The 3D 8 x 8 cm image size is optimal for most diagnostic applications that require the whole dentition, mandible, and maxilla in the same volume. The 8 x 5 cm volume can be used for single views of the mandible or maxilla, lowering the radiation by almost 40%. The small 4 x 5 cm volume is intended for molar area studies or planning 3rd molar extractions. The volumes can also be blended together to generate an image up to 14.4 cm x 10. 5 cm x 8 cm horizontally and 8 cm x 8 cm x 13 cm vertically.
