Description

FIG. 1 is a top-front-left perspective view of a cathode shield according to the claimed design.
FIG. 2 is a front view of the cathode shield.
FIG. 3 is a rear view of the cathode shield.
FIG. 4 is a left side view of the cathode shield.
FIG. 5 is a right side view of the cathode shield.
FIG. 6 is a bottom view of the cathode shield.
FIG. 7 is a top view of the cathode shield.
FIG. 8 is a top-front-left perspective view of the cathode shield in a use environment showing a portion of an X-ray tube and cathode.
FIG. 9 is a sectional view of the cathode shield along line 9-9 in FIG. 7 ; and,
FIG. 10 is a sectional view of the cathode shield along line 10-10 in FIG. 7 .
The dash-dash broken lines in FIG. 8 of the drawings showing the portion of the X-ray tube and cathode illustrate environmental matter that forms no part of the claimed design.
The dash-dot-dot sectional broken lines in FIG. 7 of the drawings form no part of the claimed design.
