Improved digital chest tomosynthesis image quality by use of a projection-based dual-energy virtual monochromatic convolutional neural network with super resolution
Fig 5
Differences in simulated GGO nodule detection on polychromatic and Virtual Monochromatic (VM) projection-based images.
The visibility of the simulated GGO nodule in the projection image is improved by performing UM. The upper row shows the projection image (with/without UM), whereas the lower row shows the global image threshold using Otsu’s method.
