X-RAY TUBE CONTAINING A UNIVERSAL LIMITER FOR SECONDARY RADIATION |
摘要 |
A universal limiter for any type of x-ray tube used in radiology or radiation therapy comprises an envelope of conical shape whose axis coincides with the axis of symmetry of the useful beam of radiation. The limiter is formed of material which is opaque to secondary radiation. The inlet aperture of the limiter is located in the immediate vicinity of the emitting focal spot and the outlet aperture of the limiter is connected mechanically to the exit window of the x-ray tube. |
