Abstract
Disclosed is an optoacoustic probe with a coated transducer assembly. The probe includes a transducer assembly with a multi-layer coating on the active end thereof. The multi-layer coating includes a layer of parylene and at least two layers of metal. In an embodiment, the multi-layer coating includes a layer of nickel, at least one layer of parylene, and a layer of gold.
Claims22
An optoacoustic probe with a coated transducer assembly, the probe comprising:
- a transducer assembly having an active end, the transducer assembly comprising a plurality of transducer elements;
- a multi-layer coating on the active end of the transducer assembly, the multi-layer coating comprising at least one layer of parylene, and at least two layers of metal;
- and
- a housing having a distal end and housing the transducer assembly and a plurality of other components, at least one of the housing and one or more of the plurality of other components securing the transducer assembly such that the active end of the transducer assembly is at the distal end of the housing.
A multi-layer coating for an acoustically coupling portion of an optoacoustic probe, the multi-layer coating comprising a layer of nickel, at least one layer of parylene, and a layer of gold.
A method of providing a durable gold coating to an RTV silicon rubber acoustic lens, the method comprising the steps of:
- coating the acoustic lens with a first continuous layer;
- coating the first continuous layer with a second continuous layer;
- and
- coating the second continuous layer with a layer of gold;
- wherein the first continuous layer is selected from the group consisting of:
- parylene and nickel.
