  • Using augmented reality in surgical navigation
    Patent number: 11883118
    Abstract: A surgical navigation system may include a processor and a display. The processor may receive a patient image and sensor data captured by a sensor, receive a medical image, generate a hologram of the medical image, perform coregistration between the patient image and the hologram, superimpose the hologram on the patient image, and display the superimposed image. Coregistration may be performed manually via a user interaction, or automatically based on one or more fiducials in the medical image and sensor data related to the fiducials. The system may monitor a change in the environment and update the display correspondingly. For example, the system may monitor a movement of a body of the patient, monitor the size of an organ of the patient as the organ is being under operation, or a movement of the surgical instrument. The sensor may be an augmented reality (AR) sensor in an AR device.
