COLLIMATOR FOR X-RAY, GAMMA, OR PARTICLE RADIATION

摘要

The invention relates to a collimator for X-ray, gamma, or particle radiation, which has a plurality of collimator elements made of a material containing tungsten in order to reduce the scatter radiation, wherein at least one collimator element is made of a tungsten alloy having a tungsten content of 72 to 98 wt %, wherein said tungsten alloy contains 1 to 14 wt % of at least one metal of the group Mo, Ta, Nb and 1 to 14 wt % of at least one metal of the group Fe, Ni, Co, Cu. The collimator has very homogeneous absorption behavior even if the walls of the collimator elements are very thin.
