Abstract
The invention relates to a miniature X-ray source device connected to a distal end of a guiding wire for insertion towards a desired location within an animal body for effecting radiation therapy, said X-ray source device at least comprising a vacuum tube accommodated in said housing containing a cathode and an anode spaced apart at some distance from each other; electron freeing means for freeing electrons from the cathode; electric field means for applying during use a high-voltage electric field between said cathode and said anode for accelerating said free electrons; said vacuum tube being at least partly transparent to X-ray radiation emitted by said anode, as well as cooling means for cooling at least said anode.It is an object to provide a miniature X-ray source device having further limited constructional dimensions and an improved control of the working temperature of at least the anode and hence the working conditions of the miniature X-ray source device.According to the invention the miniature X-ray source device is hereto characterised in that said cooling means are cryogenic cooling means. More in particular in a specific embodiment of said miniature X-ray source devic…
