An apparatus for delivering x-rays to a selected site within a body cavity comprising:
- an endoscope having a central lumen;
- an x-ray shield which is impenetrable to x-rays positioned in said central lumen, said x-ray shield being penetrable to x-rays at a distal end thereof;
- and
- at least two x-ray sources positioned in respective lumen of said x-ray shield, said x-ray sources being operably connected to a power source.
