Mindways Software k 2 hpo 4 calibration phantom
Density calibration methods for QCT image analysis. (a) Phantom calibration. K2HPO4 can be seen at the base of the image. Each rod is manually segmented 10 slices from each end and then interpolated (ITK‐SNAP) to establish the linear conversion between HU and <t>K</t> <t>2</t> <t>HPO</t> <t>4</t> density using the highest (teal) and lowest (red) densities . (b) Internal calibration. Referent tissues of air (yellow), adipose (red), and skeletal muscle (teal) were segmented manually at the level of the proximal humerus. Cortical bone (blue) was thresholded to determine the highest HU value (which is essential for establishing the HU‐density conversion).
K 2 Hpo 4 Calibration Phantom, supplied by Mindways Software, used in various techniques. Bioz Stars score: 86/100, based on 1 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and more

Techniques Used:

Comparing calibration techniques. (a) Linear regression showing correlation between vBMD (mgK 2 HPO 4 /cm 3 ) from internal calibration according to tissue combination relative to phantom calibration ( n = 39). (b) Bland–Altman plot for vBMD (mgK 2 HPO 4 /cm 3 ) for internal calibration according to tissue combination relative to phantom calibration ( n = 39).
