CIRs 802 QA模体，Gillian QA模体主要用来验证混合扫描系统中的图像对齐和失真
Gillian QA Phantom SPECT / CT，PET / CT和CT / MRI CIRS 802 特征：
与SPECT / CT，PET / CT和CT / MRI兼容
检查整个成像区域的对齐和变形
易于填充和排出
允许独立评估设备功能
简单的几何形状允许快速视觉解释
诸如SPECT / CT，PET / CT和CT / MRI等混合扫描系统越来越多地用于改善肿瘤识别，治疗实施和监测治疗效果。通过结合来自两种不同成像模式的图像，混合扫描系统利用各个成像模式的优势，同时最大限度地减少各自的弱点。正确对齐融合图像是一个持续的问题。
CIRs 802 QA模体，Gillian QA模体为验证图像对齐和失真提供了一种简单且经济高效的解决方案。CIRs 802 QA模体，Gillian QA模体由一个可以充满各种流体的水密丙烯酸圆柱体组成。四个不同直径的非平行杆贯穿缸的整个长度。用模体制作的图像可以快速，清晰地显示融合图像中是否存在任何不匹配。
Gillian QA Phantom SPECT/CT, PET/CT and CT/MRI CIRS 802
Verifies Image Alignment and Distortion In Hybrid Scanning Systems
Gillian QA Phantom SPECT/CT, PET/CT and CT/MRI CIRS 802 Features:
Compatible with SPECT/CT, PET/CT and CT/MRI
Check alignment and distortion across the entire imaging field
Easy to fill and drain
Allows for independent assessment of equipment function
Simple geometry allows for quick visual interpretation
Hybrid scanning systems such as SPECT/CT, PET/CT and CT/MRI are increasingly being used to improve tumor identification, treatment delivery and monitor treatment effectiveness. By combining images from two different imaging modalities, hybrid scanning systems take advantage of the strengths of inpidual imaging modalities while minimizing their respective weaknesses. Proper alignment of the fused images is an ongoing concern.
The Model 802 Gillian QA phantom provides a simple and cost effective solution to verify image alignment and distortion. The phantom consists of a water tight acrylic cylinder that can be filled with a variety of fluids. Four non-parallel rods of varying diameter run the entire length of the cylinder. Images produced with the phantom can quickly and clearly show if there is any mismatch in the fused images.
