Introduction to Artificial Intelligence
Artificial Intelligence is a branch of computer science focused on developing systems that can perform tasks that typically require human intelligence. These tasks can include reasoning, learning from previous information, recognizing patterns, and making decisions.
AI systems can process large volumes of data and generate useful insights. This capability makes Artificial Intelligence valuable in many fields, including healthcare, where large amounts of medical and patient data are generated every day.
AI in Healthcare
Artificial Intelligence in healthcare involves using intelligent algorithms and technologies to analyze medical information, support treatment decisions, predict potential health risks, and improve patient care.
AI systems can process historical information stored in Electronic Health Records (EHRs) and use it to identify patterns that may support disease prevention, diagnosis, and treatment. Healthcare institutions such as Memorial Sloan Kettering Cancer Center and Mayo Clinic have explored AI applications to support healthcare operations and research.
Technology companies, including IBM and Google, have also developed AI-based healthcare technologies aimed at improving healthcare delivery and supporting operational efficiency.
