Abstract
An x-ray tube includes an inner wall including a target surface and an outer wall disposed about the inner wall and defining a gap therebetween. A corrugated structure is disposed in the gap and is coupled to both the inner wall and the outer wall so as to define a plurality of channels therebetween. The corrugated structure is configured to allow a coolant to flow through the channels. An area inside of the inner wall is substantially maintained at a vacuum and a filament is disposed in the area inside of the inner wall. When a sufficient voltage is applied between the filament and the inner wall, the filament emits electrons directed to at least a portion of the target surface so that the target surface emits electrons.

An x-ray tube, comprising:
- (a) an inner wall including a target surface;
- (b) an outer wall disposed about the inner wall and defining a gap therebetween;
- (c) a corrugated structure disposed in the gap and coupled to at least one of the inner wall and the outer wall so as to define a plurality of channels therebetween, wherein the channels are configured to allow a coolant to flow through the channels, the inner wall, the outer wall and the corrugated structure forming a wall stiffening truss-like structure that is structurally rigid and that distributes force from outside air pressure on the outer wall;
- (d) a volume inside of the inner wall that is substantially maintained at a vacuum;
- and
- (e) a filament disposed in the area inside of the inner wall;
- wherein when a sufficient voltage is applied between the filament and the inner wall, the filament will emit electrons directed to at least a portion of the target surface so that the target surface emits x-rays.

- (b) an outer wall disposed about the inner wall and defining a gap therebetween;
- (c) a corrugated structure disposed in the gap and coupled to at least one of the inner wall and the outer wall so as to define a plurality of channels therebetween, the inner wall, the outer wall and the corrugated structure forming a wall stiffening truss-like structure that is structurally rigid and that distributes force from outside air pressure on the outer wall, wherein the channels are configured to allow a coolant to flow through the channels, the corrugated structure including a rectangular crenulated pattern that includes a repetition of:
- (i) an inner flat surface having a first end and an opposite second end, the inner flat surface being affixed to the inner wall;
- (ii) an outer flat surface laterally offset from the inner flat surface having a first end and an opposite second end, the outer flat surface being affixed to the outer wall;
- (iii) a first transverse surface that couples the second end of the inner flat surface to the first end of the outer flat surface;
- and
- (iv) a second transverse surface that couples the second end of the outer flat surface to the first end of a successive inner flat surface;
- (d) an area inside of the inner wall that is substantially maintained at a vacuum;
- and
- (e) a filament disposed in the area inside of the inner wall,
- wherein when a sufficient voltage is applied between the filament and the inner wall, the filament will emit electrons directed to at least a portion of the target surface so that the target surface emits x-rays.
