I am new to the community and am starting to use 3D slicer on images of veterinary patients in the context of synchrotron micro beam radiotherapy.
In this setting, during radiotherapy, we use masks that we place in front of the beam to shape it.
The shape of the used mask is recorded in the dicom file of the RTplan in the tags that characterize the “block sequence” (300a, 00F4) (300a, 0106).
When I open in 3D slicer the CT scan and the RTplan, obviously the shape of the beam does not turn out to be correct because it takes into account the position of the Jaws.
What can I do to give the beam the desired shape? Or to make it read the shape of the “block sequence”?
I already tried to add a table and give a “new shape” to the MLC collimator but I can’t get the correct shape.
I hope I have been clear–in any case, I am here for any clarification.
Thank you very much everyone!
