The aim of this paper is to provide access to a database consisting of the raw radio-frequency ultrasonic echoes acquired from malignant and benign breast lesions. The database is freely available for study and signal analysis.
The ultrasonic radio-frequency echoes were recorded from breast focal lesions of patients of the Institute of Oncology in Warsaw. The data were collected between 11/2013 and 10/2015. Patients were examined by a radiologist with 18 yr' experience in the ultrasonic examination of breast lesions. The set of data includes scans from 52 malignant and 48 benign breast lesions recorded in a group of 78 women. For each lesion, two individual orthogonal scans from the pathological region were acquired with the Ultrasonix SonixTouch Research ultrasound scanner using the L14-5/38 linear array transducer. All malignant lesions were histologically assessed by core needle biopsy. In the case of benign lesions, part of them was histologically assessed and another part was observed over a 2-year period.
The radio-frequency echoes were stored in Matlab file format. For each scan, the region of interest was provided to correctly indicate the lesion area. Moreover, for each lesion, the BI-RADS category and the lesion class were included. Two code examples of data manipulation are presented. The data can be downloaded via the Zenodo repository (https://doi.org/10.5281/zenodo.545928) or the website http://bluebox.ippt.gov.pl/~hpiotrzk.
The database can be used to test quantitative ultrasound techniques and ultrasound image processing algorithms, or to develop computer-aided diagnosis systems.
本文旨在提供一个由恶性和良性乳腺病变的原始射频超声回波组成的数据库。该数据库可供研究和信号分析使用。
超声射频回波是从华沙肿瘤研究所患者的乳腺局灶性病变中记录的。数据收集于 2013 年 11 月至 2015 年 10 月之间。检查由一位具有 18 年乳腺病变超声检查经验的放射科医生进行。该数据集包括来自 78 名女性的 52 个恶性和 48 个良性乳腺病变的扫描。对于每个病变，使用 Ultrasonix SonixTouch Research 超声扫描仪从病理区域采集两个单独的正交扫描，使用 L14-5/38 线性阵列换能器。所有恶性病变均经组织学评估采用核心针活检。良性病变中，一部分经组织学评估，另一部分观察了 2 年。
射频回波以 Matlab 文件格式存储。对于每个扫描，提供感兴趣区域以正确指示病变区域。此外，对于每个病变，还包括 BI-RADS 类别和病变类别。给出了两个数据处理的代码示例。可以通过 Zenodo 存储库（https://doi.org/10.5281/zenodo.545928）或网站 http://bluebox.ippt.gov.pl/~hpiotrzk 下载数据。
该数据库可用于测试定量超声技术和超声图像处理算法，或开发计算机辅助诊断系统。
