Abstract
A computed tomography system with an adjustable focal spot-to-detector distance has a gantry provided with a patient opening, an x-ray tube and a detector, respectively mounted at opposite sides of the gantry. The x-ray tube has a focal spot and the x-ray fan beam radiated from the focal spot exhibits a fixed aperture angle. The x-ray tube is installed on a linear track and can be moved along the rail of the linear track.
Claims10
A computed tomography system comprising:
- a gantry having a patient opening therein;
- an x-ray tube and a detector mounted opposite each other at said gantry, said x-ray tube having a focal spot from which x-ray radiation is emitted with a fixed aperture angle;
- and
- said x-ray tube being mounted at said gantry on a linear track having a rail, and being moveable along said rail of said linear track to selectively adjust a distance between said focal spot and said detector.
