LUCY™ 3D QA Phantom End-to-End Stereotactic QA

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.

Key Features

  • Every component manufactured within 0.1 mm tolerance (the manufacturer spec)
  • End-to-end stereotactic QA in a single phantom — imaging through dose delivery
  • Interfaces with most commercial SRS frames and frameless systems
  • Multiple targeting inserts for varying QA scenarios
  • Dosimetry inserts for absolute, relative and point-dose measurements at isocentre

Applications

Every link in the SRS QA chain — one phantom

SRS / SRT end-to-end QA

Test every link in the stereotactic chain — imaging, fusion, planning, couch positioning, dose delivery — under patient-like conditions, with one phantom and one session.

MPPG 9.a compliance E2E

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.

Image fusion verification

Sub-millimetre inserts surface CT-to-MRI, CT-to-CBCT and CT-to-PET fusion errors before they affect a stereotactic plan.

MR distortion / geometric QA

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.

Radiosurgery dose QA

A16-class micro chambers in dosimetry inserts give absolute and relative dose measurements at the SRS isocentre — small-field-appropriate.

Frameless SRT commissioning

Commission mask-based frameless SRT systems with known-geometry targets across the major frame and frameless interfaces.

Why LUCY 3D?

0.1 mm
Per-component tolerance

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.

E2E
One phantom, one session

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.

Sarkar 2016
Peer-reviewed head-to-head

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.
