ART PhantomAnthropomorphic Radiotherapy QA Phantom — ICRU-44
Refined Alderson RANDO design — 2.5 cm transected horizontal slices held between aluminium end plates by nylon tie rods. Tissue-equivalent slices with bone-equivalent / soft-tissue-equivalent / lung-equivalent pin holes accept TLD, OSL, MOSFET and ion-chamber dosimeters. Male (175 cm / 73.5 kg / 36 sections) and female (155 cm / 50 kg / 33 sections) variants. ICRU-44 compliant. The end-to-end treatment-chain QA workhorse used in ~10,000 sites worldwide over three decades.
Key Features
- Refined Alderson RANDO design — three decades of clinical-physics use across ~10,000 sites worldwide
- ICRU-44 compliant tissue-equivalent material — designed within sophisticated technological constraints
- 2.5 cm horizontal slice thickness for fine-resolution depth-dose verification
- Male variant: 175 cm tall, 73.5 kg, 36 sections (head sections 0–9, body sections 10–35)
- Female variant: 155 cm tall, 50 kg, 33 sections (head 0–9, body 10–32)

Applications
The dosimetry phantom three decades of clinical physics has built around
TPS validation
New treatment planning system commissioning — irradiate the phantom with a series of beams of known dose, read the in-slice dosimeters, compare against the TPS prediction. ICRU-44 tissue equivalence means the comparison is direct, no conversion factors.
End-to-end treatment-chain QA
Plan a patient-like treatment on the phantom, deliver it on the linac, measure delivered dose at dosimeter positions. Catches errors anywhere in the chain — imaging, contouring, planning, delivery, dosimetry analysis.
AAPM TG-119 / TG-218 IMRT QA
IMRT / VMAT commissioning per AAPM TG-119 (commissioning) and TG-218 (patient-specific QA). The ART phantom holds dosimeters at clinically relevant anatomical positions, not just flat-slab geometry.
Brachytherapy QA
High-dose-rate and low-dose-rate brachytherapy treatment-plan verification. Tissue-equivalent slices ensure the measured dose maps onto patient dose without source-strength-specific conversion factors.
Electron-beam dose verification
Electron-beam dose-profile work in head-and-neck and chest-wall geometries. Bone and lung inserts give the realistic high- and low-density inhomogeneities clinical electron treatments encounter.
Teaching and training
Medical-physics residency programmes use the ART phantom as the hands-on dosimetry teaching tool — students irradiate, read dosimeters, compare to TPS, and walk through the chain of measurement before they work on patient cases.
Why ART Phantom?
Every slice and every insert is calibrated to ICRU-44 tissue-equivalent specifications. A measured dose in the phantom corresponds directly to a patient dose at the same anatomical position — no conversion factor that has to be defended at accreditation review.
Approximately 10,000 ART phantoms are in routine clinical use globally. The dosimetry results from your phantom are comparable against published peer-reviewed datasets generated on the same platform — the most-used physical phantom in radiation oncology QA.
The 2.5 cm slice thickness puts a dosimeter measurement point every 2.5 cm down the patient axis. Depth-dose verification and PTV-OAR dose differential checks are resolved at clinically meaningful scales — not the 5 cm slabs of cheaper phantoms.
