  • Patent number: 11410305
    Abstract: Iterative material decomposition of multispectral image data includes providing a plurality of spectral images of a region of interest comprising a body part and a plurality of sets of material coefficients for a plurality of materials. Each spectral image is decomposed into a plurality of material images and an offset image. At least one of the material images for each spectral image is manipulated on the basis of at least one topological constraint relating to the body part to determine for each spectral image an updated plurality of material images and an updated offset image. A plurality of spectral images is then recomposed from the corresponding updated plurality of material images and the updated offset. Intensities at image locations are compared, and the updated plurality of material images is modified. The steps are repeated until convergence, and at least one of the recomposed spectral images at convergence is output.

  • Patent number: 11389245
    Abstract: There is provided a computer-implemented method (200) and apparatus for determining a transformation for anatomically aligning fragments of a broken bone. An image of the broken bone of the subject is acquired (202). The bone is broken into two or more fragments. A model of a corresponding unbroken bone and at least one parameter is acquired. The at least one parameter defines one or more deformations to the model that are permitted when fitting portions of the model of the unbroken bone to corresponding fragments of the broken bone (204). Portions of the model of the unbroken bone are fit to corresponding fragments of the broken bone based on the at least one parameter (206). A transformation is determined that anatomically aligns the fragments of the broken bone with the corresponding portions of the model (208).

  • Publication number: 20220175232
    Abstract: Method and related system for marker-based navigation. A first image is capturing (S530) with a medical imaging apparatus (ENDO), whilst a light source (LS1) of an implanted marker device (MD) is in a low intensity state and a second light source (LS2) of the medical imaging apparatus (IA) is in a high intensity state, higher than the low intensity state of the marker. A second image is captured (S560) with the medical imaging apparatus (ENDO), whilst the light source (LS1) of the implanted marker device is in a high intensity state and the second light source (LS2) of the medical imaging apparatus (IA) is in a low intensity state, lower than the high intensity state of the marker. The two images may then be combined to obtain a combined image that represents the location of the marker at high signal-to-noise-ratio.

  • Publication number: 20200342228
    Abstract: Augmented reality (AR) servicing guidance uses a mobile device (30, 90) with a display and a camera. Computer vision (CV) processing (102) such as Simultaneous Location and Mapping (SLAM) is performed to align AR content (80) with a live video feed (96) captured by the camera. The aligned AR content is displayed on the display of the mobile device. In one example, the mobile device is a head-up display (HUD) (90) with a transparent display (92, 94) and camera (20). In another example the mobile device is a cellphone or tablet computer (30) with a front display (34) and a rear-facing camera (36). The AR content (80) is generated by CV processing (54) to align (70) AR content with recorded video (40) of a service call. The aligning (72) includes aligning locations of interest (LOIs) identified in the recorded video of the service call by a user input.
