Subjective quality assessment of computed radiography hand images

Quantitative assessment of computed radiography quality control parameters.

Quality controls for testing the performance of computed radiography (CR) systems have been recommended by manufacturers and medical physicists' organizations. The purpose of this work was to develop a set of image processing tools for quantitative assessment of computed radiography quality control parameters. Automatic image analysis consisted in detecting phantom details, defining regions of ...

Quality comparison of direct digital panoramic radiography and computed radiography panoramic

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

Breakthroughs in Radiography: Computed Radiography

CE Email comments/questions to [email protected], fax 800-556-3288, or log on to www.VetLearn.com Computed radiography (CR) is a digital imaging technology and digital x-ray image management system that has been used in human and veterinary medicine since the 1980s. CR helps eliminate many of the disadvantages of traditional radiography. A storage phosphor plate collects the pattern of x...

Quality assessment of orthodontic radiography in children.

OBJECTIVES Numbers of dental panoramic tomographs (DPTs) and lateral cephalometric radiographs (LCRs) outweigh other radiographic examinations in 7- to 12-year-old Finns. Orthodontists and general practitioners (GPs) involved in orthodontics hold therefore the highest responsibility of the exposure of children to ionising radiation with its risks. Against this background, lack of reports on the...
