GE Discovery LS

The GE Discovery LS is a whole-body 4-slice PET/CT scanner –
the fusion of GE’s PET Advance NXi and LightSpeed Plus CT.
The GE Discovery LS provides perfect registered and
fused anatomical and functional images for optimal treatment planning and followup.
Using GE’s PET Advance NXi functionality, the Discovery assesses the
body’s chemical or physiological changes that often precede anatomical changes visible
in CT or MR. The Advance NXi within the GE Discovery LS ensures the highest 2D and
3D sensitivity, full-field uniformity of resolution and high count rate capability.
A refurbished, used GE Discovery LS is an affordable and very reliable option to
introduce PET/CT imaging and its superior clinical usage into your department or clinic.
