Display Device

Is there a Resolution Difference?​

To obtain the best image quality visualization it is recommended to use devices with a minimum screen resolution of 960 x 640 (or 640 x 960) pixels. Prior to scanning for the first time, the display brightness should be adjusted using the display calibration scale from the ‘Menu’ to visualize the complete grey scale range.

It is recommended to turn off adaptive brightness, color filters etc. that could impact the visualization. Refer to the User Manual - ‘Display device image quality verification’ for more details.

Do Batteries Drain Faster?​

Yes. While scanning, the Vscan Air app is using the computational resources of the mobile device to process images and the Wi-Fi module to communicate with the probe, which will affect the battery level of your mobile device. It is similar to when you stream video on your mobile device.

Will Phone/Tablet Software Updates Impact the Performance of a Vscan Air?​

We strive to qualify mobile devices with latest operating system versions and manufacturer releases. To ensure you mobile device performs as expected with Vscan Air, we suggest disabling automatic updating of new operating systems and software, and delay upgrading until the new software has been verified for compatibility. Support of new OS versions and more, will be published.

How will I be notified of app updates? Will I need to buy a new probe?​

New updates will be available via the respective App store. If you have enabled notifications from the App store, you will be notified when new updates are available. Some mobile devices also allow auto-upgrade of apps.

Probe firmware updates are delivered via the Vscan Air app itself. If a firmware update is available, it will be updated when the probe is connected to the App.

Can Vscan Connect to Windows Devices?​

As Vscan Air is running on a mobile device, its screen can be displayed anywhere your mobile device is able to connect and screen share, such as Apple TV, Chromecast, Android/iOS Screen share, Miracast, etc. However, no screen sharing methods are validated by GE Healthcare and the images displayed in this manner may not be equivalent to the image on the mobile device. As such they should not be used for diagnostic purposes.

Is it possible to Screenshot a Vscan Air?​

If your mobile device can take screenshots, then it is possible to take screenshots of the Vscan Air app. However, note that a clinical image will contain any patient data that is visible on the screen.

To share images without patient data, consider using the Share (with other apps) feature within the app. This shares anonymized images with other apps on your mobile device, such as text, email, and social media.

To share images for collaboration with patient data, use DICOM® or Shared Folders that are set-up for your institution.

Where are the images saved on the app?​

Patient data and images are encrypted and stored separately from other apps, ensuring patient data cannot be shared with other apps (in compliance with U.S. government’s Federal Information Processing Standard (140-2) for encryption of sensitive data). The Vscan Air app cannot access other information on the mobile device and only anonymized images can be shared with other apps.

How many devices can I use with my probe?​

You can pair the Vscan Air probe with any number of display devices at this time. However, you can only pair to one display device at a time while scanning or reviewing images with any given probe.

How much hard drive space do the images take?​

  • A still image is around 200-500 kB in size and a one second loop, 2-5 MB
  • 1 GB: Minimum 200 videos (1 second loops)
  • 1 GB: Minimum 2000 images

How should I disinfect/clean my personal mobile device?​

Mobile devices should be cleaned and disinfected according to their manufacturer’s recommendations and your institutional protocols.

Manufacturers frequently update information on their websites regarding compatibility with common cleaning and disinfection agents. For example: https://support.apple.com/en-us/HT204172.

Medical grade display devices often support a wider range of cleaners and disinfectants compared to display devices for the consumer market. Protective covers may be used where a sterile field needs to be maintained or infection is a concern.
