Abstract
This is the fourth of a series of articles on the planning and building of anew radiology department or the extension of an old one. While the series focuses on a radiology department, it will be of interest to anyone who is planning any part of a hospital, particularly in the detailed information about the planning process and the part to be played by hospital staff during the subsequent building and commissioning. (The first article in the series appeared in the January issue, p 40.)
