Radiation Therapy Bolus

If you are receiving radiation after mastectomy the therapist may place a bolus a flat piece of rubber like material on top of your skin which increases the radiation dose to your skin and to the tissues right below it. A plan like this wouldnt be possible any other way.

In radiation therapy bolus is often used when treating uneven areas of a patient such as at the nose or ears to make up for missing tissue or to provide build up of dose to the skin surface.

Radiation therapy bolus. References look up bolus in wiktionary the free dictionary. Elasto gel is easy to work with reusable on the same patient is mildly adhesive and conforms exceptionally well to body contours. All are pleased including our radiation oncologist medical physicist and therapists involved.

A bolus material can be used to alter the depth of the maximum radiation dose dmax during radiation therapy. It is a tissue equivalent material which means that it has similar properties to human tissue when it is irradiated.

Compensating for missing tissue or irregular tissue shape. Most treatment centers use an immobilization device to secure your position and make you more comfortable. In radiation therapy bolus is a waxy tissue equivalent material placed on the skin surface to homogenize or modulate the range of the dose from external beams of radiation.

The bolus fit very well and the dosimetry is excellent especially with regard to 90 dose conformity. Materials are frequently used in high energy radiation therapy in order to deliver the prescribed dose to the patients skin surface. It may be easily cut with scissors to the desired size and shape.

It is widely used in practice to reduce or alter dosing for targeted radiation therapy. The bolus should be tissue equivalent sufficiently flexible to conform to the patient surface durable and cost effective. We 3d printed then scanned the bolus on the patient.

In radiation therapy bolus is a material which has properties equivalent to tissue when irradiated. Commonly used 5 and 10 mm thick boluses develop full skin dose needing removal for the latter half of treatment and requiring two treatment plans to be generated. Superflab increases the targeted radiation dose during photon and electron treatment by providing scattering of the beam and build up of the radiation dose at the skin surface.

It must be possible to mould the bolus to fill the tissue space. The material was designed to conform completely to a variety of uneven surface geometries eliminating air gaps and further dose absorption. Radiotherapy treatments of post mastectomy chest walls are complex requiring treatment close to skin necessitating bolus use.
