Abstract: It is necessary to place bolus on skin to increase the surface dose when using high-energy rays to treat superficial lesions because of its build-up effect. It is well known that the set-up reproducibility of hand-made bolus is poor, and the main concern of commercialized bolus is the inadvertent air gap between the bolus and irregular skin. Owing to the advantage of making individualized and complex-shaped bolus, 3D-printing technology is playing an important role in making the bolus. The aim of this review is to summarize the current research status of hand-made, commercialized and 3D-printed bolus materials and future development trend of the bolus, providing reference for clinical application.
