  • Patent number: 11779779
    Abstract: An apparatus for controlling the angular direction of energy emitted from a plurality of energy delivery devices. The apparatus includes a plurality of rods, each rod mechanically coupled to one of the energy delivery devices, to a stationary plate, and to a moveable plate. The stationary plate includes holes that are configured to receive a portion of a first rotatable joint that is mechanically coupled to each rod. The moveable plate includes holes that are configured to receive a portion of a second rotatable joint, the second rotatable joint slidingly engaging a portion of the respective rod. The angle of each rod changes when the moveable plate is moved in any direction with respect to the stationary plate. Changing the rod angle changes the angular direction of the energy emitted from the energy delivery devices such that the energy passes through an intended focal position.

  • Patent number: 11751971
    Abstract: An imaging and display system for guiding medical interventions includes a wearable display, such as a goggle display, for viewing by a user. The display presents a composite, or combined image that includes pre-operative surgical navigation images, intraoperative images, and in-vivo microscopy images or sensing data. The pre-operative images are acquired from scanners, such as MRI and CT scanners, while the intra-operative images are acquired in real-time from a camera system carried by the goggle display for imaging the patient being treated so as to acquire intraoperative images, such as fluorescence images. A probe, such as a microscopy probe or a sensing probe, is used to acquire in-vivo imaging/sensing data from the patient. Additionally, the intra-operative and in-vivo images are acquired using tracking and registration techniques to align them with the pre-operative image and the patient to form a composite image for display by the goggle display.

  • Patent number: 11748899
    Abstract: Machine learning is used to train a network to estimate a three-dimensional (3D) body surface and body regions of a patient from surface images of the patient. The estimated 3D body surface of the patient is used to determine an isocenter of the patient. The estimated body regions are used to generate heatmaps representing visible body region boundaries and unseen body region boundaries of the patient. The estimation of 3D body surfaces, the determined patient isocenter, and the estimated body region boundaries may assist in planning a medical scan, including automatic patient positioning.

  • Patent number: 11696685
    Abstract: A method for non-invasive quantification of organ fat using a magnetic resonance approach includes: constructing a detection system; connecting a detection area; detection system startup; acquiring data; analyzing data; and performing horizontal data analysis. An external computer, a radio frequency (RF) subsystem, and a portable magnet module are used to construct a system for non-invasive quantification of organ fat based on low-field nuclear magnetic resonance (LF-NMR), which causes no damage, and achieves accurate and non-invasive quantification of organ fat. Specific pulse sequences are used to excite nuclear spin in a target region to generate LF-NMR, so as to achieve “one-click” detection, which is used for fast screening of related diseases such as non-alcoholic fatty liver disease (NAFLD). The system has accurate quantification, and is easy to operate without constraints of operator qualifications.
