  • Publication number: 20230050857
    Abstract: An exemplary object masking system is configured to mask a recognized object during an application of a synthetic element to an original image. For example, the object masking system accesses a model of a recognized object depicted in an original image of a scene. The object masking system associates the model with the recognized object. The object masking system then generates presentation data for use by a presentation system to present an augmented version of the original image in which a synthetic element added to the original image is, based on the model as associated with the recognized object, prevented from occluding at least a portion of the recognized object. In this way, the synthetic element is made to appear as if located behind the recognized object. Corresponding systems and methods are also disclosed.

  • Publication number: 20220414914
    Abstract: An exemplary tissue volume detection system accesses, during a surgical procedure involving resecting a piece of tissue from a body, a plurality of depth datasets for the resected piece of tissue. Each of the plurality of depth datasets is captured as a different portion of a surface of the resected piece of tissue is presented to an imaging device by an instrument that holds the resected piece of tissue in a manner that sequentially presents the different portions of the surface to the imaging device. During the surgical procedure and based on the depth datasets, the system generates a three-dimensional (3D) occupancy map that includes a set of voxels identified to be occupied by the resected piece of tissue. Based on the 3D occupancy map and still during the surgical procedure, the system determines an estimated volume of the resected piece of tissue. Corresponding systems and methods are also disclosed.

  • Publication number: 20220323157
    Abstract: A medical system includes one or more processors. The processors are configured to perform operations including receiving image data associated with an anatomic feature from a first imaging device. The image data is associated with a first imaging device space. Probe data associated with the anatomic feature is obtained from a second imaging device. The probe data is associated with a second imaging device space. The probe data is registered to the image data to generate a first registration between the second imaging device space and the first imaging device space. Anatomic model associated with the anatomic feature is registered to the probe data to generate a second registration between a model space of the anatomic model and the second imaging device space. A third registration between the model space and the first imaging device space is generated based on the first registration and the second registration.

  • Publication number: 20220286801
    Abstract: System and method for projecting audio signals to an operator of a teleoperational surgical system to convey spatial orientation associated with the audio signals to the operator. Characteristics of the audio signals such as direction and volume may be selected to give the impression that the remote operator is positioned locally next to the patient. Characteristics of the audio signals may also be modified to provide spatial translations between actual locations of audio sources within a physical audio environment and simulations locations of the audio sources with a virtual audio environment.
