Dosimetric Precision: Target Delineation and Plan Optimization

Our certified dosimetrists utilize advanced RT (Radiation Therapy) modalities to ensure the highest Conformality Index and minimize Organ-at-Risk (OAR) toxicity.

Advanced Delineation and Target Volumes

Rigorous application of the ICRU-defined target volumes (GTV, CTV, PTV) and adaptive contouring protocols is mandatory for all complex cases (RS, SBRT/SBRS).

4D-CT & Motion Management: Expertise in delineating Internal Target Volumes (ITV) for respiratory-gated treatments.
OAR Constraint Management: Detailed review and optimization against protocol-specific Dose Volume Histogram (DVH) limits, prioritizing spinal cord and brainstem sparing.
Image Fusion & Adaptive RT: Utilization of multi-modality registration (MRI, PET) to accurately define gross tumor volume.

IMRT/VMAT Plan Optimization

We drive Treatment Planning System (TPS) objectives to maximize Homogeneity Index while achieving mandatory PTV coverage across all sites.

Plan Objectives Cascade: Structured optimization algorithms designed to manage highly non-linear IMRT/VMAT fluence distribution.
SRS/SBRT Planning: Dedicated single-isocenter, multi-target planning for cranial and extracranial stereotactic radiation surgery.
Dose Distribution Analysis: Final review of isodose lines to confirm spatial conformity, ensuring cold spots are eliminated from the prescription volume.

Medical Physics Validation: Beam Modeling and Dose Integrity

Our board-certified physicists execute mandatory Independent Dose Recalculation (IDR) and system integrity checks to validate the entire treatment chain.

Dose Calculation & Modeling Fidelity

Verification of treatment prescription requires absolute confidence in the TPS beam modeling, particularly in complex low-density (lung) and high-density (bone) interfaces.

Monte Carlo Validation: Utilizing gold-standard calculation algorithms for secondary verification of MU (Monitor Unit) and dose in highly heterogeneous anatomy.
Beam Profile Integrity: Auditing lateral dose profiles and PDD (Percent Depth Dose) data against measured commissioning data.
Machine Parameter Review: Cross-check of MLC (Multi-Leaf Collimator) model, Gantry angle, and couch position tolerances in the Record & Verify (R&V) system.

Plan Quality Assurance (PQA)

Every treatment plan undergoes a full physics audit prior to initial fraction delivery to ensure the Dose/MU output is verifiable on the Linac.

Patient-Specific QA: Recommendations for pre-treatment IMRT QA using phantom measurements or calculation-based methods (e.g., Portal Dosimetry).
Error and Deviation Protocol: Reporting and follow-up on any observed dose or positional deviations exceeding institutional tolerance thresholds.
Fractionation Scheme Compliance: Verification of prescription adherence across all fractions, especially for hyper-fractionated or dose-escalated regimes.

QA & Compliance: System Reliability and Regulatory Integrity

Dedicated assurance protocols ensuring the treatment delivery equipment maintains optimal performance, regulatory fidelity, and patient safety.

Integrated Machine QA and Safety

Execution of routine QA protocols (Daily, Monthly, Annual) to verify the electromechanical and dosimetric parameters of the Linear Accelerator (Linac).

Dosimetric Consistency: Daily output constancy checks using dedicated detectors (e.g., ion chamber) to verify dose per MU stability.
Imaging & Isocenter Accuracy: Verification of kV/MV imaging chain alignment and mechanical/radiation isocenter concordance.
Safety Interlocks: Systematic testing of hardware and software safety interlocks, including collision detection and emergency shutdown mechanisms.

Regulatory Compliance and Commissioning

Full management of regulatory auditing and the rigorous process of new system acceptance and commissioning per AAPM Task Group reports.

Acceptance Testing (AT): Integrated testing to ensure vendor specifications and contractual performance metrics are met prior to clinical use.
Clinical Commissioning: Complete measurement and modeling of all photon and electron energies for the TPS, validated with patient simulation data.
Regulatory Auditing: Preparation for and execution of state and federal audits, ensuring full documentation and adherence to licensing requirements.

Flexible Expert Planning: Managing Peak Demand

Strategic Resource Augmentation

The challenge of managing varying patient loads and specialized skill requirements is solved through our flexible staffing models. We ensure you never compromise quality due to capacity limits.

✓
Handle Peak Demand: Scale up dosimetry and physics coverage immediately during seasonal highs, new technology adoption, or sudden staff shortages.
✓
Sub-Specialty Access: Instantly access experts certified in specific niches (e.g., pediatric planning, brachytherapy, MR-Linac workflow) without permanent hiring overhead.
✓
Cost Efficiency: Convert fixed operational costs into variable expenses, paying only for the expert support you utilize when you need it most.

Resource Scenario Simulator

Understand how Roentgen helps alleviate common departmental pressures:

Scenario A: Staff Absence

A physicist goes on leave for 6 weeks. Roentgen provides certified remote coverage for routine and complex planning within 48 hours, ensuring zero drop in patient start rate.

Scenario B: Technology Launch

You launch a new SBRT program. Roentgen supplies the required expert planning hours and site-specific training until your in-house team is fully proficient.

Scenario C: Planning Backlog

A sudden patient surge creates a 3-day planning backlog. Our team integrates remotely to clear the queue within 24 hours, restoring departmental efficiency.

Guaranteed Performance: 95% Uptime Assurance

CLINICAL UPTIME PLEDGE

WE GUARANTEE 95% UPTIME.

Our service level agreements (SLAs) guarantee that your linear accelerator and associated systems will be operational for clinical use 95% of the time, minimizing treatment delays.

Proactive Diagnostics

Continuous remote monitoring feeds data to our AI engine, allowing us to predict and mitigate potential component failures before they impact treatment delivery.

Rapid Triage & Resolution

Our technical support is available 24/7/365. Remote issue resolution begins within minutes, and on-site field service engineers are dispatched with guaranteed response times.

Part Logistics Management

We manage a global supply chain to ensure critical replacement parts are available and delivered quickly, directly minimizing the mean time to repair (MTTR).

Validated Excellence: Select Case Studies

Case Study 1: SBRT Program Launch

Challenge:

A major regional center was limited by in-house SBRT planning experience, delaying the launch of their high-value lung SBRT program.

Solution:

Roentgen provided dedicated SBRT-certified physicists who remotely planned the first 25 complex cases (including Monte Carlo) and simultaneously trained the in-house team on advanced contouring and delivery techniques.

Outcome:

Program launched 4 months ahead of schedule with 100% plan quality score.

Case Study 2: Uptime Recovery

Challenge:

A critical Linac experienced an unexpected system component failure, resulting in an 48-hour unplanned outage and a major backlog of patients.

Solution:

Roentgen's Uptime Assurance service mobilized: the spare part was fast-tracked via dedicated logistics, and a field engineer arrived within the 4-hour SLA. Simultaneously, our planning team absorbed the patient backlog.

Outcome:

System restored in under 6 hours; patient backlog cleared within 1 day, maintaining the 95% annual uptime guarantee.
