  • Patent number: 10813626
    Abstract: In spectral pulsed wave Doppler imaging, spatial variance in signal and/or noise are reduced by combination of multiple spectra with at least partially decorrelated noise. Rather than requiring oversampling in time, the multiple spectra for one Doppler gate are created from different spatial signals. The Doppler gate is divided into sub-gates, the beamformed sample locations in the Doppler gate are grouped into two or more groups using any selection criterion, and/or different receive apertures are used to simultaneously sample the Doppler gate. Spectra for the gate are estimated from the samples with the different spatial content and then combined.

  • Patent number: 10799208
    Abstract: For sound speed imaging, different receive apertures are used instead of multiple transmissions from different angles. Acoustic echoes from a same transmission are receive beamformed with different apertures of the transducer array. The axial shift between the beamformed signals from the different apertures is used to solve for the speed of sound at one or more locations. The resulting measure of the speed of sound is displayed as the speed of sound in the tissue and may be diagnostically or prognostically useful.

  • Patent number: 10792005
    Abstract: Anatomic range planning is provided in positron emission tomography (PET). The user indicates one or more ranges on an image of a patient based on anatomy. Rather than planning by bed position, the planning is based on the anatomy of the patient without reference to the length of the PET detector. The user interface for PET examination avoids overlapping boxes and other confusion based on bed position. Different anatomical ranges may be assigned different PET parameters, such as reconstruction parameters. A processor may automatically alter the examination (e.g., by extending the detection range beyond the region of interest or by increasing duration at an end position) to account for the sensitivity profile since the anatomical region of interest is known. Anatomical region specific directions may be included as part of planning, aiding in performing different protocols for different anatomical ranges.

  • Patent number: 10772582
    Abstract: For a multi-modal emission tomography system, an improved control system increases the likelihood of optimal image quality, satisfaction of physician goals, and/or avoids repetition in scanning and the corresponding increase in dose burden. The control system is divided into two or more arrangements. One arrangement receives goal information and outputs reconstruction settings and generic scan settings to satisfy the goal information. Another arrangement converts the generic scan settings to emission tomography system-specific scan settings, which are used to detect emissions. The separation of the arrangements allows independent operation so that different system-specific conversions may be used for different systems.

  • Patent number: 10772580
    Abstract: Single photon emission computed tomography (SPECT) is performed with multiple emission energies. For quantitative or qualitative SPECT, the image formation process for emissions at different energy ranges is modeled (44, 46, 48, 50) separately. Different scatter, different attenuation, and/or different collimator-detector response models corresponding to different energy ranges are used in the reconstruction.

  • Patent number: 10699445
    Abstract: For partial volume correction, the partial volume effect is simulated using patient-specific segmentation. An organ or other object of the patient is segmented using anatomical imaging. For simulation, the locations of the patient-specific object or objects are sub-divided, creating artificial boundaries in the object. A test activity is assigned to each sub-division and forward projected. The difference of the forward projected activity to the test activity provides a location-by-location partial volume correction map. This correction map is used in reconstruction from the measured emissions, resulting in more accurate activity estimation with less partial volume effect.

  • Patent number: 10675006
    Abstract: In multi-modality imaging fusion with ultrasound, one transducer is used for registering ultrasound scan data with scan data from another mode. This registration is used to then align scan data from a different ultrasound transducer with the scan data of the other mode. The alignment may account for differences in position sensing between the two transducers.

  • Patent number: 10675007
    Abstract: For noise reduction in elasticity imaging, frequency compounding is used. Displacements caused by the acoustic radiation force impulse are measured using signals at different frequencies, either due to transmission of tracking pulses and reception at different frequencies or due to processing received signals at different sub-bands. The displacements are (a) combined to compound and the compounded displacements are used to determine elasticity or (b) are used to determine elasticity and the elasticities from information at the different frequencies are compounded.
