We report in vitro and in vivo trials of K-edge fluoroscopy, by which iodine contrast concentration is displayed live, with tissue and bone images suppressed, free of patient-motion artifacts. Iodine and cerium, 125 and 225 mg/cm2 respectively, filte

We have been testing a digital beam attenuator (DBA) system for fabricating patient-specific compensating filters to improve image quality in chest radiography. At present, the technique is limited by a 2 hour attenuator fabrication time and a 20 mR
