medical transducer fabrication

Greetings All,

I am interested in the design and fabrication of medical transducers.
Specifically my question today concerns the final material
applied onto the radiating face on the ceramic-matching layer combinations.
This material is commonly an RTV or a castable polyurethane, which is used to form lenses
and/or for further impedance matching and as a environmental barrier.
That much I believe to be correct. My question is on the specifics of these materials.
Who makes them? What are the common formulations?
Have their acoustic properties been reported? Where are they reported?

Thanks for your attention and any responses

Grant Gordon

Exertus Dual 120

The Exertus Dual 120 Projector has the ability to accept Iridium 192 sources or Selenium 75 source
...
s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
