Brain Hemorrhage Extended (BHX): Bounding box extrapolation from thick to thin slice CT images

BHX is a public available dataset with bounding box annotations for 5 types of
acute hemorrhage as an extension of the qure.ai CQ500 dataset. This dataset
intends to provide data resources to help advance hemorrhage detection towards
machine learning localization tasks.

**Key Points: **

* BHX contains up to 39,668 bounding boxes in 23,409 images annotated for hemorrhage, out of a total of ~170k images from qure.ai CQ500 dataset.

* The dataset was built through an efficient method to obtain automatic annotated images (thin slices) from sparse initial labeling (thick slices).

* We hope this dataset can contribute to further develop and validate machine learning algorithms, ultimately helping to diagnose intracranial hemorrhage.

背景概述

Brain Hemorrhage Extended (BHX) 是一个公开的脑出血CT图像数据集，扩展自qure.ai CQ500数据集，包含5种急性出血类型的边界框标注，总计39,668个边界框分布在23,409张图像中。该数据集通过高效方法从厚切片手动标注外推到薄切片，旨在支持机器学习算法在出血检测和定位任务中的开发和验证。
