Setting Up Device For Procedure

Please read and follow the below instructions to prepare the device before performing a dynamic ultrasound guided procedure with Vscan Air.


Step Name



Configure app settings

  • If working with a display device for the first time, use an example image to adjust the brightness level for optimal visualization of the image based on the ambient environment where the procedure is expected to be performed. Consider dimming ambient lights for better image visualization, wherever possible.
  • Adjust/maximize the Auto-freeze time to avoid image freeze during the procedure due to no user interface interactions. Note that this setting minimizes device heating and battery drainage when device is not being used by freezing the image.
  • Centreline marker can be turned on from the Menu -> Configuration, if desired. Please note that Vscan Air supports only free hand biopsy and needle procedures so the centreline marking should not be confused with biopsy guidelines indicating needle path on the image.
  • The probe button can be configured for additional functionality (Store or Freeze) that could be helpful during procedure to minimize interaction with the display device. It can be configured from the Menu -> Configuration. Accidental long press (3 secs or more) of this button during scanning can lead to unintentional shut down of the probe.
  • The video duration should be set to save cine clips of a length appropriate for documentation requirements.


Use a cool probe

Make sure the probe is sufficiently cooled down after any previous scanning. Disruption may occur due to the probe getting warm if a lengthy procedure is anticipated.

Leaving the probe on a desk (outside the pocket or the case) after it off will help cooling down faster. It should take about 30- 60 minutes to get to a reasonably cool state depending on how warm it was from the previous scan and the ambient temperature. If accelerated cooling of the probe is required, place the probe, while turned off, in front of a fan, run under cold water, or apply cooling pack.


Minimize lost connection between probe and mobile device during scan

The probe without a cable can be very helpful to support sterile procedures. At the same time its use depends on bandwidth and stability of the wireless connection between probe and mobile device.

Following are the recommendations for minimizing loss of real time images due to connection instability:

  1. The probe and mobile device should be within 1 m to each other during pairing, and less than 1.5 meters while in use.
  1. Avoid congested Wi-Fi network environments, if possible.
  1. In cases where multiple Vscan Air probes and display devices with the app are available, make sure
    • the app is closed on all other devices except the one to be used and all other probes are turned off and moved away from the vicinity of the device.


Check battery levels of probe and display device

Ensure that the probe and display device have enough charge before starting a procedure. Charge levels of 50% and above are recommended before starting, and above 30% during procedure. Battery levels of the probe can be checked on the top left corner of imaging screen after connecting with the app.

Please refer to the user manual for the detailed description of the battery level indicator bars.


Confirm ‘Wireless connection quality’ and ‘Probe temperature’

Ensure that the connection between the probe and app is stable by checking the connection quality indicator on the top left corner of the imaging screen.

The probe temperature indicator is also visible in the same place for confirming the use of a cool probe.


Select appropriate preset

Choose the correct preset based on the anatomy being visualized and the planned procedure. Details of the presets and the optimized anatomy are available in the user manual.


Image crop-guidance / Choose display device orientation

Image size is maximized in the portrait mode. As a result, at certain depths, image corresponding to the entire transducer width may not visible on the screen. Image crop indicators are displayed on the sides in such cases. It is recommended to rotate the display device to landscape orientation for visualizing the whole image including the edges and needle entry point.


  1. The image can also be zoomed to pan it sidewise if portrait mode is preferred. OR
  2. The depth increased until the crop indicators on the side of the image disappear indicating that the edges are visible in the field of view.
Refer ‘Image crop indicator’ for a more detailed description.


Position display device

Position the display device in such way that it is comfortable to visualize the image during the procedure (for e.g. Imaging features such as orientation marker is clearly visible, ambient lighting is optimal, display device is in the line of sight and no straining is required). Consider using a cart or stand to mount the display.
