The feasibility of producing patient-specific beam attenuators for chest radiography has been investigated using an anthropomorphic phantom and a human volunteer. A low-dose test exposure is digitized, processed, and used to print a small cerium filt

Although image quality in chest radiography can be improved dramatically with compensating attenuators, it is difficult to match attenuator geometry to that of the patient and to properly position the filter in the x-ray beam. We are developing a sys

Since the early 1970's, Edholm and others have shown that compensation attenuators can provide fundamental improvements in radiographic image formation by modifying patient dose-distribution, reducing scatter fractions in dark regions of the image, a

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
