JF CXR-2 is a screening and triaging tool to help clinicians identify abnormalities on chest X-rays. JF CXR-2 can also be used as a prioritization tool for radiologists and teleradiology companies.
Certification
Pending, China NMPA tier-3 approval
Development Stage
On the Market
Deployment
Online & Offline
Intended Age Group
15+ years
Target Setting
Primary health centres, teleradiology companies, government/public sector, e.g. national tuberculosis (TB) programme, private sector
Current Market
China
Input
Can be used to read images from any kind of chest X-ray machine (vendor neutral)
Chest X-ray image format: DICOM
Chest X-ray type: posterior-anterior chest X-ray
Other requirements: none
Output
Output in the form of:
Heat map
Probability score for TB and dichotomized outcome for TB
Probability score for any abnormality, pneumonia, nodule
Pop-up alert message when TB score exceeds cut-off and a line list of all examination records which allows sorting, searching, exporting and statistical analysis
Hardware
Online: basic desktop without GPU to upload the DICOM files to the server. Recommended specs: Intel Xeon E5-2650, 8 GB memory, 500 GB disk space
Offline: Intel Xeon E5-2650, 16 GB memory, 1 TB disk space
Server
A proprietary software that supports FTP/SFTP-style DICOM uploading.
Offline: none
Hardware

Integration with X-ray Systems
Integration with PACS and Legacy Systems
It is possible to integrate the product with client’s legacy picture archiving and communication (PACS) system.
Software
A proprietary software that supports File Transfer Protocol (FTP)-style DICOM uploading
Processing Time
Online deployment: it takes around 1 second for the artificial intelligence (AI) algorithm to process the image and generate the result, but the time to upload the DICOM file may vary depending on the local internet environment.
Offline deployment: it takes around 5 seconds for the AI algorithm to process the image and generate the result.
Data Sharing & Privacy
Server location: the server is currently located on AliCloud in China. It can be deployed locally and offline
Upon consent, the pixel array from the DICOM file is shared when the DICOM is generated and uploaded to the company's cloud platform
The shared data are used for troubleshooting, monitoring product usage, training or improvement of software. The AI results are confirmed by JF Healthcare's team of radiologists. Customers are also notified of any emergent abnormalities e.g. pneumothorax/pneumoperitoneum not related to TB
There is an option to de-identify data
Price
Volume-based pricing models are available

For improving existing functions, the updates usually do not include additional fees. If new functions are added, the customer can choose whether to pay for additional functions or not. Currently, there are no cost differences between the private and public sector
Extra costs: none for minor updates
Product Development Method
Supervised deep learning (CNN, RNN)
Training
The product was trained on over 120 000 chest X-rays from China
Reference Standard
Human reader
