Imaging-guided delivery of X-ray radiation

摘要

An X-ray system comprises: (a) a source providing an X-ray diverging beam having treatment and imaging angular portions; (b) one or more lenses transforming the treatment portion of the X-ray beam into a converging beam directed to a target; (c) a first shutter located between the X-ray source and the target in the imaging portion of the X-ray radiation; the first shutter being selectively openable such that imaging portion of X-ray beam reaches the target; and (d) a detector configured to detect at least a portion of the imaging radiation after the imaging radiation has interacted with the target to provide imaging information of the target.

1. An X-ray system, comprising:
a. one or more lenses configured to receive X-ray radiation from a first X-ray source and to direct treatment radiation onto a target at one or more converging angles; b. a stop located in a direct path between the first X-ray source and the target, and positioned to block radiation from the first X-ray source that is not incident upon the one or more lenses from reaching the target; c. a second X-ray source positioned between the stop and the target, wherein the second X-ray source is configured to irradiate the target with imaging radiation; and d. a detector configured to detect at least a portion of the imaging radiation after the imaging radiation has interacted with the target.
