QRM人体骨骼等效材料是在物理X射线衰减特性方面模仿真实人体骨骼的材料

模仿人体骨骼的固体材

可提供不同形状和浓度的羟基磷灰石钙（CaHA）

羟基磷灰石钙（CaHA）是人体骨骼的基本成分（ 40％CaHA）。

材料应用：

骨校准骨密度测量

拟人化模型中的骨骼（脊柱，臀部等）

冠状动脉中的钙栓塞和狭窄

高衰减球。

与特定比例的CaHA混合的基础材料可以组织当量或脂肪的形式获得。

可以使用不同密度的CaHA或指定的CT值HU。

羟基磷灰石钙（CaHA）的浓度

用于CT：0-1000 mg HA /cm3

适用于Micro-CT：0-1200 mg HA /cm3


针对骨骼的骨矿物质密度测定评估进行HU vs. CaHA校准，并就其物理X射线衰减特性模拟真实的人类骨骼-羟基磷灰石钙（CaHA）是人体骨骼的基本成分（65-70％CaHA）。CTwater（一种等同于水的塑料）是与特定比例的CaHA混合的基本材料。 CaHA的浓度（骨矿物质密度）不同。

For the HU vs. CaHA calibrations with respect to Bone Mineral Densitometry evaluation of bones and to mimic real human bone with respect to its physical X-ray attenuation properties，Calcium Hydroxyapatite (CaHA) is the basic component of human bone (65 - 70% CaHA).

It is predestinated for the following applications:

1、 bone mineral density calibration
2、 bone density measurements
3、 bone (spine, hip, etc.) in anthropomorphic phantoms
4、 Ca-plugs and stenosis in coronary arteries
5、 high attenuating spheres.


CTwater (a water equivalent plastic) is the basic material which is mixed with the specific fraction of CaHA. Different concentrations (bone mineral densities) of CaHA are available.


Application range of QRM-Bone:

- bone calibration
- bone density measurements
- bone (spine, hip, etc.) in anthropomorphic phantoms
- Ca-plugs and stenosis in coronary arteries
- high attenuating spheres
- and many others

The basic material (which is mixed with the
specific fraction of CaHA) is available as ?
CTWater , tissue equivalent, or fat.
Many densities of CaHA (or specified CT-values
HU) are available upon request.
