target()
level(0.8,0.2) parabolic
gantry()
couch()
debug
Purpose
Generates an inhomogeneous dose cube (ramp along the field direction)
Parameters
- outdose
-
Output dose cube.
- target()
-
- gantry()
-
- couch()
-
Specify field direction, as for the field command.
- level([posprox,]doseprox,[posdist,]dosedist)
-
List of numbers (
0<dose<1) specifying the proximal and distal
dose levels in the target volume.
Two forms are possible:
- 2 numbers specifying only the relative (0..1) dose levels
- 4 numbers specifying additionally the relative (0..1) position
of the ramp edges within the target volume.
Voxels beyond the edges receive the minimum and maximum specified dose levels, respectively.
- parabolic
-
Interpolate a parabola (rather than a straight line) between
the level positions. This is particularly useful for adapting to
absorbed dose shapes originating from biological optimization.
- debug
-
Debug switch. Lots of output !
Remark
A CT and a target volume must exist.
Examples
makedoseramp ramp.dos / couch(-180) gantry(0) level(0.8,0.2)
Creates a normalized dose distribution which drops from 80% in the proximal voxel
of the target volume (in beams eye-view) along the direction specified by couch and gantry angle to 20%
in the distal voxel of the target volume.
The target coordinates are taken from the target volume definition.
makedoseramp ramp.dos / couch(-180) gantry(0) level(0.1,0.8,0.9,0.2)
Creates a normalized dose distribution which drops from 80%
at 10% relative depth from the proximal voxel
of the target volume (in beams eye-view) along the direction specified by couch and gantry angle to 20%
at 90% relative depth from the proximal voxel of the target volume.
That is, the depth is measured from 0 to 100% in beams eye-view from proximal to distal
target voxel. Voxels beyond the edges receive the 0.8 and 0.2 levels, respectively.
The target coordinates are taken from the target volume definition.
