Abstract
Provided is a method of correcting a medical image according to a patient's pose variation. The method includes attaching a marker to an object, generating a first non-real-time image and a first real-time image when the object is in a first pose, generating a second real-time image when the object is in a second pose, and correcting the first non-real-time image based on shift information of the marker when the object is changed from the first pose to the second pose.
Claims25
An image correcting method comprising:
- attaching a marker to an object, and generating a first non-real-time image and a first real-time image including the object's anatomical information about a surrounding region including a position of the marker when the object is in a first pose;
- generating a second real-time image of the object about the surrounding region when the object is in a second pose;
- obtaining shift information of the marker based on the first real-time image and the second real-time image when the object is changed from the first pose to the second pose;
- and
- correcting the first non-real-time image based on the shift information of the marker.
An image correcting apparatus comprising:
- a first image generating unit to generate a first non-real-time image including an object's anatomical information about a surrounding region including a position of a marker attached to the object when the object is in a first pose;
- a second image generating unit to generate a first real-time image including the object's anatomical information about the surrounding region when the object is in the first pose;
- a third image generating unit to generate a second real-time image of the object about the surrounding region when the object is in a second pose;
- a shift information obtaining unit to obtain shift information of the marker based on the first real-time image and the second real-time image when the object is changed from the first pose to the second pose;
- and
- an image correcting unit to correct the first non-real-time image based on the shift information of the marker.
An image correcting system comprising:
- at least one imaging apparatus that generates a first non-real-time image, and first through third real-time images including anatomical information of an object to which a marker has been attached;
- and
- an image processing apparatus that obtains shift information of the marker using the first real-time image and the second real-time image of the object generated by the imaging apparatus, and corrects the first non-real-time image based on the shift information of the marker.
A method of measuring a distance between an imaging apparatus and an object, the method comprising:
- obtaining two or more images including the object;
- calculating a first distance between the imaging apparatus and the object by performing triangulation based on the two or more images;
- calculating a second distance between the imaging apparatus and the object after calibrating lenses and rectifying the two or more images;
- and
- compensating for a difference between the second distance and an actual distance between the imaging apparatus and the object by using the first distance and the second distance.
