FETAL_PLANES_DB: Common maternal-fetal ultrasound images

A large dataset of routinely acquired maternal-fetal screening ultrasound images collected from two different hospitals by several operators and ultrasound machines. All images were manually labeled by an expert maternal fetal clinician. Images are divided into 6 classes: four of the most widely used fetal anatomical planes (Abdomen, Brain, Femur and Thorax), the mother’s cervix (widely used for prematurity screening) and a general category to include any other less common image plane. Fetal brain images are further categorized into the 3 most common fetal brain planes (Trans-thalamic, Trans-cerebellum, Trans-ventricular) to judge fine grain categorization performance. Meta information (patient number, us machine, operator) is also provided, as well as the training-test split used in the Nature Sci Rep paper.本数据集为多操作人员、多超声成像设备于两家不同医院采集的常规孕产妇-胎儿筛查超声影像大型数据集。所有影像均由资深产科胎儿超声临床专家完成人工标注。影像共分为6大类：4类为临床应用最广泛的胎儿解剖切面（腹部(Abdomen)、脑部(Brain)、股骨(Femur)和胸部(Thorax)），1类为用于早产筛查的孕妇宫颈(Cervix)切面，剩余1类为通用类别，涵盖其余所有少见影像切面。胎儿脑部影像还将进一步细分为3类最常用的胎儿脑部切面：经丘脑切面(Trans-thalamic)、经小脑切面(Trans-cerebellum)及经侧脑室切面(Trans-ventricular)，用于评估细粒度分类任务的模型性能。数据集同时提供元数据信息，包括患者编号、超声设备及操作人员信息，同时附带《自然·科学报告》（Nature Sci Rep）论文中采用的训练集与测试集划分方案。
