  • Patent number: 11911139
    Abstract: The present disclosure relates to a system and a method for automatically measuring and assessing hemodynamics in tissue of an anatomical structure of a subject. In particular the present disclosure relates to continuously measuring and assessing hemodynamics in medical procedures using fluorescence imaging and wherein the administration of the fluorescent agent is controlled and automated. One aspect relates to a method of automatic perfusion assessment of an anatomical structure of a subject, the method comprising administration into a vein of a bolus corresponding to less than 0.005 mg ICG/kg body weight of a first fluorescence imaging agent.

  • Publication number: 20230035705
    Abstract: A system and a method is disclosed for continuously identifying blood vessels in tissue during fluorescence imaging. Continuously measuring and assessing hemodynamics in tissue in medical procedures using fluorescence imaging may include the administration of the fluorescent agent that is controlled and automated and thereby identifying, mapping and visualizing blood vessels in the tissue. One embodiment relates a computer implemented method for identifying blood vessels in tissue of a subject, e.g. during a medical procedure, the method including the steps of continuously acquiring fluorescence images of the tissue wherein a fluorescent signal is oscillating with a predetermined pattern, and analysing the fluorescence images and the associated oscillating signal thereby continuously identifying blood vessels in the tissue.

  • Patent number: 10912471
    Abstract: A system and a method for automatically and continuously measuring and assessing hemodynamics uses fluorescence imaging in which the fluorescent agent is controlled and automated. A method of automatic perfusion assessment of an anatomical structure of a subject includes administration into a vein of a bolus corresponding to less than 0.01 mg ICG/kg body weight of a first fluorescence imaging agent. A system for automatic perfusion assessment during a medical procedure includes a controllable injection pump for holding at least one first fluorescence imaging agent, the injection pump being configured for injecting a predefined amount of the first fluorescence imaging agent into the blood. The system is configured for receiving and analysing a time series of fluorescence images and determining at least one perfusion parameter based on the analysis.

  • Patent number: 10271750
    Abstract: A system is provided for measuring and assessing hemodynamics in an anatomical structure of a subject, along with a method for image processing hemodynamics in at least a part of an anatomical structure in video images acquired from a subject. The system and method relates to measuring and assessing hemodynamics in, around and near the surface, in particular the gastrointestinal wall, of the gastrointestinal tract of a subject. A method for image processing hemodynamics in at least a part of an anatomical structure in video images acquired from a subject may performing image analysis of at least one video sequence acquired after a fluorescent contrast agent has been supplied to the subject, calculating intensity values in one or more regions of interest based on the image analysis, and determining the perfusion slope of the flow of the fluorescent contrast agent through at least one of said regions of interest.
