Devices and methods for vascular navigation, assessment and/or diagnosis are disclosed where a location detection system generally includes an elongate body defining a lumen at least partially along a length of the elongate body. One or more sensors are positioned near or at a distal tip of the elongate body and one or more openings are defined along the elongate body in proximity to the one or more sensors. The one or more openings are configured to control a boundary distance between the one or more sensors and a fluid with a parameter of a known initial value when emitted from the one or more openings. A controller is in communication with the one or more sensors and is configured to track a change in the parameter relating to concentration over the one or more sensors and determine a position of the one or more sensors within a body.

Disclosed are systems and methods using ultrasound to predict if a patient's cardiac stroke volume will increase with a fluid bolus. Ultrasound measures are taken before administering a fluid bolus, including measurement of the left ventricular outflow tract velocity time integral (LVOT VTI), and venous measurements of the internal jugular vein. Data collected from such ultrasound scan is then used to predict the patient's cardiac volume response in the event that a fluid bolus is administered to that patient.

An ultrasound diagnostic apparatus (1), which performs a compression test with respect to at least two points of a popliteal vein and a common femoral vein of a subject, includes an ultrasound probe (15), an image acquisition unit (8) that acquires an ultrasound image by transmitting an ultrasound beam toward the subject from the ultrasound probe (15), a vein detection unit (9) that detects the popliteal vein included in the ultrasound image, and an operation guiding unit (10) that guides a user, in a case where the compression test of the popliteal vein is performed, to operate the ultrasound probe such that the ultrasound probe (15) is positioned at a position in which only one popliteal vein is included in the ultrasound image based on the number of the popliteal veins detected by the vein detection unit (9).

To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and an output data module may be used to move data for all received channels off-chip as a digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. The on-chip digitization of received signals also enables the on-chip integration of ultrasound processing and/or pre-processing to reduce the burden on off-chip computing. Data compression architectures are disclosed to facilitate the transfer of data off-chip as a digital data stream in accordance with the bandwidth requirements of standard commercially-available output interfaces.

Color Doppler imaging with line artifact reduction is provided in multi-beam scanning. Doppler estimates representing the same spatial location but calculated from spatially distinctive transmit beam groups are combined through weighted linear interpolation. Methods of calculating the linear interpolation weights are provided based on geometric relationships and optimization functions. Complete overlapping and superposition among receive beams in the interpolation region are not required. Partial interpolation among the receive beams, where only the estimates of the outer receive scan lines may overlap and be interpolated while estimates for scan lines closer to the transmit scan line are not interpolated, allowing for more rapid frame rate.

An ultrasound imaging apparatus and a control method thereof. The ultrasound imaging apparatus may include: a display; a communication unit; and a processor configured to be operatively connected to the display and the communication unit. The processor may obtain a first ultrasound image of a subject and a result of an analysis of the first ultrasound image. The processor may also control the display to display a user interface, which allows selection of an operating mode of the ultrasound imaging apparatus, based on the result of the analysis.

A system includes an ultrasound probe comprising an ultrasound transducer, a first motor configured to rotate the ultrasound transducer around a horizontal axis to scan a plane, and a second motor configured to rotate the ultrasound transducer around a vertical axis to move to a different plane. The system further includes a controller unit configured to select a number of scan planes for an interlacing scan to scan a volume of an area of interest in a patient's body using the ultrasound probe; select an interlacing factor for the interlacing scan; divide the scan planes into groups of scan planes based on the interlacing factor; and perform the interlacing scan by controlling the first motor and the second motor, wherein the first motor moves in a first direction for at least some of the scan planes and in a second direction for other ones of the scan planes.

A transducer fixation apparatus is configured to position and secure to a skin surface of a patient a transducer to allow repeated or continuous monitoring of blood flow in a subsurface vessel. The transducer fixation apparatus includes a housing having a plurality of flexible attachment wings that attach and conform in shape to the skin surface using an adhesive material present on each of the wing undersides. In some embodiments the wings may be biased upward away from the skin surface to facilitate positioning of the fixation apparatus prior to skin attachment. Alternative embodiments include a detachable retainer clip to hold the wings away from the mounting surface during placement as well as an optional positioning wand to aid with placement. Other embodiments may include a separate flexible attachment wing configured to hold a gel pad for acoustic coupling to the skin surface, the separate flexible attachment wing intended to be joined to the housing of the transducer fixation apparatus prior to skin surface attachment.

A multifunctional probe includes a hand-held housing, a signal detector and an array probe. The signal detector is flexibly disposed on the hand-held housing or at its first end. The array probe is disposed at one end (e.g., second end) of the hand-held housing and electrically coupled to the signal detector. The first contact time of the signal detector in contact with the living body may at least partially overlap with the second contact time of the array probe in contact with the living body. The signal detector and the array probe generate the first electronic signal. The multifunctional probe includes a flexibly-connected signal detector and an array probe, which can contact and/or detect the living body at the same time. Thus, the detection efficiency and accuracy are effectively increased. A detection method applied to the multifunctional probe is also provided.
