Estimating the term…
An adhesion system specifically designed to achieve a good-quality adhesive bond between a silicone rubber lens and a plastic matching layer of an ultrasonic transducer. The adhesion system includes a layer of conventional silicone adhesive applied on the silicone rubber lens and a layer of dichloro-di-p-xylylene residing between the silicone adhesive and the plastic matching layer. The layer of dichloro-di-p-xylylene is adhered to the silicone adhesive via a silicone primer and is adhered to the plastic matching layer via a silane primer. The layer of dichloro-di-p-xylylene provides adhesion promotion, a chemical barrier to protect the transducer array from the external environment and an electrical barrier to help protect the patient from the electrically alive transducer elements, without any adverse effect on the acoustic transmission characteristics of the transducer stack.
An ultrasound transducer in the form of a stack of layers bonded one on top of another and comprising:
An ultrasound transducer in the form of a stack of layers bonded one on top of another and comprising:
An ultrasound transducer in the form of a stack of layers bonded one on top of another and comprising:
An ultrasound transducer comprising a plurality of layers bonded in a stack, said plurality of layers comprising a first layer bonded to a second layer by adhesive means, said adhesive means comprising a thin film consisting of a plastic material which is a member of the p-xylylene family.
A method for adhesively bonding a first layer of a first material to a second layer of a second material, comprising the steps of:
