The New Thermometry with Light: Fiber Optic Sensors and Hyperspectral Imaging for Monitoring Thermal-Based Therapies for Localized Tumors

Hosted By: Optical Biosensors Technical Group

13 April 2023 10:00 - 11:00

Eastern Time (US & Canada) (UTC -05:00)

The light is a brilliant tool for medical applications, as it provides solutions for both minimally invasive therapies and their monitoring and optimization. Laser-based image-guided interventions provide a treatment option for cancer patients who may not be surgical candidates. Achieving optimal therapeutic outcomes relies on precise and controlled energy delivery localized to targeted tissues.

Recently, fiber optic sensors (FOSs) have emerged as an optimal tool to control laser- and, more in general,
energy-based therapies. Their small size, high accuracy, intrinsic safety, electrical passivity, and compatibility with diagnostic systems, make FOSs ideally suited for a broad variety of applications in life sciences, medical monitoring and diagnostics, such as temperature monitoring for thermal-based therapies for localized tumors.

In this webinar, Paola Saccomandi will present emerging applications of FOSs for thermometry and feedback-controlled delivery of laser treatments. Fiber Bragg grating sensors and distributed sensors will be described and discussed for the specific application. While FOSs allow measuring and controlling the tissue temperature distribution evolving during laser treatment, novel solutions are needed to directly monitor the thermal state of biological tissues. Thus, this webinar will also discuss an innovative hyperspectral imaging approach for monitoring and predicting the thermal state of biological tissues based on the measurement of its optical “fingerprint.”
