[ROKO--computer-assisted roentgen quality control].

To guarantee the quality of 30 x-ray machines and 8 photographic processors 24,000 data are collected yearly. A computer system is introduced (ROKO-Röntgenkonstanzprüfung) which helps to collect the monthly data easily and to measure on-line dose and voltage. If given tolerance values are exceeded acoustic and graphic warnings appear, a trend analysis is made to assure the correctness of the collected data, a generator to design the layout of check form facilitates the controlling and an on-line documentation for each x-ray machine is available. All these features help save time and money.
