Outline of Final Research Achievements

A dental cone-beam CT (CBCT) has been developed and widely used in dental clinic since the dental implant has become popular. However, it is impossible to measure the bone density by the dental CBCT because the dental CBCT does not have the CT value while it is possible to measure the bone density by the medical CT. Therefore, the bone density is to estimate from the pixel which gains from the image of the dental CBCT with no accuracy.
The purpose of this study is to develop the phantom which measures the bone density with accuracy.
