Hyperspectral Camera Selection for Interventional Health-care

Abstract: Hyperspectral imaging (HSI) is an emerging modality in health-care applications for disease diagnosis, tissue assessment and image-guided surgery. Tissue reflectances captured by a HSI camera encode physiological properties including oxygenation and blood volume fraction. Optimal camera properties such as filter responses depend crucially on the application, and choosing a suitable HSI camera for a research project and/or a clinical problem is not straightforward. We propose a generic framework for quantitative and application-specific performance assessment of HSI cameras and optical subsystem without the need for any physical setup. Based on user input about the camera characteristics and properties of the target domain, our framework quantifies the performance of the given camera configuration using large amounts of simulated data and a user-defined metric. The application of the framework to commercial camera selection and band selection in the context of oxygenation monitoring in interventional health-care demonstrates its integration into the design work-flow of an engineer. The advantage of being able to test the desired configuration without the need for purchasing expensive components may save system engineers valuable resources.
