Your beam directional shell keeps you in the right position while you have your radiotherapy treatment.
You wear it for just a short time at each session.
Technicians in the mould room make the shell.
It is made of thin, clear, lightweight plastic. The technicians mould it to fit over the part of your body that must be kept still. Later your radiographers put marks on the shell so they know exactly which part of your body to treat.
You will come to the mould room, usually for three visits, so that the technicians can make your shell.
When you arrive they will explain what they are going to do, and answer any questions you have.
They take an impression of part of your body, usually with Plaster of Paris bandages. It doesn’t hurt, but it can be a bit messy. It is best to wear your older clothes!
If your head or neck is going to be treated, the finished shell will have holes in it so that you can breathe easily. Your mouth and nostrils are left uncovered while your shell is made.
Your first visit to the mould room is likely to last about 30 minutes. The second could take up to an hour. The third visit takes about 15-20 minutes. These times are approximate, and may vary.
When your shell is ready you will be able to come back for treatment planning.
If you have any queries about your visit, please ask your Oncologist or Clinical Nurse Specialist.
