Computer-Aided Detection for Tuberculosis

CAD4TB is a CE-certified AI software to support fast, easy, highly accurate automated TB detection with cost-efficiency. CAD4TB is available for online and offline use, enabling data-driven TB screening in resource constrained settings. It can analyse images of individuals aged four and above.

Features of CAD4TB

  • CAD4TB outputs:

– An abnormality score (between 0 and 100)
– A heat map indicating possible areas of abnormalities associated with TB

  • Results are ready within 2 seconds
  • Images of adults and children from age 4+ can be processed
  • Available for online (CAD4TBcloud) and offline (CAD4TBbox)
  • Integrated & data-driven TB screening by CAD4TB platform
  • The latest version includes cardiomegaly analysis

Artificial Intelligence for TB detection

CAD4TB is a Class IIb medical software which quickly analyses a digital chest X-ray image and gives an indication if the subject on the image has abnormalities that may be related to pulmonary TB. The software has been trained in the detection of TB-related abnormalities by applying deep learning. CAD4TB has also received expert feedback from lung specialists, making it extremely accurate and reliable.

Advantages of CAD4TB

CAD4TB can facilitate fast, easy, highly accurate automated TB detection with cost efficiency: it does not require skilled human readers to determine if the subject is a presumptive TB case; and only if the output score is higher than a certain threshold, patient will need confirmatory testing to finalize the diagnosis.

Various scientific publications suggest that CAD4TB can perform on par or significantly better than human expert readers and meets the WHO’s Target Product Profile. ‘Studies also highlight that CAD4TB can increase daily screening throughput by 2.5 times, reduce the cost per screen by 50%, and save Xpert test usage with up to 75% and save Xpert test usage with up to 75%.

The offline CAD4TB solution is relevant for the use in resource-constrained settings with high daily throughput.

Data agility with CAD4TB Platform

Evolving from paper-based to digitalised data management using one platform is key to further making the TB screening process efficient. Therefore, we introduce the CAD4TB Platform with SAM (Screening-Analytics-Management) functionalities as an add-on to the CAD4TB AI software.

 Features of CAD4TB Platform

The CAD4TB platform provides modules for patient registration, symptoms registration, and reporting including individual report and dashboards. It digitizes the TB screening process and provides valuable and targeted insights, including gender, age demographics and CAD4TB scores.

Data governance for successful adoption of digital TB screening

The CAD4TB platform enables TB programs to rapidly screen risk groups and support prevalence surveys while simultaneously collecting digitized data and information into one platform. Thus, it facilitates and simplifies data governance and optimizes the successful adoption of digital TB screening systems. The SAM  functionalities contribute to data quality and integrity while avoiding data fragmentation. It also enables data access from multiple locations: by providing connectivity with other data systems at the national level, SAM can serve as the first data entry point for health workers at the community level, thereby ensuring that National TB Programs can access aggregated data and dashboards.

Within 2 seconds, the CAD4TB software analyses a chest X-ray, detects abnormalities and indicates the likelihood that active TB is present. This allows costly TB tests to be used only in suspected cases.

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.

CAD4TB in Practice

Real-World Applications in TB Programmes for Impact

This whitepaper aims to support the Ministries of Health, National Tuberculosis Programs, NGOs and private health providers in selecting, incorporating, and implementing AI-enabled Computer-Aided Detection (CAD) for TB screening and triaging, particularly in resource constrained settings. It outlines the technical aspects and deployment of CAD4TB, a World Health Organization (WHO)-evaluated CAD software. The document seeks to facilitate the optimal use of CAD4TB by considering clinical needs, local infrastructure, operational environments, human resources, budgets, and total cost of ownership.
