Evaluation: Butterfly Network iQ Wired Handheld Ultrasound Probe

August 13, 2020 | Evaluations & Guidance


  • The primary purpose of the Butterfly iQ probe is to obtain ultrasound data to aid diagnoses, though the probe can also be used to provide ultrasound guidance during interventional procedures, such as therapeutic injections and fluid drainage. The probe communicates via a cable with the user's (or facility's) personal electronic device (PED), such as a smartphone or tablet computer. When the PED is equipped with the Butterfly Network software application, it can be used to display the image and serve as the user interface.
  • The Butterfly iQ is indicated for imaging of adult and pediatric patients for the following clinical applications: abdominal, cardiac, fetal/obstetric, gynecological, musculoskeletal (conventional and superficial), ophthalmic, peripheral vessel (including carotid, deep vein thrombosis, and arterial studies), procedural guidance, small organ (including thyroid, scrotum, and breast), and urology.
  • Features of the Butterfly iQ probe:
    • Dimensions (L × W × D): 18.5 × 5.6 × 3.5 cm (7.2 × 2.2 × 1.4 in); weight: 313 g (11 oz)
    • The probe supports the following modes:
      • B-mode and combined B-mode/M-mode
      • Color Doppler imaging (CDI)
      • Power Doppler imaging (PDI)
      • Pulsed-wave (PW) Doppler with spectral analysis (supported only in some exam presets). Duplex Doppler is not supported.
    • In addition, the probe has:
      • A transducer that transmits 1 MHz to 10 MHz ultrasound based on the selected exam preset
      • An image-orientation indicator on one end of the probe, with a corresponding orientation indicator on one side of the image
      • A hardwired cable used to connect the probe to the PED. The probe is available with a USB-C or Lightning connector.
      • An LED display to indicate the battery status, and when the battery is charging
      • A button to check the battery status. The same button can be used to store a still image.
  • Features of the Butterfly Network software application: a) The user installs the app on a PED, which can then be used to display acquired data and to allow the user to select imaging presets, enter patient data, optimize images, perform measurements, and export data.
