  • Patent number: 10602918
    Abstract: Still image display of a recent video image of tissue as a reference still image prior to a switch in the mode of illumination of the tissue. The still image is displayed concurrently with live video of the tissue under a different mode of illumination, to facilitate discrimination between healthy and diseased tissue. When a practitioner switches a light source from a “first light” to a “second light”, the second light video may be frozen/captured and displayed as a reference still image as a PIP, and the second light live video is displayed concurrently. The second light can be infrared and/or near infrared light. The second light can include structured light to project a structured light pattern to facilitate structure measurements. The second light source is configured with a numerical aperture greater than the first light source.

  • Patent number: 10602917
    Abstract: Still image display of a recent video image of tissue as a reference still image prior to a switch in the mode of illumination of the tissue. The still image is displayed concurrently with live video of the tissue under a different mode of illumination, to facilitate discrimination between healthy and diseased tissue, and further facilitate therapeutic intervention. The reference still image may be displayed either as an insert (picture-in-picture), side-by-side, or the like concurrently with the live video image. In some embodiments, when a practitioner switches a light source from “excitation-light” to “white light”, the “excitation-light” video may be frozen/captured and displayed as a reference still image as a PIP, and the “white-light” live video is displayed concurrently. When the source is switched again, the “white-light” video may be frozen/captured and displayed as a reference still image, and the “excitation-light” live video is displayed concurrently.

  • Patent number: 10470643
    Abstract: A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.

  • Patent number: 10448909
    Abstract: The invention relates to a combined imaging detector (110) for the detection of x-ray and gamma quanta. The combined imaging detector (110) is adapted for simultaneous detection of gamma and x-ray quanta. The combined imaging detector (110) includes an x-ray anti-scatter grid (111), a layer of x-ray scintillator elements (112), a first photodetector array (113), a layer of gamma scintillator elements (114), and a second photodetector array (115) that are arranged in a stacked configuration along a radiation-receiving direction (116). The x-ray anti-scatter grid (111) comprises a plurality of septa (117A, B, C) that define a plurality of apertures (118) which are configured to collimate both x-ray quanta and gamma quanta received from the radiation receiving direction (116) such that received gamma quanta are collimated only by the x-ray anti-scatter grid (111). The use of the x-ray anti-scatter grid as a collimator for received gamma quanta results in a significantly lighter combined imaging detector.
