Anotācija: Subcutaneous adipose tissue (SAT) and intermuscular adipose tissue (IMAT) are two forms of body fat. The differential assessment of SAT and IMAT contents in sarcopenia and obesity by ultrasonic measurements is difficult due to their complex influence. In the present study, the possibility of using pattern recognition methods applied to ultrasonic measurement data to discriminate SAT and IMAT values was investigated on muscle tissue mimicking phantoms. The muscle mimicking phantoms were made of gelatin (muscle) with oil (fat) layers (SAT) and inclusions (IMAT) with gradually varying SAT and IMAT contents from zero to 50% with a step 12.5%. The set included a net of 25 phantoms with five grades of SAT and IMAT, each varied independently. Each phantom (object under study) passed multiple repeatable ultrasound tests. For each object, a set of parameters was extracted from the set of ultrasonic signals, including speed of sound, ultrasound attenuation at two frequencies and signal amplitude integrals. Decision rules were constructed for all objects based on the set of the extracted parameters. The efficiency of the constructed rules was checked using the signals of the examination object. The results of the experiments demonstrated the potential effectiveness of the proposed approach for determining SAT and IMAT values separately. © 2025 Elsevier B.V., All rights reserved.
