  • Publication number: 20210219944
    Abstract: In accordance with some embodiments, systems, methods, and media for automatically localizing and diagnosing thyroid nodules are provided. In some embodiments, a system for automatically diagnosing thyroid nodules comprises: an ultrasound machine; and a processor programmed to: receive a B-mode ultrasound of a thyroid from the ultrasound machine; provide the B-mode ultrasound to a classification model trained to automatically segment B-mode ultrasound; receive an output indicating which portions of the B-mode ultrasound correspond to a nodule; provide at least a portion of the B-mode ultrasound corresponding to the nodule to a second classification model trained to automatically classify thyroid nodules based B-mode, color Doppler, and shear wave elastography ultrasound; and receive, from the second trained classification model, an output indicative of the likelihood that the nodule is malignant.

  • Publication number: 20110191082
    Abstract: A cryoablation procedure at a surgery site is planned and simulated. One or more pre-procedure planning images of the surgery site are displayed on a user interface. Positioning of one or more virtual cryoprobes relative to the one or more pre-procedure planning images on the user interface is facilitated. Properties of the one or more virtual cryoprobes are selectable. Ice ball formation at the surgery site is then simulated based on the position and properties of the virtual cryoprobes. The simulated ice ball formation is based at least in part on tissue properties of the surgery site at each image unit of the one or more pre-procedure planning images. Boundaries of the simulated ice ball formation on the one or more pre-procedure planning images are then displayed.

  • Patent number: 7620442
    Abstract: A method for generating colonography images for colorectal screening of a patient. The patient is administered an amount of radiopaque stool marker which will enable stool present in the patient's colon to be distinguished from soft tissue. The patient's colon is imaged after the stool marker has been administered to generate colonography images. Preparation of the colon is simulated by processing the colonography images to remove marked stool before the images are observed during a diagnosis session.

  • Patent number: 5736625
    Abstract: A method is disclosed for preparing water soluble protein polymer conjugates which stabilize the protein so as to retain functional properties in a hostile environment. The method comprises covalently bonding the polymer to the protein through at least three linkers which linkers have three or more hydroxyl groups. The protein is conjugated at lysines or arginines.

  • Patent number: 5645809
    Abstract: A method of producing glassy carbon containing metal particles includes two steps. The first step is providing a metal complexed to a molecule which can cross-link to form glassy carbon. The molecule is heated so that the molecule cross-links to form glassy carbon containing metal particles. The glassy carbon can be incorporated into an electrode for use in an electrochemical cell.
