  • Patent number: 11883149
    Abstract: Apparatus and methods are described including a processor (20) configured to receive first and second sets of extraluminal images of a lumen, the second set being acquired while an endoluminal device is being moved through the lumen. The processor designates at least one of the first set of images as a roadmap image, and designates, within the lumen in the roadmap image, a roadmap pathway (42). A plurality of features (44, 46, 48, 50) that are visible within at least some of the second set of extraluminal images are identified, and an arrangement of three or more of the features within the image are compared to a shape of at least a portion of the roadmap pathway. Based upon the comparing, the identified features are mapped to locations along the roadmap pathway within the roadmap image. Other applications are also described.

  • Patent number: 11872163
    Abstract: A magnetic positioning system and related method for automated or assisted eye-docking in ophthalmic surgery. The system includes a magnetic field sensing system on a laser head and a magnet on a patient interface to be mounted on the patient's eye. The magnetic field sensing system includes four magnetic field sensors located on a horizontal plane for detecting the magnetic field of the magnet, where one pair of sensors are located along the X direction at equal distances from the optical axis of the laser head and another pair are located along the Y direction at equal distances from the optical axis. Based on relative magnitudes of the magnetic field detected by each pair of sensors, the magnetic field sensing system determines whether the patient interface is centered on the optical axis. The system controls the laser head to move toward the patient interface until the latter is centered on the optical axis.

  • Patent number: 11744646
    Abstract: Tools used within a surgical area may be equipped with sensors that allow them to be tracked within the magnetic field of an image guided surgery (IGS) system. The IGS system may be configured to detect various movement patterns of the tools, which may be mapped to and associated with corresponding actions or inputs to the IGS system. In one example, a registration probe may be moved along the x-axis and y-axis, with detected movements identified and received by the IGS system as movements of a mouse cursor on a display of the IGS system. In another example, the registration probe may be moved in a circular pattern, or quickly moved along any of the x-axis, y-axis, or z-axis, with each being configured to cause the IGS system to zoom a display, change a view, record video, or other actions.

  • Patent number: 11750377
    Abstract: Disclosed is a multi-source encrypted image retrieval method based on federated learning and secret sharing, including the following steps: S1. performing model training on a convolutional neural network of double cloud platforms based on federated learning, with an image owner joining the double cloud platforms as a coalition member; and S2. completing, by an authorized user, encrypted image retrieval based on additive secret sharing with the assistance of the double cloud platforms. The present disclosure provides a multi-source encrypted retrieval scheme based on federated learning and secret sharing, which simplifies the neural network model structure for retrieval by using federated learning, to obtain better network parameters. Better neural network parameters and a more simplified network model structure are achieved by compromising overheads on the image owner side, such that a better convolutional neural network can be used in encrypted image retrieval.

  • Patent number: 11737742
    Abstract: Devices, apparatus and methods for patient-specific MIS procedures. A patient-specific, MIS navigation guide device may include a main body having a proximal surface and a distal surface, wherein the distal surface is configured to face target tissue upon placement of said MIS navigation guide device. Anchors extend distally of the distal surface, and distal ends of the anchors lie on a three dimensional surface that matches contours of the target tissue in locations where the anchors are designed to contact. A position indicator on the device is interpretable by a surgeon to know when the anchors have not yet been contacted to the target tissue in a predetermined orientation and to know when the anchors have been contacted to the target tissue in the predetermined orientation.

    Abstract: A transponder includes an encapsulant defining a cavity having a spherical internal profile. A suspension medium and a core are contained within the cavity. The core includes a rod having a first end and a second end, and defines a longitudinal axis between the first end and the second end. The longitudinal axis of the rod defines an axis of sensitivity of the transponder, and the core defines a center of gravity closer to the second end of the rod as compared to the first end of the rod. The center of gravity is disposed along the longitudinal axis of the rod. The transducer includes a conductive coil wrapped around the rod, and a capacitor coupled to the conductive coil. The core self-orients itself such that the axis of sensitivity of the transponder is parallel with a plumb to gravity axis.

  • Patent number: 11726585
    Abstract: Circuits for controlling magnetic-based tracking systems are described. These systems may be used in virtual reality applications, for example to track in real-time the location of one or more body parts. The systems use a beacon emitting mutually orthogonal magnetic fields. On the receiver side, one or more sensors disposed on different parts of a body receive the magnetic fields. The beacon includes switching amplifiers for driving the magnetic field emitters. Being binary, these amplifiers may be controlled by binary signals. The circuits may exhibit a resonant frequency response, and may be operated off-resonance, thus providing for a better control of the magnetic fields amplitude. As a result, however, fluctuations in the envelop of the magnetic fields due to the presence of a beating tone may arise. These fluctuations may be shortened by gradually activating the drivers for the magnetic field emitters.

  • Patent number: 11701090
    Abstract: A workflow is disclosed to accurately register ultrasound imaging to co-modality imaging. The ultrasound imaging is segmented with a convolutional neural network to detect a surface of the object. The ultrasound imaging is calibrated to reflect a variation in propagation speed of the ultrasound waves through the object by minimizing a cost function that sums the differences between the first and second steered frames, and compares the first and second steered frames of the ultrasound imaging with a third frame of the ultrasound imaging that is angled between the first and second steered frames. The ultrasound imaging is temporarily calibrated with respect to a tracking coordinate system by creating a point cloud of the surface and calculating a set of projection values of the point cloud to a vector. The ultrasound imaging, segmented and calibrated, is automatically registered to the co-modality imagine.
