#11), Roberto takes a good radiograph using: 10 mAs, 200 cm SID and a 5:1 grid this produces an exposure of 3 Gya. (4 poin 11a) What would the new exposure 8:1 grid while keeping mAs constant? ts) be exposure if she substitutes a 100 cm SID and an 11b) What should the new mAs value be to maintain exposure if she subst cm SID and an 8:1 grid? itutes a 100 #12) At 25 mAs and 400 cm SID...
Increasing the kVp by 15% would have the same effect on IR exposure as what mAs increase?
Answer the following questions using the exposure maintenance formula If 80 kVp and 45 mAs is required to produce an adequate IR exposure at 72 inch SID, what new mAs would maintain the same IR exposure at 36 inch SID? What is the difference between the inverse square law and the exposure maintenance formula? In what situation would you use the inverse square law?
Radiology 9:26 Х Student Portal 1. A satisfactory radiograph is obtained using 10 mAs at an SID of 40". If the technologist were to repeat the exposure at a new SID of 72", what mAs value would be required to maintain radiographic exposure? 2. If a radiographic image is obtained at 40" using 32 mAs, and a repeat exposure would be performed at an ID of 80", what mAs would be required to produce an image demonstrating similar exposure? 3....
Answer the following questions using the exposure maintenance formula A lateral C-spine was imaged using a 40 inch SID and 25 mAs, what would the mAs be if the SID is changed to 60 inches? If 80 kVp and 45 mAs is required to produce an adequate IR exposure at 72 inch SID, what new mAs would maintain the same IR exposure at 36 inch SID?
3. To maintain IR exposure, how much? (1 point) if KCR is increased by 15%, what change(s) should be made and by 4. To maintain IR exposure, ifXpls decreased by 15%, what change(s) should be made and by how much? (1 point) An image was made using 75 kVp and 12 mAs to produce optimal IR exposure. What new set of exposure factors would produce the same IR exposure but with a 15%ncrease in kVp? (1 point) 5. 3. To...
