An application of molecular imaging using TOF-PET/CTfor radiation treatment planning

本研究的目的是建立一种利用飞行时间(TOF)- PET / CT系统有效利用分子成像进行放射治疗计划的方法。我们发现TOF校正有助于提高PET/CT的定量和诊断性能。确定了最佳检查条件、呼吸运动补偿方法和肿瘤轮廓提取阈值。我们开发了一个程序，使用PET/CT图像放射治疗计划，并发现它是一个有用的辅助工具，计划。

The purpose of this study is to establish a method for effectively utilizing molecular imaging using time-of-flight (TOF)- PET / CT system for radiation treatment planning. We found that the TOF correction is useful for improving the quantitative and diagnostic performance of PET/CT. We determined the optimal examination conditions, the methods to compensate respiratory motion and the thresholds to extract tumor contour. We developed a program to use PET/CT images to radiation treatment planning and found that it was useful as a support tool for planning.
