METHOD FOR ESTIMATING OSTEOGENESIS INTENSITY Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves applying computer-aided processing of general plan survey X-ray films with one or several zones of interest being detected on digitalized image corresponding to the number of osteogenesis foci. Quantitative osteogenesis intensity estimate is obtained by applying test grid and interpreting ratio of areas corresponding to distraction regenerate mineralization degree. Boundaries are determined in each zone of interest for delimiting intensity ranges characterizing tissue mineralization degrees at osteogenesis stages and reference points are marked. The first reference point is selected on proximal bone fragment end turned to diastasis. Lower boundary line of the proximal test grid, composed of parallel lines being perpendicular to long bone axis, is superposed with the first reference point. The second one is selected on distal bone fragment end turned to diastasis and the upper line of the distal test grid is superposed with it. Every region belonging to a zone of interest confined by neighboring test grid lines is segmented within the scope of established boundaries into intensity ranges and intensity range area shares in the total area of each region belonging to zone of interest. The intensity range area share proportions are used for estimating osteogenesis intensity.

EFFECT: wide range of functional applications.
