  • Patent number: 10957045
    Abstract: Optimizations are provided for segmenting tissue objects included in an ultrasound image. Initially, raw pixel data is received. Here, each pixel corresponds to ultrasound information. This raw pixel data is processed through a first fully convolutional network to generate a first segmentation label map. This first map includes a first set of objects that have been segmented into a coarse segmentation class. Then, this first map is processed through a second fully convolutional network to generate a second segmentation label map. This second map is processed using the raw pixel data as a base reference. Further, this second map includes a second set of objects that have been segmented into a fine segmentation class. Then, a contour optimization algorithm is applied to at least one of the second set of objects in order to refine that object's contour boundary.

    Abstract: A nuclear scanner includes an annular support structure (12) which supports a plurality of radiation detector units (14), each detector unit including crystals (52), tiles (66) containing an array of crystals, or modules (14) of tiles. The detector units define annular ranks of crystals, and the annular ranks of crystals define spaces between the ranks. In another embodiment, the crystals define axial spaces between crystals. Separate rings of crystals have axial spaces that are staggered such that no area of the imaging region is missed. The spaces between the detector units may be adjusted to form uniform or non-uniform spacing. Moving the patient through the annular support structure compensates for reduced sampling under the spaces between ranks.

  • Patent number: 10751016
    Abstract: The quality of thoracic X-rays is depends on the inspiration state of an imaged patient. If the lungs of a patient are not significantly inflated during a thoracic X-ray, tissue from surrounding organs can cause the image to become cloudier, and the lung parenchyma is not effectively shown. Thus, there is a reliance on a medical professional to ensure that the patient is in an appropriate posture and inspiration state at the point of image exposure. This can be difficult with patients suffering from chronic conditions, though. Therefore, this application discusses a means to assess the inspiration state using the position of rib bones, and the diaphragm line in the X-ray image. Thus, an accurate estimate of inspiration state can automatically be reported to a medical professional, before a patient leaves the examination room, allowing an X-ray to be retaken, if necessary.

A second X-ray image of a medical component introduced into the vascular tree is created as a component image. An intensity of the second X-ray image for an image area with the medical component is ascertained as a component intensity. A ratio of component intensity and vascular tree intensity is calculated, and an overlay image with the first and the second X-ray image is generated depending on the calculated ratio of the vascular mask intensity and the component intensity.
