Literature Survey The integration of Artificial Intelligence (AI) and Cloud Computing in healthcare has gained significant attention due to its potential to improve disease diagnosis, predictive analytics, and patient care. Various research studies have explored the application of AI-driven models in medical imaging and healthcare analytics, while cloud-based frameworks have been adopted for scalable and real- time processing of medical data[9]. This section reviews existing studies in AI-driven medical imaging, cloud-based healthcare systems, and AI- powered predictive analytics.AI has been extensively used for medical imaging analysis, allowing for the early detection of diseases such as cancer, brain tumors, cardiovascular diseases, and lung abnormalities[10]. In this research the efficiency of AI-driven image analysis techniques in enhancing diagnostic accuracy and reducing human error. These studies show that AI-based models are capable of identifying subtle patterns in medical images that may not be easily detected by human experts[11]. Cloud computing has emerged as a key enabler for scalable and remote healthcare solutions, allowing for the efficient storage, processing, and analysis of large-scale medical data[12].In this research demonstrates how cloud-based platforms facilitate real-time medical image analysis and remote diagnosis, especially in regions with limited healthcare infrastructure[13]. Cloud-based solutions also enable collaborative healthcare, where multiple medical institutions can access and analyze patient data securely[14]. However, latency issues, data privacy concerns, and integration challenges still pose limitations to cloud adoption in healthcare.AI- driven predictive analytics has been widely used to forecast disease progression, identify at-risk patients, and optimize treatment plans[15]. The studies have explored AI-based models that analyze electronic health records (EHRs), medical histories, and patient biomarkers to predict the likelihood of diseases before symptoms become severe[16]. These predictive models have been successful in improving early disease detection and personalized medicine. However, the effectiveness of such models depends on the quality of training data, model interpretability, and computational efficiency[17]. Over the years, various techniques have been employed in healthcare analytics for disease diagnosis and predictive analysis. Traditional machine learning methods, such as Support Vector Machines (SVM), Decision Trees, and Random Forests, have been widely used for medical data classification[18]. While these models provide decent accuracy, they often require manual feature extraction, making them less efficient in handling large-scale and complex medical data, such as MRI and CT scans[19]. Additionally, their performance is highly dependent on data quality and feature selection, leading to potential inconsistencies across different datasets[20]. 3. Problem statement Although AI and cloud computing have shown great promise in healthcare applications, several challenges remain: • Computational Efficiency: AI-based medical models require high-performance computing resources, making them difficult to deploy in real-time clinical settings[14]. • Data Security & Privacy: Cloud-based storage of medical data raises concerns about cybersecurity threats, unauthorized access, and compliance with healthcare regulations (e.g., HIPAA, GDPR) [16]. CTMJ | traditionalmedicinejournals.com Chinese Traditional Medicine Journal | 2018 | Vol 1 |Issue 5 14 • Scalability & Integration: Many AI models are trained on specific datasets, limiting their generalization and scalability across diverse populations and medical conditions[19]. 4.
