POSITRON TOMOGRAPH USING OPTICALLY COUPLED DETECTORS

这项赠款的目的是建设和评估一个 正电子发射断层扫描仪（PET），具有20- 30的大轴向视野 25厘米 该设备将非常适合全身调查 在转移性肿瘤的检测和分期中是必要的;它将具有 两倍的视野和四倍的当前状态的灵敏度- 最先进的PET扫描仪 这种性能改进可能会 有必要实施和评估一个全面的三维 重建算法 初步结果显示， 算法不仅会提高图像质量， 考虑到现有技术， 可接受的重建时间。

The objective of this grant is the construction and evaluation of a Positron Emission Tomograph (PET) with a large axial field of view of 20- 25 cm. This device will be ideally suited for whole body surveys necessary in the detection and staging of metastatic tumors; it will have twice the field of view and four times the sensitivity of current state- of-the-art PET scanners. This performance improvement possible it will be necessary to implement and evaluate a fully three-dimensional reconstruction algorithm. Preliminary results indicate that this algorithm will not only improve the image quality but it will also be possible to implement it given existing technology with clinically acceptable reconstruction times.
