PET-CT Phantom,PET CT模體詳細(xì)介紹:
PET-CT Phantom™包括內(nèi)部結(jié)構(gòu)(三根桿和六個(gè)球體),當(dāng)用兩種模式成像時(shí),它們可以證明兩個(gè)圖像組的準(zhǔn)確對(duì)準(zhǔn)。
另外,放射性水的一個(gè)樣本被水,骨骼和CT造影材料(以及僅空氣)衰減,以確定基于CT的PET衰減校正工作的準(zhǔn)確度。
PET-CT Phantom,PET CT模體用于:
PET / CT和SPECT / CT系統(tǒng)的驗(yàn)收測(cè)試
PET / CT和SPECT / CT系統(tǒng)的常規(guī)質(zhì)量評(píng)估
評(píng)估新的圖像融合軟件
評(píng)估新的衰減校正算法
鋁管用于注冊(cè)
外部2“OD微型圓柱用于將衰減區(qū)域與非衰減區(qū)域進(jìn)行比較
6“環(huán)用于對(duì)比解決方案

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.
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.
The Phantom is used for:
Acceptance testing of PET/CT and SPECT/CT systems
Routine quality evaluation of PET/CT and SPECT/CT systems
Evaluation of new image fusion software
Evaluation of new attenuation correction algorithms
Aluminum tubes are for registration
The outer 2" OD micro cylinder is for comparing attenuation region to non attenuation region
The 6" ring is for contrast solution
