摘要： Method and apparatus for automatically adjusting a parameter used in the display of a Doppler spectral image comprises acquiring a plurality of spectral lines of Doppler data. A subset of Doppler data is determined from the plurality of spectral lines of Doppler data. A noise characteristic of the subset of Doppler data is calculated, and a signal characteristic of the subset of Doppler data is identified. The noise and signal characteristics are compared, and a system parameter is adjusted based on a result of the comparing step.

摘要： A method for monitoring a target in a medical display in a medical imaging apparatus includes receiving echo signals from an area of interest of a patient, extracting raw data from the received echo signals, processing the extracted raw data to display a dual mode image on the medical display, and setting a location and displaying a first marker/cursor in a first image of the dual mode image. In addition, the method further includes determining a corresponding location of the marker/cursor in a second image of the dual mode image, and displaying a second marker/cursor in the second image of the dual mode image at the corresponding location simultaneously with the displaying of the first marker/cursor in the first image.

摘要： A non-linear response may be measured by transmitting a first pulse at an amplitude and transmit frequency, using an aperture having N elements. A first response is measured at a sub-harmonic frequency based on the transmit frequency. At least second and third pulses are transmit at the amplitude and transmit frequency. At least second and third responses are measured at the sub-harmonic frequency. The second and third pulses have the same phase with respect to each other and use first and second sub-apertures that have different ones of the N elements. A sum of the elements within the first and second sub-apertures is equal to N. Alternatively, at least two pulses having the same aperture and different amplitudes may be transmit, and the responses measured at the sub-harmonic frequency. The responses are combined to suppress linear echoes and determine a non-linear response.

摘要： An ultrasound transmitter generates ultrasound signals at an adjustable pulse repetition rate. A Doppler unit generates Doppler signals from ultrasound backscattered signals and stores them in a memory. A logic unit performs an algorithm which automatically adjusts the polarity and position of the velocity scale of a display and automatically adjusts the pule repetition rate of the transmitter based on analysis of the signals.

摘要： A method and an apparatus for automatically maintaining the Doppler sample gate position at a preselected vessel position in B-mode or color flow images during tissue or probe motion. The sample gate is locked onto the selected vessel automatically when the vessel position has changed. Optionally, the vessel slope cursor is automatically updated when the vessel position has changed. The method employs pattern matching of images from successive frames to determine how much a vessel in the image frame has been translated and rotated from one frame to the next. Preferably, either a cross-correlation method is applied to the imaging data in the spatial domain to determine the relative object translation and/or rotation between image frames, or a matched filtering method is applied to the imaging data in the frequency (i.e., Fourier) domain to determine the relative object translation and/or rotation between image frames.

摘要： A method for measuring a non-linear response from a target using an imaging apparatus includes transmitting a signal towards a region of interest from a transducer at a first amplitude and measuring a first response thereto, and transmitting, from the transducer towards the region of interest, at least one additional signal of the same phase as the first amplitude signal but at one or more different, lower amplitudes and measuring at least one additional response thereto. A difference of a function of the measured additional response or responses from the first response is determined, thereby obtaining a non-linear response of the object of interest, and a representation of the non-linear response is displayed.
