nowadays, one of the main problems encountered in minimally invasive surgery and telesurgery is the detection of arteries in tissue. in this study, for the first time, tactile detection of an artery in tissue and distinguishing it from the tumor has been modeled by finite element method. in this modeling, three 2d models of tissue have been created: tissue, tissue including a tumor, and tissue ...

6G is a promising communication technology that will dominate the entire health market from 2030 onward. It not only sector but also diverse sectors. expected revolutionize many sectors including healthcare. Healthcare be fully AI-driven and dependent on technology, which change our perception of lifestyle. Currently, time space are key barriers to care able overcome these barriers. Also, prove...

The next-generation wireless networks are expected to support a number of computation-intensive and delay-sensitive applications such as virtual reality (VR), autonomous driving, telesurgery unmanned aerial vehicles (UAVs). Since many devices computation power limited, mobile edge computing (MEC) has been deemed promising way enhance service. In this paper, we propose novel cooperative MEC that...

Long distance teleoperation formulates a current control problem task yet to be solved, primarily due to the difficulty to compensate for signal latency. Predictive and modelbased control can only give satisfying results if proper description of the system’s behavior is provided. The interdisciplinary field of telesurgery has become a focal point of technologyextended medicine, where master–sla...

The Web3D Web is an emerging distributed digital media platform designed specifically for threedimensional (3D) content and other forms of rich, interactive media. Built using traditional Internet and World Wide Web technologies, the Web3D Web enables innovative 3D applications such as interactive movies; stereoscopic cinema; immersive multiplayer games; distributed virtual reality; synthetic e...

In recent years, teleoperation has shown great potentials in different fields such as spatial, mining, under-water, etc. When teleoperation is required to be bilateral, the time delay induced by a potentially large physical distance prevents a good performance of the controller, especially in case of contact. When bilateral teleoperation is introduced to the field of medicine, a new challenge a...

In this paper, teleoperation controller design for haptic exploration and telemanipulation of soft environments is studied. First, a new measure for fidelity in teleoperation is introduced which quantifies the teleoperation system’s ability to transmit changes in the compliance of the environment. This sensitivity function is appropriate for the application of telesurgery, where the ability to ...

New technologies in multimedia and communication fields have introduced new ways to transfer and save the medical image data through open networks, which has introduced new risks of inappropriate use of medical information. Medical images are highly sensitive hence secured transmission and reception of data is needed with minimal distortion. Medical image security plays an important role in the...

Hand-held robotic instruments with dextrous end-effectors offer increased accessibility and gesture precision in minimally invasive laparoscopic surgery. They combine advantages of both intuitive but large, complex, and expensive telesurgery systems, and much cheaper but less user-friendly steerable mechanical instruments. However, the ergonomics of such instruments still needs to be improved i...
