强子疗法的选择性能量沉积引起了人们对质量保证技术的兴趣，如“束内”PET。由于目前缺乏商业解决方案，需要开发专用探测器。在本文中，我们比较了两种不同的“束内”PET系统在GSI达姆施塔特PMMA低能碳离子辐照期间和之后的性能。结果突出了新型束内PET原型与长期临床操作的离子治疗监测断层成像的优点和缺点。
The selective energy deposition of hadrontherapy has led to a growing interest in quality assurance techniques such as 'in-beam' PET. Due to the current lack of commercial solutions, dedicated detectors need to be developed. In this paper, we compare the performances of two different 'in-beam' PET systems which were simultaneously operated during and after low energy carbon ion irradiation of PMMA phantoms at GSI Darmstadt. The results highlight advantages and drawbacks of a novel in-beam PET prototype against a long-term clinically operated tomograph for ion therapy monitoring.
