Frequent monitoring of blood glucose levels is an essential part of diabetes care, but the invasiveness of current devices deters regular measurement. Noninvasive measurement techniques are painless to implement and rely on changes in sample properties to estimate glucose concentration. However, such methods are affected by the presence of different biomolecules, resulting in an increased estimation...
Near infra red photoacoustic measurements can be used to estimate blood glucose concentration in a non-invasive manner. A multi-wavelength photoacoustic measurement apparatus operating at 905 nm and 1550 nm is used to obtain measurements from glucose solutions with concentration in the physiological blood glucose range (0–500 mg/dl). Amplitude and area based features computed from photoacoustic measurements...
The use of near infra red (NIR) photoacoustic spectroscopy (PAS) for continuous non-invasive glucose measurement is outlined in the paper. A photoacoustic (PA) measurement apparatus was constructed and PA measurements were made on glucose solutions at multiple NIR excitation wavelengths. A variety of time and frequency domain features, including amplitude and area based features, were extracted from...
The paper examines the use of photoacoustic spectroscopy (PAS) for making continuous non-invasive blood glucose measurements. An apparatus for performing photoacoustic (PA) measurements is constructed and the technique is verified in vitro and in vivo through measurements on glucose solutions and live tissue. The signal amplitude is observed to increase with the glucose concentration in both cases...
This paper presents a method for improvement in SNR and resolution of photo acoustic (PA) signal using Golay coded excitation for a non-invasive and continuous glucose monitoring. The simulation results with a Golay code of length 4 has been shown, which gives a coding gain of 9.03 dB in comparison to regular pulse triggering. Furthermore, Golay coded excitation results in better resolution of PA...
Ultrasound Imaging is a popular modality for better diagnosis and treatment of various diseases. So there is a need to educate a large number of people coming from different backgrounds about Ultrasound Image Processing. The aim of this project is to help beginners in the field of Ultrasound Image Processing to enhance their domain knowledge by making information about Advanced Ultrasound Image Processing...
