What are Technique Charts?
A. Technique charts are printed charts attached to the wall or printed on the X-ray machine showing what the exposure factors should be for each particular exam. It is essential to have technique charts posted. All X-ray units perform differently, so a chart showing what one particular machine requires to make a good exposure needs to be in plain view at each machine. Not all staff use the same machine all the time and frequently, part time staff will be called in to perform work. Cleaning staff can sometimes bump the settings. All these factors can and do lead to a confusing array of potentially inappropriate selection of exposure factors. The inspection program tests the accuracy of these charts.
