Abstract: A method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel, the method including displaying on a graphical user interface (GUI) an image including detected results of lumen borders and at least one stent, the image including an evaluated stent expansion and an evaluated stent apposition determined from the intravascular image. The method also includes determining whether a modification to the detected results of the stent has been received by the GUI. Then, re-evaluating stent length, stent expansion and stent apposition when it is determined that the detected results of the stent has been modified via the GUI and displaying the re-evaluated stent expansion and the re-evaluated stent apposition on the GUI.

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 α formed between the normal to the sample surface and the optical axis of the excitation light. A processor calculates the angle α 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(α). The calibration factor g(α) is a function of the angle α calculated at two or more of the plurality of locations. The angle α is composed of a transversal angle αt and an axial angle αa.

Abstract: Methods, apparatuses, systems, and storage mediums for correcting distortion of a spectrally encoded endoscopy (SEE) image are provided. A first reference pattern comprising a plurality of radial lines is scanned with an SEE spectral line to obtain a first image. Signs of a tangential shift and/or of a radial shift of the spectral line may be determined, and magnitudes of the tangential shift and of the radial shift may be computed. A second reference pattern comprising at least a circle with the SEE spectral line may be scanned to obtain a second image in a case where the radial shift is positive. The magnitude of the radial shift may be computed based on the magnitude of the tangential shift and a radius of the circle. The tangential shift and the radial shift may then be applied for correcting distortion.

Abstract: Systems, methods, and computer-readable media are provided. Some embodiments include receiving, at a computing system from an image processing device, a request to access a resource. The computing system obtains information that identifies a component installed on the image processing device as a replacement component. The computing system obtains information indicating a count value of a counter associated with the component. The computing system determines whether the counter has been reset based on the information indicating the count value of the counter. In response to determining that the counter has not been reset, the computing system sends, to the image processing device, the resource including information for presentation as an interface element in a graphical user interface on a display of the image processing device, the interface element enabling a user to reset the counter by selecting the interface element.

Abstract: Gradient index lenses, or GRIN lenses, are useful for collimating light from a waveguide and reducing loss when coupling two fibers or coupling the fiber to other optical components. There is provided herein a method to align a GRIN lens to the distal end of an optical fiber with precise lateral alignment. The alignment occurs by: (1) rotating the fiber with respect to the lens so that the fiber is parallel with the lens, such that a light is transmitted through the fiber and then through the lens, and (2) translating the fiber laterally with respect to the lens based on the position of a circle pattern that appears on the screen after the distal end of the lens. The transmitted light is centered in the circle pattern for centered alignment or positioned at calculate distance from the center of the circle pattern for off-axis alignment.
