【PET CT模體??】

PET CT Phantom?

型號/Model：PET/CT/P

PET CT模體?主要特點:

-該PET-CT模體?內部含三個冷棒及六個實心球，成像時可清晰體現兩者的位置精確度和幾何形變情況。

The PET-CT Phantom? includes internal structures (three rods and six spheres) which when imaged with both modalities can demonstrate how accurately the two image sets are aligned.

-此外，經水、骨骼及CT對比顯影物質(或僅通過空氣)等介質衰減后的放射性水樣本可用于判定基于CT的PET衰減校正準確性。

In addition, a single sample of radioactive water is attenuated by water, bone, and CT contrast material (as well as air only) to determine how accurately the CT-based PET attenuation correction works.

PET CT模體?主要應用領域:

-PET/CT(正電子發射斷層顯像/X線計算機體層成像)及SPECT/CT(單光子發射斷層顯像/X線計算機斷層顯像)系統驗收測試

Acceptance testing?of PET/CT and SPECT/CT system

-PET/CT及SPECT/CT系統例行質量評估

Routine quality evaluation of PET/CT and SPECT/CT Systems

-新圖像融合軟件的評估

Evaluation of new image fusion software

-新衰減校正算法的評估

Evaluation of new attenuation correction algorithms

-含配準用鋁管

Aluminum tubes are for registration
-外部直徑2英寸(5.08cm)微型圓筒用于比較衰減區域和不衰減區域

The outer 2” OD micro cylinder is for comparing attenuation region to non attenuation region

-6英寸(15.24cm)圓環用于防止對比顯影液

The 6” ring is for contrast solution

-科研應用
