SIIM-ACR Pneumothorax Segmentation 2019

Introduction #

Released 2019-01-25 ·Anna Zawacki, Carol Wu, George Shihet al.

SIIM-ACR Pneumothorax Segmentation 2019 is a dataset for SIIM-ACR Pneumothorax Segmentation Challenge. It is a critical competition focused on detecting pneumothorax in chest radiographic images. Pneumothorax, the accumulation of air between the lung and chest wall, can be life-threatening. This challenge aims to develop AI algorithms that classify and segment pneumothorax. Organized by the Society for Imaging Informatics in Medicine (SIIM), it seeks to improve early diagnosis using chest X-rays.

Pneumothorax, a condition where air accumulates in the space between the lung and chest wall, can be caused by various factors, including injuries, underlying lung diseases, or even seemingly inexplicable events. In some cases, it can pose life-threatening risks.

This challenge aims to harness the power of artificial intelligence to aid in the early and accurate diagnosis of pneumothorax, which is typically confirmed by radiologists through chest X-rays. Detecting pneumothorax can be challenging, and an effective AI algorithm could have widespread clinical applications. It could help prioritize the interpretation of chest radiographs, provide more confident diagnoses, and potentially save lives.

Authors are striving to achieve two primary objectives: firstly, to forecast the presence of pneumothorax within test images, and secondly, to delineate both the precise location and the extent of this medical condition through the use of masks.

Summary #

SIIM-ACR Pneumothorax Segmentation 2019 is a dataset for semantic segmentation and classification tasks. It is used in the medical industry.

The dataset consists of 12047 images with 2669 labeled objects belonging to 1 single class (pneumothorax).

Images in the SIIM-ACR Pneumothorax Segmentation 2019 dataset have pixel-level semantic segmentation annotations. There are 9378 (78% of the total) unlabeled images (i.e. without annotations). There are 2 splits in the dataset: train (10675 images) and test (1372 images). Alternatively, the dataset could be split into 2 classification image sets: pneumo_negative (9378 images) and pneumo_positive (2669 images). Also, the dataset contains image id and pneumo_positive, pneumo_negative tags. The dataset was released in 2019 by the The Society for Imaging Informatics in Medicine (SIIM).

Class balance #

There are 1 annotation classes in the dataset. Find the general statistics and balances for every class in the table below. Click any row to preview images that have labels of the selected class. Sort by column to find the most rare or prevalent classes.

Rows 1-1 of 1

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
pneumothorax➔ mask	2669	2669	1	1.37%

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.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.

Rows 1-1 of 1

Class	Object count	Avg area	Max area	Min area	Min height	Min height	Max height	Max height	Avg height	Avg height	Min width	Min width	Max width	Max width
pneumothorax mask	2669	1.37%	15.39%	0.01%	5px	0.49%	987px	96.39%	268px	26.17%	10px	0.98%	861px	84.08%

Spatial Heatmap #

The heatmaps below give the spatial distributions of all objects for every class. These visualizations provide insights into the most probable and rare object locations on the image. It helps analyze objects' placements in a dataset.

Objects #

Table contains all 2669 objects. Click a row to preview an image with annotations, and use search or pagination to navigate. Sort columns to find outliers in the dataset.
