X-rays: Typical diagnostic wavelength and photon energy range. - Answer-100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - Answer-A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation i...

The anode includes the: - Answer-target and induction motor the cathode includes the: - Answer-Filaments and focusing cup the motor that turns the anode operates through what? - Answer-mutual induction with a rotating anode, the focal spot becomes a: - Answer-Track the focusing cup is able to keep the electrons together because of what? - Answer-like charges repel The stator is made up of electromagnets? - Answer-True prepping the rotor but not making an exposure on a regular b...
