Abstract

The invention relates to a laser engraving system and an anisotropic scintillator and a manufacture method thereof. The anisotropic scintillator is used to capture photons in an imaging system. The anisotropic scintillator comprises a scintillator component and a 3D structure formed in the scintillator component. The 3D structure comprises multiple anisotropic parts. The anisotropic parts include at least one selected from optical characteristics and are used to store space information. Each anisotropic part comprises gaps or air bubbles, the diameter of each gap or air bubble is lower than 1 micron. The 3D structure controls the photons to spread in channel areas formed in the anisotropic scintillator, thereby reducing the amount of photons that are spread among the channel areas.

Description

technical field [0001] The present invention relates to a method of generating optical anisotropy in scintillator materials, in particular, to a method of generating optical anisotropy in scintillator elements for application in medical imaging. Background technique [0002] Medical imaging uses scintillators to convert gamma rays or X-rays into optical photons. A scintillator is typically coupled to a photodetector, which converts the aforementioned optical photons into an electric current. In this way, gamma rays and X-rays can be detected and used for example in computed tomography (CT), positron emission tomography (PET), single photon emission computed tomography Scanning (single photon emission computedtomography, referred to as SPECT), and X-ray imaging and other applications. In these applications, the location of the gamma-ray or X-ray interaction is determined by the response of the photodetector to the optical photon. [0003] The characteristics and properties...
