Description

Terahertz (THz) imaging refers to scanning tissue using a new class of electromagnetic waves with frequencies between 0.1 THz (or 100 gigahertz) and 2-3 THz, which is roughly 2000 times higher than the center frequency used in the new 5G cellphone telecommunication network. THz waves have been historically inaccessible to researchers outside large electron-beam facilities such as synchrotrons or without operating at cryogenic temperatures. But recently with the advent of ultra-fast femto-second lasers, this part of the electromagnetic spectrum has become widely democratized. In this talk, I will describe the progress in my research group the led to the invention of a new handheld terahertz three-dimensional scanner for use in clinical settings. This first-of-its-kind instrument is currently being tested in the DLAR facility, and is planned to be used in the first pilot human study of this technology at the Stony Brook Hospital in 2020. I will describe our work in elucidating the sources of the imaging contrast mechanisms of different tissue types in the THz frequencies, compared to MRI. Finally, I will overview the applications of THz imaging in diagnosis of various cancers, including skin (Basal Cell Carcinoma), breast, colon, glioblastoma, oral cancer and others.

Dates and Times

Start: 8/22/2019 12:00 PM
End: 8/22/2019 1:00 PM

Objectives

1. Introduction to the new Terahertz imaging modality, and the new handheld scanner technology (first and second generations) invented at the Stony Brook University.
2. Understanding spectroscopic signal contrast mechanisms that can be used to diagnosis normal from diseased tissue types and the physical limitations of the Terahertz imaging.
3. Brainstorming about future directions in Terahertz cancer diagnosis: real-time label-free spectroscopic tumor margin delineation - identifying new areas of collaboration.
