Sun Nuclear stereotactic QA
QA for SRS and SBRT in radiotherapy
SRS and SBRT are not generic patient QA cases. Small fields, steep dose gradients and tight geometry need a workflow that checks dose, detector resolution and end-to-end alignment together.
Decision points
What changes when the treatment is stereotactic
Small-field detail
Detector choice matters when field size, MLC shape and dose gradients leave little room for averaging.
Angles and setup
Stereotactic QA must consider angular response, phantom setup and positioning repeatability.
Less subjectivity
Digital QA can reduce film handling and make analysis more consistent across recurring checks.
Products to frame
Build the QA path around the clinical question
SRS MapCHECK
A film-less SRS/SBRT patient QA option for small-field dose measurements and absolute dose analysis. With StereoPHAN, Sun Nuclear describes angular, field-size and pulse-rate corrections for measurements from multiple angles.
StereoPHAN and SRS inserts
StereoPHAN is used for stereotactic end-to-end testing and SRS QA, with detector options such as ion chambers, film and SRS MapCHECK depending on the test.
E2E SBRT Phantom
For SBRT chain checks, an end-to-end phantom helps verify imaging, localization and targeting alignment before high-dose delivery workflows are relied on clinically.
How Interphysix frames it
A practical shortlist before quotation
Technique
Linac, cones, MLC plans, arc delivery and non-coplanar fields change the QA setup.
Existing software
The detector and phantom should fit the analysis workflow already used by the physics team.
Validation depth
Patient-specific QA, commissioning and end-to-end tests do not answer the same question.
For broader patient QA decisions, connect this page with ArcCHECK, MapCHECK and SunCHECK Patient. SRS/SBRT normally deserves its own branch in that discussion.
