Patent number: 11880989Abstract: Z maps combined with a standardized stimulus in the form of a targeted arterial partial pressures of carbon dioxide provide surprisingly enhanced images for the assessment of pathological CVR. For example, the z-map assessment of patients with known steno-occlusive diseases of the cervico-cerebral vasculature showed an enhanced resolution of the presence, localization, and severity of the pathological CVR. Z-map have been found to be useful to reduce the confounding effects of test-to-test, subject-to-subject, and platform-to-platform variability for comparison of CVR images showing the importance of combining this analysis with the standardized stimulus.Type: GrantFiled: October 24, 2016Date of Patent: January 23, 2024Assignee: THORNHILL SCIENTIFIC INC.Inventors: Joseph Fisher, Olivia Sobczyk, Adrian P.
