Title: X-ray device
Inventor: KAWAI MASUMI
IPC: H05G1/02
Filed: 1992-09-30
Abstract: PURPOSE:To lessen the X-ray dosage to the skin of a human body to be irradiated by controlling the effective filter thickness according to the information about the tube voltage, by increasing the filter thickness when the tube voltage is low, and thereby reducing soft X-ray. CONSTITUTION:The scope of irradiation is restricted by furnishing a lead cone 2 at the X-ray irradiation aperture of an X-ray tube 1, and in the neighborhood of the cone 2, a collimator 3 for X-ray is installed which has a movable filter device 4 confronting the cone 2, and is operated in conformity to the tube voltage signal given by an X-ray control device, not illustrated, i.e., a kV signal. The device 4 is formed from two aluminum plates 41, 42, for example in the form of varying thickness in wedge shape, and these are moved in opposite directions simultaneously as indicated by arrows and intruded into and retreated from the scope of X-ray irradiation so that the effective thickness varies. Because the device 4 is only required to have a varying effective thickness for the X-ray penetrating the device, its may also be accepted that aluminum plate of a certain thickness is rotated round the axis to adjust the X-ray amount passing. In this manner, soft X-ray are lessened which do not contribute to photo-sensing of an image intensifier.
