Download2006
Carey, Jason, Lagravère, Manuel O., Major, Paul W., Fang, Y., Packota, Garnet V., Toogood, Roger W.
Objective: The purpose of this study was to determine a conversion coefficient for Hounsfield Units (HU) to material density (g cm−3) obtained from cone-beam computed tomography (CBCT-NewTom QR-DVT 9000) data. Methods: Six cylindrical models of materials with different densities were made and...

Objectives: The purpose of this study was to determine the effect of an object's location in a cone beam CT imaging chamber (CBCT-NewTom 3G) on its apparent density and to develop a linear conversion coefficient for Hounsfield units (HU) to material density (g cm−3) for the NewTom 3G Scanner....
