Thermal Testing Ultrasound Phantom ATS TTP-1

The ATS Laboratories Model TTP1 is designed to meet the testing requirements stipulated in IEC 60601-2-37 Amend 1.

The TTP1 is manufactured from a proprietary water-based tissue mimicking material which meets the acoustic and thermal characteristics specified in the above IEC document. As this material is water-based, it is subject to the effects of gradual dehydration. When the TTP1 is not is use the container cover should always be tightly in place.

The scan surface is a proprietary rubber-based tissue mimicking material with a thickness of 1.0-1.5 mm. It primarily serves the purpose of simulating a skin layer over underlying soft tissue and negates the need for using a slab of silicone rubber over the tissue mimicking material as called for I the IEC document. Secondly, the rubber layer seals the tissue mimicking material below and reduces the dehydration rate.

The test conditions and test methods used should be those contained in the IEC document.

Care:After use, a gentle wiping of the scan surface with a clean paper towel or Kimwipe should be sufficient to remove any residual coupling gel. Replace the cover of the container for storage at room temperature. Use caution to not push too hard on the scan layer while cleaning and breach its integrity.

The TTP1 is designed to be semi-disposable. With reasonable care, it should last several months. Pay particular attention to the edges of the scan surface for any indication that the tissue mimicking material is pulling away from the walls of the container, a clear sign of excessive dehydration.
