Title:
APPARATUS, SYSTEMS AND METHODS FOR MAPPING OF TISSUE OXYGENATION
Document Type and Number:
Japanese Patent JP2020142152
Kind Code:
A
Abstract:
To provide an apparatus, systems and methods for mapping of tissue oxygenation.SOLUTION: An apparatus, systems and methods are provided that generate in vivo maps of oxygenation measurement of biological tissue. These may include surgical instruments and stand-alone imaging systems with incorporated oxygen sensing capability. Oxygenation maps can be determined via fluorescent or phosphorescent lifetime imaging of an injectable probe with an oxygen-dependent optical response. A probe configuration and methods and an apparatus of injecting the probe into the tissue are provided. Methods and an apparatus for temperature compensation of temperature-dependent lifetime measurement are provided to improve oxygenation measurement accuracy. Oxygen maps may be registered with visible light images to assist in assessing tissue viability or localize anomalies in the tissue.SELECTED DRAWING: Figure 1
