Achieving uniform dose with the use of a custom tissue compensator and a leveled beam for tangential breast fields

In order to achieve uniform dose distribution in intact breast treatments, wedges can be employed. This paper will describe a custom compensator made from brass chips used in conjunction with a leveled beam and a custom "cast" to treat breast shapes that are less suited to a standard wedge set up. Materials and design, dosimetry, criteria, efficacy and results will be described.
