Multi-Energy-QA模体，QRM-10150多能模体

使用双能、多能或光子计数设置测试不同类型的 CT 模式

测试多能光谱 CT 协议和后处理技术

分解碘和钙酸水平

该模型旨在通过双能、多能或光子计数设置测试不同类型的 CT 模式。模体由一个可拆卸/独立的头部模体（Ø 160 mm圆柱体）组成，带有10个孔（Ø 25 mm）以容纳不同的刀片和一个椭圆形（QRM-10150）或可选的圆形（QRM-10151）主体，配备9个孔。阀体和头部由水当量材料（CTwater）制成。

Multi-Energy-QA模体，QRM-10150多能模体配备了一套 26 个插入物，包括富含多种造影剂（水+碘、脂肪+碘）以及钙（水 + 羟基磷灰石钙）的棒，每种材料具有不同的浓度。此外，还包括水和软组织等效插入物（脂肪，肝脏，大脑 - ICRU报告44和46）。为所有材料提供质量密度、浓度和电子密度。

不同的ICRU组织和钆插入物可作为选项提供。

 

Test different types of Multi-Energy, 

Dual-Energy and Photon-Counting CT 

Protocols. 

Perform System QA on DECT and PCCT 

systems.

Investigate water and fat enriched 

with iodine and calcium.  

The phantom is designed to test different types of CT modalities with dual-energy, multi-energy or photon-counting setups.

Image acquisition and image processing at multiple energy levels is improving visualization for computed tomography. The QRM Multi-Energy QA phantom is ideally suited to test multi-energy spectral CT protocols and post-processing techniques.

The phantom consists of a removable/stand-alone head phantom (Ø 160 mm cylinder) with 10 holes (Ø 25 mm) to house different inserts and an oval (QRM-10150) or an optional circular (QRM-10151) body, equipped with 9 bores. Body and Head section are made of water-equivalent material (CTwater). 

The phantom is equipped with a set of 26 inserts including rods enriched with several contrast media (water+iodine, adipose+iodine) as well as calcium (water+calcium hydroxyapatite), each material with different concentrations. Additionally, water- and soft tissue-equivalent inserts (adipose, liver, brain - ICRU Report 44 and 46) are included. Mass density, concentration and electron density are provided for all materials.
