6.0 Aec Calibration (Wall Bucky) - CPI CMP 200 Series Service Manual

3D.6.0 AEC CALIBRATION (WALL BUCKY)
WALL
BUCKY
Please note the following points regarding wall Bucky calibration:
•
If the wall Bucky is dedicated to chest radiography, a focused grid with a 10:1 or 12:1 ratio should be used along with an SID of 72 in. (180
cm).
•
If the wall Bucky will be used for conventional as well as chest radiography, then two grids should ideally be used. See the note on the next
page.
A reasonable compromise if a single grid must be used is a 10:1 ratio, 60 in. (150 cm) grid.
Use and disclosure is subject to the restrictions on the title page of this CPI document.
