Digital technology provided by the GE flat panel detector allows a PA/AP chest exam to be performed almost simultaneously. Two images at different energy levels are acquired in less than 200 milliseconds. Three images are generated providing three separate views:

• routine radiographic image
• soft tissue image with the bones "subtracted"
• image of the bones and any calcified structures

In less than a few seconds, Dual Energy Subtraction can help to eliminate obstructions from overlying bones while providing additional information on calcifications in chest pathology studies.
