Clinical Echocardiogram Dataset

该数据集包含了2086张二维胎儿心超四腔心视图，这些图像来自于19至45岁的孕妇，孕期为18至39周。这些图像使用离线椭圆标注工具由两位受过培训的操作员进行标注，并由胎儿心超专家进行审核。该数据集的任务是对心脏和胸腔区域进行检测，并测量心肺比（CTR）和心脏轴线。

This dataset comprises 2086 2D fetal echocardiographic four-chamber view images, sourced from pregnant women aged 19 to 45 years with gestational ages spanning 18 to 39 weeks. These images were annotated by two trained operators using an offline elliptical annotation tool, and reviewed by fetal echocardiography experts. The task of this dataset is to detect cardiac and thoracic regions, and measure the cardiothoracic ratio (CTR) and cardiac axis.
