Simulations of angiography x-ray source based on electron channeling in crystals
The article concerns with the new method of acquiring the narrow-band X-ray energetic spectrum based on the idea of electron channeling in crystals. Polycapillary X-ray filter exploited in this method helps to eliminate the high-energy part of the spectrum and obtain dramatical reduction of the absorbed doses. This method may find particularly important applications in angiography that has nowadays become the state of the art medical imaging technique for visualization of the blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers. X-ray sources in angiography applications are based only on the X-ray tubes that are really well investigated. The main drawback of the tubes is wide spectrum width of the generated radiation. Monochromatic radiation source application can result in better imaging, and, moreover, lower irradiation dose can be applied to a patient.
