RaySafe i3 Installation & service manual – About the RaySafe i3 System
ABOUT THE RAYSAFE i3 SYSTEM
RaySafe i3 is designed for personal use on hospital sta. It measures scattered radiation in examination rooms using a
dosimeter, and shows a graphical visualization of dose rate in real time on a display.

6: Real-time Hub, 7: Dose Manager software, 8: Dose Viewer software.
The dosimeters measure radiation and store measurements. When a dosimeter is in range of a Real-time Hub,
it automatically connects to the hub via radio. When a dosimeter is connected via radio to a Real-time Hub,
measurements are transferred once per second and are displayed as dose rate bars, low to high dose rate: green,
yellow or red.
All measurements recorded while connected to a Real-time Hub are saved in the hub and can be exported later in
dierent formats.
To view the measurements stored in a dosimeter, connect the dosimeter to a computer running Dose Viewer. Dose
Viewer can also be used for changing dosimeter settings, such as displayed name and annual dose limit.
Dose Manager is an optional analysis software.
RAYSAFE i3 IN A SIEMENS LAB
For installations in a Siemens lab:
• The reference dosimeter and the reference dosimeter holder shall not be used.
• When configuring the Real-time Hub, leave the field for reference dosimeter serial number blank.
NOTE: When no reference dosimeter is present in the system, there will be no history dose rate bars at the
right side of the screen.

RaySafe i3 Installation & service manual – Installation
MOUNT THE REFERENCE DOSIMETER
The reference dosimeter is used to determine when the X-ray tube is emitting X-rays and when it is not. This
information is required to show the history bars on the right-hand side of the Real-time view. It is also needed for the
data export to correctly report when a dosimeter does not receive any dose, even when there is radiation reported by
the reference dosimeter.
If no NTP server is configured, the reference dosimeter is used as time source for the saved data. The dose detected
by the reference dosimeter is also saved and can be used for normalization when comparing procedures, labs and
operators.
The reference dosimeter shall be placed on the C-arm, in the vicinity of the X-ray tube. The exact positioning is not
crucial, see Figure 8 on page 17. The reference dosimeter may be covered with a sterile sheet or plastic bag. The
function and performance will be unaected.
The reference dosimeter holder comes with adhesive Velcro strips.
1. Put the reference dosimeter in the holder.
2. Remove the protection tabs from the Velcro and press the reference dosimeter holder in place, with the dots
towards the radiation source.
Figure 8. Reference dosimeter positioning.
TIP! If the holder does not stay in place, for example on uneven surfaces, try adding another layer of
Velcro where suitable, to fill gaps and add stability.
