Silicone boluses provide a conformal and flexible solution to achieving required dose build-up in radiation therapy. This approach has been shown to be feasible for head-and-neck radiation therapy and when applied to treatment of nonmelanoma skin cancer, has introduced both dosimetric and workflow advantages. However, the method requires detailed software design to provide a mould for fabrication of silicone bolus. To date, no dedicated or regulatory cleared software solution has been available. This poster evaluates a new module of a commercial solution facilitating this technique.
The aim of this study was to develop and evaluate a workflow using Adaptiiv’s CE marked and FDA 510(k) cleared software technology to facilitate the design and production of a 3D printed silicone mould bolus, interfacing directly with the treatment planning system (TPS). The method is demonstrated in the treatment of an 81-year-old patient presenting a squamous cell carcinoma of the left ear and pre-auricular area.
