静脉成像投影设备的研制
|
摘要
目的:研制静脉成像投影设备,并进行临床应用验证。方法:以现有市售元器件作为购买配置依据,利用发射光静脉成像原理,搭建以工控机作为中央控制单元,外围由微型投影、摄像头等构成的电路,工控机传输、储存由摄像头采集到的图像,经相应图像处理算法后传输到微型投影设备,实现静脉血管纹路的投影显示。结果:成像后的静脉血管投影纹路与实际血管走向基本吻合,图像质量良好。结论:研制的静脉成像投影设备能够满足临床应用需要,可为后续研究提供科学依据。
Objective: To introduce a method and theory about how implementation vein image projection epidermis and conduct the clinical testing. Methods: Base on existing electronic components construct circuit. The construct circuit was made of industrial personal computer, mini-projector, camera and so on. The image is captured by camera transfer to industrial personal computer. Choosing suitable image process algorithms modify image. Processed image that storage in industrial personal computer transfer to mini-projector, vascular vein lines is produced from mini-projector. Results: Through this way that vascular vein projector method get image basic agreement vascular trend, meet the clinical needs. Conclusion: Vein image projection methods meet clinical need can be used to study other field.
