Figure 1. Images of nodules in one of the human subjects. (a) Coned view of digital PA radiograph shows one clearly visible right lung nodule (arrow).
|(b) Tomosynthesis image shows the same nodule (vertical arrow) as seen on the PA radiograph in (a). A second nodule (horizontal arrow) is also visible that was not seen in the PA radiograph in (a).|
|(c) Tomosynthesis image at a more posterior level shows an additional left lung nodule (arrow) not seen in the PA radiograph in (a).|
|(d) CT image (lung window) confirms left lower lobe nodule seen in (c). (From Medical Physics 5:2554-2557, 2008)|
