Rotating radiation shielded entrance assembly
First Claim
Patent Images
1. A rotating entrance assembly for a radiation treatment comprising:
- a rotating base that rotates about a vertical axis;
first and second shielding components arranged on the rotating base, the first and second shielding components have spaced apart opposing planar surfaces that define a linear through passageway extending between the first and second shielding components and through the vertical axis, each of the opposing planar surfaces extending along the entire length of the linear through passageway; and
a motor in driving connection with the rotating base.
