RaySafe Solo User Manual – Introduction

THE RAYSAFE SOLO
The RaySafe Solo is intended for measurements in medical X-ray imaging applications. The RaySafe Solo is not
intended for use during patient examination.
The RaySafe Solo consists of a base unit and a detector.
Communication between detector and base unit is purely digital, thereby minimizing sensitivity to mechanical
or electrical stress.
THE RAYSAFE SOLO DETECTOR OPTIONS
• The R/F detector has two sensors: R/F high is designed for conventional, high dose rate measurements.
R/F low is designed for low dose rate measurements. The RaySafe Solo R/F base unit can be equipped with
mA/mAs capabilities.
• The MAM detector is used for both low and high dose rates generated in mammography applications.
• The MAM dose detector is a Solo MAM detector, but measures only dose, dose rate and time.
• The Dose detector is an R/F detector, but measures only dose, dose rate, time and pulses.
• The RAD detector is designed for conventional, high dose rate measurements normally generated without a
phantom between the detector and the X-ray source.
• The CT detector is an ionization chamber, designed to measure CT dose for applications such as Dose
Length Product (DLP) and Computed Tomography Dose Index (CTDI).
• The DENT detector is designed for measurements on intraoral dental X-ray machines, OPG and Cone beam.
• The light detector is designed to measure luminance on LCD and CRT monitors, as well as light boxes, and
illuminance for diagnostic X-ray applications.
• There is also a RaySafe Solo mAs model for measuring mA/mAs, time and pulses.

EASY TO USE
The RaySafe Solo is very easy to use.
The built-in active compensation automatically applies corrections for dierent beam qualities, filtrations and
temperatures. During fluoroscopy measurements the displayed values are continuously updated.
If your instrument is equipped with the RaySafe Solo PC kit, data is sent on the serial port to your computer,
where RaySafe Xi View shows numerical data as well as waveforms.

GETTING STARTED
1. Connect the detector to the base unit with one of the two (2 and 10m) cables.
2. Position as required for the detector, see the following chapters.
3. Turn on the RaySafe Solo (ON/OFF key, see below), and the instrument specific setup information is
displayed. In the SENSOR MENU a detector or sensor field for your application can be selected.
4. The instrument is now in MEASURE MODE and ready to measure. Press STEP to scroll through measured
parameters (also possible during fluoroscopy). The last three displayed parameters will automatically show
up after the next exposure. To change setup values (SETUP MENU) such as various delays, displayed units
and other choices, press SELECT.
KEYS ON THE RAYSAFE SOLO BASE UNIT
ON/OFF: Turns on the RaySafe Solo and o when in SENSOR MENU.
EXIT: Exit to the previous menu.
STEP: A short press steps through available options.
SELECT: A long press selects an option.

BATTERY AND CHARGER
The RaySafe Solo base unit has a chargeable 7.4 V Li-ion battery, providing approximately 20 – 40 hours of
operation (depending on selected detector and whether Bluetooth is used). Since chargeable batteries have a
self discharge current, RaySafe strongly recommends fully charging the battery before first use. Battery level is
displayed, together with setup information, when the instrument is switched on.
There are two battery warning levels:
• First warning level, “Battery low”: Finish your measurements and then charge the battery.
• Second warning level, “Battery down”: No further measurements are recommended.
The provided battery charger may be connected during measurement. When connected, the external power
indicator is lit and Charging battery will be briefly displayed.
The battery will be charged even if the instrument is turned o. The charge time from empty to full is
approximately 4 hours.

R/F MEASUREMENT
Using R/F, RAD, Dose or DENT version.
For best accuracy, center the selected sensor field (R/F low, R/F high, RAD, DENT low or DENT high) and
position the long axis of the sensor field perpendicular to the anode-cathode axis of the tube.
1. SENSOR MENU
R/F low
(R/F and Dose)
Sensor for conventional low dose rate measurements < 1 mGy/s
(7 R/min), normally after a phantom.
R/F high
(R/F and Dose)
Sensor for conventional high dose rate measurements > 1 mGy/s
(7 R/min), normally before a phantom.
RAD Sensor for conventional high dose rate measurements > 0.1 mGy/s
(0.7 R/min), normally before a phantom.
DENT low Sensor for low dose rate measurements < 1 mGy/s
(7 R/min), normally after a phantom or for applications with high
(> 10 mm Al or equivalent) inherent filtration.
DENT high Sensor for high dose rate measurements > 1 mGy/s
(7 R/min), normally before a phantom.
Press STEP to step between sensors and SELECT to select a sensor.
