針對骨骼的骨礦物質(zhì)密度測定評估進(jìn)行HU vs. CaHA校準(zhǔn),并就其物理X射線衰減特性模擬真實(shí)的人類骨骼-羥基磷灰石鈣(CaHA)是人體骨骼的基本成分(65-70%CaHA)。
CTwater(一種等同于水的塑料)是與特定比例的CaHA混合的基本材料。 CaHA的濃度(骨礦物質(zhì)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.
