1. INTRODUCTION

The integration of artificial intelligence (AI) in healthcare is far from a recent development. Dating back to the 1970s, the initial applications of AI were employed to address biomedical challenges. Since then, AI-powered applications have undergone significant expansion and adaptation, revolutionizing the healthcare sector. This transformationhasledtocostreduction,enhancedpatient outcomes, and overall improvements in operational efficiency. Prior to delving into the progression of AI in healthcare, it's helpful to grasp the fundamentals of how

artificial intelligence operates. In essence, AI refers to computer models and programs designed to replicate human-level intelligence, engaging in cognitive functions such as intricate problem-solving and gathering experiences.

The bulk of AI tools on the market are classified as "Narrow AI," which denotes that the technology is superior to humans in certain, well-defined task areas. Machine learning techniques, which enable computers to learn, carry out tasks, and modify their performance without requiring direct human intervention, are used in many of these artificial intelligence applications. In 1955, the phrase "artificial intelligence" was first used in a proposalforaconferenceatDartmouthCollege.However, it wasn't until the early 1970s that artificial intelligence (AI) applications made their way into the healthcare industry with the creation of MYCIN, a program meant to helpwithbloodinfectiontreatmentidentification.

The momentum of AI research continued, leading to the formation of the American Association for Artificial Intelligence in 1979, which is now known as the Association for the Advancement of Artificial Intelligence (AAAI). During the 1980s and 1990s, the evolution of AI systems contributed to significant medical advancements. This included improvements such as accelerated data collection and processing, assistance in more precise surgical procedures, extensive research and mapping in the field of database administration (DBA), and the widespread implementation of electronic health records formorecomprehensivehealthcaremanagement.

Machine learning represents a distinct subset of artificial intelligence,enablingsystemstolearnanddiscernpatterns from data with minimal human intervention. Rather than being explicitly instructed on what actions to take, computersemployingmachinelearningarepresentedwith patternsand data. Subsequently, they autonomously draw conclusions and enhance their performance based on the information provided. This approach contrasts with traditional programming where computers are explicitly programmedwithspecificinstructions.
