Klarity SRS System

The CIRS Dynamic Thorax Phantom is a precision instrument for investigating and minimizing the impact of tumor motion inside the lung. It provides known, accurate and repeatable three‐dimensional target motion inside a tissue equivalent phantom. It is designed for comprehensive analysis of image acquisition, planning and dose delivery in image‐guided radiation therapy. The phantom body represents an average human thorax in shape, proportion and composition. A lung equivalent rod containing a spherical target and or various detectors is inserted into the lung equivalent lobe of the phantom. The body is connected to a motion actuator box that induces three‐dimensional target motion through linear translation and rotation of the lung equivalent rod. Motion of the rod itself is radiographically invisible due to its matching density with the surrounding material. The target and its motion, given its density difference, can be resolved.
• Complex 3D tumor motion within the lung
• Sub‐millimeter accuracy and reproducibility
• Tissue equivalent from 50 keV to 15 MeV
• Compatible with TLD, MOSFET Dose Gel, Micro‐chamber, PET/CT targets and film

Cube 20 Phantom

The CIRS Model 009 Cube 20 Phantom was designed for routine QA in RT and IMRT applications where ease of use and quick set‐up are important.

The Cube 20 Phantom is manufactured from Plastic Water® DT which faithfully mimics the Linear attenuations of water within 1% from 50KeV to 15 MeV. This enables complete QA from CT image acquisitions to therapy dose verifications.

Plastic Water

Unlike other water equivalent plastics on the market, Plastic Water® is flexible and resists breakage under impact. Plastic Water is the only calibration material available in 1 mm thicknesses. Original Plastic Water® is the only material which agrees with true water within 0.5% above 7 MeV. Custom cavities are available to accommodate any ion chamber on the market (simply provide detailed drawings when ordering).*

The high dose per fraction associated with SBRT necessitates a high degree of accuracy in target localization and dose delivery. Small errors can result in significant under treatment of portions of the tumor volume and over dosages of nearby normal tissues. The E2E® SBRT Phantom provides a means to check the entire treatment chain during commissioning and routine QA.

The Model 036A­CVXX­xx* is an anthropomorphic thorax body containing articulated spine, ribs and lungs.
• All materials are suitable for use in kV and MV energies.
• Thorax with articulated spine, ribs and lungs
• Optional Abdomen with Gafchromic Film insert
• High Resolution Anthropomorphic Characterstics

(Whole Body Phantoms)

CIRS ATOM® phantoms are a full line of anthropomorphic, cross sectional dosimetry phantoms designed to investigate organ dose, whole body effective dose as well as verification of delivery of therapeutic radiation doses. ATOM is the only line of dosimetry phantoms to range in sizes from newborn to adult. Six models are available: newborn, 1‐ year, 5‐year and 10‐year old pediatric phantoms as well as adult male and female phantoms.
Each phantom is sectional in design with traditional 25 mm thick sections. The sectional surfaces are extremely flat and smooth and do not require any special coatings or treatment. This results in minimal interfaces between the slabs when viewed in a scout or projection X‐ray. The ATOM line also differs from other dosimetry phantoms by providing optimized TLD locations specific to 21 inner organs.
Tissue‐equivalent epoxy resins are used in all aspects of the phantom. CIRS technology offers superior tissue simulation Dosimetry Verification Phantoms by covering a wider range of energy levels from diagnostic to therapeutic. In addition, all bones are homogeneous and are formulated to represent age appropriate, average bone composition. CIRS bone formulations offer distinct advantages over natural skeletons and other types of simulated bone.

• Phantom models cover a wide range of patient ages
• Organ specific dosimetry with minimal detectors
• Superior tissue simulation and lifelike imaging properties
• Homogeneous bone
• Accommodates wide variety of detectors

MRI Distortion Phantom for SRS

CIRS Model 603A was designed for assessment of MR image distortion in Stereotactic Radiosurgery Planning. It is also a useful tool for verifying image fusion and deformable image registration algorithms used in various treatment planning systems. The tissue equivalent, anthropomorphic design provides the closest conditions to a clinical imaging scenario. The phantom can be imaged using X‐ray, Computed Tomography and Magnetic Resonance. It images well with all MRI sequences tested to date, including T1 weighted, T2 weighted, 3D Time of Flight, MPRAGE and CISS.

Brachytherapy QA Phantom

A robust quality assurance prostate brachytherapy QA program is essential to ensure accurate image‐guidance and dosimetry calculations. The CIRS Model 045A, used in conjunction with the CIRS Model 053G Ultrasound Prostate Phantom, offers a complete solution for implementing a QA program specific to transrectal ultrasound used for guidance of prostate brachytherapy as recommended by AAPM Task Group 128.
