摘要： A handheld ultrasound instrument is disclosed having enhanced diagnostic modes including pulse/continuous wave Doppler, time-motion analysis, spectral analysis and tissue harmonic imaging. An external electrocardiograph (ECG) recording unit is also disclosed. The ECG unit is adaptable to be used with the handheld ultrasound instrument to provide for ECG monitoring while performing an ultrasound scan in B-mode, Doppler, color Doppler, M-mode, and CW/PW mode. The enhanced handheld ultrasound instrument further includes a security mechanism allowing any combination of the diagnostic modes to be enabled by the manufacturer, and later to enable or disable any one or group of the diagnostic modes. The invention also discloses a method for a manufacturer to maintain a database of handheld ultrasound instrument capabilities after the instruments enter the stream of commerce.

摘要： The present disclosure is directed to systems and methods which allow for ultrasound parameter estimation to occur at specific advantageous sets of points in a two- or three-dimensional field of view within re-configurable, massively parallel, programmable architectures that can accommodate the input/output streaming, data movement or storage, and computation requirements. In one embodiment, a power efficient system is used for processing the data thereby increasing the ability of the system to be used for hand carried or mobile ultrasound applications. One aspect of the concepts discussed herein is the architectural aspects which provide the ability to simultaneously accept a large number of channels of data characterized by a continuous, simultaneous flow at high sample rates. The input data is routed at high rates to a distributed and large number of processing elements, memory, and connections for simultaneous parameter estimation at multiple points in the field of view. The ability to route the same data to multiple places enables high frame rates and allows for the streaming of data through the architecture.

摘要： A hand held ultrasonic instrument is provided in a portable unit which performs both B mode and Doppler imaging. The instrument includes a transducer array mounted in a hand-held enclosure, with an integrated circuit transceiver connected to the elements of the array for the reception of echo signals. A digital signal processing circuit performs both B mode and Doppler signal processing such as filtering including wall filtering matrix and Hartley transform matrix functions, detection and Doppler estimation, as well as advanced functions such as assembly of multiple zone focused scanlines, synthetic aperture formation, depth dependent filtering, speckle reduction, flash suppression, and frame averaging. The advent of color flow imaging based on Doppler frequency estimation in medical ultrasound addresses a need for rapid assessment of overall flow characteristics in cardiac care. Typical prior art implementation utilize a high degree of temporal filtering in order to enhance the flow signal, but makes the image slow to respond to changes in flow. This is true of both directional and non-directional implementations, and is necessitated by the instability of traditional estimation techniques that are derived from older color flow techniques. A significant advantage of the present invention is excellent stability of both power and direction estimates.

摘要： An ultrasonic diagnostic imaging system is provided with scanheads having a reduced size cable by virtue of the performance of at least some of the beamforming in the scanhead. The need to individually couple signals from all of the elements of the transducer array of the scanhead is eliminated, and the size of the scanhead cable correspondingly reduced, by the coupling of combined, beamformed signals through the cable to an ultrasound system.

摘要： An ultrasonic diagnostic imaging system is provided with cordless scanheads which wirelessly transmit ultrasonic image signals to the imaging system. The transmitted image signals are received by a receiver in the mainframe ultrasound system where they undergo further image processing and are displayed. In a preferred embodiment the scanhead image signals are at least partially beamformed in the scanhead before being transmitted to the ultrasound system, thereby reducing the required transmission bandwidth. The cordless scanheads are battery powered, and are recharged by the ultrasound system when the scanheads are not being used for scanning.
