One phantom for the full stereotactic QA chain — imaging, fusion, planning, dose delivery. Manufactured to 0.1 mm per-component tolerance so the phantom's own contribution to the end-to-end uncertainty budget stays near zero.
| Manufacturing tolerance | 0.1 mm per component (the manufacturer spec) |
| QA scope | End-to-end stereotactic — SRS / SRT / SBRT |
| Imaging modalities | CT, MRI, CBCT, kV / MV alignment imaging |
| Frame compatibility | Most commercial SRS frames and frameless systems |
| Targeting inserts | Multiple — for varying QA scenarios |
| Dosimetry inserts | Absolute, relative and point-dose at isocentre |
| Chamber compatibility | Exradin A16 micro chamber demonstrated in Sarkar 2016 study |
| MRI QA inserts | MR signal generator (oil-filled tank) + grid geometric-distortion insert |
| Standards alignment | AAPM MPPG 9.a (Halvorsen 2017); E2E QA per TG-101 / TG-135 frameworks |
| Peer-reviewed validation | Sarkar V et al., J Radiosurg SBRT 4(3):213–223 (2016) |
Every link in the SRS QA chain — one phantom
Test every link in the stereotactic chain — imaging, fusion, planning, couch positioning, dose delivery — under patient-like conditions, with one phantom and one session.
AAPM MPPG 9.a (Halvorsen 2017) requires "appropriate E2E phantoms for the scope of SRS-SBRT services offered, available for use on site in a timely manner (not to exceed 72 hr)." Lucy 3D is the fit.
Sub-millimetre inserts surface CT-to-MRI, CT-to-CBCT and CT-to-PET fusion errors before they affect a stereotactic plan.
The MR signal-generator and grid distortion insert (used in Sarkar 2016) characterise geometric distortion across the MRI field of view for MR-only or MR-guided planning.
A16-class micro chambers in dosimetry inserts give absolute and relative dose measurements at the SRS isocentre — small-field-appropriate.
Commission mask-based frameless SRT systems with known-geometry targets across the major frame and frameless interfaces.
Stereotactic uncertainty is the sum of every link in the chain — imaging, fusion, plan, delivery. The 0.1 mm per-component manufacturing tolerance keeps the phantom's own contribution to that sum as low as the standards allow.
From CT acquisition to dose readout — imaging QA, fusion QA, mechanical QA and dose QA in a single workflow. The MPPG 9.a "72-hour E2E availability" requirement becomes a one-tool problem.
Lucy 3D was put head-to-head against StereoPHAN in a 2016 J Radiosurg SBRT study, using an A16 micro chamber on a Brainlab headframe with MR distortion inserts. The reference comparison is published; you can read it cold.
