Abstract

The present invention relates to a method for tracking the motion of a subject in real time and for correcting a medical image. The method includes the steps of: (a) a motion detection module outputting real-time motion information of a subject; (b) a motion calculation module receiving and analyzing the real-time motion information, transforming the analyzed result into triaxial motion parameters, and outputting the triaxial motion parameters; (c) a driving module driving a driving motor in response to the triaxial motion parameters; and (d) a medical image data acquisition module moving by as much as the subject moves in response to the driving of the driving motor. According to the present invention, medical image data can be acquired as if a subject has not moved during imaging by calculating the triaxial motion parameters of a subject through motion information acquired from the motion detection module and moving the medical image data acquisition module according to the triaxial motion parameters. Therefore, the acquisition of an erroneous sample due to the movement of the subject can be minimized, and the precision of the medical image can be improved by simultaneously moving the medical image data acquisition module in real time according to the movement of the subject.
