Why do I need to attend the Mould Room?

Whilst you are having your radiotherapy it is important that you lie in the same position each time you have your treatment and keep your head and neck as still as possible. To help you achieve this, you will need to lie with your head in a specially made head shell during your treatment.

It will also be necessary for the shell to be worn during any scans or other pretreatment planning sessions. During the planning procedure marks will be placed on the shell to enable the radiographers to set up your treatment accurately. This means you should not require any marks on your skin.

Men with thick facial hair should shave or short trim facial hair before attending for this procedure.

The finished shell is made from thin, lightweight clear plastic material which is moulded to fit over your head and neck.

How is the shell made?

  • Before starting the procedure the mould room clinical technologists who manufacture your head shell will explain in detail how the shell is made and will answer any questions you may have.
  • In order to make the shell an impression of your head is taken, usually with plaster bandages. The shell is manufactured in two separate parts to help the fitting. Your mouth and nostrils will be left uncovered whilst the impression is taken and holes are provided in the finished shell to allow you to breathe comfortably.
  • The moulding procedure is not at all painful and normally takes around five minutes to complete. It can be a little messy so please wear old clothes for your appointment.

Custom head shell

The manufacture of a custom made shell will usually require more than one mould room appointment as it is produced in stages and will require fitting. The mould room clinical technologists will confirm your next appointment shown on your schedule.
