RADIOGRAPHIC QUANTITATION METHOD FOR ASSESSING PERIODONTAL BONE LOSS

摘要

A system and method for measuring a bone deformity,in particular bone density loss, includes steps of obtaining at least two images of a bone area to be analyzed over a period of time; registering each obtained sequential images against each other to form registered image sets; calibrating each of the registered image sets; outlining the area of bone to be analyzed for deformity; generating bone reactivity score for the outlined area in each registered image set; and, transforming the pixel intensity values in the outlined area to correct for non-linearities. Each mean pixel intensity value obtained for each registered image set over a time period may be analyzed to accurately determine any deformity in said bone area.
