基于虚拟现实的生物反馈治疗系统的研究与实现
发布时间：2018-12-27 15:09
【摘要】：生物反馈技术是目前在医学界兴起的一种预防和治疗高血压等疾病的医学方法。其主要方法为：将患者的生理特征通过可视化的方式呈现出来，并反馈给患者本身。患者面对由自己生理特征控制的可视化场景，通过自我调节的方式影响场景，使场景趋向于目标状态，最终达到控制自身体征，治疗病患的效果。 本论文基于中山大学重大项目培育和新兴、交叉学科资助计划项目—“网域空间3D虚拟化关键技术在生物反馈干预高血压前期中的应用”。主要工作是：将虚拟现实技术运用于生物反馈治疗中，使患者面对近乎真实的反馈场景，达到更好的治疗效果。本论文将阐述如何完成虚拟三维场景的构建及系统原型的搭建。要求是：三维场景是可数据驱动的—即可以随着外部输入数据的不断的变化而不断变化。故在本论文中，构建的三维场景主要场景是水波，水波的高度会随着受试者体征的变化而不断变化（如，当患者的血压升高，水波的波动将会加剧；当患者的血压降低，水波的波动即趋于平稳）；而系统原型主要指的是完成对患者用的治疗系统以及医师用的控制系统的原型构建，在患者和三维虚拟场景进行交互的过程中，医师能够通过网络对系统实施参数设置并即时查看体征变化数据。 本论文属于软件工程领域和医学领域的交叉学科应用型论文，目的主要是利用计算机技术来辅助医学探究。意义是，通过构造系统雏形，为该类型应用研究奠定了一定的基础，以便于今后更加深入的探索。
[Abstract]:Biofeedback technology is a medical method to prevent and treat hypertension and other diseases. The main methods are to visualize the physiological characteristics of the patients and feed them back to the patients themselves. In the face of the visual scene controlled by their own physiological characteristics, the patient can influence the scene by self-adjustment, so that the scene tends to the target state, and finally achieves the effect of controlling his own physical signs and treating the patient. This thesis is based on the key technology of 3D virtualization in cyberspace and its application in biofeedback intervention of hypertension. The main work is to apply virtual reality technology to biofeedback therapy to make patients face real feedback scene and achieve better therapeutic effect. This paper will explain how to complete the construction of virtual three-dimensional scene and system prototype. The requirement is that three-dimensional scenes are data-driven-that is, they can change with the constant change of external input data. Therefore, in this paper, the main scene of the 3D scene is water wave, the height of water wave will change with the change of subjects' physical signs (for example, when the patient's blood pressure rises, the fluctuation of water wave will be intensified; When the patient's blood pressure is lowered, the fluctuation of water wave tends to be stable. The prototype of the system mainly refers to the prototype construction of the treatment system for patients and the control system for physicians, and in the process of interaction between patients and 3D virtual scenes, Physicians can set the parameters of the system through the network and view the physical change data in real time. The purpose of this paper is to use computer technology to assist medical inquiry. The significance is that, by constructing the embryonic form of the system, it lays a certain foundation for the study of this type of application, so as to facilitate further exploration in the future.
