Abstract
An imaging tube (51) is provided including a cathode (58) and an anode (60). The cathode (58) includes an emission surface (99), which emits a plurality of electrons along an emission axis (56). The anode (60) includes a body (76) having a track (58) on a peripheral section (78) of the body (76). The plurality of electrons are directed to impinge on the track (58) at an impingement angle α approximately equal to or between 15° and 25° relative to the emission axis (56) and are converted into x-rays. A method of generating x-rays within the imaging tube is also provided.
Claims20
An imaging tube comprising:
- a cathode comprising an emission surface emitting a plurality of electrons along an emission axis;
- and
- an anode comprising;
- a body comprising a track on a peripheral section of said body;
- wherein said plurality of electrons impinge on said track at an impingement angle approximately equal to or between 15° and 25° relative to said emission axis and convert into x-rays.
A method of generating x-rays within an imaging tube comprising:
- emitting a plurality of electrons from a cathode along an emission axis;
- impinging said plurality of electrons on an anode at an impingement angle of approximately equal to or between 15° and 25° relative to said emission axis to generate x-rays;
- and
- directing said x-rays through an x-ray window.
An imaging tube comprising:
- a cathode comprising an emission surface emitting a plurality of electrons along an emission axis;
- and
- an anode comprising;
- a body comprising;
- a track define by a pair of collared ends on a peripheral section of said body;
- and
- an inner thermal transient hub section thermally coupled to and absorbing thermal energy from said body;
- wherein said plurality of electrons impinge on said track at an impingement angle approximately equal to or between 15° and 25° relative to said emission axis and convert into x-rays.
