Comparison of image quality and radiation dose between an image-intensifier system and a newer-generation flat-panel detector system — technical phantom measurements and evaluation of clinical imaging in children.

Background: Many image-intensifier fluoroscopy systems have been replaced by flat-panel detectors in recent years.

Objective: To compare the level of contrast, image resolution and radiation dose between an image-intensifier and a newer-generation flat-panel detector system in a pediatric radiology unit.

Materials And Methods: We compared two systems — a conventional image intensifier and a newer-generation flat-panel system.
