Ph.D. student Sam Spink was the first author in our new paper which describes the design and performance of a new highly flexible wearable probe that uses near infrared light to probe breast tissue. Sam and the research team explored how paced (slow) breathing can be used to quantify the hemodynamic state of breast tissue, with the near future application of monitor breast tumors during chemotherapy. Thanks to the large and diverse team of engineers, physicists, and physicians for this one.
This paper is included in JBO's special series on WEARABLE, IMPLANTABLE, MOBILE, AND REMOTE BIOMEDICAL OPTICS AND PHOTONICS
Long time BOTLab member (Raeef was the first employee of the BOTlab in 2012 before becoming a Ph.D. student) successfully defended his Ph.D. His thesis is entitled: "FREQUENCY-DOMAIN DIFFUSE OPTICAL SPECTROSCOPY FOR CARDIOVASCULAR AND RESPIRATORY APPLICATIONS"
In this work we used SFDI to monitor optical scattering in prostate and breast animal tumor models. We found that the reduced scattering coefficient was strongly correlated with apoptosis, and the scattering power was strongly correlated with proliferation. This helped us track treatment response to cyclophosphamide and the antiangiogenic DC101. This work helps establish optical scattering as an important label-free optical marker of anti-cancer treatment response that can be used with other more common markers, such as oxygen saturation, hemoglobin levels, water, and lipids. It also helps make the case for frequency-domain and/or time-domain diffuse optical techniques such as SFDI, DOS, FD-NIRS, etc. which can quantify optical scattering in thick tissue.
Very excited about this one.
Darren’s new perspective article on wearable and remote patient monitoring during COVID-19 and beyond
I recently published a JBO perspective on wearable and remote patient monitoring during COVID-19 and beyond. I cover new tech, regulatory, and commercial changes that have encouraged a push towards remote patient monitoring during COVID-19, with a focus on optical technologies.
Eric Lochridge at SPIE also did a nice write up summary of my piece for SPIE news.
Check out this recent post on Karissa Tillbury and her student Wyatt Austin, who spent a summer in our lab developing an SFDI system as part of their NSF EPSCoR Track 4 project: "Diffuse Optical Imaging for Early Detection of Diabetic Polyneuropathy".
Darren gave an interview with the American Cancer Society to help support their Making Strides Event.
Our 2019/2020 Senior Design team has won the: Outstanding Senior Design Projects in Biomedical Engineering Award for their project: "Wearable SWIR Optical Probe for Measuring Lipid and Water Composition of Peripheral Edema"
