Introduction #

Walid Al-Dhabyani, Mohammed Gomaa, Hussien Khaledet al.

The authors of the Breast Ultrasound Images Dataset address breast cancer, a leading cause of mortality among women globally, emphasizing the importance of early detection for reducing fatalities. The dataset pertains to medical images obtained through ultrasound scans for breast cancer assessment.

The data collection process involved gathering baseline ultrasound images of breasts from women aged between 25 and 75 years. This data accumulation was conducted in the year 2018, encompassing a total of 600 female patients. The dataset comprises 780 images, each with an average size of 500 Γ— 500 pixels, and is stored in PNG format. The images are systematically divided into the three classes: normal, benign, and malignant.

The procedure for dataset collection involved capturing grayscale ultrasound images, which were stored in DICOM format at Baheya hospital. This comprehensive endeavor, including image collection and annotation, spanned approximately a year. Initially, 1100 images were gathered; however, following data preprocessing, the dataset was refined to 780 images. To eliminate redundant information and improve the dataset quality, radiologists from Baheya hospital reviewed and corrected erroneous annotations. LOGIQ E9 ultrasound systems and LOGIQ E9 Agile ultrasound systems were employed for image acquisition, producing images with a resolution of 1280 Γ— 1024. The transducers utilized were 1–5 MHz on an ML6-15-D Matrix linear probe.

After data collection, preprocessing was executed to enhance dataset utility. Duplicate images were removed, and incorrect annotations were rectified through expert radiologist review. Conversion from DICOM to PNG format was achieved utilizing a DICOM converter application. Refinement procedures led to a reduction in the dataset size, resulting in 780 ultrasound images. To enhance dataset quality, images were cropped to different sizes, effectively eliminating extraneous boundaries. Fast photo crops facilitated this cropping process. The inclusion of image annotation into the image name was performed, and rigorous validation by Baheya hospital radiologists ensured data integrity.

Ground truth annotation plays a pivotal role in enhancing the dataset’s utility. This annotation was carried out using Matlab, where a freehand segmentation technique was employed for each image.

Summary #

Breast Ultrasound Images is a dataset for semantic segmentation and classification tasks. It is used in the medical industry.

The dataset consists of 780 images with 647 labeled objects belonging to 2 different classes including benign and malignant.

Images in the Breast Ultrasound Images dataset have pixel-level semantic segmentation annotations. There are 133 (17% of the total) unlabeled images (i.e. without annotations). There are no pre-defined train/val/test splits in the dataset. Alternatively, the dataset could be split into 3 classification sets: benign (437 images), malignant (210 images), and normal (133 images). The dataset was released in 2021 by the Cairo University, Egypt.

Co-occurrence matrix #

Co-occurrence matrix is an extremely valuable tool that shows you the images for every pair of classes: how many images have objects of both classes at the same time. If you click any cell, you will see those images. We added the tooltip with an explanation for every cell for your convenience, just hover the mouse over a cell to preview the description.

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Object distribution #

Interactive heatmap chart for every class with object distribution shows how many images are in the dataset with a certain number of objects of a specific class. Users can click cell and see the list of all corresponding images.
