PET/CT acquisitions can last several minutes. In these cases, breath holding is not an option. Consequently, the resulting motion artifacts can significantly distort an image, which can lead to image misinterpretation, misrepresentation of lesion size, apparent reduction of measured SUV, and the overlooking of smaller lesions.  Moreover, motion artifacts may directly impact radiotherapy planning, treatment, and interpretation of treatment response over time.

Motion VUE2 lets you review and analyze PET and CT images acquired on a PET/CT scanner equipped with a respiratory gating system, and following respiratory motion correction.  With it, you can display fused gated PET and CT images, employ a multi-phase cine review tool, fully customize your layouts, and you can quantify uptake activity. Motion Vue2 also helps you understand lesion displacement in both PET and CT gated acquisitions.

Intended Use

MotionVUE2 (Q.freeze) is a PET/CT, non- invasive image analysis software application* designed to support the viewing and manipulation of medical images from PET and CT imaging modalities.

MotionVUE2 (Q.freeze) offers processing tools to optimize workflow of respiratory gated exams for PET, CT and fused images of respiratory gated datasets for simultaneous viewing in multiplanar volumes and cine loops.

MotionVUE2 (Q.freeze) allows the users to generate from their 4D-PET or 4D-PET/CT series a registered 4D-PET series used for quantification of lesions and analysis of functional activity. With MotionVUE2 (Q.freeze), users will have the possibility to compare static PET/CT, 4D-PET/CT, and registered 4DPET series including visual comparison, quantification of lesions, and analysis of functional activity.

MotionVUE2 (Q.freeze) provides registration performance of up to 2mnu of center of mass motion when motion is no larger than the diameter of the object. MotionVUE2 (Q.freeze) provides comparable/equivalent improvement of quantification results (SUV and size) as 4D PET techniques- MotionVUE2 (Q.freeze) can be used for features with locally concentrated activity within the entire Thorax area- This area includes the organs where PET/CT imaging has the most challenges due to respiratory motion: Lung, Liver, Pancreas.
