Fifth generation of CT Scan.

The fifth generation of CT scan is a stationary / stationary system. Fifth generation of  CT scanner has been developed specifically for cardiac tomographic imaging. This “cine-CT” scanner does not use a conventional x-ray tube; instead, a large arc ( 210°)  of tungsten encircles the patient and lies directly opposite to the detector ring. It uses an electronic gun that deflects and focuses a fast moving electron beam along tungsten target ring in the gantry. Since the detector is also in the form of ring, it permits simultaneous acquisition of multiple image sections. The image are obtained in 50 ms  times and can produce fast frame rate CT movies of the beating heart. The hole heart can be acquired in 0.2 sec.
