VTNE practice: Diagnostic Imaging Questions and answers What is a physical property of x-rays? - ANSWER-Travel in straight lines As the wavelength of x-ray photons shortens, the energy of the x-ray beam will - ANSWER-Increase The kVp setting on an x-ray machine controls the - ANSWER-Quality of the x-ray beam The milliampere-seconds (mAs) setting on an x-ray machine controls the - ANSWER-Quantity of x-rays emitted During an exposure, electrons in the x-ray tube travel from the - ANSWER-Ca...

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...
