CIRs 802 QA模體，Gillian QA模體主要用來驗證混合掃描系統(tǒng)中的圖像對齊和失真

Gillian QA Phantom SPECT / CT，PET / CT和CT / MRI CIRS 802 特征：
與SPECT / CT，PET / CT和CT / MRI兼容
檢查整個成像區(qū)域的對齊和變形
易于填充和排出
允許獨立評估設備功能
簡單的幾何形狀允許快速視覺解釋
諸如SPECT / CT，PET / CT和CT / MRI等混合掃描系統(tǒng)越來越多地用于改善腫瘤識別，治療實施和監(jiān)測治療效果。通過結(jié)合來自兩種不同成像模式的圖像，混合掃描系統(tǒng)利用各個成像模式的優(yōu)勢，同時最大限度地減少各自的弱點。正確對齊融合圖像是一個持續(xù)的問題。

CIRs 802 QA模體，Gillian QA模體為驗證圖像對齊和失真提供了一種簡單且經(jīng)濟高效的解決方案。CIRs 802 QA模體，Gillian QA模體由一個可以充滿各種流體的水密丙烯酸圓柱體組成。四個不同直徑的非平行桿貫穿缸的整個長度。用模體制作的圖像可以快速，清晰地顯示融合圖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 individual 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.
