RaySafe i2 Personal Dosimetry Radiation Monitoring System

RaySafe i2 – Real-time Dosimetry Insight

Approximately 3.6 billion x-ray examinations are performed worldwide each year1, leading to earlier and more accurate diagnosis of medical diseases. However, clinical staff and patients face significant risks of stochastic and deterministic impacts of radiation2. Authorized regulatory bodies emphasize the importance of keeping the dose to medical staff and patients as low as reasonably achievable (ALARA).

Minimizing exposure and achieving the ALARA standard

The traditional method to provide radiation safety is by offering radiation protection training. The medical staff that works in this very dynamic environment easily overlooks the invisible radiation risk. This can often lead to higher than necessary radiation exposure.

The RaySafe i2 allows staff to visualize x-ray in real-time. Building a strong radiation safety culture starts with giving the medical staff real-time insight about their personal exposure. This enables and empowers physicians, nurses, and staff to more effectively use all the radiation reduction solutions provided in the room. The RaySafe i2 is an active dosimetry system that provides real-time insights about radiation exposure, helping medical staff and physicians evaluate and directly adjust their behaviors.

Ease of use

The RaySafe i2 offers ease of use along with quick setup and installation. Similar to many personal electronics, the RaySafe i2 dosimetry system offers touchscreen technology. Personnel wear digitally assigned dosimeter badges and go about performing daily duties without interruption. Dose data is measured and saved for post procedure review and analysis.

Low maintenance

The RaySafe i2 system stores data for up to 5 years, making this system your long term partner in building a first-class radiation safety culture. The dosimeter lasts 3-5 years, dependent on use, and does not require any annual calibration or maintenance. The system is built for rugged use in interventional and vascular labs.

RaySafe i2 real-time display

The RaySafe i2 real-time display is a 10.4" touch screen which is placed in the examination room. It shows real-time dose data from all dosimeters in range. The color indication (red, yellow, green) gives the individual user insight about the current dose exposure and the possibility to act accordingly. The accumulated dose per individual user is displayed next to the color indication bars.

RaySafe i2 real-time display features

    By tapping the dosimeter name on the touch screen you can access more detailed information about the personal dose history:
  • A dose dashboard with total dose history and trip meters
  • Annual personal dose and dose in relation to a configurable yearly limit
  • Detailed views presenting time stamped dose history

RaySafe i2 dosimeter

The active dosimeter measures and records radiation every second. Dose data is transferred wirelessly to the real-time display. The dosimeter is maintenance-free, easy-to-use and can be personalized with different names and colors.

RaySafe i2 dose viewer

The dose viewer software helps administrating dosimeters and viewing personal dose information while connected to the RaySafe i2 cradle.The software allows you to view dose data history, change dosimeter names and reset dose history.

RaySafe i2 dose manager

The RaySafe i2 dose manager is an advanced software for analyzing, reporting and archiving dose information. The software handles multiple dosimeters and can retrieve dose information from multiple real-time displays through the hospital network or via USB storage.
