TEST TOOL, AEC For performing quick checks of automatic exposure control. Performance capability refers to the ability of an AEC (Automatic Exposure Control) system to maintain a constant optical density over a broad range of imaging techniques and patient variables. The AEC Test Tool is designed to assess the ability of a given radiographic system to achieve this goal, as well as to determine the range of conditions over which the system will not perform adequately. More specifically, this high-quality test tool allows the user to assess the performance of the radiographic unit's automatic exposure control system, with regard to performance capability and density control selector function. An automatic exposure control system with appropriate compensation circuits is functioning properly if it can maintain constant film optical density. The AEC Test Tool provides a means by which one can vary the thickness of attenuation material to simulate different patient thicknesses. The AEC Test Tool consists of a set of four acrylic sheets, each 25 cm x 25 cm x 5.08 cm thick. By placing varying thicknesses of acrylic in front of the photocells, and imaging under clinical conditions, the test films will show the AEC system's capability to produce constant and uniformly-exposed radiographs. Nuclear Associates' AEC Test Tool provides an easy and inexpensive way to determine the performance of all radiographic phototiming systems. There is no need to go into the generator circuity to evaluate the system. By using the AEC Test Tool in conjunction with film, a quick determination of the AEC capability can be made. SPECIFICATIONS: Test Tool Material: Acrylic Dimensions (each sheet): 25 cm x 25 cm x 5.08 cm thick Weight per sheet: (3.2 lbs) 1500 g |
