An interconnect is provided for a multidimensional transducer array. An adaptor provides a 90-degrees or other non-zero angle transition of conductors from connection with the elements to connection with a printed circuit board. The adaptor is formed as a component that may surface mount on the printed circuit board and may provide a pitch change from the element pitch to a different pitch, such as a pitch of conductors of an integrated circuit also mounted to the printed circuit board. The adaptor allows stacking of modules where each module uses standardized or regular printed circuit board connections.

Modular assembly for multidimensional transducer arrays

Sub-performing elements of an ultrasound transducer array are detected. The power, such as current, used by or provided to the transmit driver is measured. By driving each element or group of elements separately, defective elements or groups of elements are detected from the amount of power used.

Sub-performing transducer element detection for medical ultrasound

In order to position and simultaneously operate both a magnetic resonance (MR) coil and an ultrasound transducer adjacent to a target volume while minimizing interference between the MR coil and the ultrasound transducer, hybrid ultrasound and magnetic resonance imaging (MRI) devices are provided. One of the hybrid ultrasound and MRI devices includes a transducer array, a communications interface connected with the transducer array, and a housing that electromagnetically shields and encloses the transducer array and the communications interface. An electrically conducting side of the housing receives a radio frequency (RF) signal from an MRI system and transmits the RF signal to an electrically conducting side of a housing of another of the hybrid ultrasound and MRI devices.

Hybrid ultrasound and magnetic resonance imaging device

Scan timing of contrast agent study is provided. Ultrasound is used to determine timing of contrast agent inflow and/or outflow. The timing based on the ultrasound scanning controls scanning for MR or CT imaging. The MR or CT contrast agent imaging for MR or CT contrast agents may be synchronized using the ultrasound contrast agent flow.

System scan timing by ultrasound contrast agent study

Medical diagnostic ultrasound stereo imaging is provided. A medical diagnostic ultrasound system operable to scan a body with ultrasound is also operable to generate a three dimensional stereoscopic view of the body. The video processing unit and/or display device create the stereoscopic display.

Stereoscopic three or four dimensional ultrasound imaging

Ultrasound transducer temperatures are measured in response to a temperature dependent property of the ultrasound transducer. The temperature is measured without addition of new electronics or hardware retrofits of the transducer. By implementing software and/or hardware on the ultrasound system rather than the transducer, the temperature is measured in order to provide a level of fault protection. The upgraded or new ultrasound system uses either old or new transducers while still providing temperature measurement. For example, the temperature of the lens or window is measured as a function of changes in attenuation or acoustic velocity. The receive beamformer already implemented on many ultrasound systems is used to measure a temperature dependent property of the lens or window. As another example, the dielectric constant or capacitance of one or more transducer elements is measured using additional hardware in the ultrasound system. The signal line and associated cable for one or more piezoelectric elements is switchably connected between hardware for measuring a capacitance and the receive beamformer for imaging. Rather than temperature, the operational state of the transducer may be diagnosed using acoustic energy response of the lens.

Ultrasound transducer fault measurement method and system

A segmented ultrasound system is provided. Ultrasound data, such as image data in a video format, is wirelessly transmitted to a multi-use display device from a handheld ultrasound device. Any of various multi-use display devices may be used, such as personal digital assistants (PDA), tablet computers, lap top computers, or personal computers.
