摘要:
A hand-held transducer probe is overlapped with elastomeric material for improving the friction and softness of the grip of the probe. The elastomeric material comprises a biocompatible material having a tear strength in excess of 110 pounds per inch and a hardness level less than approximately shore A 80. Also disclosed is a method of producing a hand-held transducer probe having an improved grip comprising the steps of assembling an acoustic array and cable assembly; attaching a handle portion over aid acoustic array and cable assembly; and attaching an elastomeric material over at least a portion of said handle portion.

摘要:
A system and method for diagnostic ultrasound imaging with a probe combining one or more ultrasound imaging transducer elements and a body-tissue parameter measurement mechanism to detect body-tissue properties. At least one ultrasound transducer element provides an ultrasound image field of view of at least a portion of the body-tissue being measured by the parameter measurement mechanism. The parameter measurement mechanism is typically a mechanically or electrically operated mechanism attached to the probe near at least one ultrasound transducer element in order to combine information from the body-tissue parameter measurement mechanism and ultrasound transducer element for easier identification of abnormal body-tissue properties (e.g., tumors, dead, or diseased body-tissue).
摘要:
There is provided a two-dimensional array for use in an acoustic imaging system which comprises a plurality of transducer segments each having a trace for exciting an electrode on each of the transducer segments, the trace and the electrode being formed of the same material. The two-dimensional array disclosed is capable of imaging deeper in the human body at higher frequencies and provides more reliable lead attachments to the respective segments forming the array. Methods of manufacturing the two-dimensional array are further provided.

摘要:
A position of an imaging plane relative to a catheter or other probe is aligned with tissue of interest. Ultrasound tissue images may be registered to the catheter position with minimal rotational ambiguity. The spatial position of an ablation catheter or other device with respect to the imaging plane is more accurately determined, allowing a physician to identify specific anatomy in the relative location of a catheter or catheters. Another alternative or additional approach to determining the position of an imaging plane is to determine the relative position of two or more catheters. A catheter associated with imaging is then moved or bent in a direction having a known spatial relationship with the imaging plane. The position of the catheter is relative to each is then determined again to determine the angle or position of the imaging plane. In addition or as an alternative to determining an angular position of an imaging plane relative to a catheter, an ultrasound image of tissue is generated with acoustic elements for position identification. The acoustic elements are used as an imaging transducer array as well as devices for determining relative positions of the catheters.
摘要:
A low mass in the acoustic path flex circuit that has a thin metal layer in the acoustic path area and thicker electrical traces. The low mass flex circuit allows for mass termination of the signal and ground traces with the electrodes of the piezoelectric piezoelements. Regions that are to be diced are reduced in thickness to decrease the loading on the dicing blade during fabrication.
摘要:
An ultrasonic transducer assembly includes a shaft carried by the support element of the transducer assembly. This shaft supports an array of contacts that extend circumferentially around the shaft and are spaced axially along the length of the shaft. These contacts are electrically connected to conductors which are in turn connected to an ultrasonic transducer array. The shaft of the transducer assembly is received in a receptacle that includes a reciprocating slide that can be opened to insert and remove the transducer assembly from the receptacle. The slide can be closed to lock the transducer assembly in place, and to make electrical contact with the contacts of the shaft.
摘要:
A phased array transducer and method for the manufacture thereof having a design that allows the array to focus in a near field of interest and a far field of interest. The array includes a plurality of even and odd numbered transducer elements where the even and odd numbered elements have an active region of particular widths. The width of the active region of the odd numbered elements is different than the width of the active region of the even numbered elements so that the odd numbered elements can be used to image in one field of interest while the even numbered elements can be used to image in another field of interest.
