    产品介绍:

    The Mammographic Accreditation Phantom Model 156 is
    designed to test the performance of a mammographic
    system by evaluation of the system’s ability to image
    small structures similar to those found clinically. Objects
    within the phantom were designed to simulate micro-calcifications,
    fibrous structures in ducts, and tumor-like masses,
    small structures that are important in the early detection
    of breast cancer. Test objects within the phantom
    range in size from those that should be visible on any system
    to objects that will be difficult to see even on the best
    mammographic systems.
    Storage and Handling
    Store the Mammographic Accreditation Phantom Model
    156 in a cool dry area avoiding temperature extreme such
    as intense heat and direct sunlight, or freezing temperatures.
    Impact stress may cause breakage.

    Product Description
    The Mammographic Phantom is made up of a wax block
    containing 16 various sets of test objects, a 3.3 cm (1.3
    in.) thick acrylic base, a tray for placement of the wax
    block, and a 0.3 cm (0.12 in.) thick cover. All of this
    together approximates a 4.2 cm compressed breast. Five
    groups of simulated micro-calcifications, six different size
    nylon fibers simulate fibrous structures, and five different
    size tumor-like masses are included in the wax insert.
    Figure 1 lists the sizes of the test objects and their position
    in relation to the notched corner of the wax block.

    A 4 mm thick, 10 mm diameter acrylic disk is also provided with
    each phantom. The disk is used to establish and monitor a density
    difference with respect to your facility’s operating level. It
    should be placed on top of the phantom in a consistent location
    in the image area so it does not obscure details in the phantom
    and where it can not cast a shadow on any portion of the AEC
    detector. According to the ACR Mammography QC Manual, a
    suitable location is between and slightly below the first and second
    largest fibers.
    Using the Phantom*
    Set Up
    1. Center the phantom on the image receptor surface with the
    nipple indent marker positioned away from the chest wall, just
    as the nipple of the patient’s breast, and the chest wall edge
    of the phantom aligned with the wall side of the image receptor.
    2. Position the x-ray tube and compression device as you would
    for a craniocaudal examination.
    3. Select the mammographic machine settings appropriate for a
    4.2 cm compressed breast. If the phototimer is used, set the
    phototimer to the center position under the wax portion of the
    phantom.
    4. Make an exposure. Process the film. If using a digital mammographic
    system, follow the manufacturer’s image processing
    and display requirements.
    Image Evaluation
    The 156 Map conforms to the requirements of the American
    College of Radiology for use in the ACR Accreditation Program.
    The Phantom may be used to evaluate both screen/film and digital
    images. ** Facilities participating in the ACR Accreditation
    Program will use and evaluate the phantom images in accordance
    with that program. Facilities following other national or
    regional guidelines should refer to those standards.
    1. Background optical should be greater than 1.40 O.D. for
    screen/film images. The density difference between the
    acrylic disk and the background should be at least 0.4.
    Once the density difference is established as an operat
    ing level, subsequent density difference measurements
    should be within +/- 0.05 O.D.
    2. The target mean glandular dose required to achieve the
    optical density is as tabulated in the ACR Mammography
    Quality Assurance manual for different anode/filter com
    binations. Your alternative national or regional stan
    dards.
    3. Phantom images should be read under optimal condi
    tions. Use of a X2 or greater magnifying glass or digital
    image manipulation tools is recommended. Viewbox
    luminance an ambient light levels should be optimized.
    4. The ACR requires that the reader must be able to see all
    of the 0.75 mm fiber, all of the 0.75 mm mass and all six
    of the 0.32 mm specks. As many systems can surpass
    this minimum, attention to degradation over time is as
    important as meeting the minimum requirement.
    Failure to meet the minimum image quality requirements set
    either internally or by your accreditation or regulatory agency
    should prompt investigation and corrective action.
    You should consult with a medical physicist or engineer who
    specializes in mammography and/or diagnostic radiology.
    Following the correction, the system should be retested and the
    new results documented.
    *This manual provides a recommended use of the 156 phantom for routine
    quality assurance in addition to, or in lieu of any other program.
    **At the time of this writing, testing of the full field digital mammography systems
    in the United States must follow the manufacturer’s quality control
    manual.
