  • Publication number: 20240188796
    Abstract: An apparatus for processing image data of tissue that includes at least one processor is disclosed. The apparatus is configured for determining a profile from a plurality of profiles, and applying a plurality of settings from the determined profile. The apparatus determines the image based on the applied settings, and outputs data for displaying at least one image. Each profile includes a plurality of settings. Each profile can be configured to enhance and/or suppress anatomical features of the image.

  • Publication number: 20240194329
    Abstract: An apparatus for processing image data is disclosed. The apparatus includes one or more processors. The apparatus determines a feature in a cross-sectional image of a live tissue. The apparatus determines a superimposed image by superimposing a reference on the cross-sectional image or a subsequent cross-sectional image of the live tissue. The reference is based on the determined feature. An output interface outputs image data of the superimposed image for display.

  • Publication number: 20230404699
    Abstract: Examples relate to a system for a microscope system, to a microscope system comprising such a system, and to a corresponding method and computer program. The system comprises one or more processors and one or more storage devices. The system is configured to obtain a trigger signal. The trigger signal indicates a desire of a user of the microscope system to display a visual representation of a control functionality associated with an input device of the microscope system. The system is configured to generate, based on the trigger signal, a visual overlay comprising the visual representation. The system is configured to provide a display signal to a display device of the microscope system, the display signal comprising the visual overlay.

  • Publication number: 20230404700
    Abstract: Various aspects of the present disclosure relate to a surgical microscope system, and in particular, to an arm for a surgical microscope system. The surgical microscope system comprises an optics carrier comprising optical components of a microscope of the surgical microscope system. The surgical microscope system comprises a display device for displaying image data recorded by an optical imaging sensor of the surgical microscope system. The surgical microscope system comprises an arm. The arm comprises a first section and a second section. The first section is configured to provide a vertical and/or lateral adjustment of the position of the optics carrier. The second section is attached to a suspension point of the first section and to the optics carrier.

  • Publication number: 20230259003
    Abstract: An apparatus is disclosed which is to identify a feature of an image captured from a first focal plane; determining a focus position relative to the first focal plane; and to determine an aperture setting. At the focus position and the aperture setting, a depth of field is provided. The apparatus may be further configured to determine at least one of a second plane and a third plane relative to the first focal plane. At the focus position and the aperture setting, the at least one of the second plane or the third plane is in focus.

  • Publication number: 20230019054
    Abstract: Examples relate to a surgical microscope system, and to a system, a method and a computer program for a surgical microscope system. The system comprises one or more processors and one or more storage devices. The system is configured to obtain intraoperative sensor data of at least a portion of an eye from a Doppler-based imaging sensor of the surgical microscope system. The system is configured to process the intraoperative sensor data to determine information on a blood flow within the eye. The system is configured to generate a visualization of the blood flow. The system is configured to provide a display signal to a display device of the surgical microscope system based on the visualization of the blood flow within the eye.

  • Publication number: 20200390600
    Abstract: A surgical tool for shearing tissue at a target surgical site, the surgical tool comprising a cannula assembly with a distal end and a proximal end, a cannula opening into the lumen of the cannula at the distal end, a cutting device coupled to the distal end and within the cannula opening, and an axial ball joint coupled to the proximal end of the cannula assembly, that when rotated, causes the cutting device at the distal end to rotate about a longitudinal axis passing axially through the lumen of the cannula assembly, so as to shear a portion of tissue at a target surgical site.
