Abstract: For tissue property estimation with ultrasound, multiple different types of measurements are performed by an ultrasound system, including scatter measurements and shear wave propagation measurements. The tissue property, such as liver fat fraction, is estimated using a combination of these different types of measurements.

Abstract: For robust view classification and measurement estimation in sequential ultrasound imaging, the classification and/or measurements for a given image or sequence of images are gated. To prevent oscillation in results, the gating provides consistent output.

Abstract: For ultrasound-based proxy estimation with an ultrasound scanner, one or more ultrasound measurements are converted to a biomarker of a different modality, such as providing a measurement of a standard biomarker from histology or a lab test assay. The conversion uses a user-selected model, allowing for selection of one of various models relating ultrasound measurements to the biomarker. The ultrasound scan sequence may be optimized to the one or more biomarkers and the user-selected model. This improvement in use of ultrasound measurements relative to standard biomarkers may more likely result in acceptance of the less costly and more easily obtained ultrasound measures in diagnosis.

Abstract: A system and method include determination of a value of a first biomarker, determination of a value of a first quantitative parameter of a first imaging modality corresponding to the determined value of the first biomarker, determination of a value of a second quantitative parameter of a second imaging modality corresponding to the determined value of the first biomarker, determination of physical characteristics of an imaging phantom associated with the value of the first biomarker, the value of the first quantitative parameter, and the value of the second quantitative parameter, and generation of an instruction to fabricate the imaging phantom based on the physical characteristics.

Abstract: A system and method for multi-modality fusion for 3D printing of a patient-specific organ model is disclosed. A plurality of medical images of a target organ of a patient from different medical imaging modalities are fused. A holistic mesh model of the target organ is generated by segmenting the target organ in the fused medical images from the different medical imaging modalities. One or more spatially varying physiological parameter is estimated from the fused medical images and the estimated one or more spatially varying physiological parameter is mapped to the holistic mesh model of the target organ. The holistic mesh model of the target organ is 3D printed including a representation of the estimated one or more spatially varying physiological parameter mapped to the holistic mesh model. The estimated one or more spatially varying physiological parameter can be represented in the 3D printed model using a spatially material property (e.g.

Abstract: Imaging from sequential scans is aligned based on patient information. A three-dimensional distribution of a patient-related object or objects, such as an outer surface of the patient or an organ in the patient, is stored with any results (e.g., images and/or measurements). Rather than the entire scan volume, the three-dimensional distributions from the different scans are used to align between the scans. The alignment allows diagnostically useful comparison between the scans, such as guiding an imaging technician to more rapidly determine the location of a same lesion for size comparison.

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.

Abstract: To accurately generate the three-dimensional ultrasound data and/or determine the position of the ultrasound scan relative to pre-operative data, a tracking sensor is releasably connected with the ultrasound probe. The connection positions the tracking sensor near a distal end of the probe for insertion into the patient. A needle guide may be similarly releasably connected with the probe and, at least in part, inserted into the patient.

Abstract: For alert assistance for an ultrasound scanner, computer-assisted detection is applied as the patient is scanned. The user may be notified of any detected objects so that the user gathers more information when appropriate. An automated system may be configured to return to scan any detected objects. Information is gathered as part of the work flow for that given examination of the patient based on the detection. A mechanical property of the object is derived from the extra information, resulting in further information that may be used to avoid a return visit and/or increase sensitivity in survey mode scans.

Abstract: An ultrasound imaging standoff has a stiffer portion for contact with a volume transducer and a flexible portion filled with viscous fluid for conforming to the patient, resulting in fewer or no air gaps. Pressure is applied through the standoff to cause the connective tissue to flatten, resulting in less shadowing artifact.

Abstract: Separate renderings are performed for data of a same medical imaging mode. The data is processed differently prior to rendering and/or rendered differently to enhance desired image information. For example, a same set of ultrasound B-mode data is rendered with opacity rendering and with maximum intensity projection or surface rendering. The surface or maximum intensity projection highlights strong transitions associated with bones. The opacity rendering maintains tissue information. Different sets of B-mode data may be separately rendered, such as one set processed to emphasize contrast agent response and another set processed to emphasize tissue. The separate renderings are aligned and combined. The combined rendering is output as an image.

Abstract: Raw data reprocessing is provided for ultrasound imaging systems. Clip storing and review functions are more versatile by storing ultrasound data with phase information, such as RF or IQ data. Thorough and ad hoc reanalysis of the acquired data may be performed after the patient has left. The ultrasound imaging system provides the reanalysis without or with export of the ultrasound data. Additionally, a regular PACS system with specially installed software and hardware may also provides the reanalysis with the storing ultrasound data with phase information.
