The processing system is configured to activate the vibration source to induce in the anatomy a first shear wave at a first frequency and a second shear wave at a second frequency, activate the ultrasound transducer to obtain ultrasound data representative of the anatomy that exhibits the first shear wave and the second shear wave, determine a first wave speed of the first shear wave and a second wave speed of the second shear wave, and determine the viscosity of the anatomy by comparing the first wave speed and the second wave speed.

Abstract: An ultrasound imaging system transmits two beams in succession in the same beam direction, the waveform of the second beam being a phase inverted form of the first waveform, and each waveform containing first and second major frequency components. Echoes are received from along the beam direction in response to each beam transmission, and are processed by additively and subtractively combining the two echo sequences on a common depth basis. The echo components resulting from this processing extend from high frequencies for good near field resolution to low frequencies for good depth penetration, and include fundamental, harmonic, and sum or difference frequency components. The linear and nonlinear echo signal components may be frequency compounded for speckle reduction.

Abstract: Techniques for predicting fluid responsiveness or fluid unresponsiveness are described. A processor can determine a first prediction of fluid responsiveness or unresponsiveness based on a plethysmograph variability parameter associated with a plethysmograph waveform, and can determine a second prediction of fluid responsiveness or unresponsiveness based on a fluid responsiveness parameter that is associated with an elevation of one or more limbs of the patient. The processor can determine an overall prediction of fluid responsiveness or unresponsiveness based on the first and/or second predictions. Based on overall prediction, the processor can cause administration of fluids and/or termination of administration of fluids.

Abstract: An optically computed optical coherence tomography (OC-OCT) technology is disclosed. The OC-OCT system performs depth resolved imaging by computing the Fourier transform of the interferometric spectra optically. The OC-OCT system modulates the interferometric spectra with Fourier basis function projected to a spatial light modulator and detects the modulated signal without spectral discrimination. The optical computation strategy enables volumetric OCT imaging without performing mechanical scanning and without the need for Fourier transform in a computer. OC-OCT performs Fourier transform signal processing optically, without the need of mechanical scanning, and before data acquisition unlike traditional OCT methods and systems. The scan-less OCT imaging is achieved through the use of spatial light modulator (SLM) that precisely manipulates light wave to generate output with desired amplitude and phase.

Abstract: A magnetic resonance imaging apparatus captures a morphology image and a function image that are captured with respect to an equal imaging region of an object under examination. Processing for deforming the morphology image is performed using a deformation parameter and moving positions of structural objects included in the morphology image to respective positions of structural objects of a previously determined standard morphology. Then, the function image is deformed using a value of the deformation parameter used in deforming the morphology image to cause a position of a region included in the function image to coincide with a position of a corresponding region of the standard morphology or by using the standard morphology in an opposite direction using the value of the deformation parameter to cause a position of a region of the structural object thereof to coincide with a position of a corresponding region included in the function image.

The ultrasound imaging apparatus is provided with a position estimator for estimating the position information of the ultrasonic source, and the position estimator analyzes a grating lobe artifact (false image) that is generated by the ultrasonic wave emitted from the ultrasonic source outside the imaging area, to estimate the position information of the ultrasonic source with respect to the imaging area.

Abstract: An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region which are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce a “thick slice” image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. Thick slice images are displayed at a high frame rate of display by combining a newly acquired slice with slices previously acquired from different elevational planes which were used in a previous combination. A new thick slice image may be produced each time at least one of the slice images is updated by a newly acquired slice. Frame rate is further improved by multiline acquisition of the slices.

Abstract: The invention relates to a marker device and a tracking system for tracking the marker device, wherein the marker device comprises a rotationally oscillatable magnetic object and wherein the rotational oscillation is excitable by an external magnetic field, i.e. a magnetic field which is generated by a magnetic field providing unit 20, 31 that is located outside of the marker device. The rotational oscillation of the magnetic object induces a current in coils, wherein based on these induced currents the position and optionally also the orientation of the marker device is determined. This wireless kind of tracking can be carried out with relatively small marker devices, which can be placed, for instance, in a guidewire, the marker devices can be read out over a relatively large distance and it is possible to use a single marker device for six degrees of freedom localization.
