1 - PCI ASSIST refers to features of Innova IGS 520, Innova IGS 530 and Discovery IGS 730.

2 - Improvement vs. same test without PCI ASSIST option. IQ and visibility improvement is measured on Innova IGS530 with phantoms using various Plexiglas Thicknesses, acquisition parameters and the NEMA spoke wheel tool (ref 1), calculating the ratio of the contrast of the moving wires to the background noise level. The amount of Image Quality improvement related to PCI ASSIST depends on the acquisition parameters, clinical task, patient size, amount of motion in the image, anatomical location, and clinical practice.
