Flat Panel Detectors in Industrial Radiography

Real time imaging in the field of industrial radiography arrived over half a century ago and even before that in medical radiography. All the progress in the field for first 30 – 35 years produced analog images. Digital images have come only recently. Fluorescent screens, proximity focus intensifier and then electromagnetically focused Image Intensifier produced real time images in analog. They...

Two Heads Are Better Than One, but How Much?

Many theories of causal learning and causal induction differ in their assumptions about how people combine the causal impact of several causes presented in compound. Some theories propose that when several causes are present, their joint causal impact is equal to the linear sum of the individual impact of each cause. However, some recent theories propose that the causal impact of several causes...

Practical expressions describing detective quantum efficiency in flat-panel detectors

In radiology, image quality excellence is a balance between system performance and patient dose, hence x-ray systems must be designed to ensure the maximum image quality is obtained for the lowest consistent dose. The concept of detective quantum efficiency (DQE) is widely used to quantify, understand, measure, and predict the performance of x-ray detectors and imaging systems. Cascaded linear-...

Direct-conversion flat-panel X-ray image detectors

Flat-panel X-ray image detectors have been shown to be suitable to replace the conventional X-ray filmjscreen cassettes for medical radiography (static or snapshot imaging). They are capable of capturing the X-ray image digitally immediately after the X-ray exposure which permits a convenient clinical transition to digital radiography. There are two general approaches to the flat-panel X-ray de...
