This code adapts the position, energy and weight of beamlets to keep planned dose levels to patients taking the specific geometry of a given fraction into account.
The code reads a patient directory structure as given by MCAuto-Astroid to get the necessary treatment parameters.
- None at the moment
- To adapt to internal coordinates the CT's coordinates undergo:
x ↔ ztransformation - Offsets are internally defined as the distance from the lower left corner (not the center of the voxel) to the isocenter. They are transformed as:
x ↔ z,x → -x,offset -= 0.5*voxn*voxd - Couch angle is reversed and gantry angle is taken as
ang = 270-ang - Positions and directions read from Tramp are transformed as in:
x → -y,y → -x - Same transformation is applied to treatment planes
