Abstract
An apparatus for use with a medical system, the medical system comprising a medical device configured to treat and/or image a patient, includes: a camera configured to capture an image of a first mirror, wherein the image of the first mirror contains an image of at least a part of the patient and/or an image of at least a part of the medical system; wherein the camera comprises electronics that are not radiation-hard.
Claims17
An apparatus for use with a medical system, the medical system comprising a medical device configured to at least one of treat a patient or image the patient, the apparatus comprising:
- a camera configured to capture an image of a first mirror;
- and
- a processor configured to receive an image frame comprising the image of the first mirror from the camera and remove a part of the image frame that does not contain the image of the first mirror,
- wherein the image of the first mirror contains at least one of an image of at least a part of the patient or an image of at least a part of the medical system.
An apparatus for use with a medical system, the medical system comprising a medical device configured to at least one of treat a patient or image the patient, the apparatus comprising:
- a camera configured to capture an image of a first mirror, wherein the image of the first mirror contains at least one of an image of at least a part of the patient or an image of at least a part of the medical system;
- and
- a processor configured to receive an image frame from the camera, the image frame comprising the image of the first mirror,
- wherein the processor is also configured to remove a part of the image frame that does not contain the image of the first mirror, extract the image of the first mirror from the image frame, and process the image of the first mirror to monitor a position of the patient, to monitor a physiological state of the patient, to monitor a position of a component of the medical system, to prevent a collision between the medical device and the patient, to prevent a collision between the medical device and a patient support, or any combination of the foregoing.
A method performed by an apparatus that is configured for use with a medical system, the medical system comprising a medical device configured to at least one of treat a patient or image the patient, the method comprising:
- capturing an image of a first mirror, wherein the image of the first mirror contains at least one of an image of at least a part of the patient or an image of at least a part of the medical system;
- receiving an image frame comprising the image of the first mirror;
- removing a part of the image frame that does not contain the image of the first mirror;
- and
- processing the image of the first mirror to monitor a position of the patient, to monitor a physiological state of the patient, to monitor a position of a component of the medical system, to prevent a collision between the medical device and the patient, to prevent a collision between the medical device and a patient support, or any combination of the foregoing.
