在这项工作中，我们证明了高空间分辨率切伦科夫发光成像（CLI）的透明介质中的对象的可能性。我们还证明了使用光学换能器的薄的不透明物体的CLI的可能性。结果表明，亚毫米分辨率CLI是可以实现的β发射放射性核素，包括发射非常高能量的正电子。通过闪烁探测器对β-发射体进行成像，与相同源的CLI相比，分辨率较低。使用标记有和含有β-发射体的植物演示了用于CLI的光学换能器的应用。
In this work, we demonstrated the possibility of high spatial resolution Cherenkov luminescence imaging (CLI) for objects in transparent media. We also demonstrated the possibility of the CLI of thin opaque objects using optical transducers. Results demonstrate that submillimeter resolution CLI is achievable for beta-emitting radionuclides, includingthat emits positrons of very high energy. The imaging of beta-emitters through scintillation detectors exhibits lower resolution when compared to CLI of the same sources. The application of optical transducers for the CLI was demonstrated using plants labeled withand phantoms containing beta-emitters.
