Abstract:
This article explores the development of a device architecture for non-invasive monitoring of the human body's performance based on ultrasound measurements. The implementation of this architecture is carried out using programmable integrated circuits (FPGAs). Ultrasonic sensors are connected to the FPGA to make measurements. The purpose of the study is a detailed description of the architecture of the device under development. The proposed technical device is capable of detecting pathologies in the human vascular system at a precision stage, which in turn, with surgical treatment, can increase the life expectancy of an individual. Methodology. To ensure the correct functionality of the device with high accuracy, it is necessary to ensure sufficient processing speed of the data coming from each sensor and output of the result. To increase the accuracy of the measured parameters, it is necessary to install ultrasonic sensors in the form of a phased array. Since ultrasonic sensors are analog, it is necessary to use high-frequency digital-to-analog and analog-to-digital converters with high bit depth to obtain high-quality data. These transducers are connected to ultrasonic sensors via signal amplifiers. The proposed architecture provides optimal performance and flexible configuration for measuring ultrasonic signals using sensors. The results of the study. A device demonstrating high data processing speed has been developed and experiments have been conducted on its use. The device has a compact size, which allows you to carry it on yourself without restricting movement. The scope of application. The device is designed to study the work of the heart and human cardiac activity, and is used in the field of healthcare.
