This product has been tested by Underwriter’s Laboratories in conformance with standards set forth by UL 2601-1, CAN/CSA-C22.2 No. 601.1-M-90, and IEC 601-2-32. It has been found to comply with these standards and, therefore, bears the above “Recognized Component” symbol for UL and UL-C. UL File No.
Figure 1.1 • • • November 2005 1.0 INTRODUCTION MANUAL OPERATION Press the “lamp” pushbutton to activate the light-field. Adjust the shutters (both longitudinal and cross) to a size not larger than the film to be used. Center light-field over cassette or anatomical area to be exposed.
This manual contains information for the assembly, installation, adjustment, testing and maintenance of the LINEAR series of radiographic/fluoroscopic collimators manufactured by Progeny, Inc. 1.1 YOU HAVE LEGAL OBLIGATIONS The manufacturers of beam limiting devices are required to provide instructions for the assembly, installation, adjustment and testing adequate to assure compliance with applicable provisions of DHHS Performance Standards 21 CFR Sub-Chapter J, Part 1020.
The landing area of the beam will contain a radiographic image receptor located in a plane perpendicular to the beam at pre-determined distances from the radiation source (focal spot). The size and shape of the image receptor will determine the maximum useful crosssectional size and shape of the beam in the plane of the image receptor. The source-toimage receptor distance (SID) determines the actual shutter opening required to regulate the beam size and shape in the plane of the image receptor. 1.
1.5 ADVANCED FEATURES The Linear MC150-C Collimator system also incorporates features required for diagnostic convenience... 1.6 … Swivel mount standard for angulated positioning. … All electronic components are standardized types available at major electronic suppliers. Use of standardized, straight-forward logic allows troubleshooting and repair with general electronic experience. … A spare lamp is provided inside the lamp housing and is easily replaced by the owner/operator.
Mechanical-Electrical Warning for Diagnostic X-Ray Systems All of the moveable assemblies and parts of X-Ray equipment should be operated with care. Only properly trained and qualified personnel should be permitted access to any internal parts. Live electrical terminals are deadly; be sure line disconnect switches are opened and other appropriate precautions are taken before opening access doors, removing enclosure panels, or attaching accessories.
3. Inherent Filtration and Half-Value Layer: The Eureka Linear™ collimator has a minimum value of 2.0 mm aluminum equivalence at 100 kV. This value plus any tube inherent filtration plus any added filtration must meet the minimum requirements of 21 CFR Sub-Chapter J, Part 1020.30 (m)(1) Table 1 on beam quality (e.g. minimum HVL at 100 kV must be 2.7 mm Al. 4. Application: The intended application is for general purpose radiographic equipment, including tomographic and chest applications.

There is also a fixed aperture cone which protrudes into the port of the X-Ray tube that helps reduce the effects of offfocus radiation.
with these knobs. Scales provided on a deadfront panel indicate all conventional film sizes for both 40”, 72”, 100 cm and 180 cm SID’s. All Eureka Linear Series collimators have a swivel mount configuration. Detents are located at 90 degree increments. The collimator may be oriented to any position for achieving proper X-Ray field to cassette alignment for table-top or non-bucky operation. The shutter mechanism has been precisely aligned with respect to the mounting flange at the factory.
