The Posiboard-2 Breastboard is a complete solution for the positioning of breast patients. Made of a low density foam core covered in an ultra-thin layer of carbon fiber, it allows the beam to pass through the Posiboard-2 from any angle with minimal attenuation. The Posiboard-2 can be positioned at eight angles, and accommodates several comfortable and adjustable arm support options. For additional support a breast cast can be mounted using a quick release system. When the Posiboard-2 is not in use it can hang on the wall with the supplied wall-mount plate.
