Elsevier Adaptive Quizzes A radiologic technologist is working on barium and iodine. Which term does the radiologic technologist use to refer to 134/56 Ba and 131/53 I ? a. Isobar b. Isomer c. Isotope d. Isotone - d. Isotone Isotones differ in their atomic numbers and mass numbers, but they have the same number of neutrons, that is, a constant for the quantity a (atomic number) - z (mass number) a-z. Types of ionizing radiation used in various techniques have different ranges of...

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...

ARRT Registry Practice Test 1 All of the following EXCEPT ___ will result in an increase in AEC response time. a. decreasing the kVp b. Increasing the focal spot size c. increasing the part thickness d. increasing the SID - ANSWER b. increasing the focal spot size Increasing the focal spot size does not change the AEC response time It affects the spatial resolution. Decreasing the kVp increases the exposure time because more photons are absorbed, resulting in...

Fluoroscopy ARRT Exam Study guide Questions With Accurate Answers. What mag modes are available? - answerif you have a 16" II, you can have 12,9,6, and 4.5 " Compton effect - answerhits the outer electron, incomplete transfer of energy, electron released and a low energy xray is deflected photoelectric absorption - answerx-ray totally absorbed by inner shell electron, x-ray overcomes binding energy and knock out the electron and an outer shell electron takes it place. When the outer ele...
