Abstract:
1. An x-ray tube comprising: an envelope; a cathode mounted within the envelope; and an anode target rotatably mounted about an axis of rotation within the envelope and spaced relative to the cathode, wherein the target includes an axially-extending peripheral portion defining first and second approximately v-shaped groove portions axially spaced adjacent to each other in an axial direction along the axis of rotation, the first and second groove portions are each defined by a base and first and second opposing side walls, respectively, that diverge outwardly relative to each other in an approximately v-shaped configuration and substantially radially relative to the axis of rotation, the first side walls intersect a common plane extending substantially parallel to the axis of rotation, the second side walls intersect said common plane, and at least one of the approximately v-shaped groove portions of the target cooperates with the cathode to define thereon at least one x-ray focal track.
