MRI test phantom QUASAR™⁴ᴰ

general purpose

Quasar MRI⁴ᴰ is the world’s first MR-safe programmable motion phantom. Adapting for motion in Radiation Therapy requires advanced QA tools and the MRI⁴ᴰ enables you to develop, test and validate advanced 4D treatment delivery protocols on MR-sim and MR-Linacs. Interchangeable inserts are available for imaging, planning, targeting, dosimetry and delivery QA. The included software provides tools to create, import, edit and stream patient-specific respiratory waveforms. Features 100% MR Safe The patented MRI⁴ᴰ design allows phantom placement directly within the MR bore enabling quick, easy and precise operation. Efficient piezoelectric motor assembly allows for high quality, artifact-free imaging up to 3T. MRI⁴ᴰ design preserves image quality by maintaining B0 homogeneity and minimizing magnetic eddy currents within the MR system. Workflow Efficiency Compact, integrated phantom design along with easy-to-use motion software saves time and increases operational efficiency by reducing or eliminating the need for complex or tedious assembly before and after operation. Superior imaging contrast provides easy target detection, which simplifies testing setup while maximizing accuracy. Testing Versatility Fillable components allow complete customization of contrast media, enabling improved visualization of desired structures. Configurable and interchangeable dosimetry inserts increase the functionality of the MRI⁴ᴰ. With the flexibility of choosing motion location and phantom orientation, the MRI⁴ᴰ is able to fulfill a physicist’s most demanding QA needs.
