摘要:
The present invention uses the resilient behaviour of a flexible printed circuit board (10), both to mechanically clamp the components (20) in a permanent manner and to achieve good electrical contacts (24) between conducting parts (12) of the flexible circuit board (10) and the components (20). By cutting the flexible printed circuit board in such a manner that small tab-like, resilient members (12,16) are formed, the forces caused by elastically deformed resilient members (12,16) are usable both for mechanically fixing the components (20) and for causing an electrical contact (24). By choosing appropriate sizes of the resilient members (12,16), the relative strength of the spring force is increased, which even will be large enough to cause a plastic deformation of the material in the contact points (24) between the conducting resilient members (12) and the component contact members (22). In such a manner, soldering or gluing may be totally omitted.

摘要:
In the present invention we propose a new device for x-ray optics which is an analogy to the zone plates but working 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. The result will be the first ever device achieving true two dimensional focusing 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 will further be fairly straight forward to produce in large volumes.

The present invention relates to a device, method, array and use of the device for optical coupling. The device comprises first and second optical waveguides (13, 23) extending longitudinally with cores (14, 24) adapted to guide optical radiation (15), first resonator means, laterally surrounding the first waveguide, comprising first and second resonator members (18, 19), and second resonator means, laterally surrounding the second waveguide, comprising third and fourth resonator members (28, 29). The invention is characterized in that first and second deflector means (16, 26) are adapted to couple radiation propagating in the respectiv first and second waveguides with common radiation modes (30), which modes are defined by adjustable geometrical and material properties of the device, so as to obtain wavelength selective coupling of radiation guided by the first and second waveguides, provided the resonator means are tuned to the same resonance wavelength.

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.
