A Systematic Literature Review of Digital Twin Research for Healthcare Systems: Research Trends, Gaps, and Realization Challenges

IEEE Access, Год журнала: 2024, Номер 12, С. 4099 - 4126

Опубликована: Янв. 1, 2024

Using the PRISMA approach, we present first systematic literature review of digital twin (DT) research in healthcare systems (HSs). This endeavor stems from pressing need for a thorough analysis this emerging yet fragmented area, with goal consolidating knowledge to catalyze its growth. Our findings are structured around three questions aimed at identifying: (i) current trends, (ii) gaps, and (iii) realization challenges. Current trends indicate global interest interdisciplinary collaborations address complex HS However, existing predominantly focuses on conceptualization; integration, verification, implementation is nascent. Additionally, document that substantial body papers mislabel their work, often disregarding modeling twinning methods necessary elements DT. Furthermore, provide non-exhaustive classification based two axes: the object (i.e., product or process) context patient's body, medical procedures, facilities, public health). While testament diversity field, it implies specific pattern could be reimagined. We also identify gaps: considering human-in-the-loop nature HSs focus provider decision-making research. Lastly, discuss challenges broad-scale DTs HSs: improving virtual-to-physical connectivity data-related issues. In conclusion, study suggests DT potentially help alleviate acute shortcomings manifested inability concurrently improve quality care, wellbeing, cost efficiency.

Abstract Visualization plays a crucial role in molecular and structural biology. It has been successfully applied to variety of tasks, including analysis interactive drug design. While some the challenges this area can be overcome with more advanced visualization interaction techniques, others are challenging primarily due limitations hardware devices used interact visualized content. Consequently, researchers increasingly trying take advantage new technologies facilitate work domain scientists. Some typical problems associated classic 2D interfaces, such as regular desktop computers, lack natural spatial understanding interaction, limited field view. These could solved by immersive virtual environments corresponding hardware, reality head‐mounted displays. Thus, investigating potential visualization. There is already body ranging from educational approaches protein applications for collaborative This review focuses on whole, aiming cover comprehensively. We divide existing papers into different groups based their application areas, types tasks performed.

The advent of 6G networks and beyond calls for innovative paradigms to address the stringent demands emerging applications, such as extended reality autonomous vehicles, well technological frameworks like digital twin networks. Traditional cloud computing edge architectures fall short in providing their required flexibility, scalability, ultra-low latency. Cloud centralizes resources distant data centers, leading high latency increased network congestion, while computing, though closer sources, lacks agility dynamically adapt fluctuating workloads, user mobility, real-time requirements. In-network (INC) offers a transformative solution by integrating computational capabilities directly into fabric, enabling dynamic distributed task execution. This paper explores INC through lens information-centric networking (ICN), revolutionary communication paradigm implementing routing-by-name in-network caching, thus natural enabler INC. We review state-of-the-art advancements involving ICN, addressing critical topics service naming, executor selection strategies, compute reuse, security.
