Many problems mutual to architects and radiologists are enumerated and a routine of action for the radiologist suggested. He should confer with clerical and technical personnel in his department, and with the professional staff of his own and other hospitals. He should learn the basic architectural data applicable to his department and should know space requirements for not only the technical work, but for other areas as well. Plans for periodic radiologist-architect conferences should be made, and additional consultations should be undertaken throughout all stages of both planning and construction, as needed.
