Ultrasound diagnosis is routinely used in obstetrics and gynecology for fetal biometry, and owing to its time-consuming process, there has been a great demand for automatic estimation. However, the automated analysis of ultrasound images is complicated because they are patient-specific, operator-dependent, and machine-specific. Among various types of fetal biometry, the accurate estimation of abdominal circumference (AC) is especially difficult to perform automatically because the abdomen has low contrast against surroundings, non-uniform contrast, and irregular shape compared to other parameters.We propose a method for the automatic estimation of the fetal AC from 2D ultrasound data through a specially designed convolutional neural network (CNN), which takes account of doctors' decision process, anatomical structure, and the characteristics of the ultrasound image. The proposed method uses CNN to classify ultrasound images (stomach bubble, amniotic fluid, and umbilical vein) and Hough transformation for measuring AC. We test the proposed method using clinical ultrasound data acquired from 56 pregnant women. Experimental results show that, with relatively small training samples, the proposed CNN provides sufficient classification results for AC estimation through the Hough transformation. The proposed method automatically estimates AC from ultrasound images. The method is quantitatively evaluated, and shows stable performance in most cases and even for ultrasound images deteriorated by shadowing artifacts. As a result of experiments for our acceptance check, the accuracies are 0.809 and 0.771 with the expert 1 and expert 2, respectively, while the accuracy between the two experts is 0.905. However, for cases of oversized fetus, when the amniotic fluid is not observed or the abdominal area is distorted, it could not correctly estimate AC.

从胎儿超声图像中测量头部生物特征对于监测胎儿的健康发育具有重要意义。然而,相关解剖结构的准确测量在临床中受到较大的观察者间差异的影响。为了解决这个问题,提出了一种利用全卷积网络(FCN)来确定胎儿头围(HC)和双顶径(BPD)测量值的自动化方法。在常规筛查检查期间,在头部的大约2000个2D超声图像上训练FCN,所述图像具有由45个不同的超声医师提供的注释,以执行头部的语义分割。椭圆被拟合到所得到的分割轮廓,以模仿通常由声谱仪操作员产生的注释。该模型的性能与观察者间的变异性进行了比较,其中两位专家手动注释了100张测试图像。HC的平均绝对模型专家误差略优于观察者间误差(1.99 mm vs 2.16 mm),BPD(0.61 mm vs 0.59 mm)以及Dice系数(0.980 vs 0.980)相当。我们的研究结果表明,该模型的性能与人类专家相似,并学会从由许多超声医师注释的大型数据集中产生准确的预测。此外,在GPU上以15 fps的速度近实时生成测量结果,这可以加快熟练和实习超声医师的临床工作流程。
