  • Publication number: 20200093544
    Abstract: A system and method for registration and coordinated manipulation of augmented reality image components includes registering a model of patient anatomy to a first image of the patient anatomy captured using an imaging device to determine a baseline relationship between the model and the first image, tracking movement of a computer-assisted device used to manipulate the imaging device, updating the baseline relationship based on the tracked movement, and generating a composite image by overlaying the model on a second image of the patient anatomy according to the updated relationship. In some embodiments, the model is semi-transparent. In some embodiments, registering the model to the first image includes adjusting the model relative to the first image based on one or more inputs received from a user and generating a model to image transformation based on the adjustments to the model.

  • Patent number: 10376335
    Abstract: In a method and an apparatus to provide updated images during a robotically-implemented surgical procedure, 3D data is obtained of a volume of a patient, which includes anatomy involved in the procedure. The anatomy is segmented from a reconstructed image of the volume. During the procedure, the surgeon applies forces on the anatomy, causing a geometric change of the anatomy. Force sensors in the surgical robot detect these forces, which are supplied to a processor that controls display of the segmented anatomy at a display screen. From the applied forces and the physical properties of the anatomy, the processor calculates the geometric change of the anatomy that has occurred and modifies the appearance and/or position of the displayed segmented anatomy on the display screen in real time during the procedure, so as to visualize the geometric change.
