  • Patent number: 10314511
    Abstract: A method is provided for identifying a muscle abnormality. The method may include acquiring image data associated with a plurality of muscles in an area of interest of a living subject and generating a data model for the plurality of muscles based on the image data. The method further includes calculating the volume and/or length of one of the plurality of muscles based on the data model, and determining if the volume and/or length for the muscle, as calculated, deviates from volume and/or length associated with a healthy muscle. If it is determined that the volume and/or length for the muscle deviates from the volume and/or length associated with a healthy muscle, a muscle abnormality can be identified based on the deviation.

  • Patent number: 10299760
    Abstract: An ultrasonic diagnostic imaging system is operated to acquire an ultrasound image of a region of the body containing suspect anatomy such as a suspected lesion. A body marker template of the region of the body is displayed on a touchscreen display of the imaging system. The operator records the location of the suspect anatomy by touching a corresponding point on the body marker template displayed on the touchscreen display. The mark on the template can be finely adjusted by one or more controls on the imaging system control panel. The body marker template can also record a graphic indicating the orientation of the ultrasound probe relative to the body when the suspect anatomy was imaged. A report generator produces a report containing both the ultrasound image of the suspect anatomy and the body marker template with the indicated location of the suspect anatomy.

  • Patent number: 10267884
    Abstract: A method is disclosed for creating a motion correction for PET data acquired by a PET system from a volume segment of an examination object. The method includes acquisition of MR data within the volume segment by the magnetic resonance system; and determination of a motion model of a motion within the volume segment as a function of the MR data. The motion model, as a function of a respective motion state of the motion, provides a correction specification for PET data which is acquired during this motion state. During acquisition of the MR data, specific MR data is acquired in the center of the k-space or of a straight-line segment which passes through the center of the k-space. The MR data determined is converted by a mathematical function into one value, as a function of which the respective motion state is determined.

  • Patent number: 10154831
    Abstract: A method for creating a transmural lesion in tissue includes positioning a distal portion of a catheter near the tissue, where an ultrasound transducer is attached to the distal portion and is operatively coupled to a console and processor. The tissue is imaged by energizing the ultrasound transducer at a first power level to produce an ultrasound beam, where the imaging determines a thickness of the tissue, and a gap distance between the ultrasound transducer and the tissue. The tissue is ablated by energizing the ultrasound transducer at a second power level to produce the ultrasound beam. Energy delivered to the tissue during the ablating is controlled, using the processor, where the processor adjusts a speed of the ultrasound beam moving across the tissue based on the thickness and gap distance, to create the transmural lesion.

  • Patent number: 10149650
    Abstract: A method differentiates a blood vessel from a nonvascular tissue during a minimally invasive surgery using a device. A device may be any penetration sensor device, such as a dilator sensor device, a hollow needle sensor device, or a trocar sensor device, which penetrates the skin and subcutaneous layers to reach a target location inside the body. The penetration sensor device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the penetration sensor device can be determined while the device travels towards the target location for surgery.
