2D Bone microarchitecture - QTS Score


Quibim has developed a noninvasive post-processing module that characterizes the trabecular bone microarchitecture by providing bone volume percentage, trabecular thickness, separation and irregularity analysis. These imaging biomarkers are combined in a single score, the Quality of a Trabecular Structure (QTS) score, which allows to identify initial deterioration and assess treatment response with high sensitivity.
