Radiation therapy, or radiotherapy, is a common course of treatment for patients battling cancer. These treatments aim to target and kill cancerous cells, frequently with the use of a bolus to attenuate the radiation beam to alter the dose at desired tissue depths.1,2 Although boluses have not historically been patient-specific, 3D printing is making personalization more accessible.
Patient-specific boluses have shown an improvement in patient conformality as well as demonstrated improved radiotherapy plan dose conformity.3 VSP® Bolus is an FDA-cleared patient-specific solution that simplifies access to personalized boluses. The VSP Bolus service model enables clinicians to use an FDA-cleared patient-specific bolus for their oncology cases with limited device design burden. By providing a straightforward path from design to delivery, radiation oncology gains the benefits of elastomeric, patient-specific devices without the barrier-to-entry of design expertise or the purchase of software or equipment.
