Seminar Title: 

Replacing the Pap Smear with Visualization and Artificial Intelligence at the Point of Care



Cervical cancer screening and management around the world is about to be disrupted by a new visual diagnostic test - automated visual evaluation (AVE) - where images of the cervix are analyzed by a machine learning classifier.  AVE holds considerable promise over existing tests - it is highly accurate and inexpensive lab-free test that returns a result at the point of care.  AVE can run on mobile imaging devices, such as the Enhanced Visual Assessment (EVA) System, a cloud-connected mobile colposcope with computing power and an internet connection.

This seminar reviews the development of the EVA System, and how it has become a platform for running AVE in low resource settings.  Results from deployments of the EVA system in many low and middle income countries are shown.  EVA images from around the world - and their associated metadata - were aggregated for several years, and now serve as the world’s largest repository of cervical images.  Images and annotations from this database were used to train AVE classifiers.  An overview of AVE performance against histopathology is given, demonstrating how AVE compares to cytology and molecular diagnostics in different clinical management scenarios.  The practical engineering steps needed to deploy AVE technology on a global level to providers with varying clinical experience are presented.  Finally, the potential implications on public health programs are discussed, along with challenges that will accompany scaling.
