Title
(EN) SYSTEMS, DEVICES AND METHODS FOR NON-INVASIVE HEMATOLOGICAL MEASUREMENTS
(ZH) 用于非侵入性血液测量的系统、装置和方法
Abstract
(EN) A system for non-invasive hematological measurements includes a platform to receive a body portion of a user and an imaging device to acquire a set of images of a capillary bed in the body portion. For each image, a controller detects one or more capillaries in the body portion of the finger to identify a first set of capillaries by estimating one or more attributes of each capillary (e.g., structural attributes, flow attributes, imaging attributes, or combinations thereof), wherein at least one attribute of each capillary meets a predetermined criterion. The controller also identifies a second set of capillaries from the first set of capillaries such that each capillary of the second set of capillaries is visible in a predetermined number of images of the set of images.
(ZH) 一种用于非侵入性血液测量的系统包含:平台,其用以接收用户的身体部分;和成像装置,其用以获取所述身体部分中的毛细血管床的一组图像。对于每个图像,控制器检测手指的所述身体部分中的一个或多个毛细血管,以通过估计每个毛细血管的一个或多个属性(例如,结构属性、流量属性、成像属性,或其组合)来识别第一组毛细血管,其中每个毛细血管的至少一个属性符合预定准则。所述控制器还识别来自所述第一组毛细管的第二组毛细管,使得所述第二组毛细管中的每个毛细管在所述一组图像中的预定数目个图像中可见。
