In a method and device for x-ray brachytherapy, a probe is inserted into and moved within a living subject, the probe having a distal end, an x-ray source carried by said probe at said distal end that irradiates an x-ray beam into an exposure area outside of the probe, a mark generator carried by said probe at said distal end that generates a mark that identifies at least a portion of said exposure area, and an optical observation system, having an optical detector carried at said distal of said probe, that generates an optical image of said at least one part of said exposure area that is identified by said marking, the marking being visible in said optical image. |
