Mobile radiography system and method for aligning mobile radiography system

A method for aligning a mobile radiography system including a radiation source and a detector, comprising:

• determining an angular difference between the radiation source and the detector;
• recognizing a position of the detector relative to the radiation source based on the angular difference between the radiation source and the detector;
• setting a priori model of the detector, producing a perspective transformation of the priori model of the detector based on the angular difference between the radiation source and the detector;
• comparing the perspective transformation with the position of the detector;
• and determining a center area of the detector;
• and
• aligning the radiation source and the detector based on the position of the detector and the angular difference between the radiation source and the detector.

A method for aligning a mobile radiography system including a radiation source and a detector, comprising:

• determining an angular difference between the radiation source and the detector;
• recognizing a position of the detector relative to the radiation source based on the angular difference between the radiation source and the detector;
• recognizing the position of the detector comprises capturing at least two spaced apart markers of the detector;
• obtaining a first distance between the at least two spaced apart markers captured by the positioning device, comparing the first distance with a second distance of the at least two spaced apart markers of a perspective transformation of a priori model of the detector based on the angular difference between the radiation source and the detector, determining a distance between the radiation source and the detector;
• and
• aligning the radiation source and the detector based on the position of the detector and the angular difference between the radiation source and the detector.
