Correlation between the results of medical x-ray processing labs and the USA Standard for processing medical x-ray film is lacking at present. In order to correct this, a developer formulation will have to be devised to obtain in the experimental laboratory the same results that are obtained by the automatic x-ray processing machines that are presently being used. In an attempt to accomplish this, a factorial experiment was designed in which two levels of the following five factors were varied: metol, hydroquinone, potassium bromide, development time, and film (both rapid process types). The results from this factorial (tray processing) would be compared with the results obtained from samples of the same kind of film and exposure processed by nine different field labs. From an analysis of the data, either a new developer would be evident that would give the same results with either process or new levels of the afore mentioned factors would be indicated in a follow-up factorial experiment. In the experiment performed, the latter case was the result. Increased levels of hydroquinone, metol and development time were indicated with potassium bromide held constant at the low level.
