Nový MR-kompatibilní senzor dechové činnosti lidského těla založený na kombinaci Braggovské mřížky a konvenční kyslíkové masky

Abstract

This thesis explains the desing and subsequent development of a Bragg grating based sensor using a conventional full-face mask and EMI materials for monitoring a basic vital function of the human body, namely the respiratory rate. The sensor is characterized by innovative features for the biomedical field such as light weight and small size, easy implementation on the human body and the possibility of use in an MRI environment. The Bragg grating, its principle and basic properties are described in the theoretical part of the thesis. The practical part discusses the creation of a 3D model, the use of 3D printing and subsequent experimental measurements. That involved six male volunteers in whom the respiratory rate was monitored. The data obtained from the implemented FGB sensor was compared against a reference sensor. The Bland-Altman method was used for statistical analysis. According to the Bland-Altman method, the results of the experimental measurements were more than the required 95 % and the sensor was successfully tested.
