Large ACR MRI Phantom JM Specialty Parts

  • Images to be analyzed by RIT Radia Diagnostic Software ("Automatic scoring software")

    • Description

    The Large MRI QA Phantom is suitable for scanners capable of all examinations,no matter how many modules are on your application. The Small MRI Phantom is suitable for scanners only capable of extremity exams.

    The RIT Radia Diagnostic software automatically analyze MR Images of the above phantoms in seconds. Providing reports on Localizer line length, geometric accuracy, resolution, slice thickness, slice position accuracy, Percent integral uniformity (with full statistics), Percent signal ghosting (with full statistics), Low contrast objects detected with contrast-to-noise reported for each object.
