MULTICOMPONENT BACKING BLOCK FOR ULTRASOUND SENSOR ASSEMBLIES

摘要

Backing block (16) for interconnecting a transducer array (12) and interconnection cables (18) connecting the transducer array (12) to a main system processing unit of an ultrasound imaging system which includes at least one base electronic component (24) electrically connected to the interconnection cable(s) (18) and which provides a pattern of interconnection structures (28), a redistribution interposer (22) electrically coupled on one side (40) to the base component(s) (24) and on an opposite side (38) to transducer array (12), and at least one subsidiary electronic component (26) supported by the base component(s) (24). The subsidiary components (26) can be arranged alongside the redistribution interposer (22), i.e., on a common side of the base component(s) (24) therewith, since the redistribution interposer (22) tapers in at least one dimension so that it has a smaller pitch on the side (40) connected to the base component(s) (24) than on the side (38) connected to the transducer array (12).
