The ability to detect and evaluate ingestion is especially important in toddlers. The development of new methods for detecting and accurately measuring ingestion is therefore extremely important. One of the methods allowing such measurements is speckle pattern analyses, a well-known phenomenon in coherent imaging. The method allows extraction of various medical parameters, such as blood pulse pressure, temporal signature of heartbeats and breath. The current work contains further development and application of the speckle tracking technique for remote detection and quantification of swallowing and distinguishing between sucking and swallowing to identify feeding disorders in infants and elderly individuals.

检测和评估摄入的能力在幼儿中尤为重要。因此，开发新的检测和准确测量摄入的方法非常重要。允许进行此类测量的方法之一是散斑图案分析，这是相干成象中众所周知的现象。该方法可以提取各种医学参数，例如脉搏血压、心跳和呼吸的时间特征。目前的工作包含了对散斑跟踪技术的进一步开发和应用，用于远程检测和量化吞咽，并区分吸吮和吞咽，以识别婴儿和老年人的喂养障碍。
