Probe

What are the frequency/depth ranges?​

  • Curved - 2 - 5 MHz with center frequency of 3.3 MHz
  • Linear - 3 - 12 MHz with center frequency of 7.7 MHz
  • Smallest depth on linear – 2cm

What do the arrows indicate?​

Arrows on B-mode enable selection between Resolution (default) and Penetration settings on selected presets. Penetration settings help optimize the image for scanning large or difficult to scan patients.

In color flow mode, the arrows help toggling between fast and slow flow settings by changing the velocity scale (PRF) to a high or low value respectively.

More details can be found under Resolution/Penetration settings and Fast and slow flow settings under the ‘Scanning’ section of the user manual.

What does a yellow wireless connection mean?​

The yellow symbol on the wireless connection quality indicator indicates an unstable or weak connection between the probe and app. This could be due to low bandwidth or a congested network environment. If it persists to be yellow, it may result in sub-optimal image quality, slow update of real time image or dropped frames while scanning.

Does the probe heat up when scanning?​

The miniaturization of devices with beam-forming technology within the probe results in heat production during scanning.

The Vscan Air probe has smart thermal management that makes small changes during long scans to optimize power consumption with minimal impact to imaging performance to enable continuous scanning for 50 minutes. It is recommended to freeze the image when not actively scanning and minimize time in color flow mode to keep the probe temperatures low.

Refer to the User Manual - ‘Thermal management’ for more details.

How long can I scan?​

Vscan Air supports 50 mins continuous scan time (with new and fully charged battery, using 80% grey scale and 20% color doppler imaging at 22oC room temperature). The approximate number of 5-minute exams that can be expected per battery charge are:

  • 7-10 on the curved array presets
  • 8-13 on the linear array presets

The battery lifetime is “at least 500 charges”. What happens after 500 charges?​

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.

The user must expect that when the battery capacity falls below 80% of original capacity. Accordingly, total scan time will be reduced.

As the battery capacity falls, users should consider replacing it.

What function does the “grey button” on curved transducer side have?​

It is actually a sealed door, and it serves no use for users. Attempting to open this could affect the probe’s IP67 waterproof rating.

Behind this door, there is a USB-C connector which is required for probe tests during the manufacturing process. After these tests are performed, the door is sealed and can no longer be opened.

Are probe covers available?​

Vscan Air probe has been verified for use with generic, commercially available probe sheaths and covers. Probe covers should be used where there is a need to maintain a sterile field or infection is a concern. Instructions on how to use the probe with a sheath can be found in the User Manual - ‘Cleaning and Disinfection’.

Can I scan without internet connection?​

Data transmission between app and probe is based on Wi-Fi (Wi-Fi Direct for Android, Access Point for iOS). Bluetooth is facilitating the original identification and pairing. However, you do not need an internet connection to use Vscan Air.

Is internet required for registration?​

You must be connected to the Internet during the probe activation and registration of the App but not for regular use of Vscan Air.

Are there probe to app connectivity options?​

There are currently no user-configurable connectivity options.

How can I manage multiple apps and probes at a hospital?​

At this time, individual mobile devices and probes need to be independently set up and managed.

What does “Your Institution’s mobile device manager controls the content on your device?​

The Vscan Air app can be deployed on devices controlled by a Mobile Device Manager (MDM). MDMs are typically used by organizations to manage mobile devices that have access to the institution's data or systems.

Your organization’s firewall or Mobile Device Manager (MDM) might be blocking access to the GE Healthcare servers, which is required for signing in. Please request to whitelist the following URLs:
