Photomicrographs of liver histology (A–C: Elastica-Masson staining, ×100; D–F: Binarized image, ×100; G: Quantification of liver fibrosis). The extent of fibrosis was quantified by binarizing to fibrous or not fibrous area using Win ROOF software (D: Untreated group; E: Shock wave group; F: Control group) in 10 microscopic fields (×100) per specimen in all rats. The quantified fibrous area was averaged for each group (G).
