Testing compliance of ultrasound transducers
The surface temperature test phantom can be used to test compliance with the limits of ultrasound transducer surface temperature specified in IEC 60601-2-37 Ed 2.
The phantom uses agar-based tissue-mimicking material (TMM), prepared strictly according to the recipe given in IEC 60601-2-37 Ed 2. The material contains scattering particles and was originally developed as part of a European Framework project for Doppler ultrasound testing.
The phantom is supplied with silicone rubber skin-mimicking layers of a range of thicknesses.
The dimensions of our standard cylindrical phantom are approximately 11.0 cm +/- 0.5 cm diameter, 11.5 cm +/- 0.5 cm height. These dimensions, particularly the height, could be tailored to suit customer requirements. We may be able to supply bespoke phantoms to help evaluate endocavity probes.
We can also supply gelatine-based, non-scattering TMM which follows a recipe in IEC 62306.
Additional information about the phantom:
- Meets requirements of IEC 60601-2-37 Ed 2.
- Agar-based TMM: Speed of sound approx. 1540 m/s, attenuation coefficient approx. 0.5 dB/cm/MHz.
- Gelatine-based TMM: Speed of sound approx. 1540 m/s, attenuation coefficient approx. 0.45 dB/cm/MHz.
