ABSTRACT

X-ray generators are intelligent voltage step-up and current step-down electronics, delivering the required tube voltage for the generation of X-rays and other power. Radiologists often associate the “generator” with its user interface which often comprises a major part of the user interface of a general purpose X-ray system. Some implementations allow for many break-down events to occur per second before an exposure is aborted due to lack of adequate X-ray intensity. A bad X-ray tube may exhibit reasonable performance when attached to an intelligent generator. Since 2008, General Electric has marketed spectral sensitive X-ray imaging in computed tomography. Feed-back loops are essential for controlling tube voltage and tube current. The tube voltage determines the image contrast, whereas the tube current specifies the photon flux from the X-ray source. For cost reasons, legacy radiographic generators were often configured to serve two X-ray tubes.
