    Jul 8th, 2026 / MRI QA Essentials for Diagnostic and RT

    Learn more about MRI QA and how to complete your tool kit for both diagnostic and radiation therapy department. Join Tomasz Kostecki, Medical Physicist from Diagnomatic and Umar Baharom, Product Manager and OEM Strategic Accounts from Standard Imaging for a look at our MRI QA phantoms. This session focuses on why precise and reliable image quality QA matters — and how two leading phantoms deliver that confidence.

    • Pro MRI ACR Phantom — An ACR-Approved for comprehensive evaluation of critical imaging parameters of MRI use for the measurement of absolute values for calibration purposes and optimized for efficient daily QA.
    • MR Grid Phantom — A distortion‑mapping phantom built for large bore MRgRT and MR sim QA, giving teams precise insight into geometric accuracy for more confident targeting and treatment planning.
