Abstract

A device for generating x-rays has an enclosing vessel having a structure suitable to provide an enclosed space at a predetermined fluid pressure, wherein the enclosing vessel has a window portion and a shielding portion in which the shielding portion is more optically dense to x-rays than the window portion; a mechanoluminescent component disposed at least partially within the enclosing vessel; and a mechanical assembly connected to the mechanoluminescent component. The mechanical assembly provides mechanical energy to the mechanoluminescent component while in operation, and at least some of the mechanical energy when provided to the mechanoluminescent component by the mechanical assembly is converted to x-rays.

First claim

We claim:

1. A radiation source, comprising:
a contact element;
a surface element arranged proximate said contact element; and
a mechanical assembly operatively connected to at least one of said contact element and said surface element,
wherein said mechanically assembly is operable to at least separate said contact element from said surface element,
wherein at least some mechanical energy is supplied from said mechanical assembly while in operation to generate radiation while said contact element and said surface element are separated, and
wherein said radiation source has a maximum dimension less than about 1 cm.

2. A radiation source according to claim 1 , wherein said radiation source has a maximum dimension less than about 1 mm.

3. A radiation source according to claim 1 , wherein said mechanical assembly comprises a piezoelectric transducer.

4. A radiation source according to claim 1 , wherein said radiation generated by said radiation source comprises charged particles.

5. A radiation source according to claim 1 , wherein said radiation generated by said radiation source comprises electrons.

6. A radiation source according to claim 1 , wherein said radiation generated by said radiation source comprises electromagnetic radiation.

7. A radiation source according to claim 1 , wherein said radiation generated by said radiation source comprises x-rays.

8. A medical device comprising a radiation source according to claim 1 .

9. A medical device according to claim 8 , wherein said medical device has a portion containing said radiation source that is surgically insertable or is insertable within an orifice of a subject such that said radiation source can be brought into proximity to an internal region of said subject.
