  • Patent number: 10390726
    Abstract: A method of visualizing spinal nerves includes receiving a 3D image volume depicting a spinal cord and a plurality of spinal nerves. For each spinal nerve, a 2D spinal nerve image is generated by defining a surface within the 3D volume comprising the spinal nerve. The surface is curved such that it passes through the spinal cord while encompassing the spinal nerve. Then, the 2D spinal nerve images are generated based on voxels on the surface included in the 3D volume. A visualization of the 2D spinal images is presented in a graphical user interface that allows each 2D spinal image to be viewed simultaneously.

  • Patent number: 10376148
    Abstract: A fluorescence imaging device detects fluorescence in parts of the visible and invisible spectrum, and projects the fluorescence image directly on the human body, as well as on a monitor, with improved sensitivity, video frame rate and depth of focus, and enhanced capabilities of detecting distribution and properties of multiple fluorophores. Direct projection of three-dimensional visible representations of florescence on three-dimensional body areas advantageously permits view of it during surgical procedures, including during cancer removal, reconstructive surgery and wound care, etc. A NIR laser and a human visible laser (HVL) are aligned coaxially and scanned over the operating field of view. When the NIR laser passes over the area where the florescent dye is present, it energizes the dye which emits at a shifted NIR frequency detected by a photo diode. The HVL is turned on when emission is detected, providing visual indication of those positions.

  • Patent number: 10342464
    Abstract: Systems and methods employing a depth-sensing camera to detect abdomen rise and fall during an infant sleep period, or lack thereof due to respiratory arrest. Visual processing of image data collected by one or more 3D digital camera is performed to detect the infant and to measure a distance between an infant's abdominal cavity and a camera baseline over time. An alarm may be triggered at by the system, locally and/or at remote devices, such as a mobile phone, tablet, laptop, etc. The monitoring system may also detect situations when an infant rolls from a back-sleeping to a belly-sleeping position.

  • Patent number: 10335120
    Abstract: The present invention relates to an ultrasound imaging system and a method for the measurement of a distance (58) between two points (54, 56) within a volume of a three-dimensional image (50). To avoid the commonly known fore-shortening effect, according to which a distance measured by the system is shorter than an actual distance (58) between the two points (54, 56), an in-depth control of a cursor (53) shown in the image (50) on the display as provided to the user. Further, an indication (72) may be given to the user that the cursor (53) collides with a structure (52) within the volume to allow the user to assess the movement of the cursor out of the plane shown on the display more conveniently. By this, occurrence of the fore-shortening effect may be avoided.

  • Patent number: 10325176
    Abstract: A method of assessing the quality of an retinal image (such as a fundus image) includes selecting at least one region of interest within a retinal image corresponding to a particular structure of the eye (e.g. the optic disc or the macula), and a quality score is calculated in respect of the, or each, region-of-interest. Each region of interest is typically one associated with pathology, as the optic disc and the macula are. Optionally, a quality score may be calculated also in respect of the eye as a whole (i.e. over the entire image, if the entire image corresponds to the retina).

  • Patent number: 10307057
    Abstract: An eye imaging apparatus includes a lighting device including a fundus illuminator and a cornea illuminator; a half mirror; an imaging device including a camera having a first objective lens; and a first polarizer. The first polarizer is disposed between the half mirror and the camera. The fundus illuminator irradiates the half mirror with first light polarized in a direction orthogonal to a transmission axis of the first polarizer. The half mirror receives the first light and outputs resulting light to an eye. A travel direction of the resulting light is in alignment with an optical axis of the first objective lens. The cornea illuminator emits light at a timing different from an emission timing of the first light, and the eye is irradiated with second light based on the light emitted by the cornea illuminator from a direction different from a direction parallel with the optical axis.
