The present invention provides improvements of resolution and contrast in the field of x-ray imaging by using a line emitting, quasi- monochromatic x-ray source for x-ray fluorescence computed tomography. A particular type of x-ray source suitable for this is a line emitting liquid-jet- anode x-ray source. X-ray fluorescence is obtained using nanoparticles, preferably coated nanoparticles with a metallic core. The x-ray radiation from the x-ray source is shaped and filtered using energy dispersive optics before being delivered to the nanoparticles. 本发明通过使用用于x-射线荧光计算机断层扫描术的线发射的、准单色的x-射线源，提供了在X-射线成像领域中分辨率和对比度的提高。适合用于此目的的特定类型的x-射线源是线发射的液体喷射阳极x-射线源。使用纳米粒子，优选具有金属核心的涂覆纳米粒子获得X-射线荧光。来自x-射线源的x-射线辐射在被递送到纳米粒子之前使用能量色散光学器件整形和滤光。
