C-arm holding apparatus and X-ray diagnostic apparatus

摘要

An X-ray diagnostic apparatus includes a floor rotating arm (54) which is installed at one end on a floor surface so as to be rotatable around a first rotation axis (Z1), a C-arm (51) which is mounted on the other end of the floor rotating arm so as to be rotatable around a second rotation axis (Z2), an X-ray tube (1) which is mounted on one end of the C-arm, an X-ray detector (2) which is mounted on the other end of the C-arm, and a bed (17) which has a table top provided to be movable along a longitudinal axis. The bed is placed such that the longitudinal axis is spaced apart from the first rotation axis (Z1) by a predetermined distance.
