Abstract
Methods for an imaging system are provided. In some examples, a method includes determining an imaging field of view (FOV) of a rotatable imaging system, determining a size and/or shape of the imaging FOV and a position of the imaging FOV relative to the rotatable imaging system, determining a first location of the imaging FOV relative to an environment in which the rotatable imaging system is positioned, and sending information indicating the size and/or shape and the position of the imaging FOV as well as the first location of the imaging FOV relative to the environment to an external computing device.
Claims20
A method, comprising:
- determining an imaging field of view (FOV) of a rotatable imaging system, including a size and/or a shape of the imaging FOV of the rotatable imaging system and a position of the imaging FOV relative to the rotatable imaging system;
- determining a first location of the imaging FOV of the rotatable imaging system relative to an environment in which the rotatable imaging system is positioned;
- and
- sending information indicating the size and/or the shape and the position of the imaging FOV of the rotatable imaging system as well as the first location of the imaging FOV of the rotatable imaging system relative to the environment to an external computing device.
A cone-beam computed tomography (CBCT) imaging system, comprising:
- a rotatable gantry;
- an x-ray source and a detector mounted on the rotatable gantry;
- a processor;
- and
- a memory storing instructions executable by the processor to:
- determine an imaging field of view (FOV) of the CBCT imaging system, including a size and/or a shape of the imaging FOV of the CBCT imaging system and a position of the imaging FOV of the CBCT imaging system relative to the rotatable gantry;
- determine a first location of the imaging FOV of the CBCT imaging system relative to an environment in which the CBCT imaging system is positioned;
- send information indicating the size and/or the shape and the position of the imaging FOV of the CBCT imaging system as well as the first location of the imaging FOV of the CBCT imaging system relative to the environment to an external computing device;
- and
- responsive to a command to initiate image acquisition, activate the x-ray source and the detector, and rotate the rotatable gantry around a patient.
A method, comprising:
- determining, via a processor executing instructions stored in a memory of an imaging system, an imaging field of view (FOV) of the imaging system, the imaging system including an x-ray source and a detector mounted on a rotatable gantry, and the imaging FOV of the imaging system including a size and/or a shape of the imaging FOV and a position of the imaging FOV relative to the rotatable gantry;
- determining, via the processor executing the instructions stored in the memory of the imaging system, a first location of the rotatable gantry relative to an environment in which the imaging system is positioned;
- sending, from the imaging system, information indicating the size and the position of the imaging FOV of the imaging system as well as the first location to an augmented reality device;
- and
- displaying, on a see-through display of the augmented reality device, a graphical object, the graphical object sized and positioned on the see-through display based on the information received from the imaging system and a second location of the augmented reality device within the environment.
