    摘要: Embodiments for performing surface rendering upon volume data in an ultrasound system are disclosed. An ultrasound data acquisition unit transmits and receives ultrasound signals to and from a target object to thereby acquire ultrasound data corresponding to a plurality of frames. A volume data forming unit forms volumes data corresponding to the plurality of frames based on the ultrasound data. The volume data includes a plurality of voxels. A processing unit detects edges of a region of interest (ROI) of the target object in the volume data and performs surface rendering upon voxels within the detected edges to thereby form a 3-dimensional ultrasound image.

    摘要: An ultrasonic imaging system has a probe with an even-numbered plurality of N of transducer elements, with one transducer element being present in each of a like plurality N of signal-processing channels, and with successive ones of the transducers polarized in alternating directions. The transducers require channel excitation drive signals which are either a positive-polarity pulse or a negative-polarity pulse, with signal polarity being dependent upon the polarity of the transducer in the particular channel. The processed outputs of each odd channel is connected directly to an associated input of a coherent summer while the processed output of each even channel is individually amplitude-inverted before connection to an associated summer of input. The summation means output is the sum of all channel transducer outputs, with suppression of any common-mode signal appearing anywhere in the system channels, from the transducer to the summation means inputs.

    摘要: An ultrasonic Doppler flow (e.g. blood) imaging and/or measuring system capable of adaptively suppressing stationary or slowly-moving non-flow (e.g. tissue) signals having variable spectra from the recovered ultrasonic echoes. In accordance with the invention, the tissue signals are suppressed using a tissue rejection filter arrangement having an attenuation characteristic which is controlled based upon measured estimates of at least one spectral characteristic of the tissue signals to be removed, thereby maximizing the rejection of tissue movement signals and minimizing undesired attenuation of the blood flow signals. In accordance with an embodiment of the invention, signal routing out of the corner-turning buffer memory component in prior art systems is advantageously modified, so as to provide during a first mode of operation, the echo signal data to a Doppler velocity processor, for forming estimates of tissue signal motion. These estimates are then used for developing a control signal for application to a tissue motion rejection filter arrangement. During a second mode of operation, the echo signal data are provided to the same Doppler velocity processor, however, this time via the tissue motion rejection filter arrangement. Thus, the estimates of tissue signal motion are developed in a simplified hardware arrangement, by using the same corner turning memory and Doppler velocity processing circuitry as is used for developing the blood flow velocity signals.

    摘要: Methods and systems are provided for identifying clinical markers in spatial compounded imaging. For example, an image responsive to less spatial compounding more likely preserves clinical markers than a steered compound image. By displaying both images, clinical markers are identified by the user from one image and other diagnostic information is obtained from the steered compound image. As another example, clinical marker information is identified and added back into or highlighted on a spatial compound image for identification by the user.

    摘要: An ultrasonic medical diagnostic apparatus for scanning an object at a predetermined rate and generating a two-dimensional anatomical map of a plane section thereof. A position-sensing transducer develops an electrical signal corresponding to the orientation of an ultrasonic transducer. A function generator is responsive to the electrical signal for generating a voltage proportional to the rate of change of position of the ultrasonic transducer. This voltage is applied to a voltage-controlled oscillator which in turn varies the transmission rate of an ultrasonic transmitter-receiver in accordance with the scanning rate of the ultrasonic transducer. A second function generator and oscillator subsystem, together with a switch, are employed to switch to the more accurate of the two subsystems.
