Construction and Application Exploration of an Emergency CT Case Library for Medical Imaging Technology Based on PBL Integrated with Virtual Simulation

The training of medical imaging technology professionals in the emergency field faces challenges such as tight clinical teaching resources, high-risk scenarios, and insufficient practical opportunities. To address the contradiction between traditional teaching models and the urgency and complexity of emergency medicine, this paper proposes and explores a new teaching model of constructing an emergency computed tomography (CT) case library based on “problem-based learning (PBL) integrated with virtual simulation technology”. The paper systematically expounds the construction concept, design principles, content framework, and key technical paths of the case library, elaborates on the design and implementation strategies of the PBL teaching process, and analyzes the teaching effect through preliminary application feedback. The research shows that this model can effectively simulate the real emergency environment, integrate theoretical knowledge, clinical decision-making, technical operations, image diagnosis, and team collaboration, providing students with a safe, controllable, and repeatable comprehensive training platform, which has significant practical value and promotion significance for cultivating high-quality, application-oriented medical imaging technology professionals who can quickly adapt to clinical positions.
