Abstract
Miniature X-ray source comprising a support structure provided with a through-going hole, an anode is arranged at one end and a cathode (8,24) at the other end of the hole, thereby defining a cavity, the anode and cathode are adapted to be energised in order to generate X-ray radiation. The support structure has a cross-sectional shape that is determined such that a desired radiation distribution of the radiation generated by the X-ray source is achieved. Also a method of manufacturing miniature X-ray sources is disclosed.

Miniature X-ray source comprising a support structure (4,26) provided with a through-going hole (6,20), an anode (10,22) is arranged at one end and a cathode (8,24) at the other end of the hole, thereby defining a cavity, the anode and cathode are adapted to be energised in order to generate X-ray radiation, characterized in that the support structure has a cross-sectional shape that is determined such that a desired radiation distribution of the radiation generated by the X-ray source is achieved.
Method of manufacturing miniature X-ray sources comprising the following steps:
- i) making through-going holes, one for each X-ray source to be manufactured, in a disc-shaped support structure wafer having an even thickness,
- ii) arranging for each hole an anode and a cathode at opposite sides of the wafer and thereby defining an X-ray source cavity between the anode and the cathode,
- iii) dividing the wafer into separate elements where each element includes an X-ray source and where the support structure of each X-ray source has a predefined outer shape that is determined such that a desired radiation distribution of the radiation generated by the X-ray source is achieved.
