Classification: CPC A  G | IPC A  G

Claim 10:
11. The method of claim 8, wherein deriving a sensor pixel-to-standard-unit ratio using the selected at least one measurement process comprises:
determining one or more outer borders for respective one or more dental objects appearing in the source radiographic image data;
comparing the one or more outer borders to 2D projections in a projection dictionary, the 2D projections being at incremental distance and angles generated from 3D dental image data, to identify a match between the one or more outer borders and the 2D projections in the projection dictionary;
estimating a viewing angle at which the source radiographic image data was obtained based on the identified match between the one or more outer borders and the 2D projections in the projection dictionary; and
deriving the sensor pixel-to-standard-unit ratio based on the estimated angle at which the source radiographic image data was obtained.
