The XtremeCT II is the new generation high resolution peripheral quantitative computed tomography (HR-pQCT).
The XtremeCT II is designed to measure the bone density and to quantify the threedimensional microarchitecture of the bone at the distal tibia and radius of humans for clinical in vivo assessment of osteoporosis at an even higher precision and speed than its predecessor, the XtremeCT.
A low X-ray dose allows regular follow-up measurements and powerful true-3D evaluation software automatically matches cortical and trabecular bone regions to previous measurements for direct comparison of density and structure characteristics.
Density Parameters - Structural Parameters
Cortical Density - Trabecular Thickness
Trabecular Density - Trabecular Separation
- Trabecular Number
- Volume Fraction
- Cortical Thickness
- Cortical porosity
For compatibility with the previous generation HR-pQCT, a XtremeCT equivalent protocol is available. A video provided by our customers at the Bone Imaging Laboratory in Calgary shows how the XtremeCT is used in practice.
