Abstract:
1. A method of generating monochromatic radiation comprising: generating broad spectrum x-ray radiation from an x-ray tube comprising a first target that, in response to being irradiated by electrons, emits the broad spectrum x-ray radiation; directing at least some of the broad spectrum x-ray radiation to irradiate a second target comprising material that, in response to the irradiation, emits monochromatic x-ray radiation above an absorption edge of a contrast agent delivered to target tissue; directing at least some of the monochromatic x-ray radiation to irradiate target tissue; detecting at least some of the monochromatic x-ray radiation transmitted through the target tissue; and generating at least one image based, at least in part, on the detected monochromatic x-ray radiation.
