INTRODUCTION
ABOUT THE RAYSAFE i2 SYSTEM
Figure 1. RaySafe i2 System overview
The RaySafe i2 System can contain the following components:
• dosimeter
• real time display
• dose viewer (computer software)
• dose manager (computer software)
• cradle (dock station used to connect dosimeters and computer)
• dosimeter rack (dosimeter storage)

RaySafe i2 dose manager user manual – Introduction
HOW THE SYSTEM WORKS
The dosimeter measures and records X-ray exposure every second and transfers the data wirelessly, via radio,
to the real time display.
The real time display shows real time dose exposure from up to eight dosimeters in range at a time.
Color indication bars (green, yellow, red) represents the intensity of the currently received exposure. The
accumulated dose per individual is displayed next to the color indication bars. By tapping a dosimeter name
the user can look at historical data in separate views.
When the dosimeter is not in use, it should be stored in the dosimeter rack, away from the real time display.
More detailed historical dose information can be transferred from dosimeters via the cradle connected to a
computer and viewed using the computer software (dose viewer and dose manager).
The dose viewer software is also used for administrating dosimeters, change dosimeter names, colors and
reset dose history. The dose manager software is an advanced software for analyzing, reporting and archiving
dose information. It handles multiple dosimeters and can retrieve the dose information from multiple real time
displays through the hospital network or via USB storage.

DOSIMETER OPTIONS
INFORMATION TAB
The Information tab contains information about the person using the dosimeter.
Figure 5. Information tab
Table 4. Information tab functions
FUNCTION DESCRIPTION
Full name Full name of the person using the dosimeter. This text field is limited
to maximum 40 characters due to space limitations in the real time
display.
If dosimeters are shared with others, it may be convenient to name
the dosimeters “Doctor1”, “Doctor2”, and so on, for the clinical role
“Doctor”. Using dierent colors on the dosimeter can also help to
separate each clinical role.
12
RaySafe i2 dose manager user manual – Get to know dose manager
FUNCTION DESCRIPTION
Displayed name The name that is displayed when the dosimeter appears in a real time
display. This name is also used to identify a dosimeter in dose viewer
and dose manager. This text field is limited to maximum 16 characters
due to space limitations in the real time display.
Dosimeter position Reflects where on the person the dosimeter is positioned and can be
set to one of Head, Torso, Hand, Belly, Leg or Other.
Clinical role Reflects the role of the person using the dosimeter and can be set to
one of Doctor, Nurse, Technician or Other.
Displayed symbol The color which is displayed when the dosimeter appears in a real time
display.
Annual dose limit This value is used to show the annual dose value in relation to the
annual dose limit in percent. If you do not want to show this relation,
set this value to 0.
NOTE The annual dose limit for the dosimeter is dependent of the shielding factor of the lead apron,
as well as other radiation protection used. The more protection the higher the limit can be for
the same eective dose to the user. The annual dose limit may or may not be chosen to reflect
the legal dose limit where it is used. It could reflect the legal limit or for example a lower
target for the clinical user case. These and other considerations need to be counted for when
choosing the annual dose limit.

history cannot be retrieved.
• In dose manager, the dose history that was available before reset
will be archived and possible to retrieve by clicking + next to the
dosimeter in the All dosimeters window. Dose manager will start
a new session for the dosimeter and it will appear as if the dose
history will start measuring from 0 in the new session.
