Pneumonia Chest X Ray

## Overview

Pneumonia Chest X Ray is a dataset for object detection tasks - it contains Pneumonia Nopneumonia annotations for 200 images.

## Getting Started

You can download this dataset for use within your own projects, or fork it into a workspace on Roboflow to create your own model.

  ## License

  This dataset is available under the [CC BY 4.0 license](https://creativecommons.org/licenses/CC BY 4.0).

The proposed dataset has been combined from three popular lung segmentation datasets: Darwin, Montgomery, and Shenzhen. The combined data allow researchers and clinicians to gain access to a good quality dataset, a large proportion of which has been manually annotated. The combined dataset consists of 6,810 images, with corresponding binary masks of lungs with the following distribution of images between the three datasets: • 6,106 images from the Darwin dataset; • 139 images from the Montgomery dataset; • 566 images from the Shenzhen dataset.

The Darwin dataset [1, 2] images include most of the heart, revealing lung opacities behind the heart, which may be relevant for assessing the severity of viral pneumonia. The lower-most part of the lungs, where visible, is defined by the extent of the diaphragm. Where present and not obstructive to the distinguishability of the lungs, the diaphragm is included up until the lower-most visible part of the lungs. A key property of this dataset is that image resolutions, sources, and orientations vary across the dataset, with the smallest image being 156x156 pixels and the largest being 5600x4700 pixels. Furthermore, we included the portable X-ray images which are of significantly lower quality as compared to standard X-rays. A key limitation of the Darwin dataset is that it does not contain lateral X-ray lung segmentations. It is worth noting that lung segmentations were performed by human annotators using Darwin's Auto-Annotate AI and then adjusted and reviewed by expert radiologists.

Both the Montgomery and Shenzhen datasets [3] were published by the United States National Library of Medicine and are made of posteroanterior chest X-ray images. These images are available to foster research in computer-aided diagnosis of pulmonary diseases with a special focus on pulmonary tuberculosis. The datasets were acquired from the Department of Health and Human Services (Maryland, USA) and Shenzhen №3 People's Hospital (Shenzhen, China). Both datasets contain normal and abnormal chest X-ray images with manifestations of tuberculosis and include associated radiologist readings.

This study aimed to systematically diagnose pneumonia directly from paediatric chest X-ray images using a computational framework. The project research goals were 1) to establish a high-quality dataset of pneumonia labelled X-ray images, 2) to extend existing deep learning architectures for pneumonia diagnoses, and 3) to construct a computational pipeline, enabling members of the broader community to interface with the computational models to diagnose pneumonia from X-ray images. The paediatric chest x-ray images were derived from 1) a WHO-supported surveillance study at Dhaka Shishu Hospital (DSH), from 2) a community site at Kumudini Women's Medical College (KWMCH), and from 3) the WHO Chest Radiography in Epidemiological Studies (WHO CRES) working group. The images were interpreted by at least two trained clinicians / radiologists for the presence of 1) primary end-point pneumonia (PEP), 2) other lung infiltrates, and/or 3) pleural fluid in either the left or right lung, for a total of six possible binary outcomes, which will henceforth be called 'labels'. A third reader resolved discordant PEP labels found between the first and second readers. An X-ray image were included in this study if 1) the age of the child for whom the X-ray was performed was <=59 months, 2) the X-ray was performed in one of the two study hospitals or from the WHO CRES reference image set, and 3) the image captured the lung area. Any Image that was marked 'uninterpretable' (features of the images were not interpretable with respect to presence or absence of PEP) by two readers were excluded. The deposited datasets contain the resulting labels from the multiple readers for each dataset described above.

Chest X-ray images are a critical diagnostic tool in the field of medicine, primarily used for the detection and monitoring of various lung diseases, including COVID-19 and pneumonia. These images offer a non-invasive way to visualize the internal structures of the chest, allowing medical professionals to identify abnormalities, lesions, or infections in the lungs. Lung diseases, such as pneumonia and COVID-19, are a significant global health concern. Understanding their prevalence and early detection are crucial in reducing morbidity and mortality associated with these conditions.

Mortality statistics worldwide underscore the importance of effective lung disease and COVID-19 detection. According to the World Health Organization (WHO), lung diseases are a leading cause of death, accounting for approximately 4 million fatalities annually. In the case of the COVID-19 pandemic, the timely detection and management of infected individuals can significantly impact the course of the disease and reduce its spread.

The "Chest X-Ray Image Dataset" is a valuable resource that aids in the diagnosis and research of lung diseases, including COVID-19. This dataset contains images collected from various hospitals in Bangladesh, where medical professionals have diligently monitored and gathered X-ray images for research and diagnostic purposes. It offers a total of 4,350 high-quality images, categorized into four distinct classes:

Normal (Class Distribution: 1200 Images): This category includes X-ray images of healthy lungs, serving as a reference for comparison with diseased or infected lungs.

Lung Opacity (Class Distribution: 1100 Images): These images represent cases with lung opacities or abnormalities that require further examination and diagnosis.

COVID (Class Distribution: 1050 Images): This class contains X-ray images of patients with confirmed or suspected cases of COVID-19, aiding in the early detection and monitoring of the disease.

Viral Pneumonia (Class Distribution: 1000 Images): X-ray images in this category are associated with viral pneumonia cases, assisting in the identification and understanding of this specific type of lung infection.

This dataset plays a vital role in the healthcare sector. It empowers medical professionals and researchers by providing a comprehensive collection of chest X-ray images to facilitate lung disease and COVID-19 detection. By using machine learning and deep learning techniques, this dataset can contribute to the development of automated diagnostic tools, aiding in faster and more accurate disease identification. The insights gained from this dataset can enhance patient care, reduce mortality rates, and play a pivotal role in the ongoing battle against lung diseases and COVID-19.
