Independent, board-certified consulting for MR-in-RT: TG-284 commissioning, geometric distortion QA, SRS sequence optimization, and MR-linac/MR-sim program support. We work alongside your physics team — we don't replace it.
Serving clients nationwide — on-site, remote, and hybrid engagement models.
MR-in-RT Physics Services
SpinTecx provides board-certified MR-in-RT consulting through fixed-scope projects, annual audits, fractional program support, and ongoing QA retainers. Every new engagement in this service line is focused exclusively on the MRI side of radiation therapy.
MR Simulation & TG-284 Commissioning
Full commissioning of MRI simulators and MR systems used for RT planning, aligned with AAPM TG-284: geometric distortion characterization, sequence validation, immobilization and coil setup, and audit-ready baseline documentation.
SRS MRI Sequence Optimization
Specialized optimization of MRI protocols for stereotactic radiosurgery targets, using a proprietary phantom-based methodology to evaluate spatial fidelity for small targets and tight treatment margins.
Annual MR-in-RT Audit
Independent yearly audit of your MR-in-RT program informed by TG-284 recommendations and site-specific acceptance criteria: distortion re-baseline, protocol drift review, and a prioritized corrective-action report.
MR-in-RT QA Retainer
Ongoing remote physics oversight for your MR-in-RT program: monthly QA review, trend analysis, protocol change support, and on-call physicist access.
"RT-Ready" Imaging Center Program
For imaging centers that want to serve radiation oncology referrals: we validate geometric accuracy, build RT-specific protocols, and document your scanners as RT-planning ready.
Remote Protocol & Program Reviews
Fixed-scope remote reviews of MRI protocols, distortion QA data, or MR-in-RT program design — a fast, low-commitment way to get an independent expert opinion.
A Complement to Your Physics Team — Never a Replacement
SpinTecx does not market or accept new engagements for routine linac QA, TG-51 calibrations, treatment plan checks, or general machine-physics coverage. We do one thing at a specialist level: the MRI side of radiation therapy. That means your local physics team or consulting group keeps its scope — and gains an MR-in-RT subspecialist on demand.
What We Do
MR simulation commissioning, geometric distortion QA, SRS sequence optimization, MR-linac/MR-sim program support, and MR-in-RT audits.
What We Don't Pursue for New Engagements
Linac QA, TG-51 calibrations, treatment plan checks, or routine machine physics coverage.
How We Fit
Your local physics team or consulting group keeps its full scope. SpinTecx adds MR-in-RT subspecialty depth on demand.
Partner With Us
Physics consulting groups: offer MR-in-RT services to your hospital clients under your own engagement. SpinTecx works as a subcontracted subspecialist — white-label or named, your choice — covering TG-284 commissioning, MR-in-RT audits, and SRS sequence optimization while you own the client relationship.
You Own the Client
Your group maintains the primary relationship with the hospital or health system. SpinTecx operates as your MR-in-RT subspecialist — visible or behind the scenes.
Expand Your Service Line
Add TG-284 commissioning, MR-in-RT audits, and SRS sequence optimization to your offering without hiring a full-time MR physicist.
Flexible Arrangements
White-label or named subcontracting. Per-project or retainer. Structured to fit your existing client agreements.

Why MRI Accuracy Matters in Radiation Therapy
Geometric distortion in MRI can introduce systematic errors in target delineation. This is especially consequential in SRS, where small targets and tight margins demand careful control of spatial uncertainty. Independent, phantom-based validation provides direct evidence that MRI data meet the geometric requirements of the intended treatment-planning workflow.
