Title: The Innovative Contributions of Adrian P Crawley

Introduction

Adrian P Crawley is a notable inventor based in Toronto, Canada. He has made significant contributions to the field of cerebrovascular research, holding 2 patents that focus on enhancing imaging techniques for assessing cerebrovascular reactivity.

Latest Patents

Crawley's latest patents include groundbreaking work on imaging abnormalities in vascular response. His first patent describes a method using Z maps combined with a standardized stimulus, specifically targeting arterial partial pressures of carbon dioxide. This innovative approach provides enhanced images for assessing pathological cerebrovascular reactivity (CVR). For instance, the Z-map assessment of patients with known steno-occlusive diseases of the cervico-cerebral vasculature has shown improved resolution in identifying the presence, localization, and severity of pathological CVR. The use of Z-maps has proven effective in reducing variability in CVR image comparisons across different tests and subjects.

His second patent focuses on 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 to achieve targeted increments or decrements in the subject's PetCO. An MRI scanner generates response signals corresponding to the subject's vasoactive response, while a computer analyzes these signals to compute quantitative measures of cerebrovascular reactivity.
