Commissioning, sequence optimization and ongoing QA for radiation oncology and diagnostic MRI, guided by experienced medical physicists.
Start with a focused question or build continuing support around your existing vendor and physics coverage.
MRI physics consulting is available separately from software programs in development.
Agree on selected sequences and deliverables for a paid assessment, then discuss continuing support if useful.
Agree scanner, application, sequences and questions.
Agreed testing plan and compatible phantom measurements.
Documented findings and practical protocol recommendations.
Review repeat measurements, establish a baseline and plan ongoing QA.
Your clinical team retains protocol approval and patient-care decisions.
A tool supporting site-specific MRI assessment and consulting, using GHead and ACR phantom measurements analyzed in SpinTecx software.
Characterize geometric distortion using a controlled head-shaped lattice and air-cavity interfaces.
Assess scanner image quality and evaluate your clinical sequences on a standard phantom.
Bring measurements, maps and comparisons into reports with practical recommendations for qualified physicist review.
Scanning instructions, analysis and physicist review are tailored to the scanner, coils, sequences and setup, with scope and delivery agreed with your team.

GHead phantom

Same-session comparison across 9,789 sampled lattice points, measured against phantom design geometry. Our software measures the effect of the scanner's correction setting.
Preliminary research analysis: one scanner and session, with final physicist review pending. Not clinical acceptance or a validated product-performance claim.
Separate anonymized example; preliminary results.
A research application evaluating volunteer image quality and field-map-derived B0 displacement estimates to investigate sequence tradeoffs alongside the phantom baseline. Research use only. Not for diagnosis or treatment-planning decisions.
Physics-guided quality assessment and protocol optimization for diagnostic MRI, tailored to the scanner, coils and imaging task.
MRI physics consulting is available separately.
See our preliminary validation findings, submitted abstracts and recent presentations.
Tell us your institution, scanner and clinical question. We can arrange an introductory call to discuss scope and next steps.
