Table 1 Structural bone parameters calculated from µCT data, with abbreviations, base units and definitions.
From: Iterative and discrete reconstruction in the evaluation of the rabbit model of osteoarthritis
Parameter | Unit | Definition | |
|---|---|---|---|
Subchondral bone plate | |||
Plate thickness | (Pl.Th) | µm | Average thickness of the subchondral bone plate |
Trabecular bone | |||
Bone volume fraction | (BV/TV) | % | Number of pixels classified as bone divided by total amount of pixels |
Trabecular thickness | (Tb.Th) | µm | Mean thickness of trabeculae |
Trabecular separation | (Tb.S) | µm | Mean thickness of the spaces between trabeculae |
Trabecular number | (Tb.N) | mm−1 | Linear density of trabeculae, i.e. amount of trabeculae per unit length |
Ellipsoid factor | (EF) | (a.u.) | Measures the anisotropy in the data by determining how prolate (rod-like) or oblate (plate-like) the trabeculae are in the sample. Negative EF values correspond to prolate and positive values to oblate dominancy in the geometry. |
