Abstract :
4D stereo X-ray imaging is realized as the sequence of 3D stereo images in some period of time. Data for 4D stereo can be received on tomosynthesis, linear tomography or cone beam tomography units. Majority of computed tomography systems don´t suits for 4D because of motion artifacts caused by organ´s deformation during data collecting. Organ´s movement causes geometrical measuring errors in 3D and 4D imaging. But such errors can be predicted and corrected. Correction of motion errors is based on predicted Z coordinate value for next stereo image and calculated value from acquired image.
