Pneumonia Checker

What is pneumonia?

Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.

We have used more than 6000 X-Ray images to teach our machine to detect pneumonia.
Chest X-ray images (anterior-posterior) were selected from retrospective cohorts of pediatric patients of one to five years old from Guangzhou Women and Children’s Medical Center, Guangzhou. All chest X-ray imaging was performed as part of patients’ routine clinical care.

For the analysis of chest x-ray images, all chest radiographs were initially screened for quality control by removing all low quality or unreadable scans. The diagnoses for the images were then graded by two expert physicians before being cleared for training the AI system. In order to account for any grading errors, the evaluation set was also checked by a third expert.


The app addresses such common questions as:

* What is pneumonia
* what are the symptoms of pneumonia
* scan your X-RAY and gives you the result if you have pneumonia
* the app doesn’t need internet connection


This app is written and intended for practicing clinicians like family physicians, internists, pediatricians, ER docs, and hospitalists; for resident physician trainees; and for medical students. As an educator and clinician, I am interested in feedback and I would be grateful for guidance on improving the too.

Advice: Please don't rely on this app 100% in all cases you need to visit a doctor to determine your condition.
