In recent years, technology integration in healthcare has revolutionized patient care, leading to the emergence of smart healthcare systems. Different areas of artificial intelligence (AI) like image processing, natural language processing, and signal processing have found their way into the healthcare domain, making it smarter. Systems have been developed for analyzing medical images like X-rays and CT scans for anomaly detection. Speech-based systems have also been an area of interest for medical applications like depression recognition. Researchers have presented various systems for processing medical signals like ECG and EEG. The development of large language models has also quicken up the developments in this field. Medical chatbots have now become much sharp and intelligent and can cater to a larger number of patients more effectively. This chapter presents such advances in AI domain that have contributed to the field of computer-aided healthcare and the possibility of full-fledged multifaceted systems.
