SYSTEMS AND METHODS FOR DETERMINING TIMING FOR FLUORESCENCE BASED BLOOD FLOW ASSESSMENT

A method for performing an assessment related to blood flow in tissue includes receiving fluorescence imaging data associated with movement of a fluorescence imaging agent through a target, determining at least one characteristic associated with a current stage of the movement of the fluorescence imaging agent through the target based on the fluorescence imaging data, comparing the at least one characteristic associated with the current stage to predefined criteria to determine whether the current stage corresponds to a suitable stage for performing an assessment related to blood flow; and, in accordance with the current stage corresponding to the suitable stage, performing the assessment related to blood flow in at least a portion of the target based on the fluorescence imaging data.

Fluorescence imaging processing and computation for surgery

Methods for dynamically evaluating blood flow are provided. The method may include injecting Indocyanine Green (ICG) into the bloodstream of a patient, such that the ICG perfuses into a tissue of the patient. ICG images of the tissue may be recorded and stored, such that a user may select a range of stored ICG images. Data indicative of the selected range of stored ICG images is automatically normalized and background-filtering, and a dynamic representation of the ICG perfusion may be generated as a function of time based on the normalized and filtered data. As such, a clinical decision may be made based on the dynamic representation of the ICG perfusion.

DEVICES AND METHODS FOR VASCULAR NAVIGATION, ASSESSMENT AND/OR DIAGNOSIS

Devices and methods for vascular navigation, assessment and/or diagnosis are described which determine the location of the tip of a vascular catheter using the introduction of a medium with a measurable parameter (e.g., temperature, light reflection, sound reflection, etc.) and sensing and measuring the measurable parameter as the catheter is advanced. Measurements of the parameter are tracked over time, recorded and analyzed. The value of the parameter and/or the shape of the parameter value vs. time curve may be used in the analysis. For example, curve amplitude, variability, standard deviation, slope, etc. may be used in the analysis of catheter location.
