“…Three-dimensional printing in radiation oncology is still in its infancy with potential applications undiscovered. The most common uses include creation of quality assurance phantoms and custom bolus [6] , with rare reports of custom shielding [11] , [12] , [13] . This report describes a novel technique for patient-specific scalp-shielding in TSEBT using 3D-printing which provided similar hair-preservation as would be expected for lead shielding, with the added benefit of customized shielding at the hairline.…”

“…Electron irradiations with various energies are used in electron beam therapy to treat tumour cells [3,6]. Among the different irradiation energies, the 6 MeV electrons are one of the most widely used electron beam therapy [6,26]. Hence, incident electron beam energy was set to 6 MeV during the evolution of the lead oxide-based flexible skin dosimeter.…”

Novel lead oxide-based flexible dosimeters with superior performance were experimentally tested for electron therapy. However, absorbed/transmitted primary particle fraction and secondary radiation distribution from the dosimeter surface have not been reported. These features should be specified to improve the dosimeter’s reliability for medical applications. Hence, the absorbed primary particle fraction, transmitted particle and secondary radiations distributions of lead oxide-based flexible skin dosimeter under the incident 6 MeV electron radiation have been investigated by pyPenelope Monte Carlo Simulation. The results have demonstrated that the generated secondary irradiation probabilities are not significantly high to enhance the therapeutic dose abnormally. In addition, the angular distribution of the scattered secondary irradiations is low. No abnormal changes were observed in the fraction and energy distribution of the transmitted primary electrons. Hence, it can be concluded that the designed structure has promising potential to be used as dosimeters in electron beam therapy.

“…Craft et al published the first case of a patient treatment using a custom 3D-printed skin shield using Bronzefill, and their methods have been implemented at our institution for patient-specific skin shielding. 8 Machined brass, a copper-zinc alloy renowned for its exceptional durability, thermal conductivity, and machinability, offers another approach to skin shielding. Machined brass enables the creation of skin shields with reduced thickness while maintaining structural integrity.…”

PurposeSkin collimation is a useful tool in electron beam therapy (EBT) to decrease the penumbra at the field edge and minimize dose to nearby superficial organs at risk (OARs), but manually fabricating these collimation devices in the clinic to conform to the patient's anatomy can be a difficult and time intensive process. This work compares two types of patient‐specific skin collimation (in‐house 3D printed and vendor‐provided machined brass) using clinically relevant metrics.MethodsAttenuation measurements were performed to determine the thickness of each material needed to adequately shield both 6 and 9 MeV electron beams. Relative and absolute dose planes at various depths were measured using radiochromic film to compare the surface dose, flatness, and penumbra of the different skin collimation materials.ResultsClinically acceptable thicknesses of each material were determined for both 6 and 9 MeV electron beams. Field width, flatness, and penumbra results between the two systems were very similar and significantly improved compared to measurements performed with no surface collimation.ConclusionBoth skin collimation methods investigated in this work generate sharp penumbras at the field edge and can minimize dose to superficial OARs compared to treatment fields with no surface collimation. The benefits of skin collimation are greatest for lower energy electron beams, and the benefits decrease as the measurement depth increases. Using bolus with skin collimation is recommended to avoid surface dose enhancement seen with collimators placed on the skin surface. Ultimately, the appropriate choice of material will depend on the desire to create these devices in‐house or outsource the fabrication to a vendor.
