基于V4L2的超声波鼻炎治疗仪可视化研究

Research on Visualization of Ultrasonic Rhinitis Therapeutic Apparatus Based on V4L2

本文研究并开发了一种带有鼻内镜功能的新型超声波鼻炎治疗仪可视化系统。在Linux平台下,用视频采集卡采集鼻内镜视频数据,借助操作系统提供的视频应用程序接口Video4Linux2(V4L2)获取视频采集卡数据,并利用Qt实时显示视频图像,实现了新型超声波鼻炎治疗仪的可视化功能,解决了当前超声波鼻炎治疗仪依赖庞大且昂贵的鼻内窥镜成像设备的问题,简化了医生的操作,满足了治疗时监控鼻腔的需求,大大降低了治疗成本,有利于该仪器的推广。经过测试,鼻内镜图像清晰流畅,完全满足超声波治疗鼻炎的临床需求。

This paper reports the study and design of a visualization system of the ultrasonic rhinitis therapeutic apparatus with the function of endoscopic sinus.On Linux operating platform,we captured the video data of a video capture card that connected the endoscopic sinus using Video4Linux（V4L2）that was provided by the operating system.The video images were displayed by Qt.The visualization system solved the problem that the current ultrasonic rhinitis therapeutic apparatus had to rely on the large and expensive endoscopy equipment.And this simplified the doctors＇ operation,met the need of monitoring nasal cavity in the process of operating,greatly reduced the costs of treatment and would contribute to the promotion of the instrument.As a result,it has been tested that the nasal endoscopic image achieved by the system is clear and smooth,and fully meet the clinical needs of ultrasonic treatment of rhinitis.
