High resolution intravascular ultrasound (H-IVUS)

A high-resolution intravascular ultrasound (H-IVUS) transducer assembly comprising:

• a printed circuit having one or more electrical signal conditioners, each of the one or more electrical signal conditioners comprising one or more front-end interface amplifiers and dual high voltage coupling capacitors in series;
• and
• one or more convertors made of a polymer and configured to convert electrical energy to acoustic energy and acoustic energy to electrical energy,
• wherein the one or more convertors are interfaced to a pre-shaped receiving area of the printed circuit with at least a conductive material and shaped into a generally concave shape after being placed on the printed circuit,
• wherein the pre-shaped receiving area comprises a material that is permanently deformable under pressure and/or heat, wherein the material has at least one acoustic property that is complementary to at least one acoustic property of the polymer of the one or more convertors to convert electrical energy to acoustic energy and acoustic energy to electrical energy.
