Current imaging modalities used for measuring CBF has various limitations that restricts its usefulness especially in the neuroscience intensive care unit (NSICU). Here, the use of Time-gated DCS (TG-DCS) which has significant advantages compared to its predecessor, CW-DCS, was proposed as the solution. However, this technology is still in its infancy and its clinical capability has yet to be established. To show the feasibility of deploying TG-DCS in NSICU settings, the time-domain analytical model for TG-DCS was expanded for multi-layered cases. Next, CW-DCS was validated in humans and in NSICU settings on patients suffering from Traumatic Brain Injury (TBI). A prototype 1064nm TG-DCS system was built and validated on several in-vivo experiments. Finally, the feasibility of the system was shown by deploying it in NSICU settings for measuring CBF in TBI patients. Lastly, deep learning was used to show the feasibility of obtaining real-time results. 2021-12-17 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1637169598865539 http://rave.ohiolink.edu/etdc/view?acc_num=wright1637169598865539 restricted--full text unavailable until 2022-12-17 This thesis or dissertation is protected by copyright: some rights reserved.
