Physical limits of optical imaging

Physical limits of optical, photoacoustic and ultrasound imaging: sensitivity, specificity and quantitation Stanislav Y. Emelianov, Biomedical Engineering, University of Texas at Austin, Austin, TX, USA Learning Objectives: • Understand the fundamental principles of optical, ultrasound and hybrid (i.e., photoacoustic) imaging techniques • Know how optical/ultrasound/photoacoustic images are formed • Understand how imaging contrast agents can enhance contrast, signal-to-noise ratio and penetration depth in optical/ultrasound/photoacoustic imaging • Understand the ability of optical/ultrasound/photoacoustic imaging system to visualize desired properties of imaged tissue using imaging contrast agents or probes • Identify the role of contrast agents in basic science and clinical applications
