The MEDISIP research group at Ghent University has introduced an innovative flat panel, patient-centered PET system that redefines scanner geometry and clinical work-flow. The design offers notable benefits, including improved spatial resolution and sensitivity, shorter acquisition times (30 seconds), and increased patient throughput. Despite these advances, two limitations persist: the continued need for medical personnel assistance during patient positioning and the increased upper body motion during upright scanning, even with ergonomic supports already integrated in the mock-up design. To address these aspects, this thesis proposes two interactive audiovisual tools: an animated 3D video guide to facilitate patient self-positioning (prototype stage), and a 30-second timer video aimed at improving postural stability and attentional focus during scanning.
