Attenuation: a. is radiation that emerges from the patient b. describes changes in the x-ray beam as it travels through the patient c. produces only scatter radiation d. occurs only at doses used in radiation therapy - Answer Describes changes in the x-ray beam as it travels through the patient Which photon-tissue interaction makes radiography possible because of its creation of image contrast? a. Compton b. Coherent c. Photoelectric d. Pair production - Answer Photoelectric...

In order for an x-ray photon to be measured it must: 1. enter the detector chamber 2. be absorbed by the detector material 3. be converted to a measurable event correct answers 1,2,3 Which system component converts the projection attenuation data into the proper digital form for the array processor? correct answers analog-to-digital converter Which of the following is NOT a function of a PACS system? a. reconstruction of the image from the raw data b. long term data storage c. digita...

Photoelectric effect correct answers -When light of a sufficiently high frequency (typically blue to ultraviolet light) is incident on a metal in a vacuum, the metal atoms emit electrons. -albert einsteins 1905 explanation of the photoelectric effect won him the nobel prize. -Electrons liberated from the metal produce a current. -light beams of greater intensity produce larger current in this way. -higher the intensity of the light beam, the greater the number of photons per unit t...

_____ 1. X-ray photon passed through atom unchanged; no interaction _____ 2. Coherent scatter _____ 3. Photoelectric effect _____ 4. Compton scatter _____ 5. Bremsstrahlung radiation _____ 6. Radioactivity A. Electrons stop suddenly as they hit the anode. B. Ionization takes place when the photon ejects an outer shell electron. This results in the loss of energy for the photon and a negative charged electron. The low energy photon changes direction. C. An unstable atom releases energy...
