3. Medical Imaging Analysis
 Image Recognition: AI algorithms
analyze medical images, such as X-rays,
CT scans, MRIs, and pathology slides, to
detect abnormalities, tumors, fractures,
and other conditions with high accuracy.
 Segmentation: AI helps in segmenting
and identifying specific structures or
regions within medical images, aiding in
treatment planning and diagnosis

preserving approaches like federated learning are
gaining attention, allowing AI models to be trained
across multiple institutions without sharing
sensitive data.
 Explainable AI (XAI): Continued emphasis on
developing AI models that provide clear
explanations of their decision-making processes,
enhancing transparency and trust.
 Integration of Multi-modal Data: AI will
increasingly integrate information from various
sources, such as imaging, genomics, and clinical
data, to provide a more comprehensive
understanding of patient health.
