Abstract
A prototype automatic collimator for diagnostic X-ray machines was developed by the X-ray Exposure Control Laboratory. A second prototype was developed at XECL and installed in the Clinical Center of the National Institutes of Health for clinical evaluation. Subsequent use of this device has demonstrated technician acceptance. Modifications, based upon the X-ray technicians' evaluations, were made in the automatic collimator installed at the NIH. (Author)
