  • Patent number: 11172831
    Abstract: The invention generally relates to medical imaging systems that instantly and/or automatically detect borders. Embodiments of the invention provide an imaging system that automatically detects a border at a location within a vessel in response only to navigational input moving the image to that location. In some embodiments, systems and methods of the invention operate such that when a doctor moves an imaging catheter to a new location with in tissue, the system essentially instantly finds, and optionally displays, the border(s), calculates an occlusion, or both.

  • Patent number: 11147453
    Abstract: A multimodality system includes first and second modalities, a catheter, and a processor. The catheter collects fluorescent light from a plurality of locations of a sample which has been irradiated with excitation light of the second modality; a detector detects intensity of the fluorescent light received from the plurality of locations as a function of an angle ? formed between the normal to the sample surface and the optical axis of the excitation light. A processor calculates the angle ? at each of the plurality of locations based on radiation of the first modality incident on the sample, and corrects the intensity of the detected fluorescent light using a calibration factor g(?). The calibration factor g(?) is a function of the angle ? calculated at two or more of the plurality of locations. The angle ? is composed of a transversal angle ?t and an axial angle ?a.
