| 英文摘要 | The patient motion can damage the quality of computed tomography images, which are typically acquired in cone-beam geometry. the rigid patient motion is characterized by six geometric parameters and are more challenging to correct than in fan-beam geometry. we extend our previous rigid patient motion correction method based on the principle of locally linear embedding (lle) from fan-beam to cone-beam geometry and accelerate the computational procedure with the graphics processing unit (gpu)-based all scale tomographic reconstruction antwerp toolbox. the major merit of our method is that we need neither fiducial markers nor motion-tracking devices. the numerical and experimental studies show that the lle-based patient motion correction is capable of calibrating the six parameters of the patient motion simultaneously, reducing patient motion artifacts significantly.
