[305898] Metrological evaluation of ultrasonic velocity in oils for commercial phantom development
Autores: Mylena Kathleen Mosqueira de Assis, Rodrigo Pereira Barretto da Costa Félix
Resumo: This study focuses on the metrological evaluation of ultrasonic velocity in materials to develop Tissue Mimicking Materials (TMM). TMMs are essential for assessing ultrasound equipment performance, safety, technical assessment, and studying the biological effects of ultrasound. Agar-based TMMs are commonly used but have limited durability, necessitating the development of commercially viable alternatives. Oil-based TMMs, such as mineral and lubricating, show promise due to their stability and favourable characteristics. The study aims to characterize the ultrasonic properties of oil-based materials, aiming to produce a stable TMM suitable for the transportation and evaluation of ultrasound diagnostic equipment. The results for each material were as follows: ethylene glycol (1727.0 + 4.6) m s-1, mineral oil (1397.0 + 5.7) m s-1, and lubricating oil (1472.0 + 4.7) m s-1. Thus, mineral oil and lubricating oil are the most suitable materials.
