One hole is at center hole and four are around the perimeter, 90° apart and 1 cm from center to the outside edge of the phantom.

    Features

  • Usable on all CT scanners
  • Simulates infant to large adult patients
  • Made from tissue equivalent epoxy

           IMRT Homogeneous Phantom.       


    Computerized Imaging Reference Systems, Inc! Complete QA from CT imaging to dose verification

    Features

  • Check 2D dose distributions (3D distributions optional)
  • Point dose measurements in multiple planes
  • Calibrate film with ion chamber quickly verify individual patient treatment plans
  • Correlate CTU to electron density

  • The CIRS Model 002H5 IMRT Phantom for Film and Ion chamber Dosimetry is designed to address the complex issues surrounding commissioning and comparison of treatment planning systems while providing a simple yet reliable method for verification of individual patient plans and delivery.

    The 002H5 is homogeneous and elliptical in shape. It properly represents human anatomy in size and proportion. It measures 30 cm long x 30 cm wide x 20 cm thick (PA). The phantom is manufactured from a unique proprietary material that faithfully mimics water within 1% from 50 keV to 25 MeV.

    Water equivalent interchangeable rod inserts accommodate ionization chambers allowing for point dose measurements in multiple planes within the phantom. The phantom also supports radiographic or GafChromic® film at mid-plane in the phantom for analysis of dose distributions. Optional inserts are available to support a variety of other detectors including TLD's, MOSFET, and diodes.



    Handling, assembly and proper orientation of the phantom is made easy with the use of a unique alignment base and holding device. The surfaces of the phantom are etched for ease of laser alignment, and CT markers ensure accurate film to plan registration.

    IMRT Verification System
    CIRS IMRT phantoms are manufactured from tissue equivalent materials that mimic within 1% from 50 keV to 25 MeV for accurate simulation from CT planning to treatment delivery. An interchangeable rod design allows the phantom to accommodate a multitude of dose measurement devices such as ion chambers, TLD, diodes and MOSFET's in the same location within the phantom. Phantom cross sections accommodate GafChromic® or standard ready-pack films.

    Model 002H5 Includes:
    2) - Tissue equivalent sections, one drilled to accommodate solid rod inserts
    1) - Set of CT to film fiducial markers
    5) - Water equivalent solid rod inserts
    1) - Water equivalent rod insert with ion chamber cavity
    1) - Alignment Base
    1) - Holding device

           Nested CT Dose Phantom Kit for Pediatric/Adult Head and Body.       


    Fluke Biomedical, Inc.
  • Uniquely designed for pediatric and adult computed tomography dose index (CTDI) in a lightweight (44 lb, 20kg) total package
  • Can be used with new multi-detector (MDCT) units
  • Meets requirements of FDA performance standards
  • All new carrying case with wheels and pull handle
  • Case includes space for CT Ion Chambers (purchased separately)

  • Introduction
    The innovative nested CT Dose Phantom can be used with any computed tomography (CT) system designed to image pediatric and adult head and body. Each phantom segment can provide separate dose information. When performing dose profile measurements, the dose phantoms allow the user to collect information for the maximum, minimum and mid-range value of the nominal tomographic section thickness.

    This essential phantom kit consists of three parts: an adult body phantom, an adult head phantom that doubles as a pediatric body phantom and the new pediatric head phantom, nested together for easy storage and convenient transport. (All are made of solid acrylic with diameters of 32, 16 and 10 cm, respectively.) Each part contains four probe holes around the perimeter, 90° apart and 1 cm from the edge and the pediatric head (center insert) has one probe hole in its center. The inside diameter of the holes is 1.31 cm. Each part includes five acrylic rods for plugging all the holes in the phantom. A sturdy storage and carrying case with wheels and pull handle that holds all three phantoms is included; as an option, a smaller case without wheels is available.

    Applications
    The CT Dose Phantoms were designed in accordance with the Food and Drug Administration's performance standard for diagnostic x-ray systems, which includes regulations specifically applicable to CT systems (21 CFR 1020.33).
