Significant nonuniformities in the acoustic intensity distribution generated by physiotherapy ultrasound treatment heads are not uncommon, potentially leading to significant localised temperature rises and tissue damage. An acoustic absorber tile containing a thermochromic pigment has been developed to provide rapid quality assurance of physiotherapy ultrasound treatment heads by virtue of a thermochromic colour change, indicating the time-averaged intensity distributions generated by these… CONTINUE READING
