Question
1) The potential of the x-ray tube determines the number of electrons leaving the cathode the energy of the electrons impinging on the target the energy of the characteristic x-rays the minimum bremsstrahlung energy the maximum x-ray energy Submit Your submissions: ACDX Submitted: Wednesday, July 4 at 3:52 PM Feedback: 7) 10 attenuation in water total attenuation Compton scattering 0.01 photoelectric effect pair production 0.001 10 100 1000 10000 100000 photon energy (kev) The graph above shows the different attenuation mechanisms that take place in water over a range of x-ray energies. Choose which statements below correctly pertain to the attenuation of x-rays in matter Low energy photons are more likely to be absorbed. Images made with photons in the diagnostic range of 100 keV would be better quality because scattering is not Several absorption edges appear in the graph above O If using lower energy photons, the anode current should be increased to make up for increased absorption If using lower energy photons, the kVp should be increased to increase photon intensity SubmitExplanation / Answer
1) The potential of the X ray tube determines (2nd option) the energy of the electrons impinging on the target. because more potential difference more kinetic energy.
7) From the graph above
Low energy photons are moe likely to be absorbed.
If using low energy photons,the anode current should be increased to make up for increased absorption.Because more anode current more no of photons and more intensity.
