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?
A spring with a mass on the end of it hangs in equilibrium a distance of 0.4200m above the floor. The mas is pulled down a distance of 0.0600m below the original position, released, and allowed to oscillate. How high above the floor is the mass at the highest point in its oscillation? Show work.
#21) A radiographic technique pr c. oduces an exposure of 4 Gya at a source-to-image receptor distance (SID) of 200 cm and 100 kV, 20 mAs. The technique is changed to 400 cm and 115 kV. (4 pts) 21a) Find the new exposure in R if mAs is constant. If you want to maintain exposure what should the new mAs value be?

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....
#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...
