            <p>The integration of photonics into catheter-based platforms represents a critical advancement in minimally invasive diagnostics and targeted interventions. This comprehensive course provides a rigorous examination of biophotonic catheters, bridging the gap between fundamental optical physics, intricate device engineering, and advanced clinical deployment. Participants will systematically explore the architectural constraints and scanning logic that dictate catheter design, distinguishing these optical approaches from traditional modalities such as ultrasound and fluoroscopy. By establishing a robust foundation in device mechanics and spatial resolution, the curriculum seamlessly transitions into an in-depth analysis of structural imaging techniques, with a primary focus on intravascular Optical Coherence Tomography (OCT). Learners will evaluate inherent depth-resolution trade-offs, operational prerequisites such as blood clearance, and the synergistic diagnostic potential of hybrid systems that incorporate Intravascular Ultrasound (IVUS) and Near-Infrared Spectroscopy (NIRS) for comprehensive tissue and vulnerable plaque characterization.</p>

<p>Beyond structural assessment, the program advances into the sophisticated realm of molecular and functional imaging, detailing the operational principles of Near-Infrared Fluorescence (NIRF), Raman spectroscopy, and emerging photoacoustic platforms. As these cutting-edge modalities transition from the laboratory to the catheterization suite or endoscopy unit, mastering the underlying technical mechanics becomes paramount. The course critically examines dynamic scanning artifacts, including nonuniform rotational distortion (NURD), and outlines rigorous quality assurance protocols to mitigate common misreads and technical failure modes. Furthermore, the curriculum addresses the multifaceted barriers to clinical translation, encompassing regulatory safety constraints, biocompatibility, and health-economic stakeholder priorities. By synthesizing technical fidelity with evidence-based clinical decision-making, this program equips interventionalists, biomedical engineers, imaging scientists, and health-system leaders with the critical insights required to evaluate, optimize, and implement next-generation biophotonic technologies across diverse intraluminal environments.</p>
