COMPASS Patient Dose Analysis

Why COMPASS?

Radiation Therapy is advancing rapidly, improving treatment accuracy but also introducing new uncertainties and risks.

Ensure patient safety and better treatment outcomes by eliminating the unknown.

COMPASS provides you with critical details needed for confident plan verification and approval.

Key Benefits for Physician & Clinician

Maximize Efficiency
COMPASS relates standard physics acceptance criteria to 3D patient dose revealing the clinical relevance of discrepancies

Minimize Errors
COMPASS gives you the power to analyze the entire treatment chain from the plan to the patient

Better Outcomes
COMPASS provides a platform to combine the expertise of the RT team, putting the clinical protocol in the center of plan verification

COMPASS Efficiency

Fastest plan analysis based on familiar standard physics acceptance criteria. COMPASS plan QA solution allows a rapid pass or fails analysis. In case of substantial dose discrepancies of plan vs. Measurements COMPASS extends into 3D patient anatomy based analysis.

• fast analysis of response difference (plan vs. delivered)
• precise evaluation per fi eld or for each segment/control point
• reliable check even for small MLC errors
• Fast overview of all frames (planned vs. Measured) on control point level
• Check references vs. Planned consistency for small fluctuations

Measurement accuracy down to the details

• seamless measurement of the whole plan delivery
• accurate analysis of rotational plans
• individual check for each IMRT segment (step and shoot or dynamic)
• precise measurement of gantry angle per frame
• rapid response measurement with sampling rate up to 20 frames/sec

COMPASS Accuracy and Reliability with Patient Anatomy

COMPASS enables the Radiation Therapy Team to combine their physics and clinical expertise for a full treatment evaluation based on the clinical protocol. The team benefi ts from a complete understanding of the clinical relevance of dose discrepancies and necessary corrective action, speeding up processes and enabling earlier and better patient treatment.

Fastest overview of the entire plan

• immediate “FAIL” alert if predefined prescription doses and tolerances are missed
• automatic OAR and PTV analysis based on your clinical protocols
• comparative DVH enables fastest assessment of reference (TPS) vs. delivered dose
• full visualization fl exibility (all ROI’s or one by one)

Reliable analysis of dose discrepancy details

• the % difference between reference (TPS) and actual measured dose (Compass) is determined in the patient CT
• immediate understanding of dose discrepancies in single organs

Most accurate verification of clinical relevance of errors

• patient dose guided decisions instead of traditional physics pass criteria
• analyze doses in absolute Gy (gray) values; verify target average dose and homogeneity, analyze OAR dose constraints
• understand clinical relevance, gain full treatment confi dence and better outcome

COMPASS Comprehensive Reporting

• fast one-click automatic generation of comprehensive report
• patient individual reporting for electronic records, print or export to Excel
• indication specific template for consistent report generation
• including DVH, displays of planned and reference patient dose, dose difference etc.

COMPASS software is developed in cooperation with RaySearch Laboratories AB.
