Abstract
Simulation systems and methods may enable medical training. A manufacturing unit may receive data from a configuration unit indicating identification and manufacturing parameters for an anatomy model. A data processing unit may receive data from the configuration unit identifying the anatomy model, and data from a calibration unit indicating a position and/or orientation of a position and orientation sensor relative to the anatomy model. The data processing unit may also receive data from the position and orientation sensor indicating a position and/or orientation of the anatomy model. The data processing unit may generate a virtual image using the data from the position and orientation sensor, the data from the calibration unit, and the data from the configuration unit. The data processing unit may render the virtual image to a display.
Core Innovation
The invention relates to a simulation system and simulation method that generate and render a virtual reality (VR) model or an augmented reality (AR) model for medical simulation using an interchangeable anatomy model. The interchangeable anatomy model includes an anatomy model identification, and a position and orientation sensor is configured to attach to the interchangeable anatomy model. A calibration unit stores the anatomy model identification and calibration data associated with the position and orientation sensor and the interchangeable anatomy model.
In operation, the data processing unit receives the anatomy model identification from the calibration unit and identifies the interchangeable anatomy model based on the anatomy model identification. The data processing unit proposes a choice of simulation scenarios, where each simulation scenario includes a VR model or an AR model. After a user selects one simulation scenario, the data processing unit receives data from the position and orientation sensor indicating the position of the interchangeable anatomy model, the orientation of the interchangeable anatomy model, or a combination thereof, and receives calibration data indicating the position of the position and orientation sensor relative to the interchangeable anatomy model, the orientation relative to the interchangeable anatomy model, or a combination thereof.
The data processing unit then generates the VR model or AR model associated with the selected simulation scenario using the sensor data and the calibration data, and renders the generated VR model or AR model to a display. The interchangeable anatomy model can be manufactured with an integration site placeholder for attaching the position and orientation sensor, where the location of the integration site placeholder can be selected to provide sufficient material to include a mating shape.
Claims Coverage
Two independent claims are identified. Each independent claim is centered on using an anatomy model identification and associated calibration data to select and generate a VR/AR simulation scenario from live position and orientation sensor data and to render the selected VR/AR model to a display.
Interchangeable anatomy model identification and scenario-based VR/AR generation
A simulation system comprising a data processing unit and a display in communication with the data processing unit, an interchangeable anatomy model having an anatomy model identification, a position and orientation sensor configured to attach to the interchangeable anatomy model, and a calibration unit configured to store the anatomy model identification and calibration data associated with the position and orientation sensor and the interchangeable anatomy model; wherein the data processing unit receives the anatomy model identification from the calibration unit, identifies the interchangeable anatomy model and proposes a choice of simulation scenarios (each comprising a VR model or an AR model), receives a selection of one simulation scenario from a user, receives data from the position and orientation sensor indicating the position and/or orientation of the interchangeable anatomy model, receives the calibration data indicating the position and/or orientation of the position and orientation sensor relative to the interchangeable anatomy model, generates the VR model or AR model associated with the selected simulation scenario using the sensor data and calibration data, and renders the VR model or AR model to the display.
Calibration-data-based simulation method with VR/AR rendering
A simulation method comprising receiving, with a data processing unit, an anatomy model identification from a calibration unit; receiving, with the data processing unit, calibration data from the calibration unit, the calibration data indicating a position of a position and orientation sensor relative to an interchangeable anatomy model, an orientation of a position and orientation sensor relative to the interchangeable anatomy model, or a combination thereof; identifying, with the data processing unit, the interchangeable anatomy model based on the anatomy model identification and proposing a choice of simulation scenarios based on the identification, each simulation scenario comprising a VR model or an AR model; receiving, with the data processing unit, a selection of one of the simulation scenarios from a user; receiving, with the data processing unit, data from the position and orientation sensor indicating a position of the interchangeable anatomy model, an orientation of the interchangeable anatomy model, or a combination thereof; generating, with the data processing unit, the VR model or AR model associated with the selected simulation scenario using the data from the position and orientation sensor and the calibration data; and rendering, with the data processing unit, the VR model or AR model to a display.
Across both independent claims, the core coverage is the same: identify an interchangeable anatomy model using stored anatomy model identification, propose and receive selection of a VR/AR simulation scenario, combine live position/orientation sensor data with calibration data that defines the sensor relationship to the anatomy model, then generate and render the selected VR/AR model to a display.
