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 different 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.
