X-ray generating apparatus with integral housing

摘要

An X-ray generating apparatus is provided with a unitary vacuum enclosure (10) having a rotating anode target (16) and a cathode assembly (14) for generating X-rays transmitted through an X-ray window. The cathode assembly is placed within the vacuum enclosure through an opening (15) in the top wall thereof, and comprises a disk (28) which completely covers this opening. The unitary vacuum enclosure and the disk from a radiation shield. For increasing a thermal capacity of the unitary vacuum enclosure and installing the X-ray generating apparatus into a gantry it further comprises a mounting block (30) which may be coupled to or encompass the unitary vacuum enclosure. The X-ray window (32) is placed within the mounting block. A window adaptor may be utilized for the X-ray window installation.
