“…This disease seriously compromises maternal and child health and is one of the leading causes of morbidity and mortality in pregnant women and perinatal children. Therefore, early detection and assessment of fetal cardiac function are paramount to guide clinical assessment of the condition for further treatment [ 6 ]. Echocardiography is a common modality for the structural and functional examination of the heart, with simple operation and good repeatability, which allows an efficient assessment of the fetal cardiac function and provides a reference basis for early detection of cardiac developmental abnormalities [ 7 , 8 ].…”

Pregnancy-induced hypertension syndrome (PIH) is a common pregnancy syndrome that could cause varying degrees of maternal and fetal organic damage and even endanger their lives. This study aimed to investigate ultrasound of fetal cardiac function changes in PIH. Totally 40 cases of gestational hypertension admitted to Cangzhou Central Hospital between October 2018 and September 2019 were enrolled in the hypertension group, and 40 women with healthy pregnancies during the same period were assigned to the normal group. Ultrasound results showed that PIH was associated with a significantly higher fetal cardiac septal thickness, fetal left ventricular end-diastolic area and end-systolic area, fetal right ventricular end-diastolic area and end-systolic area, fetal left ventricular systolic fraction 1 (VSF1), fetal left ventricular systolic fraction 2 (VSF2), fetal right VSF1, and fetal right VSF2 versus healthy pregnancy. The PIH fetuses had significantly lower neonatal weights versus healthy fetuses. Newborns of hypertensive pregnancies have larger hearts, faster heart rates, increased cardiac contractility, and lower weights versus newborns of healthy pregnancies.

A thin, flexible, and biocompatible medical ultrasonic transducer was developed using a sok-gel composite spray technique to fabricate a single sheet of piezoelectric material. The careful selection of materials prioritized flexibility, with silicone rubber being chosen for its biocompatibility as the material to be in direct contact with the living body. A porous lead zirconate titanate (PZT) film with a dielectric constant of 134 was generated, and comb-shaped electrodes were printed on the piezoelectric film to form a 64-channel linear array, which successfully suppressed crosstalk values between adjacent elements and at a distance of two elements to -41.5 and -45.8 dB, respectively. Experiments using string targets achieved a spatial resolution of 2 mm in the lateral direction and 0.68 mm in the axial direction. In an imaging experiment of the carotid artery, the transducer was successful in visualizing the vessel wall before and after the carotid artery vessel.

“…Finally, the estimation model takes into account the increasing transformation of carcinogenic tissues. For shape estimation using ultrasonic images, a mathematical model [ 35 ] is proposed. The tumor location is combined with an ultrasonic array in this model to extract breast mass information from the image.…”

Dilated Semantic Segmentation for Breast Ultrasonic Lesion Detection Using Parallel Feature Fusion

Breast cancer is becoming more dangerous by the day. The death rate in developing countries is rapidly increasing. As a result, early detection of breast cancer is critical, leading to a lower death rate. Several researchers have worked on breast cancer segmentation and classification using various imaging modalities. The ultrasonic imaging modality is one of the most cost-effective imaging techniques, with a higher sensitivity for diagnosis. The proposed study segments ultrasonic breast lesion images using a Dilated Semantic Segmentation Network (Di-CNN) combined with a morphological erosion operation. For feature extraction, we used the deep neural network DenseNet201 with transfer learning. We propose a 24-layer CNN that uses transfer learning-based feature extraction to further validate and ensure the enriched features with target intensity. To classify the nodules, the feature vectors obtained from DenseNet201 and the 24-layer CNN were fused using parallel fusion. The proposed methods were evaluated using a 10-fold cross-validation on various vector combinations. The accuracy of CNN-activated feature vectors and DenseNet201-activated feature vectors combined with the Support Vector Machine (SVM) classifier was 90.11 percent and 98.45 percent, respectively. With 98.9 percent accuracy, the fused version of the feature vector with SVM outperformed other algorithms. When compared to recent algorithms, the proposed algorithm achieves a better breast cancer diagnosis rate.
