Super-Flex Transparent Bolus material is calibrated with photon and electrons in the energy range greater than 1 MeV. This assures accurate measurement and administration of the prescribed dose of radiation. Close quality control of the thickness promotes quality results time after time. The materials do not flow, creep, sag out of shape and may be cut with scissors to fit the patient and layered as required to build up the thickness. The material is available with or without skin/film and is available in a wide range of thicknesses and sizes.
