LEXXOS, de digitale 2D flash-beam DXA scanner

Digital Flash Beam Technology, a Patented X-Ray Bi-Dimensional Beam

Digital Flat Panel Detector in Amorphous Silicon Detector (A-Si) of 512 x 512 elements (262 144 elements) Pixel is 400 µm

• DEXA cone beam with the Detector located under the table while generator is in the top of the arm

• DEXA without scan for Multisite acquisitions and with X and Y scans for Whole Body acquisitions.

• Motorised Arm – Fixed table

• Innovative Patented Reconstruction Image MEthod (P.R.I.ME.) from the CEA/Leti for Whole Body /F.V.A. scans reconstructions using a continuous shoot cycle (low energy and high energy).

FILTRATION METHOD : Switched and Filtered Beam for an Optimised Image Quality

• Switched X-ray tube delivering two successive X-ray flashes at 70 and 140 KV

• Specific filters addition to ensure an optimised image quality

• Patented anti-scattering grid

PATIENT & PRACTITIONER COMFORT : Expanded Capabilities for a Productivity Breakthrough

•  Whole Body window : 200 x 61 cm using P.R.I.ME.

•  Multisite acquisition : 20 x 20 cm --> no scan required

• Isotropic detector, near to the patient – insignificant magnification

• All operations accessible from the PC

• Repositioning of the patient with the S.E.V. (Single Energy Viewing) capability.

• Arm and Laser positioning controllable via the front panel.

• Caucasian, Asiatic, Arabic, South American, N-Hanes III…

• Possibility, for the operator, to create his own reference database

• Dedicated translation software for text in local language
