CheXpert: Radiology Image Classification via Machine Learning
Stanford researchers have developed CheXpert which can reduce noise and identify several pathologies on x-rays with very high accuracy via machine learning. CheXpert can read photos of x-rays from a mobile phone and is robust to noise. The trained neural network is computationally light enough to run on mobile platforms such as cell phones or low-power computers. This can enable users anywhere, even in remote regions or without access to significant computing resources, to utilize the neural network for the radiology image classification. The dataset is open source and can be a standard benchmark to evaluate performance of chest radiograph interpretation models.
Stage of Development
Applications
- Radiologist assistance on chest x-rays
- Can be used as an app on a mobile phone
Advantages
- High accuracy- better than individual radiologists
- Automated radiology image classification
- Trained neural networks are robust to noise
- Reduced noise improves accuracy of machine learning systems
- Computationally light – can be used on mobile phones and can be deployed anywhere in the world
- Flexible – used neural network for training data but other machine learning methods can be used
- Novel – currently no automated method to reduce noise on mobile x-ray images
