Calibration system and method for x-ray geometry |
摘要 |
A system for X-ray geometry calibration comprises a calibration frame adapted for mounting proximate to at least a portion of a patient's body, such as a patient's head. An X-ray source cooperates with a target at a given orientation and distance from the portion of a patient's body for forming an image of the portion of a patient's body and of at least an associated portion of the calibration frame. The calibration frame includes encoding arrangement for uniquely determining correspondence between the image of the associated portion of the calibration frame and the calibration frame such that the orientation and distance can be determined uniquely from the image of the associated portion of the calibration frame.
