Embodiment Construction

[0040] figure 1 An exemplary embodiment of a method 10 for producing a scintillator fiber in a first embodiment according to the invention is shown. The method 10 comprises the steps of providing 12 a suspension of binding agent and scintillator material dissolved in a solvent, and hydraulically injecting 14 the suspension into a precipitation bath in which the binding agent is insoluble. During this time, the scintillator fiber is formed as a green body. The providing step 12 may comprise the generation of a solution or suspension. A solution is produced from a binder and a solvent. This solution is added to the scintillator material. The scintillator material exists as powder luminescent material or powder scintillator material. The application of agitation, ultrasonic or centrifugal mixers is used to mix the scintillator material into the solution uniformly and without bubbles, thus forming a suspension. The suspension provided is then pressed into the precipitation ba...

The invention relates to a method (10) for producing a scintillator optical fiber (1), the method comprising the steps of providing (12) a suspension of binder and scintillator material dissolved in a solvent, and injecting the suspension into ( 14) To a precipitation bath in which the binding agent is insoluble.

Description

technical field [0001] The invention relates to a method for producing a scintillator fiber, a method for producing a scintillator unit, a scintillator unit, an X-ray detector and a medical device. Background technique [0002] Integrating an indirect conversion X-ray detector can be used in X-ray imaging, for example in computed tomography, angiography or radiography. The information contained in the local modulation of incident X-rays is detected by an X-ray detector, which converts the information into digital signals. In an indirect conversion X-ray detector, X-rays or photons are converted into light by means of suitable converter materials and into electrical pulses by means of photodiodes. The converter material used is often a scintillator such as GOS (Gd 2 o 2 S), CsJ, YGO or LuTAG. The scintillator unit includes converter material. Scintillators are used in particular in medical X-ray imaging in the energy range up to 1 MeV. Usually, so-called indirect conver...
