    Standard Frequency Series Generators Installation SECTION 11 MEASUREMENT BASIS 11.1 MEASUREMENT BASIS The measurement basis to insure accurate technique factors are as follows: Timer radiation sensitive counter at the X-ray Tube port counts pulses. Accuracy is one part in 10,000. Electronic counter DHEW design. Counts primary pulsed accurately to +/- zero pulses.

    This test requires a 300 VAC meter having an accuracy of 1% or better, and of known calibration. Turn on the machine and vary the kVp with the AC meter connected parallel to it. The kVp meter in the TXR 325 D & M, TXR 425 and TXR 525 SFQ X-Ray Control is actually a 300 VAC voltmeter calibrated in kVp. See Load Line Chart for Voltage Settings and kVp meter readouts.

    Standard Frequency Series Generators Installation OIL, INSULATING Type: Diala AX or equal. Cold oil contracts, warm oil expands. Make sure transformer is filled no lower than 1 inch from the top and no closer than inch. Do Not Contaminate Oil by immersing hands into oil. Oil is most of the high voltage insulation. Do not let moisture saturate oil by leaving the cover off the tank or by storing in a cold room then heating repeatedly. This will cause moisture to collect inside the tank.

  • Page 74: Maintenance Schedule For Radiation Safety

    Standard Frequency Series Generators Installation SECTION 13 MAINTENANCE SCHEDULE FOR RADIATION SAFETY OF X-RAY APPARATUS In order to assure continued compliance to the IEC and Federal Performance Standards, maintenance inspections and test should be carried out by qualified personnel on original installation and at intervals of 6 months or less. Specific instructions for performing these maintenance activities are provided by the individual manufacturers. This schedule is a guide that relates to conformance to the IEC and DHHS/FDA Standards and is not intended to assure general equipment performance, which must be carried out independently.

    Standard Frequency Series Generators Installation X-Ray Exposure Switch. Confirm that any switch provided for activating an X-Ray exposure requires continuous pressure to maintain the exposure or that release of the switch terminates the exposure. Warnings and Indicators Legible. Inspect and confirm that all warning labels and embossed, painted, silk screened, or other wearable technique factor indicators have not been defaced or worn so as to be illegible.

Verify presence integrity and functioning of means provided to limit X-Ray field size to not greater than the image receptor, and to align the field and receptor centers to within 2% of S.I.D. Other X-Ray Systems. Verify presence, integrity and functioning of means specified and provided for the certified component to limit the X-Ray field such that each dimension does not exceed image receptor size by more than 2% of S.I.D. and to align the centers of the X-Ray field and receptor to within 2% of S.I.D. Verify presence and visibility of markings identifying image receptor size and S.I.D. Field Limitation and Alignment. (A). Verify that the total misalignment of X-Ray field with the respective edges of the selected portion of the image receptor does not exceed 3% of S.I.D. for length or width, nor 4% of magnitudes for the two directions. (B). Verify that X-Ray field size can be adjusted smaller than the selected portion of the film, and that at maximum S.I.D. a field size of less than 5 x 5 cm. can be provided. (C). Verify that the centers of the X-Ray and selected film portion coincide within 2% of S.I.D. (D). Perform manufacturers routine maintenance. Source Skin Distance Verify the presence and integrity of the means specified and provided for the certified component to limit source skin distance to no less than 45 cm.
