  • Patent number: 7618374
    Abstract: 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.

  • Patent number: 7022080
    Abstract: The preferred embodiments described herein provide electrical and mechanical enhancements for a modular transducer system. In one preferred embodiment, a multiplexer is provided to reduce the number of circuits required to support a given transducer configuration. The multiplexer can be integrated into the scan head or the receptacle assembly of the modular transducer system. In another preferred embodiment, a scan head is provided with circuitry operative to compensate for mismatch in electrical impedance by increasing energy transfer between the transducer array and the cable assembly. In yet another preferred embodiment, a scan head is provided with circuitry operative to form a band pass filter programmable by the medical diagnostic ultrasound imaging system. With a further preferred embodiment, a scan head is provided with a non-volatile memory device. Some other preferred embodiments describe mechanical enhancements for the modular transducer system.

  • Patent number: 6969354
    Abstract: An intraoperative or endocavity ultrasound probe for insertion into a patient is provided. An adaptable or adjustable section is provided between the handle and the transducer for rotating the transducer relative to the handle prior to insertion within the patient. The adjustable or adaptable section maintains the adjusted or rotated position while the probe is in use within the patient. The adjustable or adaptable section stays in the same pre-bent position, such as by using a memory-less device or material, and is free of user adjustment while the probe is in use.

  • Publication number: 20040171935
    Abstract: Transducer probe identification is provided. A wireless identification is provided. For example, a radiofrequency identification tag is positioned within a transducer probe. A receiver is positioned within the imaging device. Using the wireless information, the imaging device may generate a list of available transducers regardless of whether they are connected with the imaging device. As an alternative or addition, information specific to a transducer is provided to the imaging device. Using either wireless transmission or a wired connection, the information distinguishes a given transducer from other transducers of a same type and manufacturer or from all other transducers. The specific identifier is then used with security information to prevent theft.

  • Patent number: 6659955
    Abstract: The preferred embodiments described herein provide medical diagnostic ultrasound imaging system transmitter control in a modular transducer system. With these preferred embodiments, transmitters in a medical diagnostic ultrasound imaging system are enabled only when contacts in a scan head are electrically coupled with contacts in a receptacle assembly of a modular transducer system. This prevents high voltages from developing in the receptacle assembly when the scan head is removed from or is not fully engaged with the receptacle assembly. In one preferred embodiment, a detector is used to detect movement of a member comprising the contacts in the receptacle assembly. Other preferred embodiments are provided, and each of the preferred embodiments described herein can be used alone or in combination with one another.

  • Patent number: 6511427
    Abstract: 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).

  • Patent number: 5882310
    Abstract: A plurality of ultrasound imaging system receptacles are arranged either vertically one above the other or horizontally side-by-side, each receptacle having an insertion slot for receiving the contact pads of an inserted ultrasound transducer connector. All of a number of connectors may be inserted into corresponding receptacles, and the system functions to mutually exclusively engage a single receptacle with its inserted connector. An electrical circuit arrangement is provided for automatically sensing the transducer in use without an operator having to make the selection manually. An interconnect and actuation scheme permits the multiport connector/receptacle arrangement to be manufactured at low cost. The modest size of the connectors and the receptacle assembly allows their placement at convenient locations on the system, and the simple basic design of the connector allows for submersion in liquid disinfectants.

  • Patent number: 5865650
    Abstract: An ultrasound adapter assembly includes a rectangular zero-insertion-force receptacle, such as the ITT Cannon.RTM. DL-series Zero Insertion Force ("DL-ZIF") receptacle, and a high-density micro-coaxial ("HDMC") connector plug interconnected by micro-coaxial conductors. The adapter assembly includes a frame for supporting the two connectors and a locking mechanism for use in semi-permanently attaching the adapter assembly to an ultrasound imaging system receptacle. The adapter assembly permits old-style ultrasound transducer assemblies having the rectangular zero-insertion-force plug to be used with newer ultrasound imaging systems using the newer HDMC interfacing system. In an alternative embodiment, the two connectors are electrically interconnected using flex-circuit. The HDMC connector plug is formed using a multi-layer printed wiring board having a high density array of electrical contact pads on one surface arranged for compatible mating with the newer system HDMC interfacing receptacle.
