МІКРОКОНТРОЛЕРНА СИСТЕМА ДЛЯ ДОСЛІДЖЕННЯ ЗМІН ЩІЛЬНОСТІ КІСТКОВОЇ ТКАНИНИ

Relevance. Early diagnosis of changes in bone tissue density is an important component of the prevention and treatment of musculoskeletal diseases, particularly osteoporosis and inflammatory processes in the periodontium. Traditional methods for assessing bone density are often associated with the use of ionizing radiation, high equipment costs, and limited availability, which complicates their application in rural areas and mobile medical practice. Object of study: processes of ultrasonic wave propagation in bone tissue. Purpose of the article: to develop a microcontroller-based system for preliminary assessment of changes in bone tissue density based on the analysis of the time delay of ultrasonic signal propagation. Research results. The article proposes an experimental microcontroller-based ultrasonic densitometry system that enables non-invasive preliminary analysis of bone tissue condition without the use of radiographic methods. The system provides measurement of ultrasonic signal delay time and real-time visualization of the results, features low power consumption, and supports autonomous operation powered by a compact energy source. Conclusions. The proposed system confirms the feasibility of using ultrasonic methods for preliminary assessment of bone tissue density and demonstrates potential for further improvement through increasing operating frequency, signal amplitude, and optimization of data processing algorithms. Scope of application of the obtained results: mobile and stationary systems for primary diagnostics of bone tissue condition, particularly in environments with limited medical infrastructure.
