摘要： A new device for x-ray optics is proposed which is an analogous to zone plates but works for higher x-ray energies. This is achieved by using both refraction and diffraction of the x-rays and building the new device(s) in a three dimensional structure, contrary to the zone plates which are basically a two dimensional device. The three dimensional structure is built from a multitude of prisms, utilizing both refraction and diffraction of incoming x-rays to shape the overall x-ray flux. True two dimensional focusing is achieved in the x-ray energy range usually employed in medical imaging and may be used in a wide area of applications in this field and in other fields of x-ray imaging. The device can be readily produced in large volumes.

摘要： A guide wire assembly includes a proximal end portion, a distal portion comprising a coil, a hollow stranded wire extending towards the distal portion, and a core wire. The guide wire assembly is characterized in that a proximal tube is provided, which extends from the proximal end portion to a proximal end of the hollow stranded wire such that the hollow stranded wire is directly joined to the proximal tube. The core wire extends into the distal portion and does not extend into the proximal tube. An entire length of the hollow stranded wire is in a range of 7.5 to 22.5% of an entire length of the guide wire assembly.

摘要： A Silicon detector for x-ray imaging is based on multiple semiconductor detector modules (A) arranged together to form an overall detector area, where each semiconductor detector module includes an x-ray sensor of crystalline Silicon oriented edge-on to incoming x-rays and connected to integrated circuitry for registration of x-rays interacting in the x-ray sensor through the photoelectric effect and through Compton scattering and for an incident x-ray energy between 40 keV and 250 keV to provide the spatial and energy information from these interactions to enable an image of an object. Further, anti-scatter modules (B) are interfolded between at least a subset of the semiconductor detector modules to at least partly absorb Compton scattered x-rays.
