Abstract
An insulating housing shell for a miniature x-ray emitter is provided. The housing shell is cut from a quartz monocrystal which is a suitable material for the insulating housing shell due to its resistivity and dielectric strength properties. The x-ray emitter can be inserted into a subject's body to deliver x-ray radiation. The emitter includes a cable, having a proximal and a distal portion. The insulating housing shell is coupled to the distal portion of the cable, and an anode and a cathode are disposed within the insulating housing shell. The cathode has a granular surface and is operative with the anode and the connector to produce the x-ray radiation. The cathode is composed of a material that also allows it to act as a getter.
