Oncologists and physicists. For this treatment, due to dose calculation in water, density of material used for manual or 3-D printing moulds should be verifie to be water equivalent. On the other side we can propose new treatment techniques for the patient base on Alpha and Beta emitters. These two new methods are on the border between interventional radiotherapy and nuclear medicine. The physicist contribution covers radioactive source measurement, dose calculation, safe treatment delivery and radioprotection rules during the treatment. Before treatment delivery, especially for interventional radiotherapy and X-ray treatment, tumour size and depth verification by ultrasound is very useful for making decisions about treatment technique. FLASH-RT therapy is promising from a radiobiology point of view but still needs accurate descriptions of the physical parameters and suitable detectors to ensure optimal pulse size and repetition frequency of the FLASH dose. In case of re-irradiation the radiobiology calculation is prepared by the physicist and discussed with The Radiation Oncologist. Multidisciplinary meetings and discussions regarding the best treatment options for patients are a part of a medical physicist’s routine work.

Scienze Radiologiche ed Ematologiche, Università Cattolica del Sacro Cuore, Rome, Italy Abstract: The role of Radiation Therapy Technologists (RTTs) in the management of patients undergoing interventional radiotherapy for non-melanoma skin cancer is critical in ensuring the success of modern treatment protocols. RTTs play a pivotal role in the direct application of therapeutic procedures, maintaining precision and safety in the delivery of skin radiotherapy. Their expertise not only facilitates the technical execution of treatments but also significantly influences patient experiences and outcomes. By integrating advanced imaging and treatment techniques, RTTs contribute to the accurate targeting and minimization of radiation exposure, which is vital for achieving local control while preserving surrounding healthy tissue. In this context, RTTs are integral to the interdisciplinary team, working closely with oncologists, physicists, and nursing staff to optimize treatment plans and adapt therapies based on individual patient needs. Their involvement extends beyond treatment delivery to include patient education on the management of side effects, thereby enhancing compliance and comfort. Furthermore, RTTs are actively engaged in the continuous monitoring and assessment of treatment efficacy, using their insights to refine procedures and contribute to clinical research aimed at advancing skin radiotherapy. 4757

By focusing on the comprehensive role of RTTs, this discussion underscores their essential contribution to improving therapeutic outcomes and patient quality of life in the management of non-melanoma skin cancer.

This presentation will explore how RTTs support patients through their cancer journey by:

1. Ensuring precise and safe treatment delivery through state-of-the-art radiotherapy techniques; 2. Enhancing patient understanding and management of radiotherapy procedures and side effects; 3. Collaborating in an interdisciplinary framework to tailor treatments to individual patient needs; 4. Contributing to research and innovation in the field of skin radiotherapy.
