As a pioneering solution within the Interventional space, Motion FreezeTM can help salvage Cone Beam CT acquisitions by refining and increasing small contrasted structures in Cone Beam CT images that would have otherwise been discarded due to involuntary respiratory motion artifacts .
With a fast post-reconstruction option, streamline procedure workflow with the opportunity to
recover,1 rather than discard, initial Cone Beam CT acquisitions.
No additional dose or contrast media
By potentially reducing the need to repeat Cone Beam CT acquisitions, Motion Freeze may help minimize radiation dose and contrast media injection.
Facilitating Access to Advanced Applications
Severe involuntary respiratory motion artifacts can result in a failure to detect tumor feeding vessels, while using advanced solutions for automated vessel detection7 (such as Liver ASSIST) may result in improved local tumor response.6
By helping to salvage, rather than discard, initial Cone Beam CT images, Motion Freeze enables access to advanced solutions.
1st commercialized solution2 that compensates for involuntary respiratory motion artifacts on lnterventional Cone Beam CT.
39% (1.9 Billion) of the world adult population is overweight (BMI>25) or obese.4 These patients may have more difficulties holding their breath during the intervention. Motion Freeze provides a new option for physicians to use Cone Beam CT that would be affected by involuntary respiratory motion artifacts.
In up to 25%3 of unusable Cone Beam CT images affected by involuntary respiratory motion, Motion Freeze, by potentially reducing the need to repeat Cone Beam CT acquisitions, may help minimize radiation dose and contrast media injection.
Facilitate access to advanced solutions such as Liver ASSIST, delivering results up to:
97% improved sensitivity in identifying tumor feeding vessels;
30% less mean number of DSA;
11 % reduction in procedure time for a single TACE session;5
~68% complete tumor response versus DSA alone (36%).6
Physicians estimate that up to 40%3 of acquisitions are unusable due to involuntary respiratory motion artifacts.
"The difference Motion Freeze provides is impressive – beautiful and clear. In the cases I examined, the Motion Freeze image has an incomparable quality and is usable, while the original acquisition was not."
Professor Thierry De Baere8
Head of Interventional Imaging Department,
Gustave Roussy Cancer Campus
“The results with Motion Freeze are quite impressive in terms of image quality improvement. We improved image quality, making Cone Beam CTs with little motion almost perfect, and improving Cone Beam CTs with a lot of motion so that they became clinically usable in many situations.”

* The improvement related to Motion Freeze depends on the acquisition conditions, table position, patient, type of motion, anatomical location and clinical practice. Motion Freeze is an optional feature of 3DXR (part GE Interventional X-ray systems Innova IGS 5, Innova IGS 6 and Discovery IGS 7 or Discovery IGS 7OR). 3DXR and Motion Freeze may not be available in all markets.
