摘要： The present invention is directed to a method of multi-motion compensation for high-quality cone-beam CT of the head. A multi-stage approach is incorporated that includes a pre-conditioning stage in which an initial estimation of the motion trajectory is obtained with 3D-2D registration using the motion-contaminated CBCT and projection data. In the present invention, the motion-contaminated CBCT is used as a basis for 3D-2D registration in the pre-conditioning stage to capture large amplitude, rapid movements of the head and provide better initialization of the autofocus solution.

摘要： This disclosure provides systems, methods, and devices for image signal processing detect and correct motion during HDR fusion. In a first aspect, a method is provided that includes receiving a first image frame, a second image frame, and a third image frame. The second image frame may be captured with a short exposure time and the third image frame may be captured with a long exposure time. The method may include determining a first motion map based on the first and third image frames and a second motion map based on the second and third image frames. A third motion map may be determined based on the first and second motion maps and used to determine a fourth image frame by combining the second and third image frames. Other aspects and features are also claimed and described.
