Hydrops Fetalis is an abnormal condition in the fetus by an accretion of unusual fluid or edema in two or more fetal cavities for instance ascites, pericardial and pleural effusion. Accumulation of atypical fluid above 2 mm needs extra attention of radiologists. Ultrasound imaging technique helps to diagnose the fluid accumulation within the pericardial tissues. The trained medicinal practitioners also find difficult to analyse the hydrops due to the low assessment gray scale ultrasound images. The segmentation of hydrops fetalis from the fetal heart ultrasound image helps the sonographists and pediatrists to diagnose easily and effectively at the early stage itself. The low quality and poor resolution ultrasound image, make the segmentation process difficult. We use the spatially constrained-distance regularized level set evolution algorithm for segmenting the hydrops region.

超声胎儿心脏图像中胎儿水肿的空间受限距离正则化水平集演化方法

胎儿积水是胎儿的一种异常状况，因为在两个或多个胎儿腔中积聚了异常液体或水肿，例如腹水，心包和胸腔积液。超过2毫米的非典型液体的积聚需要放射科医生特别注意。超声成像技术有助于诊断心包组织内的液体积聚。由于低评估灰度超声图像，训练有素的医学从业人员还发现难以分析积液。胎儿心脏超声图像对胎儿积水的分割有助于超声医师和儿科医生在早期阶段轻松有效地进行诊断。低质量且分辨率差的超声图像使分割过程变得困难。
