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.
Claims16
An image correcting method, comprising:
- attaching a marker to an object, and generating a first non-real-time image, of a first image type, and a first real-time image, of a second image type, 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 second image type, 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;
- correcting, in a processor, the first non-real-time image based on the shift information of the marker;
- and
- displaying the corrected first non-real-time image on a monitor;
- wherein the obtaining of the shift information of the marker comprises:
- determining a point at which a value measured in data included in the first real-time image exceeds a threshold value, and specifying a first pose relationship between the point and the marker;
- selecting a point, corresponding to the point determined in the first real-time image, on the second real-time image, and specifying a second pose relationship between the point selected on the second real-time image and the marker;
- and
- calculating a shift direction and a shift amount of the marker when the object is changed from the first pose to the second pose using the first pose relationship and the second pose relationship.
