Abstract: A low-loss high-voltage multiplexer is implemented using a transformer that is connected to one transmitter, one receiver and transducer elements. At least one primary winding is magnetically coupled at least two secondary windings. For example, a first transducer element and a second transducer element are connected to the secondary windings of a multiplexer that multiplexes between these transducer elements via the secondary windings. The multiplexer also optionally switches between the transmitter and the receiver during the transmission and the reception.

Abstract: The embodiments of the probe in the ultrasound imaging diagnostic apparatus include at least one rigid interface device for connecting a high-density acoustic array and a predetermined low-density device while maintaining one-to-one connection. The rigid interface provides a first connection area having a predetermined high density and a second connection area having a predetermined medium density that is lower than the high density. The second connection area offers a connection surface for connecting a predetermined low-density device having a predetermined low density that is lower than the medium density.

Abstract: The embodiments of the probe or the probe handle additionally include an integrally formed cooling structure with at least one dividing wall that is connected to an outer wall and an inner wall of the probe. The outer wall and the inner wall of the probe together form a medium flow space inside the probe, and the dividing wall divides the medium flow space into a continuous medium flow path where a predetermined medium travels to carry undesirable heat away from the probe handle. The undesirable heat is generated from electronic components and or an array of transducer elements in the probe handle.
