Speech Title: "An Efficient Evaluation of RF Transfer Function of Active Implantable Medical Devices in Homogeneous and Heterogeneous Environment"
Abstract: Both the Tier-3 and Tier-4 methods proposed in ISO/TS 10974 for assessing the radiofrequency safety of active implantable medical devices have limitations in practice. The transfer function proposed in the Tier-3 method can only be measured individually for each implant and only for homogeneous tissue environments, while Tier-4 requires significant high-speed computing resources. In this study, machine learning algorithms are proposed to predict the transfer function both in homogeneous and heterogeneous tissue environment. The results show that this approach is feasible and performs well in the prediction task. This work will significantly reduce the computational resources required for RF safety assessment and greatly improve the efficiency of the assessment, as well as provide a more accurate result for implants with relatively complex implant environments.

Speech Title: "AI for Objective Assessment of Medical Imaging Systems"
Abstract: Medical imaging systems designed for specific tasks (e.g., tumor detection) should be objectively assessed via task-based measures of image quality (IQ). Task-based measures of IQ quantify the performance of an observer for specific tasks. They have been commonly used as figures of merit for guiding the evaluation and optimization of medical imaging hardware, software, and display devices. Virtual imaging trials and numerical observers are often employed when exploring and evaluating medical imaging systems. This talk will introduce some of my work on AI for addressing challenges in task-based assessment of medical imaging systems.
