Patent ID: 7421061

Claim:
A method of compensating for patient motion when recording a series of medical images consisting of 2D medical images, wherein the medical images consisting of 2D medical images of an examination area of a patient are recorded at specific time intervals using an imaging system and are correlated with each other, and a current spatial position of the examination area is determined relative to a frame of reference assigned to the imaging system, by a localization system, the method comprising: determining a first spatial position of the examination area substantially in parallel with recording a first medical image consisting of 2D medical image of the series; recording farther medical images consisting of 2D medical images of the series; continuously determining the current spatial position of the examination area for each current recorded further medical image consisting of 2D medical image, by the localization system while recording the series of medical images consisting of 2D medical images; determining a difference between each current and the first spatial positions based on the each current recorded farther medical image consisting of 2D medical image and the first medical image consisting of 2D medical image; and compensating the difference on the each current recorded further medical image consisting of 2D medical image by adjusting the imaging system such that the first and further medical images consisting of 2D medical images show the examination area in the same position and orientation.
