Experiences with processing control in the radiology department of a large municipal hospital

: Processing control is an important part of quality control in X-ray diagnostics. From 1 July 1984 to 31 December 1985 the processing of 10 of the 11 processors in the Radiology Department at the Augsburg Municipal Hospital was controlled regularly on a total of 304 days. The speed index was at 95.8%, the contrast index at 96.1% within the limits recommended by the Federal German DIN standard. Processing control has proved meaningful and effective in keeping processing on a constant level. It also indicates where to look for the reasons for poor image quality. It takes less than 5 minutes to carry out the processing control of one processor. Processing control is a task of the radiographer.
