Title: Kevin Sam: Innovator in Cerebrovascular Imaging

Introduction

Kevin Sam is a notable inventor based in Toronto, Canada. He has made significant contributions to the field of cerebrovascular imaging, holding 2 patents that enhance the assessment of cerebrovascular reactivity (CVR). His work focuses on improving imaging techniques that can lead to better diagnosis and treatment of cerebrovascular diseases.

Latest Patents

One of Kevin's latest patents is titled "Imaging abnormalities in vascular response." This innovation utilizes Z maps combined with a standardized stimulus, specifically targeting arterial partial pressures of carbon dioxide. The results provide enhanced images for assessing pathological CVR. For instance, the Z-map assessment of patients with known steno-occlusive diseases in the cervico-cerebral vasculature has shown improved resolution in identifying the presence, localization, and severity of pathological CVR. This method effectively reduces the confounding effects of variability in test results, making it a valuable tool for comparing CVR images.

Another significant patent is "Imaging reductions in cerebrovascular reactivity." This system is designed to detect abnormalities in a subject's cerebrovascular response to a vasoactive stimulus in specific regions of interest within the brain. The system includes a gas delivery device and a control system that delivers controlled amounts of carbon dioxide. It also features an MRI scanner for generating response signals corresponding to the subject's vasoactive response. A computer analyzes these signals to compute quantitative measures of cerebrovascular reactivity, focusing on portions of the response that are sensitive to quantifying reductions in CVR.
