  • Cross-calibration for quantitative functional imaging
    Patent number: 10492737
    Abstract: Cross-calibration is provided for functional imaging. In PET or SPECT, the inaccuracies from the dose and detector sensitivity may be reduced or removed in both activity concentration and uptake. By using measures from both the radiotracer for the patient and factory calibrated sources, the variability due to dose may be removed. In SPECT, a measurement of system specific sensitivity to a factory calibrated point source is used to improve the accuracy of uptake values, not just activity concentration.

    Patent number: 10471018
    Abstract: A computer-implemented method for image-guided delivery of a nanoparticle mixture to a target tumor located in a region of interest includes selecting a non-hypoxic delivery location within the region of interest for delivery of a non-bacteria-associated nanoparticle component included in the nanoparticle mixture and selecting a hypoxic delivery location within the region of interest for delivery of a bacteria-associated nanoparticle component included in the nanoparticle mixture. An image-guided delivery and monitoring process may then be performed.

  • Shadow suppression in ultrasound imaging
    Patent number: 10456116
    Abstract: Shadow suppression is provided in ultrasound imaging, such as in steered spatial compounding. Using a transform or other approach, the data of a frame of data along the steering direction is projected. The projection is used to determine weights. The frame is weighted with the projection-based weights, reducing or removing shadows based on the one frame rather than based on registration with other frames. In the steered spatial compounding example, a compounded frame with independently shadow suppressed component frames may have little or no fork-like image artifacts due to shadowing.

  • FREQUENCY SWEEP FOR ACOUSTIC RADIATION FORCE IMPULSE
    Publication number: 20190298312
    Abstract: Frequency is swept in acoustic radiation force impulse (ARFI) scanning. Different frequencies are used at different times during the ARFI. For example, different frequencies are focused to different depths in the ARFI transmit beam. Since the frequency sweep is used for the ARFI pushing pulse rather than a transmit pulse for which echoes are received, the rate of change of the frequency is not dictated by the speed of sound. The rate of change of the frequency may be adjustable or set based on other factors, such as the type of tissue. In combination with a time varying focal position, the frequency sweep may better compensate for loss as compared to a focus sweep alone. The frequency sweep may better compensate for loss as compared to a single point focus ARFI.

  • ADAPTIVE CLUTTER FILTERING IN ACOUSTIC RADIATION FORCE-BASED ULTRASOUND IMAGING
    Publication number: 20190282212
    Abstract: For clutter reduction in ultrasound elasticity imaging, the contribution of clutter to different frequency components (e.g., the transmit fundamental and the propagation generated second harmonic) is different. As a result, a difference in displacements determined at the different frequency bands is used to reduce clutter contribution to displacements used for elasticity imaging.

  • Manufacture of an acoustic array with a shape alloy
    Patent number: 10405830
    Abstract: A memory alloy is used during manufacture of a transducer. The memory of the alloy may correct for deviations or bending during manufacture, such as a superelastic alloy returning an array to a flat state after being twisted during handling. The memory of the alloy may cause a desired change in array geometry during manufacture, such as a shape memory alloy twisting an array into a curved or helix due to applied heat. The array may be fixed in place by the memory alloy or bonding after positioning by the memory alloy, preventing further substantial alteration.

  • Respiratory motion estimation in projection domain in nuclear medical imaging
    Patent number: 10398382
    Abstract: In nuclear medical imaging, respiratory motion is corrected. Rather than pairwise estimation of motion from projection views, a sequence-based technique is used to jointly estimate parameters for a motion model across many projection views. In one approach, this sequence-based method is iteratively solved with a maximum likelihood objective function incorporating the motion model. A surrogate respiration signal is used to gate for the joint estimation and used to convert gated motion parameters to temporal motion parameters.

  • Motion correction in three-dimensional elasticity ultrasound imaging
    Patent number: 10390796
    Abstract: Three-dimensional elasticity imaging is provided. Motion in three-dimensions due to sources other than the stress or compression for elasticity imaging is found from anatomical information. Objects less likely to be subject to the stress or compression and/or likely to be subject to undesired motion are used to find the undesired motion. This anatomical motion is accounted for in estimating the elasticity, such as removing the motion from echo data used to estimate elasticity or subtracting out the motion from motion generated as part of estimating elasticity.

  • Model-based scatter in multi-modality multi-energy SPECT reconstruction
    Patent number: 10395353
    Abstract: In SPECT reconstruction, multi-modal reconstruction is combined with model-based multi-energy image formation. The scatter modeling of the model-based image formation uses resampling to facilitate convolution with the scatter kernels while maintaining resolution for the multi-energy projection. This combination of multi-modal and model-based multi-energy image formation simultaneously addresses the inaccuracy of the image formation process for complicated energy spectra and image blurring due to degradation of resolution. Varying the reconstruction by iteration may provide some of the benefits while reducing computational burden.

  • Diffraction source compensation in medical diagnostic ultrasound viscoelastic imaging
    Patent number: 10376233
    Abstract: In viscoelastic imaging with ultrasound, the shear wave speed or other viscoelastic parameter is measured by tracking at the ARFI focal or other high-intensity location relative to the ARFI transmission. Rather than tracking the shear wave, the tissue response to ARFI is measured. A profile of displacements over time or a spectrum thereof is measured at the location. By finding a scale of the profile resulting in sufficient correlation with a calibration profile, the shear wave speed or other viscoelastic parameter may be estimated.

  • Contrast agent sensitive medical ultrasound imaging
    Patent number: 10376240
    Abstract: In contrast agent imaging, a beamformer and transducer scan a region of a patient having contrast agents. A detector detects the contrast agents with at least two different contrast agent imaging techniques from ultrasound data resulting from the scanning. A processor compares responses of the contrast agents detected between the at least two different contrast agent imaging techniques and selects a relative contribution of the at least two different contrast agent imaging techniques. The selection is based on the comparing. Contrast agent imaging of the patient is performed using at least one of the contrast agent imaging techniques. The performance is based on the selected relative contribution.

  • Quantitative viscoelastic ultrasound imaging
    Patent number: 10376242
    Abstract: Viscosity is included in the quantification by an ultrasound imaging system. The log of a spectrum of displacement as a function of time is determined for each of various locations subjected to a shear or other wave. Solving using the log as a function of location provides the complex wavenumber. Various viscoelastic parameters, such as loss modulus and storage modulus, are determined from the complex wavenumber.

    Patent number: 10368850
    Abstract: Systems and methods are provided for utilizing an MRI image and real-time an ultrasound images to guide and/or restrict the movement of an ultrasound probe in position for collecting a biopsy core. A real-time ultrasound image is acquired and fused with pre-operative imaging modalities, such as an MRI image, to provide a three-dimensional model of the prostate. A multi-link robotic arm is provided with an end-effector and an ultrasound probe mounted thereto. Sensor information is used to track the ultrasound probe position with respect to the 3D model. The robotic arm allows for the implementation of a virtual remote center of motion (VRCM) about the transrectal probe tip, an adjustable compliant mode for the physician triggered movement of probe, a restrictive trajectory of joints of the robotic arm and active locking for stationary imaging of the prostate.
