Delivery, Report & Follow-Up
We execute the project according to plan, provide comprehensive documentation with clear findings and recommendations, and remain available for follow-up questions or clarifications as needed.
MRI Imaging & MRI Quality Assurance
MRI geometric accuracy and image quality are critical for diagnostic imaging and radiation therapy workflows. SpinTecx specializes in MRI quality assurance programs that support spatial consistency, monitor system performance over time, and support imaging protocol consistency within clinical workflows. Our MRI physics expertise spans diagnostic imaging, MR simulation for radiation therapy, and emerging MRI-guided radiotherapy applications. Delivered by MRI-experienced medical physicists supporting diagnostic imaging and MR-in-RT workflows.
Why MRI QA Matters
Geometric distortion in MRI can compromise diagnostic accuracy and introduce systematic errors in radiation therapy planning. Our comprehensive QA programs quantify distortion characteristics, establish baseline performance metrics, and provide trending analysis to support early identification of performance changes.
MRI QA Program Design
Custom quality assurance schedules aligned with ACR guidelines, routine performance monitoring protocols, acceptance baseline establishment, and tolerance specification development for your specific clinical applications.
Geometric Distortion & Spatial Integrity
Comprehensive distortion evaluation using specialized phantoms, 3D distortion mapping and analysis, gradient linearity assessment, spatial accuracy verification, and stability trending over system lifetime.
MRI Safety & Operations Support
Safety policy review and recommendations, workflow guidance for complex imaging protocols, equipment specification review for new installations, and documentation support for accreditation requirements.
MRI for Radiation Oncology
MR simulation QA program development, imaging protocol optimization for treatment planning, geometric accuracy validation for target delineation, and MRgRT readiness assessment with recommended commissioning checks.
Typical Deliverables: QA protocol documents and measurement templates, baseline performance reports with acceptance criteria, trend analysis dashboards tracking long-term stability, distortion maps and spatial accuracy summaries, and corrective action recommendations with clinical impact assessment.
