Brass Mesh Bolus, Off-White, 50cm x 50cm

Brass mesh bolus can be used for post-mastectomy chest walls using 4MV and 6MV photons.

When placing Brass Mesh over the breasts and there is a gap is between breast, use a piece of double stick tape between the breasts to secure the brass mesh down. Using the smooth side of the brass mesh bolus towards the patient will provide a better surface for the tape to adhere to and will be more comfortable for the patient.

When wrapping the brass mesh bolus around the sides of a chest wall, use a product such as Spandage (Items 674-308 through 674-312), gauze or Clear Plastic Wrap (Item 119-750) to hold the brass mesh against the skin to prevent hanging gaps.

If you are using 15MV or higher energy beam, there might be neutron activation which may increase the skin dose and/or give dose to the hands of the therapist who handles the bolus.  Some Patients have had skin reactions.  See papers "Skin dose effects of post mastectomy chest wall ect.” and “ Dosimetric assessment of brass mesh bolus for postmastectomy photon radiotherapy”.

The Brass Mesh Bolus has been painted off white to limit reflection when using surface tracking systems such as Vision RT or C-Rad.
