Screening and Triage for TB using Computer-Aided Detection (CAD) Technology and Ultra-portable X-Ray Systems: A Practical Guide

Overview

The use of AI technology for medical diagnostics has accelerated rapidly in the past decade and AI-powered CAD software products are increasingly being used to analyze medical images, such as chest radiographs or X-rays. In March 2021, the World Health Organization (WHO) recommended for the first time that CAD software programmes may be used in place of human readers for the interpretation of digital CXR in screening and triage for TB disease in individuals aged 15 years or more. Selected ultra-portable digital X-ray systems and CAD software now available in the GDF Catalog at a lower than market pricing.

With the support from the United States Agency for International Development (USAID) and Global Affairs Canada, a practical guide on the implementation of CAD technology and ultraportable X-ray systems was developed to provide advice on how to convert WHO policy guidance into a practical implementation plan, building on initial field experience gained by early implementers.

This guide offers various technical explanations of the newly added products available in the GDF catalogue including:

The guide will be periodically updated to reflect product updates, ongoing experience, and to include any relatively straightforward techniques and tools that could be more widely adopted. For further information, please contact zhizhenq@stoptb.org.

Coming soon- translations of the practical guide and annexes into Russian. If you would like to translate the guide into another language, please contact zhizhenq@stoptb.org
