This article describes a model used in the nursing profession to promote an understanding of cultural diversity among employees and patients of health care facilities. The model addresses six factors important in cultural expression: communication, space, social organization, time, environmental control and biological variations. Managers in radiology departments can use the model as the basis for an educational in-service for employees and to build diverse, yet cohesive, work teams. The model also can be used as the basis for further scientific investigation into cultural diversity in diagnostic imaging and radiation therapy.
