Abstract

It is generally accepted that ultrasound has the potential to produce biologically significant temperature rises. At NPL, we have developed a thermal test object to enable the temperature rise produced by diagnostic ultrasound equipment to be measured experimentally. This report investigates the thermal and acoustic properties of potential bone mimics that are important when determining ultrasound induced temperature rises. An ideal foetal and adult bone specification is suggested, determined from the literature currently available, and suitable bone mimics are identified. Temperature rise predictions using the properties of the candidate bone mimics are then compared with those from the ideal specification. PTFE (glass-filled) is identified as a suitable adult bone mimic; high-density polyethylene is suggested as a foetal bone mimic.
