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 […]

Digital radiography: Detector Sensitivity

This last post on digital radiography is on detector sensitivity.  This is probably the most talked about characteristic of digital radiography when the systems are being hyped.  Detector sensitivity is the ability of the sensor/phosphor plate to respond to small amounts of radiation.  There is no term used to measure […]
