Researchers have discovered a way to utilize the capabilities of 3D printing to create Boluses which protect cancer patients in a more efficient manner. The boluses are created by taking CT scans and then printing out a model created from those scans. Once printed the bolus can be placed on an individual to protect certain areas from radiation therapy, while also providing lower doses of radiation to certain areas.
