Automate, Simplify and now Extend your Machine QA

Analyzing, trending, and reporting TG142 recommended tests... Automatically

QUASAR™ eQA 2.0 software simplifies Machine QA through automated EPID image analysis, eliminating the need to purchase film. This time and cost-saving application automates the analysis and reporting for important TG142 recommended QA tests(1).

 
QUASAR™ eQA 2.0 includes a central application (QUASAR Core) which interacts with a SQL database and runs unattended in the background.  It automatically analyzes EPID images, and manages communications, user roles, security settings and machine configurations.  
 
 
The QUASAR™ eQA 2.0 client includes a DICOM viewer which interacts with the central application to enable the following functions:
  • Visualize and approve test results
  • View database trends
  • Manage test configurations

Custom QA
Custom QA Forms
Consolidate all of your QA data
Save the results of any Quality Assurance test to the QUASAR™ eQA database by creating custom QA forms that suit your clinic’s needs. Input data such as; boolean, single value, and multi-value (with calculations) to perform trend analysis with ease.  Generate reports to share with physicist and radiation therapists.
QA Scheduler
QA Scheduler
Plan your work, work your plan
The QA Scheduler enables users to plan process flows and complete quality assurance processes.  Provide timelines for daily, weekly, monthly and annual quality assurance tests.  Organize your workload per LINAC and per staff member.  Track and report the time allocated for your quality assurance process.

Accessories to help you maintain a compliant facility

Cross Hairs

 

Crosshair & Field Edge Markers
The crosshair and field edge marker templates are used as image reference markers when using QUASAR™ eQA software. Each template contains one or more radio-opaque markers which are detected within the analyzed images in order to calculate pixel scaling and identify the center and size of a light field.
 
Specifications:
  • 29 cm x 29 cm x 6 mm thick acrylic cross hair
  • Multiple 3 mm diameter tungsten markers embedded in acrylic
  • Four acrylic field edge markers to mark field sizes from 6 cm x 6 cm and larger
BB Train

 

BB Train
The BB Train phantom is used in two main QUASAR™ eQA 2.0 tests: Half Beam Block Junction at Orthogonal Angles and Treatment Couch Motion and Rotation. The BB Train phantom is used as a reference point in space during the execution of these tests.
 
Specifications:
  • 28 cm long by 2.5 cm diameter acrylic rod
  • Six 7/16” Steel BB embedded in rod
Winston-Lutz Wand

 

Winston-Lutz Wand
The Winston-Lutz Wand is used in conjunction with the MV Beam and portal imager to quantify mechanical outputs of the LINAC such as: relative gantry, collimator and table isocenter positions and overall diameters, linear positions, gantry sag, and jaw symmetry.
 
Specifications:
  • XYZ Micro Stage for positioning wand
  • 7/16” Steel BB
  • Counterbalanced stand for ease of use
  • Compatible with LINACS and EPIDS from multiple vendors
  • Comes with a convenient storage and carrying case
