The proton treatment control system is the supporting software of the proton therapy device, which specifically coordinates and controls the status and work of each subsystem. In this study, the software architecture and hardware implementation of the proton treatment control system was developed and built a foundation for the overall debugging. Using C# programming language and WPF programming techniques, TCP network communication protocol specified by the proton treatment technical document and MVVM pattern in Windows system, the logic design and implementation of each level were studied. Meanwhile, the communication interface between the subsystems under TCP communication protocol was agreed. The logic design and research of the setup field and treatment field were carried out. And the User Interface was designed and developed using the above technology. The program realizes the communication and interaction between the proton treatment control system and each subsystem, so as to control and monitor the whole treatment process. The proton treatment control system provides a software basis for the remote overall debugging and on-line monitor and control of proton treatment device.

Brain-computer interface (BCI) can be summarized as a system that uses online brain information to realize communication between brain and computer. BCI has experienced nearly half a century of development, although it now has a high degree of awareness in the public, but the application of BCI in the actual scene is still very limited. This collection invited some BCI teams in China to report their efforts to promote BCI from laboratory to real scene. This paper summarizes the main contents of the invited papers, and looks forward to the future of BCI.

Informatization is an effective way to promote the reform and innovation of higher education and improve its quality. Virtual simulation teaching is indispensable in the educational informatization. Here, we describe the development and current situation of virtual simulation teaching, and introduce electronic standardized patient (ESP) based-virtual human body system powered by the real-time human physiological parameters. We also discuss how to build an ESP-based community in the teaching of human physiology, preclinical integrated case learning and other teaching projects. These ESP-based virtual simulation projects display the advantages of interdisciplinary fusion and the combination of basic and clinical knowledge, and open up the third type of functional experiments. Therefore, ESP-based virtual simulation teaching platform presumably becomes a considerable option for the first-class course construction in physiology.

Brain-computer interface (BCI) is a revolutionizing human-computer Interaction, which is developing towards the direction of intelligent brain-computer interaction and brain-computer intelligent integration. However, the practical application of BCI is facing great challenges. The maturity of BCI technology has not yet reached the needs of users. The traditional design method of BCI needs to be improved. It is necessary to pay attention to BCI human factors engineering, which plays an important role in narrowing the gap between research and practical application, but it has not attracted enough attention and has not been specifically discussed in depth. Aiming at BCI human factors engineering, this article expounds the design requirements (from users), design ideas, objectives and methods, as well as evaluation indexes of BCI with the human-centred-design. BCI human factors engineering is expected to make BCI system design under different use conditions more in line with human characteristics, abilities and needs, improve the user satisfaction of BCI system, enhance the user experience of BCI system, improve the intelligence of BCI, and make BCI move towards practical application.

The development and potential application of brain-computer interface (BCI) technology is closely related to the human brain, so that the ethical regulation of BCI has become an important issue attracting the consideration of society. Existing literatures have discussed the ethical norms of BCI technology from the perspectives of non-BCI developers and scientific ethics, while few discussions have been launched from the perspective of BCI developers. Therefore, there is a great need to study and discuss the ethical norms of BCI technology from the perspective of BCI developers. In this paper, we present the user-centered and non-harmful BCI technology ethics, and then discuss and look forward on them. This paper argues that human beings can cope with the ethical issues arising from BCI technology, and as BCI technology develops, its ethical norms will be improved continuously. It is expected that this paper can provide thoughts and references for the formulation of ethical norms related to BCI technology.

Virtual reality (VR) is defined as an approach to user-computer interface that involves real-time simulation of an environment, scenario, or activity that allows for user interaction via multiple sensory channels. In recent years, virtual reality has grown immensely with rapid advancement of VR technologies in the field of stroke rehabilitation. In this paper, current VR applications to the field of rehabilitation are reviewed. In the field of stroke rehabilitation, many clinical trials related to VR-based assessment and treatment have been performed to assess and treat arm dysfunction, walking ability, visuospatial problems, cognitive dysfunction, etc. Among them, VR is beneficial in improving arm function when compared with conventional therapy with limited evidence. Whether VR improves walking, visuospatial problems, or cognitive function has not been well established yet. However, VR can simulate the real environment without the risks arising from errors, and can also give a sense of immersion in the simulated environment and a concomitant feeling of 'presence'. Moreover, VR provides the motivation of gaming factors. With these advantages, VR will be one of the major advanced technologies for assessment and managing post-stroke dysfunction in the future.

Traditionally, a novice ear doctor acquires the skillfully operative ability through dissecting cadaveric temporal bone in ear surgical training lab. For conceivable reasons donated bodies are always short in supply, virtual reality-based simulator provides a new model for surgical training. It has been proven that the simulator is a useful tool for surgical training. And it can be used in the rehearsal of operation procedures, real-time operation guidance, and remote surgery. Our design is different from the existing virtual surgical system. It has a parallel, distributed multi-workstation with the vivid three-dimensional model of temporal bone, and it can be used not only to learn the ear surgical skills in the virtual environment, but also preoperative plan and surgical consultation.
