Dosimetry Phantom for Repeatable Beam Calibration

Inconsistent material density in quality assurance tools compromises the accuracy of radiation therapy workflows. This dosimetry phantom provides water equivalent absorption for absolute dose checks to ensure clinical accuracy. 

How a Dosimetry Phantom Works

The hardware serves as a reference object to verify beam delivery during system commissioning. RW3 solid water material replicates human soft tissue with a density of 1.045 g/cm3 to ensure accurate radiation absorption. Clinicians utilize this setup to validate complex dose distributions and perform depth-dose measurements without exposing patients to test radiation.

Dosimetry Phantom Systems by gKteso

We provide specialized quality assurance tools designed for submillimeter resolution and OEM system integration. These modular systems accommodate various detectors to support diverse clinical and research environments.

RW3 Solid Water Standard Phantoms

These units provide the base technology for clinical dosimetry. As a standard for solid water phantoms, the RW3 material matches human soft tissue above 99% to ensure repeatable dose measurements for photon and electron beams.

EASY SLAB Phantom

This modular system supports routine absolute dose checks and distribution verification. It utilizes stackable slabs to accommodate more than 60 different detectors for exact coordinate measurements.

EASY CUBE Phantom

This tool enables end to end quality assurance and imaging validation across multiple modalities. The cube structure allows for versatile positioning of inserts to simulate various anatomical regions.

Anthropomorphic Head Phantom

This unit replicates human head anatomy including bone and muscle equivalent inserts for realistic radiotherapy validation. It supports surface guided radiotherapy calibration and imaging validation during the development cycle.

Your Advantages with gKteso

Validated Attenuation

RW3 material matches human soft tissue above 99 percent for photon and electron beams. This ensures identical absorption rates during every fractionated treatment to prevent dose calculation errors.

Mechanical Resolution

Manufacturing processes at our local facility maintain mechanical tolerances below 0.02 mm for every module. This submillimeter resolution supports the tight requirements of stereotactic protocols and VMAT delivery.

Radiation Longevity

Selection of radiation hard polymers prevents browning or density drift over many years of high dose exposure. The hardware maintains its mechanical and dosimetric properties to ensure long term reproducibility.

Regulatory Acceleration

Provision of FDA ready documentation and ISO 13485 files streamlines the certification of your radiotherapy platform. This integrated risk management approach reduces the time to market for next generation linear accelerators.
