QUASAR™ GRID³ᴰ Image Distortion Analysis System


The QUASAR™ GRID³ᴰ Image Distortion Analysis System is designed to evaluate MR and CT imaging data on Leksell Gamma Knife® platforms, including PERFEXION™ and ICON™.

Understanding the integrity of your system’s spatial accuracy provides you the confidence of accurate and precise delivery of Gamma Knife stereotactic radiosurgery. Use the valuable data obtained using GRID³ᴰ to optimize imaging sequences and manage image distortion on your planning systems.


Compatibilty: Process images and assess distortion on MR and CT systems with or without a Leksell Gamma Knife® fiducial box. Ability to process co-registered datasets with increased support for ICON™ CBCT analysis. Valuable for Geometric Distortion Analysis on all Leksell Gamma Knife® platforms.

High Resolution Accuracy: Dense 1 cm3 matrix of 1.5 mm signal generating channels create 2002 control points for geometric distortion analysis. 

Increased Confidence: Option to assess Geometric Distortion within an imported GammaPlan™ spatial reference frame.

Workflow Efficiency: Automated image analysis with advanced interface, visualization and reporting features.
