Photonic Detection

This group involves the detection of photons as received from images, data links, and experimental spectroscopic studies to mention a few. Within its scope, it is involved in the design, fabrication, testing of single and arrayed detectors. Detector materials, structures, and readout circuitry needed to translate photons into electrical signals are considered by this group. Also included in this group is the integration of components such as lens, cold shields, and readout electronics into cameras. Research into higher efficiency, lower noise, and/or wavelength tunability is included here. Additionally, techniques to mitigate noise and clutter sources that degrade detector performance are within the purview of this group. In the imaging area, camera design, componentry, and circuitry are considered.

Medical Hyperspectral Imaging: Artificial Intelligence and Image-Guided Surgery

When: 7 January 2021, 13:00 - 14:00 Eastern Time

Register Now

Hyperspectral imaging (HSI) is an emerging modality for medical applications such as cancer detection and diagnosis, image-guided surgery, and computational and digital pathology. This webinar, jointly hosted by the Photonic Detection Technical Group and the Molecular Probes and Nanobio-Optics Technical Group, will provide attendees with an overview of state-of-the-art HSI technology and its specific applications.

Dr. Baowei Fei from the University of Texas at Dallas and UT Southwestern Medical Center will present various hyperspectral imaging technologies and their medical and biological applications. The webinar will focus on how deep learning methods are applied to HSI and how HSI techniques are developed for image-guided surgery. Promising results from both preclinical and clinical studies will be presented in this webinar. Future directions and potential challenges of medical hyperpsectral imaging will also be discussed.

Subject Matter Level:

  • Intermediate - Assumes basic knowledge of the topic

What You Will Learn:

  • An introduction to hyperspectral imaging
  • Overview of the status of hyperspectral imaging development
