Philips Allura Xper FD 20/10 and interventional tools
The Allura Xper FD20/10 is a biplane flat detector
system with integrated 3D for intricate
neurovascular procedures. Combining the proven
stable geometry with 'real-time' Allura
3D- reconstructions,
Xper CT,
SPECTRA BEAM
3D Roadmapping,
and multi-modality information integration,

Xper ctWith XperCT clinicians can access CT-like imaging right on the angio system so that they can assess soft tissue, bone structure and other body structures before, during or after an interventional procedure. The XperCT reconstruction is created from a rotational acquisition performed on the Allura Xper system. This reconstruction can be overlaid with the 3D vascular image.
IT Bring 3D soft tissue imaging to your angio suite
3D soft tissue imaging supports diagnosis, planning, interventions and treatment follow-up, XperCT can be combined with Allura 3D-RA images to visualize soft tissue and vascular anatomy on one image. Using CT-like imaging for a post-procedural check can help reduce delays and improve patient comfort.

The combination of SpectraBeam with the MRC- tube allows The combination of SpectraBeam with the MRC- tube allows increased X-ray output with better filtration of soft radiation. increased X-ray output with better filtration of soft radiation. SpectraBeam offers filters of 200, 500 and 1000 microns SpectraBeam offers filters of 200, 500 and 1000 microns thickness Cu equivalent to provide a high level of radiation thickness Cu equivalent to provide a high level of radiation protection regardless of the projection or patient protection regardless of the projection or patient absorption. This reduces patient X-ray dose for cardiac and absorption. This reduces patient X-ray dose for cardiac and vascular applications, while maintaining the same image vascular applications, while maintaining the same image quality.quality.

X-Ray Tubes

The high performance metal ceramic tubes .Most relevant feature is support of the rotor anode in a spiral groove bearingThe spiral groove bearing glides on a thin film of liquid metal to maximize heat dissipation allowing virtually unlimited X-ray sessions without forced cool down delays.• The MRC tube runs silently offering a more comfortable patient environment.• Another secret of the MRC tube is the enormous heat storage capacity of its 200 mm diameter anode, eliminating waiting times.• And, the MRC X-ray tube can image the heaviest patients even at steep angles, while maintaining image quality.
