these meetings to ensure coordinated and patient- centered care. Before the procedure, RTTs conduct individual consultations, providing detailed information about treatment steps and addressing patient questions, which increases patient satisfaction and trust. On the procedure day, RTTs prepare patients by assessing vital signs, inserting a peripheral venous catheter, and performing a bladder scan. In the operating room, they prepare sterile instruments, confirm applicator positioning using X-ray imaging, and assist physicians during the procedure — including ultrasound guidance, operation of the treatment unit, and radiation delivery. After treatment, RTTs remove applicators or needles, inspect for bleeding, ensure patient stability, and document all steps in the medical record. Beyond gynecologic and urologic cases, RTTs also manage treatments for skin cancers, head and neck lesions, and keloids, including catheter removal and hemostasis. This workflow demonstrates the RTT’s combined clinical and technical expertise, ensuring precision, patient safety, and procedural efficiency. Conclusion: Swedish brachytherapy RTTs perform a highly autonomous and technically advanced role. Their integration of clinical care, technical proficiency, and multidisciplinary collaboration contributes significantly to the high standards of safety and quality in Swedish brachytherapy. The Swedish model exemplifies how RTT competences enhance patient experience and treatment outcomes. Keywords: Competens of RTT´s, References:
interventions. In the remaining two cases, the tools are not used in clinical practice, as the solution provided is not sufficiently accurate. Most of the centres (67.7%) consider the possibility of automatic catheter reconstruction as highly beneficial, with no loss of knowledge. Finally, only 5/34 (14.7%) centres are equipped with BT automatic planning engine and in 1/5 cases the software isn’t used in clinical practice due to not satisfactory performance. The 88.2% of the centers that responded to the survey considered this solution useful for clinical practice, with a potential enrichment of the role of medical physicist (67.6%). In this field, the need for more accurate quality control is emphasised as well as the need for specific training in AI-based systems for their conscious and correct introduction and use in clinical practice (82.4%). Conclusion: Our survey showed that most of the centers that responded believe that the use of AI/automation in BT is beneficial for plan consistency and time savings without loss of knowledge. Keywords: Brachytherapy, AI, National survey Digital Poster 2966 The competences of RRTs in brachytherapy in Sweden Maria del Pilar Alvarez Bremberg Brachy, Karolinska University Hospital, Stockholm, Sweden Purpose/Objective: In Sweden, radiation therapy technologists (RTTs) working in brachytherapy are specialized oncology nurses with a subspecialty in radiotherapy. This abstract aims to describe the clinical and technical competences of Swedish RTTs within brachytherapy, highlighting their role in patient care, multidisciplinary collaboration, and contribution to treatment safety and quality. Similar initiatives have been reported internationally, emphasizing the evolving role and training needs of RTTs in interventional radiotherapy The description is based on current clinical practice at Swedish university hospitals offering brachytherapy. RTTs are fully integrated into multidisciplinary teams, collaborating closely with oncologists, medical physicists, anesthesiology staff, and ward personnel. Their responsibilities span the entire patient pathway — from pre-treatment consultation to post-procedure follow-up and documentation. Results: (AIRO & AITRO, 2022). Material/Methods: Weekly multidisciplinary conferences are held to review upcoming cases, mainly involving urological and gynecological cancers. RTTs participate actively in
