3D morphology and section images of placenta villi with GH via OCT. (a) Top view of 3D OCT morphology shows placental intermediate villi with GH are smaller in diameter and longer in length and the tree structure morphology characteristics of placenta with GH is different from the normal placenta, with more slender intermediate villi and fewer terminal villi which means poorly‐branched villous tree. (b) A representative OCT en‐face image of placenta villi with GH. (c) A representative rescaled B‐scan image of placental villi corresponding to the position indicated by the green line in (a). (d) A representative rescaled B‐scan image of placental villi corresponding to the position indicated by the blue dashed line in (a). All scale bars are 500 μm. GH, gestational hypertension; OCT, optical coherence tomography
