Evaluation of the ultrasound biomicroscopic system with gelatin phantoms. (a,b) Graphs of the mean displacements of the gelatin phantoms with YM of 0.94 ± 0.5 kPa and 7.51 ± 0.5 kPa under each excitation condition (n = 10). (c) Box and whisker plot of the displacements of gelatin phantoms at different YM corresponding to the T-stages of cancer (n = 10). The red lines indicate the median values whereas the marks, ‘x’ indicate the mean values (d,e) High-frequency B-mode and ARFI images of bilayer gelatin phantoms in the lateral direction. (f) Lateral resolution measured in a point-spread function constructed at the boundary between two layers. (g,h) High-frequency B-mode and ARFI images of bilayer gelatin phantoms in the axial direction. (i) Axial resolution measured in a point-spread function constructed at the boundary between two layers.
