digital radiography


Artifacts: Digital – Computed Radiography (CR) / phosphor plates

Increased density E (increased exposure to x rays) E =↑ Exposure (x rays) This occurs when the phosphor plate is overexposed (i.e. using a molar setting for an anterior radiograph). Increased density due to incorrect time setting. Decreased density E (decreased exposure to x rays) E (increased exposure to visible […]


Artifacts: Digital – Digital Radiography (DR) / sensors

The entire acronym of DEBT does not apply to both digital radiography (DR) and computed radiography (CR) systems.  Since both systems are a little different with artifacts I have broken them up into two separate posts. Increased density E (increased exposure to x rays) E =↑ Exposure (x rays) This […]


ROC curves in Dentistry

This week I’m focusing on ROC curves in dentistry and the different imaging modalities (primarily film versus digital).  As these numbers can change based on the research being performed and the reviewers of those radiographs, I thought the best way to break this all down is to give a short […]
