In conclusion, it is obvious that the delivery system for medical care is changing much faster than anticipated. Technology is the agent in this process and economics is both the driving and the limiting force: driving because it is the impetus to change the sites of medical practice, limiting because of the constrained number of dollars to allocate to technology acquisition and operation. As we move into the future, it cannot be emphasized too strongly that hospitals and industry should be complementary in this process. To do so successfully requires an understanding of the mission each seeks to pursue and of what each can do for the other.
