Lineup
Water-Equivalent Slab Phantom
The Key Water
A new phantom material for dose measurement, designed with relative electron density, effective atomic number, and stopping-power ratio more closely matched to water.
Radiotherapy / Water-Equivalent Slab Phantom
- For greater ease of use, two sizes are available: 200 x 200 mm and 300 x 300 mm.
- Hole machining for dosimeters is available – please inquire for details.

Electron Density Phantom
The Key Density
Smooth creation of CT-value conversion tables from imaging to treatment
Radiotherapy / Water-Equivalent Slab Phantom / Computer Tomography
- CT imaging plays a key role in correcting for tissue inhomogeneities in radiation treatment planning.
- Various tissue-equivalent rods can be positioned freely in the head and torso base modules, enabling CT-to-electron density correlation measurements.
Dynamic Phantom Platform
The Key Dynamic
Movable platform capable of reproducing arbitrary respiratory motion
Radiotherapy / Respiratory Gating / Quality Assurance
- This system enables accurate evaluation of respiratory tracking and synchronization by accommodating not only dose measurement phantoms but also CT, nuclear medicine, and anthropomorphic phantoms.
- This phantom simulating abdominal surface movement during breathing is installed. Respiratory gating sensors can also be attached.
WHAT FOR
This phantom is specifically engineered to replicate human motion, offering a reliable solution for a wide range of applications in radiotherapy and medical imaging (including evaluation of the accuracy of respiratory tracking and gating). It was designed to accommodate various types of phantoms, such as dosimetry phantoms, CT phantoms, nuclear medicine phantoms, and anthropomorphic phantoms.
It is equipped with a surrogate simulated abdomen that reproduces body surface motion during respiration. A respiratory gating sensor can also be attached.
