Tpw. Derooij et al., APPLICATION OF AMBER IN SINGLE-ENERGY AND DUAL-ENERGY DIGITAL IMAGING- IMPROVEMENT IN NOISE-LEVEL AND DISPLAY DYNAMIC-RANGE, Radiographics, 14(2), 1994, pp. 407-414
The combination of computed radiography (CR) and advanced multiple bea
m equalization radiography (AMBER) was evaluated for both single- and
dual-energy chest radiography. The improved signal-to-noise ratio foun
d with CR and AMBER resulted in a better visualization of structures i
n the mediastinum and basal lung than that found with CR alone. For th
e central lung, no improvement was seen. Because of the compressed dyn
amic range with CR and AMBER, contrast on hard copies and video monito
rs could be high without a sacrifice in image latitude. Dual-energy im
ages showed a considerably lower noise level. The combined use of AMBE
R and CR promises to overcome the dynamic range limitations of digital
displays while improving signal-to-noise ratio.
