LUCY™ 3D QA Phantom — the SRS end-to-end citable backbone.

The Lucy 3D QA Phantom is built for the end-to-end portion of an SRS / SRT / SBRT QA programme. The evidence here has three layers: the AAPM standards that define the E2E phantom requirement (MPPG 9.a, TG-135, TG-101), one peer-reviewed head-to-head comparison that put Lucy 3D up against StereoPHAN (Sarkar 2016), and the End-to-end whitepaper that walks the workflow.

The full SRS end-to-end chain — five links, one phantom

AAPM MPPG 9.a sets a verbatim 72-hour on-site availability requirement for E2E phantoms. What does each of the five links of the chain look like, and which Lucy insert serves it? Sourced to Halvorsen 2017 + Sarkar 2016.
