A333 Angiography-like neurovascular training without radiation utilizing optical cameras and virtual roadmap imaging

<h3>Introduction</h3> At present, non-virtual neurovascular training can be performed using either an angiographic suite under fluoroscopic guidance (entailing radiation exposure) or direct optical visualization with a camera-based system. The angiographic approach offers high-fidelity visualization and catheter control but is constrained by the limited availability of such specialized facilities, whereas the camera-based approach can be implemented virtually anywhere yet lacks comparable realism in key procedural aspects. <h3>Aim of Study</h3> Development and evaluation of a novel camera-based angiography training system (CBATS) that generates artificial angiograms and roadmaps, thereby combining the advantages of both imaging techniques while eliminating radiation exposure. <h3>Method</h3> Three distinct aneurysm models were integrated into a novel neurointerventional training platform, which was evaluated by neurointerventionalists across three training imaging modalities (conventional digital subtraction angiography (DSA), camera-only visualization and CBATS) to simulate general endovascular procedures. Following the training sessions, a questionnaire-based evaluation was conducted to compare the performances of the camera-only and CBATS approaches with the conventional DSA, which served as the gold standard. <h3>Results</h3> Ninety percent of the raters agree that the visual realism of our CBATS training system is comparable to real angiography and offers a significant advantage over the camera-only variant. The absence of radiation, in particular, was rated as a major advantage by 90% of the raters. <h3>Conclusion</h3> In summary, our angiography-like training system is considered comparable to a real angiography system in terms of realism for the training scenarios addressed. However, it offers the advantage of being radiation-free and can be set up in almost any location. <h3>Conflict of Interest</h3> No
