A patient presents whose radiographs must be taken utilizing the bisecting technique. The radiographer decides to replace the 16-in. (41-cm) PID with an 8-in. (20.5-cm) PID to better accommodate the bisecting technique. Currently the impulse setting, with the 16-in. (41-cm) PID, is 12. To maintain image density, what will the new impulse setting be with the 8-in. (20.5-cm) PID?

a. 3

b. 6

c. 24

d. 48
