93	Method for coded-source phase contrast X-ray imaging	US14400703	2013-03-14	US10045752B2	2018-08-14	Rajiv Gupta; Luis Fernando Velasquez-Garcia; Richard Lanza; Berthold K P Horn; Akintunde Ibitayo Akinwande
Described here is a method for performing phase contrast imaging using an array of independently controllable x-ray sources. The array of x-ray sources can be controlled to produce a distinct spatial pattern of x-ray radiation and thus can be used to encode phase contrast signals without the need for a coded aperture. The lack of coded aperture increases the flexibility of the imaging method. For instance, because a fixed, coded aperture is not required, the angular resolution of the imaging technique can be increased as compared to coded-aperture imaging. Moreover, the lack of a radioopaque coded aperture increases the photon flux that reaches the subject, thereby increasing the attainable signal-to-noise ratio.

95	IMAGING WITH ENHANCED X-RAY RADIATION	US15743304	2016-07-12	US20180214093A1	2018-08-02	Gerhard MARTENS; Ewald ROESSL
The invention relates to an X-ray imaging apparatus (2), comprising: a source (4) for generating X-ray radiation, an object receiving space (6) for arranging an object of interest for X-ray imaging, an X-ray collimator arrangement (8) arranged between the source (4) and the collimator arrangement (8), and an X-ray mirror arrangement (10). The mirror arrangement (10) comprises for example two tapered mirrors (22) facing each other and adapted for guiding X-ray radiation of the source (4) to the collimator arrangement (8). Consequently, the X-ray intensity at the object receiving space (6) is increased. In order to limit the X-ray radiation to an area, where the X-ray radiation can be utilized form imaging, an angle of spread Θm between the mirrors (22) and a length LM of each mirror (22) is adapted, such that a number of total reflections of X-ray radiation, provided by the source (4), at the mirrors (22) is limited. The limitation provides the effect that an angle of reflection Θr of the totally reflected X-ray radiation is limited. Consequently, an X-ray intensity at the object receiving space (6) is increased while constrains are provided, which prevent a large increase of a width of the X-ray radiation provided at the object receiving space (6), which effectively improves an imaging quality of an object of interest being arrangeable at the object receiving space (6).
