Enabling Biomedical Imaging Diagnostics using Optical Methods
<p>This thesis work applies optical schemes to existing biomedical imaging techniques to improve the performance of present state-of-the-art biomedical imagers, and is in two parts. In the first part, a fast and simple optical time-gate scheme for counting single photons is presented. The gate is …

Time-domain diffuse correlation spectroscopy: instrument prototype, preliminary measurements, and theoretical modeling
Near-infrared spectroscopy (NIRS) is an emerging diffuse optical imaging tool with both clinical and academic applications such as functional brain imaging, breast cancer detection, and cerebral health monitoring. Due to its non-invasiveness, high spatial and temporal resolution, and portability, …

Next generation near infrared (NIR) and shortwave infrared (SWIR) wearables for breast cancer imaging
… patient outcomes. Over the last two decades, diffuse optical imaging has been investigated as a potential solution to this problem. This noninvasive and inexpensive technology uses near or shortwave infrared (NIR or SWIR) light to illuminate tissue, and detects multiply-scattered photons. …

Diffuse Optical Tomography Methods for Imaging the Developing Brain
<p>Diffuse optical imaging (DOI) is a portable imaging modality that provides the ability to perform early and continuous monitoring of brain function in infants. Its methodology overcomes many of the technical and logistical challenges of performing magnetic resonance imaging (MRI) investigations …

Micro cameras as adjunct tools in biomedical applications
Biomedical imaging is one of the most impactful periprocedural tools and is used across a wide range medical applications. The eyes of the clinician are a key component in surgical decision making, and an image is often the first step in both diagnostic and interventional procedures. With the …

Cerebrovascular influence on brain and cognitive aging
… of quantifying cerebrovascular health using diffuse optical imaging in a sample of older adults. This method is based on the estimation of the arterial pulse across the whole scalp. From these estimates, three indices reflecting arterial health can be extracted: pulse amplitude, arterial …
