Description

In recent years the healthcare industry has adopted AI methodologies. Radiology, in particular, has seen successful applications in image classification and segmentation with supervised ML approaches. The potential of automatic neural network processing of images, for example, automated screening for pathological image markers has far-reaching implications for diagnostic radiology. However, feature variation in medical images and the large number of labeled images required for successful neural network training present challenges for supervised learning.

Stephan Erberich, Kalvin Ogbuefi, and Long Ho share a semisupervised learning approach to address automated image classification toward labeling all radiological images that the department acquired. The approach is composed of cascading self-organizing maps (SOM) and convolutional neural networks (CNNs) to categorize radiological images based on image content. This provides an opportunity to create an automated AI-based system for labeling any radiographic data and queuing the categorized images downstream to specialized ML algorithms for pathology-model inference. You’ll discover the approach, methodologies, algorithm orchestration, and performance.
