Brief Summary

The Chang Gung Pneumothorax Detection Software is a medical software that can automatically detect whether there is a pneumothorax in Chest X-Ray. The purpose of this study is to verify whether the Chang Gung Pneumothorax Detection Software can correctly identify patients with pneumothorax in Chest X-Ray. The results of the software analysis will be used for the performance of the software on the primary and secondary outcomes.

Interventions

Chang Gung Pneumothorax Detection SoftwareDEVICE

The Chang Gung Pneumothorax Detection Software is an independent software as a medical device, which inputs digital Chest X-Ray to automatically detect whether there is a pneumothorax. The inferred results output by this software can assist clinicians or professional medical personnel to identify whether a patient has pneumothorax. This product is only used to analyze the digitized Chest X-Ray DICOM of patients over 20 years old and under 100 years old.

Sampling MethodProbability Sample
Study Population

This is a retrospective study, and the data comes from the Chang Gung Medical Research Database(CGRD) which was an database form 6 hospitals of Chang Gung Memorial hospital. According to inclusion and exclusion criteria, Chest X-ray data from the database during 2006.01.01\~2020.12.31 was collected.

You may qualify if:

  • The case were over 20 years old and under 100 years old.
  • DICOM format.
  • Brand model of Canon.
  • DICOM resolution length range (700-3400 pixels), width range (490-3600 pixels).
  • poster-anterior view(PA-view) of chest X-ray

You may not qualify if:

  • The chest X-ray contains items that affect interpretation, such as chest tubes, endotracheal tubes, and heart rhythm regulators, but does not include patches and circuits used in electrocardiograms.
  • The chest X-ray that are difficult to interpret due to poor image quality.
