High frequency generator circuit

The electron energy, in turn, depends directly on the accelerating voltage; thus, doubling the voltage would increase total x-ray yield by a factor of four. … In any event, the voltage is very important since it determines the energies of the bremsstrahlung photons and strongly affects x-ray yield.

X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 10 16 to 10 20 hertz (Hz) .

Computed tomography (CT), fluoroscopy, and radiography (“conventional X-ray” including mammography) all use ionizing radiation to generate images of the body.
