How Engagements Work

Engagements are structured to minimize administrative burden while maintaining technical clarity — from initial consultation through final deliverable.

01
1. Initial Consultation

A focused discussion of your technical requirements, timeline, and regulatory context. We identify the right scope and coverage model for your program.

02
2. Scope, Timeline & Proposal

Within 48 hours, you receive a written scope of work with specific deliverables, measurement protocols, timeline milestones, and transparent pricing.

03
3. Delivery & Documentation

We execute the engagement per plan, deliver comprehensive documentation with clear findings and recommendations, and remain available for follow-up.

MRI Physics & Quality Assurance

Geometric accuracy and image quality are foundational to both diagnostic MRI and MRI-guided radiation therapy. SpinTecx provides MRI QA programs aligned with ACR guidelines, supporting spatial consistency, system performance monitoring, and imaging protocol integrity.

Why MRI QA Matters

Geometric distortion in MRI can compromise diagnostic accuracy and introduce systematic errors in radiation therapy target delineation. Our QA programs quantify distortion characteristics, establish baseline performance metrics, and provide trending analysis to support early detection of system changes.

QA Program Design

Custom QA schedules aligned with ACR guidelines, routine performance monitoring, acceptance baseline establishment, and tolerance specification for your clinical applications.

Geometric Distortion & Spatial Integrity

3D distortion mapping, gradient linearity assessment, spatial accuracy verification, and long-term stability trending using specialized phantoms.

MRI Safety & Operations

Safety policy review, workflow guidance for complex protocols, equipment specification review for new installations, and accreditation documentation support.

MRI for Radiation Oncology

MR simulation QA, imaging protocol optimization for treatment planning, geometric accuracy validation for target delineation, and MRgRT readiness assessment.

Typical Deliverables:

  • QA protocol documents and measurement templates
  • Baseline performance reports with acceptance criteria
  • Distortion maps and spatial accuracy summaries
  • Long-term trend analysis and corrective action recommendations
Advanced MRI Expertise

Specialized expertise in MRI geometric fidelity, distortion quantification, MR simulation for radiation therapy, and quantitative imaging workflows where spatial accuracy directly impacts clinical decisions. Including expertise in MRI geometric distortion analysis for stereotactic radiosurgery, MR simulation, and quantitative imaging applications where sub-millimeter accuracy matters.
