Improved digital chest tomosynthesis image quality by use of a projection-based dual-energy virtual monochromatic convolutional neural network with super resolution
Fig 12
Plots of the radial Modulation Transfer Function (radial MTF) versus spatial frequency (cycles/mm) from the in-focus plane for the Dual-Energy (DE) Virtual Monochromatic (VM) with Very-Deep Super-Resolution (VDSR) reconstruction algorithm (DE–VM–VDSR) with and without BF and conventional reconstruction algorithms.
The spatial frequency of the simulated ground-glass opacity (GGO) nodule area indicates the simulated GGO nodule and background areas of the radial MTF measurements. The plots are of the area of the GGO nodule and background regions.
