CAD4TB: How does it work?

The CAD4TB system
  • Quickly analyses posterior-anterior chest X-ray images.
  • Processes images from different X-ray manufacturers.
  • Utilises state-of-the-art deep learning models to provide the output results.
  • Trained in a large dataset of images from various sites and countries.
  • Developed and trained based on bacteriological reference.

Designed to provide simple and focused output to streamline the TB screening process, CAD4TB delivers the following results:

  • Tuberculosis probability score based on a bacteriological reference ranging from 0 to 100.
  • Abnormality score that denotes lung abnormalities, based on a radiological reference ranging from 0 to 100.
  • Generates a heatmap indicating potential tuberculosis abnormalities as a coloured overlay on the original chest X-ray image.
  • The cardiothoracic ratio helps evaluate the size of the heart, potentially indicating cardiomegaly (an enlarged heart).

CAD4TB can also be supported by CAD4Silicosis for the rapid detection of silicosis-related abnormalities.

Understanding CAD4TB: offline & online deployments

CAD4TB is available offline (CAD4TBbox) and online (CAD4TBcloud) solutions.

CAD4TBbox (offline solution):
  • Optimal for locations with no or unreliable internet connection.
  • Enables on-site processing of chest radiography images.
  • Images will be stored locally ensuring that they stay within the country.
  • Six-hour battery life.
  • Data (patient information and images) can be uploaded to the CAD4TBcloud when internet is available.
  • PACS integration.
CAD4TBcloud (online solution):
  • Accessible with a reliable internet connections.
  • Integrated into a web-based Platform.
  • Users worldwide can upload chest radiography images to the CAD4TB Platform.
  • Facilitates rapid tuberculosis screening by analysing the image in only 5 seconds.

The CAD4TB Platform: enable AI & digitalise TB screening data management

To support the END-TB strategy by finding the missing cases, we have developed additional screening analytics and management tools to enable users to rapidly screen risk groups, support prevalence surveys, and collect all information into on Platform.

CAD4TB Platform includes:
  • Artificial intelligence (AI) modules
  • Patient registration
  • Symptoms registration (through customizable forms)
  • Patient reporting

It digitalises screening results, eliminated the need for paper records, and is compatible with any X-ray system that outputs a DICOM image.

Connectivity and integration options are available via API, offering an easy interface for TB screening.

Platform features include:
  • Multi-lingual support
  • Higher privileges for administrator users
  • Other features
Dynamic Threshold feature:
  • Analyses previous CAD4TB results while considering bacteriological testing capacity.
  • Automatically suggests an optimised threshold for a given screening project.
  • Calculation is done instantly and can be used onsite without an internet connection.

The ‘insights’ module provides valuable insights to management on the program, showing data distribution in terms of gender, age, and CAD4TB scores of those screened.

All data from individual sites can be synchronised to a central cloud.

CAD4TB Platform is available in multiple languages (Arabic, Bahasa Indonesia, Bengali, English, French, Portuguese, Russian, Spanish, Tagalog, Thai, Urdu and Vietnamese). More languages are available upon request.

Bi-directional Tuberculosis/COVID-19 Screening

The COVID-19 pandemic is threatening the global goals to fight to end TB by 2030. Thereupon, the importance to implement prioritized mitigation measures and innovations for TB programs have been indicated from across the globe. This includes prioritizing bi-directional screening/testing for TB and COVID-19, using X-ray with CAD (computer-aided detection).

At the start of the pandemic, we developed CAD4COVID which uses the same technical core and quality standard as our proven CAD4TB software. With years of digital X-ray and CAD field implementation expertise, our response to the bi-directional screening equation pertaining to TB and COVID-19 is apparent.

Procuring CAD4TB via GDF Diagnostics Catalogue

The Stop TB Partnership’s Global Drug Facility (GDF) announced the inclusion of ultra-portable digital X-ray systems and software packages for the computer-aided detection (CAD) of tuberculosis (TB) based on AI. These TB combat tools will be made available at a reduced cost to all TB programs around the globe. We are proud to announce that CAD4TB can now be easily procured through the Diagnostics Catalogue of GDF at a pre-negotiated price.
