The book “AI-Driven Healthcare Systems: From Diagnosis to Decision Support” has been written with the aim of exploring one of the most transformative intersections of modern science—artificial intelligence (AI) and healthcare. The rapid progress in computational intelligence, data analytics, and machine learning has redefined how healthcare professionals approach diagnosis, treatment planning, and decision-making. This book brings together these emerging trends to present a unified perspective on AI’s potential to revolutionize healthcare delivery across clinical and research environments.

Healthcare systems have traditionally relied on human expertise supported by technological tools. However, the increasing availability of medical data, advancements in imaging technologies, and breakthroughs in deep learning have paved the way for systems that not only assist but also enhance medical intelligence. The chapters in this book discuss how AI models—spanning machine learning, deep neural networks, natural language processing, and computer vision—are applied to medical imaging, predictive analytics, electronic health records (EHRs), drug discovery, and personalized medicine.

The intent of this work is to provide both conceptual clarity and applied insights for students, researchers, healthcare practitioners, and policymakers who are keen to understand the evolving AI ecosystem in medicine. Each chapter is structured to balance theoretical foundations with practical case studies, thereby bridging the gap between technical innovation and clinical applicability. The book also emphasizes ethical, legal, and societal implications to encourage responsible adoption of AI in healthcare systems.

I sincerely hope that this book will serve as a valuable resource for learners at all levels and inspire further innovation in developing intelligent, reliable, and patient-centric healthcare solutions. The responsibility for ensuring the safe, transparent, and equitable use of AI in medicine lies in our collective hands, and this book is a modest contribution toward that vision.
