Medical Image Enhancement Algorithm for B-Mode Ultrasound Image Analysis of Neonatal Respiratory Distress Syndrome

The aim of this paper was to explore the imaging characteristics of lung B-ultrasound images under image enhancement algorithm for neonatal respiratory distress syndrome (NRDS) and the therapeutic effect of vitamin A (VA) on NDRS. 30 newborn babies with NRDS in hospital were selected as the experimental group and 30 healthy newborn babies were selected as the control group. All of them received the lung B-ultrasound based on the image enhancement algorithm under the partial differential equation (PDE). The subjects of the control group were given formula milk every day. On the basis of formula milk, the subjects of the experimental group took VA soft capsule orally once a day at noon. Oxidative stress indexes, blood gas indexes, and mechanical ventilation parameters were recorded in the subjects of the two groups. The results of 30 newborn babies with NRDS in the experimental group indicated that the images of 12 cases presented the disappearance of line A and dense or discontinuous distribution of line B; the abnormal pleural line was found in the images of 8 cases; there was lung consolidation under the pleural line, patchy hypoecho, and point-strip hyperecho in the images of 5 cases; the images of 2 cases showed alveolar edema and alveolar interstitial syndrome. Compared with before treatment, the arterial partial pressure of oxygen (PaO2) of subjects in the experimental group (87.61 ± 5.79) increased dramatically, but their arterial partial pressure of carbon dioxide (PaCO2) decreased sharply after treatment (40.07 ± 6.12), with statistically huge differences (P
