Exposure and dose in panoramic radiology.

Abstract

Panoramic radiology entrance skin exposure (ESE) was measured for a Siemens Orthopantomograph 10 E using a thimble chamber and TLDs. Thimble chamber measurements are shown to be inaccurate for the moving, narrow beam panoramic scan geometry due to partial volume and partial charged-particle equilibrium effects. For 75 KVp, 8 mA panoramic scans the TLD… (More)
