Fig. 4. Optoacoustic quality guidance of autologous fat transfer using BayROM.

(A) Image comparisons of large FOVs, i.e., 4.5 mm by 4.5 mm (left column), and small FOVs, i.e., 1 mm by 1 mm (right column), of CELT^plus imaged using full raster scanning (GT) and BayROM (92.5% data reduction). The average RMSE and the average PSNR between GT and BayROM are 39.28 μV and 22.63 dB for the FOVs, and 13.27 μV and 31.04 dB for the small FOVs. (B) Image comparisons of large FOVs, i.e., 4.5 mm by 4.5 mm (left column), and small FOVs, i.e., 1 mm by 1 mm (right column), of nanofat imaged using full raster scanning (GT) and BayROM. The RMSE and the average PSNR between GT and BayROM are 34.15 μV and 26.67 dB for the large FOVs, and 11.25 μV and 32.62 dB for the small FOVs. (C and D) Intensity distributions of lipid and protein signals in large FOV images of CELT^plus obtained using full raster scanning (GT) and BayROM. (E and F) Intensity distributions of lipid and protein signals in large FOV images of nanofat obtained using full raster scanning (GT) and BayROM.
