Radiograph preprocessing, based on the multiscale image contrast amplification (MUSICA) algorithm. a The MUSICA algorithm diagram with picture resolve, high-frequency enhancer, and image reconstruction. b Two radiographs from different machines. c The corresponding graphs processed by MUSICA. Compared to the raw data, the processed graphs have a more consistent image quality, especially the rib display. d Variance of the signal-to-noise ratio (SNR) of the images before and after MUSICA processing
