DETERMINISTIC LIGHT CONTROL IN SCINTILLATION CAMERAS

描述：光控制新技术的可行性 在闪烁相机中将进行测试。该方法具有一定的适用性 到任何类型的固体闪烁体，并且可以缩小固有的 光的显著扩散，从而允许改进的空间 决议。此外，有可能确定地 调整光扩散函数以具有所需的特性。 这项技术适用于任何愤怒的相机--尤其是那些 使用厚厚的闪烁体。特别是，空间分辨率 对于足够厚的晶体，可以保留低能量成像 在511keV时具有良好的探测效率。 第一阶段的工作将评估CSI和NAI的可行性 闪烁体，并将为一个 厚实的水晶相机。

DESCRIPTION: The feasibility of a new technique for light control in scintillation cameras will be tested. The method is applicable to any type of solid scintillator and can narrow the intrinsic spreading of light significantly thereby allowing improved spatial resolution. Furthermore, it will be possible to deterministically tailor the light spread function to have desirable properties. The technique is suitable for any Anger camera--especially those employing thick scintillators. In particular, spatial resolution for low- energy imaging can be retained for a crystal thick enough to have good detection efficiency at 511 keV. The Phase I effort will evaluate feasibility for both CsI and NaI scintillators and will develop light-control parameters for a thick-crystal camera.
