RapidArc patient QA

Use your portal imager as absolute dosimeter to verify RapidArc plans following these steps:

• Replace patient 3D model with water phantom and reset gantry angles to zero for dose calculation
• Calculate verification plan using YOUR CLINICAL dose calculation algorithm
• DICOM export dose plane at d_max as a reference matrix
• Deliver the RapidArc plan normal way while acquiring integrated image
• Compare calculated versus acquired dose matrices using Epiqa

Benefits of using Epiqa for RapidArc plan QA:

• Simple QA plan preparation
• Instant detector preparation for measurement – just deploy Portal Vision arm
• Easy QA plan delivery – can be performed by therapist
• Fast data export – export only 4 DICOM objects
• Quick results evaluation. In just few minutes user can print final protocol for approval
• The method verifies not just the delivery device but also TPS performance
