Medical x-ray recording system i.e. biplane x-ray system, for recording image of e.g. catheter in patient body during percutaneous transluminal coronary angioplasty, has x-ray emitter arranged at holder at distance from another emitter

摘要

The system has an adjustable holder with a main x-ray emitter (10) and an x-ray detector (11) arranged at opposite sides, and another x-ray emitter (12) arranged at the holder at a distance from the former x-ray emitter, where the holder is formed by a C-arm (26). The latter x-ray emitter is arranged around an extension angle of 10 degrees along the C-arm, and the holder is fastened at a robot arm. The latter x-ray emitter is formed by field emission radiators with field emission cathodes that exhibit nanostructured material with carbon nanotubes. An independent claim is also included for a method for recording x-ray of an examination object.
