| Outline of Final Research Achievements |
Dental cone beam CT (CBCT) has many characteristics different from medical CT. For this reason, procedures of constancy tests for medical CT units are not directly applicable to those for dental CBCT units. The special and unique procedures should be devised. In this study, several phantoms dedicated to constancy tests for dental CBCT units were developed. Among those phantoms, the phantom for evaluation of voxel values seems the most important because existing phantoms have inherent problems.
