RadMachine Adds Automated Dose Rate & Collimator Speed Analysis

We’re excited to introduce a major enhancement to the RadMachine Therapy’s Image Analysis workspace. Automated VMAT Dose Rate and Collimator Speed Testing for Varian’s RapidArc Dynamic delivery. 

What This Means for Clinics

RadMachine now automates a critical part of RapidArc Dynamic verification. The new test analyzes images captured during arc delivery to confirm:

  • Dose rate remains within tolerance, even as the machine modulates the beam intensity.
  • Collimator rotation speed remains consistent throughout the arc.
  • Gantry rotation speed remains stable across the full arc.

This automation removes the tedious manual review steps often associated with RapidArc Dynamic QA and eliminates the need for spreadsheets or external analysis tools. It helps catch deviations before they affect patient treatments. It also automates the analysis, freeing up time for high-value clinical work. 

 

Why It Matters

RapidArc Dynamic delivery is complex. Dose rate, MLC motion, and collimator speed must all work together in a carefully choreographed sequence. Any deviation in collimator rotation or dose rate can introduce uncertainty in dose delivery and potentially impact patient care.

Traditional workflows require manual data capture and time consuming evaluation. RadMachine eliminates these challenges by providing: 

  • Automated Analysis
  • Built-in trending to spot changes early
  • Consistent, repeatable test results

Physics teams gain greater visibility, higher confidence, and less back-and-forth with secondary analysis tools.

 

STEP 1

Capture the images during RapidArc Dynamic delivery.

STEP 2

Upload the images in RadMachine’s Images Analysis workspace manually, or via Local Agent Automation.

STEP 3

RadMachine automatically evaluates:
    - Dose rate stability
    - Collimator speed
    - Tolerance compliance

STEP 4

Results are visualized and stored directly within the RadMachine system, enabling long-term trending and compliance tracking.

No manual calculations. No spreadsheets.

 

Key Benefits:

Automated analysis of RapidArc Dynamic

Removes manual effort, reduces risk of human error

Dose rate + collimator speed verification

Ensures consistent machine performance during complex modulated deliveries

Centralized trending + documentation

Supports audit readiness and continuous machine performance monitoring

Works inside existing RadMachine workflows

No new process or tool required, just add images and analyze

 

A More Confident QA Workflow

This enhancement reinforces RadMachine’s commitment to modern, automated QA. With support for Dynamic IMRT and VMAT dose rate and collimator speed analysis, clinicians have a new level of insight into machine performance:

  • Faster QA
  • Higher precision
  • Greater confidence in every treatment
