Expertise for the way you use MRI.

Start with a focused question or build continuing support around your existing vendor and physics coverage.

MRI for radiotherapy

  • MRI simulation and the MRI components of MR-linac commissioning
  • Geometric-distortion assessment and SRS sequence optimization
  • Phantom baselines and continuing MRI QA review

MRI for radiology

  • MRI performance testing and protocol assessment
  • Customized pulse-sequence and image-quality optimization
  • QA workflows and continuing physicist support

MRI physics consulting is available separately from software programs in development.

Start with one focused project.

Agree on selected sequences and deliverables for a paid assessment, then discuss continuing support if useful.

01

Define

Agree scanner, application, sequences and questions.

02

Measure

Agreed testing plan and compatible phantom measurements.

03

Review and optimize

Documented findings and practical protocol recommendations.

04

Verify and follow

Review repeat measurements, establish a baseline and plan ongoing QA.

Your clinical team retains protocol approval and patient-care decisions.

MRIQA RadOnc Phantom QA

Our first product • In validation

A tool supporting site-specific MRI assessment and consulting, using GHead and ACR phantom measurements analyzed in SpinTecx software.

GHead

Characterize geometric distortion using a controlled head-shaped lattice and air-cavity interfaces.

ACR

Assess scanner image quality and evaluate your clinical sequences on a standard phantom.

MRIQA RadOnc

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

Preliminary UCLA phantom evaluation

Siemens MAGNETOM Sola 1.5 T • 3D MPRAGE test protocol • 8 October 2026

GHead displacement, 95th percentile

Vendor 3D correction OFF

1.24 mm

Vendor 3D correction ON

0.50 mm

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.

Research & Future Development

MRIQA RadOnc Clinical QA

Research Only

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.

MRIQA Radiology

In Development

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.
