Abstract:
:To evaluate the efficacy of AMBER, a multiple-beam equalization system for chest radiography, the authors performed a nodule detection study using an anthropomorphic chest phantom. AMBER and conventional images were compared. The images were read by four observers, and analysis was done by means of modified receiver-operating characteristic (ROC) curves (free ROC curves [FROC]). The results of the FROC analysis show a significant increase in the detectability of nodules (P less than .001) projected over the mediastinum with the use of AMBER. No significant difference between AMBER and conventional images was noted in detectability of nodules projected over the lung.

RADIOLOGY文献大全abstract::Anti-scatter grids reduce the amount of secondary radiation contributing to the image and improve the signal-to-noise ratio. However, they may also lead to the creation of linear artifacts representing the shadows of the radiopaque septa. Grid motion perpendicular to the septa during the exposure can cause blurring of...
