    • A method for fabricating an array adapted to receive a plurality of scintillators for use in association with an imaging device. The method allows the creation of a detector array such that location of the impingement of radiation upon an individual scintillator detector is accurately determinable. The array incorporates an air gap between all the scintillator elements. Certain scintillators may have varying height reflective light partitions to control the amount of light sharing which occurs between elements. Light transmission is additionally optimized by varying the optical transmission properties of the reflective light partition, such as by varying the thickness and optical density of the light partitions. In certain locations, no light partitions exist, thereby defining an air gap between those elements. The air gap allows a large increase in the packing fraction and therefore the overall sensitivity of the array.
    • 一种用于制造适于接收与成像装置相关联使用的多个闪烁体的阵列的方法。 该方法允许创建检测器阵列,使得能够精确地确定单个闪烁体检测器上的辐射冲击位置。 该阵列包括所有闪烁体元件之间的气隙。 某些闪烁体可以具有变化的高度反射光分区,以控制在元件之间发生的光共享的量。 通过改变反射光分区的光传输特性,例如通过改变光分区的厚度和光密度来另外优化透光。 在某些位置,不存在光分区,从而在这些元件之间限定气隙。 空气间隙允许包装分数大幅度增加,因此阵列的整体灵敏度增加。

    • A method for improving timing response in light-sharing scintillation detectors is disclosed. The method includes detecting an event, by a plurality of photo sensors, from a scintillation crystal. The method then includes sampling and digitizing the photo sensor outputs by an analog-to-digital converter. Then the method includes correcting associated timing data, by a processor, for each of the photo sensor outputs based on a lookup table. The method then includes selectively time shifting the photo sensor outputs based on the lookup table to generate corrected photo sensor outputs. The method then includes summing the corrected photo sensor outputs by the processor. The method then includes generating an event time, by the processor, for the detected event based on the sum of the corrected photo sensor outputs.
