The present invention relates to a method for producing an intravascular ultrasonic transducer and a structure for same, the method for producing a ultrasonic transducer producing a single element by: forming a piezoelectric element lapped according to a previously set thickness; depositing conductive material on the lapped surface of the piezoelectric element; forming a matched layer and a rear surface layer by casting the front and rear surfaces of the piezoelectric element to which conductive material has been deposited; lapping according to a previously set thickness; and dicing the bulk material, which is a stack of a matched layer, a piezoelectric element and a rear surface layer, along the stack direction so that the size of the element is less than the critical size for intravascular ultrasound (IVUS).

Method for producing intravascular ultrasonic transducers and structure thereof

An intelligent agent system comprising terminal devices and, a control method are disclosed. The control method for the intelligent agent system comprises the steps of: transmitting, by a first terminal device, data including context information of a user to a server; storing, by the server, the received data in a user profile; receiving, by the second terminal device, the data including the context information of the recognized user from a server, when a second terminal device recognizes the user; and detecting, by the second terminal device, current context information of the user and recommending a service to the user on the basis of the detected current context information of the user, the received context information, and the characteristics of the second terminal device.
