摘要： An ultrasound imaging system that can automatically adjust the imaging parameters based on the original or processed received echoes from the target is presented in this disclosed technology. The adjustment is done through a closed loop negative feedback control system iteratively. Imaging performance evaluation parameters calculated from the received echoes, original or processed, are compared with preset thresholds that represent desired optimal imaging performances. The differences are used to calculate the adjustment for the imaging parameters. The system reaches to an optimal system image quality for the current target or stops when a maximum number of iterations is reached.

摘要： Jittering in medical diagnostic ultrasound imaging is reduced, such as in steered spatial compounding. A pattern of decorrelation is used to detect motion between component frames, register component frames, and/or reduce jitter in the motion correction. The ultrasound imaging adapts as a function of the pattern.

摘要： A halo surrounding the ultrasonic image of a liver tumor is automatically evaluated by detecting the boundary of the tumor and defining two annular regions around that boundary. The brightness of pixels in the two annular regions are compared to determine if a halo of darker pixels surround the tumor. Presence of this halo is indicative of a malignant tumor.

摘要： Certain embodiments of the present invention provide a method and system for improved ultrasound imaging using single transmission coded excitation. Certain embodiments include encoding a first ultrasound beam with a first code, transmitting the first ultrasound beam on a first path, encoding a second ultrasound beam with a second code, transmitting the second ultrasound beam on a second path and receiving echo signals from the first and second ultrasound beams. The codes may be complimentary Golay codes or other complimentary codes. The first and second paths may be adjacent scan lines. The method may also include match filtering the echo signals with corresponding matched filters. Match filtered echo signals along adjacent scan lines may be filtered, such as with a lateral averaging filter or other finite impulse response filter. Alternate complementary code transmission helps preserve or improve frame rate while maintaining signal-to-noise ratio improvement and range lobe cancellation.

摘要： The contrast-to-tissue ratio is improved while imaging contrast infused tissue. A subject is infused with contrast medium having microbubbles at a fundamental frequency. First and second transmit pulses are transmitted into the subject. The first and second transmit pulses each comprise first, or basic, and second, or seed, signals. The basic signal has a frequency based on the fundamental frequency and the seed signal has a subharmonic frequency based on the frequency of the basic signal. The first and second transmit pulses are phase inverted with respect to each other. Received echoes from first and second transmit pulses are filtered at a subharmonic or ultraharmonic frequency to remove tissue response and pass microbubble response.

摘要： A portable ultrasound imaging system employs a mechanically focused multi-element circular annular transducer that is mechanically scanned using a motor. Received echoes are processed to form two dimensional gray scale B mode images or two dimensional color tissue flow images which are displayed on a display unit. In case of color flow imaging, a high pulse repetition frequency imaging sequence is employed for a reasonable frame rate and special down-sampling techniques are applied to achieve an effective low pulse repetition frequency for flow estimation with enough signal to noise ratio. The system also includes a docking subsystem which charges a system battery and transfers patient and image data between a PACS system, workstation or other information system and the portable ultrasound imaging system.

摘要： Diagnostic ultrasound flow imaging is performed with coded excitation pulses. Due to the use of frequency coded excitation pulses, flow information may suffer from spatial misregistration and estimate errors. Spatial position shift in flow data is offset for alignment with B-mode or other imaging. The flow estimates are compensated for the imaging center frequency variation with depth. The wide bandwidth information available due to coded excitation may allow anti-aliasing by estimating velocities from two frequency bands.

摘要： A method and apparatus in an ultrasound imaging system is disclosed that enhances the contrast-to-tissue ratio and signal-to-noise ratio of contrast imaging using stepped-chirp waveforms. The first waveform component is employed with a first frequency optimized to initiate the bubble dynamics and the second waveform component is employed with a second frequency optimized to produce an enhanced bubble nonlinear response. The first waveform component and the at least a second waveform component are transmitted as a single stepped-chirp transmit pulse. At least one of a center frequency, an amplitude, a starting phase, and a bandwidth of the waveform components are adjusted to generate the single stepped-chirp transmit pulse. A relative phase, a switch time, and a time delay between the waveform components are also adjusted for maximal enhancement of bubble nonlinear response.
