ABOUT THIS USER MANUAL

This user manual is intended to assist users in the safe and eective operation of the product described.

Before attempting to operate the product, you must read these instructions for use, noting and strictly

observing all WARNINGS and CAUTION notices.

WARNING A WARNING alerts you to a potential serious outcome, adverse event or safety hazard. Failure

to observe a warning may result in death or serious injury to the operator or patient.

CAUTION A CAUTION alerts you to where special care is necessary for the safe and eective use of

the product. Failure to observe a caution may result in minor or moderate personal injury or

damage to the product or other property, and possibly in a remote risk of more serious injury,

and/or cause environmental pollution.

NOTE Notes highlight unusual points as an aid to an operator.

These Instructions for Use describe the most extensive conﬁguration of the product, with the maximum number

of options and accessories. Not every function described may be available on your product.

RaySafe Xi User Manual – Introduction

THE RAYSAFE Xi

The RaySafe Xi is intended for measurements in medical X-ray imaging applications. The RaySafe Xi is not

intended for use during patient examination.

The RaySafe Xi consists of a base unit and several dierent external detectors measuring: Radiography/

Fluoroscopy (R/F), mammography (MAM), on AEC or ABC systems (Transparent), Computed Tomography (CT),

ambient and emitted light (Light) and scattered or low level radiation (Survey).

Communication between detector and base unit is purely digital, thereby minimizing sensitivity to mechanical

or electrical stress. The base unit may also be equipped with an optional integrated tube current meter

(mA/mAs).

THE RAYSAFE Xi DETECTORS

• The R/F detector has two sensors: R/F high is designed for conventional, high dose rate measurements

normally generated without a phantom between the detector and the X-ray source. R/F low is designed for low

dose rate measurements normally generated with a phantom between the detector and the X-ray source.

• The mammography sensor is used for both low and high dose rates generated in mammography

applications.

• The transparent detector is a solid-state detector with a very small radiologically visible footprint. It is

intended to be used for applications where the R/F detector would inﬂuence the automatic exposure

control on X-ray equipment and serves as a complement to the R/F detector. The transparent detector is

designed to mimic the response of a pancake ion chamber detector and therefore it has no backscatter

protection.

• 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 light detector is designed to measure luminance on LCD and CRT monitors, as well as light boxes, and

illuminance for diagnostic X-ray applications.

• The survey detector is designed for measuring leakage or scattered radiation from X-ray tubes or in

examination rooms and leakage radiation from γ-emitting isotopes.

THE RAYSAFE Xi BASE UNIT

There are two versions of the RaySafe Xi base unit: one with and one without mA/mAs capabilities. Both

versions are fully compatible and interchangeable with the RaySafe Xi detectors as long as the ﬁrmware

supports the detector (see Speciﬁcations). In this manual all information refers to both versions unless

otherwise speciﬁed.

The RaySafe Xi base unit automatically identiﬁes the connected detector and displays the settings and

parameters available for that detector.

The built-in active compensation automatically applies corrections for dierent beam qualities, ﬁltrations

and temperatures. During ﬂuoroscopy, survey or light measurements the displayed values are continuously

updated. Data is sent on the serial port, and RaySafe Xi view, the program included with your RaySafe Xi, shows

numerical data as well as waveforms on a PC.

RaySafe Xi User Manual – The RaySafe Xi

GETTING STARTED

1. Connect a RaySafe Xi detector of your choice to the RaySafe Xi base unit with one of the two (2 and 10 m)

RaySafe Xi cables.

2. Position as required for the selected sensor.

3. Turn on the RaySafe Xi (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 RaySafe Xi 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 Xi BASE UNIT

ON/OFF: Turns on the RaySafe Xi 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.

TRANSFER DATA TO A COMPUTER

To view the waveform in the RaySafe Xi view and/or transfer measured data to a PC, connect a serial cable or

Bluetooth module (option) to the communication port on the RaySafe Xi base unit.

BATTERY AND CHARGER

CAUTION! Only authorized personnel may remove and replace the battery.

Fully charge the battery with the provided battery charger before ﬁrst use. Battery status in percentage is

displayed, together with setup information, when the instrument is switched on.

RaySafe Xi/Unfors Xi Platinum Plus Unfors Xi Platinum

FOR RAYSAFE Xi

The provided battery charger may be connected during all measurements.

FOR UNFORS XiPLATINUM

The provided battery charger may be connected during measurement except when measuring mAs, as it may

create ground currents aecting the measurement. However, the RaySafe Xi battery charger may be connected

during all measurements.

Xi version Battery type Hours of operation Charge time

RaySafe Xi 7.4 V Li-ion 20–40 hours 4 hours

Unfors Xi Platinum 9 V NiMH 10–20 hours 15 hours

RaySafe Xi User Manual – Getting Started

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 possible.

When the provided battery charger is connected, the external power indicator is lit and Charging battery will

be brieﬂy displayed. The RaySafeXi battery will be charged even if the RaySafe Xi is turned o.

There is a battery charger LED indicator that is indicating red while charging and green when the battery is fully

charged.
