Patent
·
OSTI ID:6809238
A slit collimator is disclosed for use in a panoramic X-ray apparatus for the collimation of X-rays into a narrow fan-like beam. The collimation is achieved by means of a collimator slit formed in a trunion which is rotatable about its longitudinal axis and by rotating the trunion the effective radiation-penetrable size of the slit is varied.
