Paper Abstract

In the fall of 1972, the Central Diagnostic Laboratories of Barnes Hospital, St. Louis, Missouri, evaluated several commercial instruments for automation of disc sensitivity test reading and colony counting in the clinical microbiology laboratory. None of the available devices were capable of reading sensitivity test results without assistance from an operator, and the costs of the more nearly automatic ones were so high as to render their cost justification questionable. It was decided that the construction of a fully automatic high speed petri dish reading instru-ment at a cost appreciably lower than existing devices should be possible if a high speed minicomputer were used as a control element and if the price of the optoelectronic components could be kept down by designing to limited performance criteria. Additionally, for reliability and ease of construction, readily available components were to be used throughout.
