Detailed introduction

(激光多普勒血流仪 有多种型号 ,适合对多种组织器官进行点式或线式的快速扫描 ,我们会针对您的实验推荐合适的型号和配置, 敬请来电咨询) Laser Doppler Scanning Imaging System (Laser Doppler flowmeter has multiple models , suitable for point or line fast scanning of a variety of tissues and organs , we will recommend the appropriate model and configuration for your experiment, respect Please inquire)

 

Performance of Laser Doppler Scanning Imaging System:

非接触:图像由低功率激光扫描组织获得。 Ø Non-contact: The image is obtained by scanning the tissue with a low-power laser. The maximum distance between the patient and the scanner is 1m ;

日间操作:独特的光学设计,即使在室内环境光线很强时也能操作 Ø Daytime operation: unique optical design, even when the indoor ambient light is strong ;

重复扫描模式:可对进行性反应成像,并通过自动分析功能定量 Ø Repeat scanning mode: it can image progressive reactions and quantify by automatic analysis function ;

彩色数码相机简化扫描设置,并提供扫描区域的照片 Ø Color digital camera simplifies scanning settings and provides photos of the scanned area ;

高分辨率 高达256x256个独立检测:分辨率为0.2~2.0mm/像素。 Ø High resolution up to 256x256 independent detection: resolution of 0.2 ~ 2.0mm / pixel. High resolution models with 0.1mm / pixel are also available ;

灵活的扫描尺寸,从1像素到50cm x 50cm的任意矩形 Ø Flexible scanning size, any rectangle from 1 pixel to 50cm x 50cm ;

界面友好的软件,数据库记录并存储了患者资料和图像信息非常容易进入和进行搜索 Ø User-friendly software, the database records and stores patient information and image information. It is easy to enter and search ;

双波长/高分辨率版本可供选择 ØDual -wavelength / high-resolution version is available ;
