TRiP98 makedoseramp command
makedoseramp outdose / target()
level(0.8,0.2) parabolic
gantry()
couch()
debug
corners
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.
- corners
-
Specifies that all eight corners plus the centre
of a voxel are checked whether they are inside the
target volume or not. By default only the centre is checked.
Specifying
corners
results in dose prescriptions
more consistent with the homogeneous dose prescriptions.
- 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.
