A new 2.5 D representation for lymph node detection in CT (CT Lymph Nodes)

This collection consists of Computed Tomography (CT) images of the mediastinum and abdomen in which lymph node positions are marked by radiologists at the National Institutes of Health, Clinical Center. Radiologists at the Imaging Biomarkers and Computer-Aided Diagnosis Laboratory labeled a total of 388 mediastinal lymph nodes in CT images of 90 patients and a total of 595 abdominal lymph nodes in 86 patients. The collection is aimed at the medical image computing community for developing and assessing computer-aided detection methods. Automated detection of lymph nodes can be an important clinical diagnostic tool but is very challenging due to the low contrast of surrounding structures in CT and to their varying sizes, poses, shapes and sparsely distributed locations. This data set is made available to make direct comparison to other detection methods in order to advance the state of the art.

背景概述

该数据集是一个用于CT图像中淋巴结检测的医学影像集合，包含来自176名患者的纵隔和腹部CT图像，其中由放射科医生标记了983个淋巴结位置（388个纵隔淋巴结和595个腹部淋巴结）。它旨在为医学图像计算社区提供资源，以开发和评估计算机辅助检测方法，并促进与其他方法的直接比较，以应对淋巴结检测在低对比度、多变大小和稀疏分布方面的挑战。
