Introduction
In the era of digital transformation, artificial intelligence (AI) has emerged as a transformative technology reshaping various industries [1]. Particularly in healthcare, AI applications have shown tremendous potential in improving diagnostic accuracy and treatment efficiency [2]. However, the integration of AI systems in clinical practice faces significant challenges, including data privacy concerns and algorithmic transparency [3].
While previous research has focused on developing sophisticated AI models, there remains a critical gap in understanding the ethical implications and regulatory frameworks necessary for responsible AI deployment [4]. This study aims to address this gap by examining the current state of AI governance in healthcare and proposing a comprehensive framework for ethical AI implementation.
The remainder of this paper is organized as follows: Section 2 reviews the existing literature on AI in healthcare; Section 3 presents our research methodology; Section 4 discusses the findings; and Section 5 concludes with recommendations for future research.
