我们开发了一种用于x射线后向散射成像的一维位置敏感探测器（1-D PSD），该探测器具有闪烁体-光纤位置敏感光电倍增管（PSPMT）结构。探测器的闪烁体被漫反射材料覆盖。探测器的聚四氟乙烯和光纤被镜面反射材料铝箔覆盖。探测器由1×25 LYSO阵列与25根塑料纤维耦合组成。这些纤维的另一端被扭曲成5×5阵列，并与PSPMT R8520耦合。探测器元件面积为4.2×20mm2and，位置分辨率为4.2mm。我们测试了探测器的定位直方图，建立了x射线后向散射成像系统，得到了探测器的x射线后向散射图像。
We have developed a one-dimensional position-sensitive detector (1-D PSD) for X-ray backscatter imaging which had a scintillator–fiber- position-sensitive photomultiplier (PSPMT) structure. Scintillators of the detector were covered by diffused reflection material. Teflon and the fiber of the detector was covered by mirror reflection material an aluminum foil. The detector was composed of a 1×25 LYSO array which was coupled with 25 plastic fibers. Another end of these fibers was twisted into a 5×5 array and coupled with a PSPMT R8520. The detector element's area was 4.2×20mm2and the position resolution was 4.2mm. We tested the positioning histogram of the detector set up an X-ray backscatter imaging system, and obtained an X-ray backscatter image from it.
