Filter for X-ray device, particularly computed tomography apparatus, to form intensity profile of X-rays outgoing from X-ray source, has hollow body partially arranged in fluid medium or oil for forming weak X-ray radiation

摘要

The filter (20) has a hollow body partially arranged in a fluid medium or oil for forming a weak X-ray radiation (8). The hollow body is filled with air, and is a cylinder, an ellipsoid or a section of an ellipsoid body. The fluid medium or oil is accommodated in a housing, and has a tissue-equivalent continuous radiation hardening property. An independent claim is also included for an X-ray device, particularly a computed tomography apparatus.
