DxTB highlights regions of a chest X-ray that have specific abnormalities associated with tuberculosis (TB) and helps radiologists to prioritize and reduce their workload. DxTB is an adaptive system that evolves over time based on every new X-ray read in the field. DxTB also automatically generates Radiological Society of North America (RSNA) standard radiology reports.
Certification
CE and FDA mark pending (expected Q2 2021)
Development Stage
On the market
Deployment
Online & offline (with intermittent internet connection) with local edge computing device.
Intended Age Group
14+ years
Target Setting
Primary health centers, general hospital (above primary level), teleradiology companies, government/public sector, e.g. national TB program, and private sector. An automated solution or a teleradiology-backed AI diagnosis and report is provided depending on the situation.
