FLÜSSIGES UND FESTES GEWEBE-IMITIERENDES MATERIAL FÜR ULTRASCHALL-PHANTOME UND VERFAHREN ZU SEINER HERSTELLUNG

摘要

A tissue mimicking material for ultrasound phantoms has ultrasound speed and attenuation characteristics that are characteristic of human tissue and well suited for use in measuring and calibrating the potential biological effects of ultrasound equipment. The material is formed of an aqueous mixture of large organic water soluble molecules condensed from skim milk with a total solids content in the range of 10% to 30% by weight. The total fat content is less than 1% by weight, with the residual lipid particles of a size sufficiently small to remain in suspension without agglomerating and separating from the mixture over extended periods of time.
