Evaluation: GE Healthcare Vscan Extend with Dual Probe Handheld Ultrasound Scanner

September 13, 2017 | Evaluations & Guidance


  • The Vscan Extend HHUS scanner is intended for POCUS applications.
    • POCUS refers to the use of the technology by the treating physician or other caregiver at the POC, as opposed to sending the patient to an imaging specialist such as a radiologist.
    • HHUS scanners are also used to guide interventional procedures, such as therapeutic injection of medications or diagnostic biopsies.
  • The Vscan Extend consists of the following:

    • A handheld display component that is 168 × 76 × 22 mm (6.1 × 3.0 × 0.9 in) in size and weighs 321 g (11.3 oz). The display component has a serial port used for service, a port to connect the battery charger, a microSD card slot, a USB port, and a battery-status LED indicator. The display component is used to:
      • Enter patient data.
      • View the acquired images on a 127 mm (5.0 in) video display that has 1280 × 720-pixel resolution.
      • Adjust imaging parameters: depth, B-mode gain, and CDI gain.
      • Make measurements. Up to eight distance measurements can be performed on an image. Measurements can be done during patient assessments or on images archived on the device.
      • Archive digital still images and video recordings up to four seconds in duration. The device supports Federal Information Processing Standards (FIPS)-compliant encryption of stored data.
      • Download patient data and DICOM Modality Worklists.
      • Export data wirelessly or via a USB cable for remote consultation, viewing, and archiving.
      • Back up encrypted patient data, store error logs, and upgrade the application software using removable microSD cards.
      • Access security features to create PIN codes to limit use of the device and secure protected health information (PHI).
      • Load Mobile Device Management clients to enable centrally administered device management.
      • Access the Internet to download vendor applications and upload data to cloud storage, as well as to access other Internet applications.
    • A handheld transducer (also called a probe) connects to the display component via a 102 cm (40.5 in) cable.
      • The transducer transmits ultrasound waves into the patient and receives echoes, which are used to create an image on the video display.
      • The Vscan Extend's Dual Probe has a phased-array sector transducer on one end and a flat linear-array transducer on the other end (see the image above). It is 129 × 39 × 28 mm (5.1 × 1.5 × 1.1 in) in size and weighs 120 g (4.2 oz).
      • An LED indicates the active transducer, and on all four sides of each probe there are marks to indicate the center of the ultrasound beam, which are used during ultrasound-guided interventional procedures.
      • The table below lists the clinical application presets for each transducer.
      • You can learn about the types of ultrasound transducers in this Guidance Article.
