The system enables quantification of bone loss by measuring its amount both inside and outside of the tooth of interest, and visualization of the 3-D shape and quantification result of the lesions. Experimental results in two cases of 3-D dental CT images and comparisons of the results confirmed that the system gives satisfying results, including less than 0.4mm of bone loss depth measurement (Virtual Probing)error and fairy intuitive presentation of the measurement results.}, pages = {63--64}, publisher = {INTELLIGENT MEDIA INTEGRATION NAGOYA UNIVERSITY / COE}, title = {MEASUREMENT OF BONE LOSS BY THREE-DIMENSIONAL IMAGE PROCESSING FOR ASSESSMENT OF PERIODONTITIS}, year = {2006} }
