A computed tomography method seeking higher resolutions without imposing a dose increase is described. A mask () forms a plurality of X-ray beam lets () which are passed through a subject (), and images are captured on X-ray detector (). The subject () is moved with respect to the X-ray detector and mask, including a rotation around a y axis, and a computed tomography image is reconstructed from the plurality of measured datapoints. The beam lets () are of small size. FIGS.-are blurred, FIGS.andcontain too small letters/numbers.

Computed tomography imaging

A method of X-ray imaging includes passing an X-ray beam through a pre-sample maskwith a plurality of apertures, through a sample, and then through a detector maskwith aligned apertures. The beams are detected. The detector maskand pre-sample maskare moved with respect to one another to identify the position of maximum intensity and then moved to two further positions on equal and opposite spacings on either side of the maximum. Images are acquired and a transmission image, refraction image and scattering image calculated.
