external beam radiotherapy (EBRT) CT scans. This process required three patient transfers: from the implant bed to the stretcher, from the stretcher to the CT scanner, and back to the stretcher. During this period, we treated 38 patients with cervical cancer out of a total of 124 Post-ImagingRing Workflow: The ImagingRing's dedicated CT system enables for flexible scheduling of IGBT procedures, eliminating the need for patient transfers between rooms for planning and verification. Total procedure time was calculated as the sum of planning CBCT and treatment delivery times. During this period, we treated 52 patients with cervical cancer out of a total of 152 patients.The implementation of the ImagingRing resulted in a significant reduction in total procedure time averaging a one-hour saving per case. This streamlined workflow offers several advantages: Reduced Procedure Time: Eliminating patient transfers allows all IGBT procedures to be completed in a single room, saving approximately one hour per case.Enhanced patient Experience: Reduced patient mobilization improves comfort, decreases anxiety, and minimizes the risk of applicator displacement.Improved Treatment Accuracy: The capability to acquire CBCT scans both before and after treatment delivery enables for final verification of organ motion, applicator placement, and changes in bladder, bowel, and rectal positions Conclusion: The ImagingRing system significantly improves IGBT workflow by reducing procedure time, minimizing patient mobilization, and enhancing treatment accuracy. These benefits translate into enhanced patient care and may also increase the department’s treatment capacity Digital Poster Quality Assurance Strategies in Interventional Radiotherapy (Brachytherapy) for Head and Neck Cancer: Ensuring Precision in Treatment Delivery Elisa Placidi 1 , Bruno Fionda 2 , Francesco Bussu 3,4 , Enrico Rosa 1,5 , Valentina Lancellotta 2 , Patrizia Cornacchione 1 , Martina De Angeli 2 , Pierpaolo Dragonetti 2,6 , Francesco Pastore 7 , Leonardo Bannoni 2 , Maria Concetta La Milia 6 , Maria Antonietta Gambacorta 7,6 , Jacopo Galli 8,9 , Luca Tagliaferri 2,6 , Marco De Spirito 1,10 1 UOC Fisica per le Scienze della Vita, Fondazione Policlinico Universitario A.

The IRT process consists of four critical phases: implant verification, treatment planning, dose calculation, and treatment administration. This report aims to explore potential strategies for the effective implementation of treatment delivery in interstitial IRT, ensuring the most precise therapy for patients with H&N cancer. Material/Methods: We gathered data on all patients treated with interventional radiotherapy (IRT) at our Institutional Interventional Oncology Center using our electronic database for head and neck (H&N) cancer, spanning the period from January 2022 to December 2023. Our focus was specifically on anatomical sub-sites with treatment regimens exceeding 5 Keywords: IRT workflow, IGBT, patient confort 2696
