Subchapter 11 - Use of X-Rays in the Healing Arts and Veterinary Medicine
Section 310:281-11-17 - Veterinary x-ray systems
Universal Citation: OK Admin Code 310:281-11-17
Current through Vol. 42, No. 1, September 16, 2024
(a) Systems.
(1) The system shall
display the selected exposure factors before the exposure begins.
(A) The requirement of 310:281-11-17(a)(1)(A)
may be met by permanent markings on equipment having fixed technique factors.
Indication of technique factors shall be visible from the operator's position
except in the case of spot films made by the fluoroscopist.
(B) The x-ray control shall provide visual
indication of the production of x-rays observable at or from the operator's
protected position whenever x-rays are produced.
(2) The leakage radiation from the diagnostic
tube head assembly measured at a distance of 1 meter in any direction from the
source shall not exceed 100 milliroentgens in 1 hour when the x-ray tube is
operated at its leakage technique factors. Measurement is averaged over an area
of 100 square centimeters with no linear dimension greater than 20 centimeters.
(3) The useful beam shall be
restricted to the area of clinical interest and no larger than the size of the
image receptor.
(4) Collimating
devices shall be provided and shall limit the beam to the area of the image
receptor to within 2 percent of the SID, and shall provide the same degree of
protection as is required of the housing.
(5) The half-value layer of the useful beam
shall not be less than 0.5 millimeter aluminum equivalent for systems operating
up to 50 kVp, 1.5 millimeters aluminum equivalent for systems operating between
50 and 70 kVp, and 2 millimeters aluminum equivalent for systems operating
above 70 kVp.
(6) A device shall be
provided to terminate the exposure after a preset time or exposure.
(7) A dead-man type of exposure switch shall
be provided, together with an exposure control cord of sufficient length, so
that the operator can stand out of the useful beam and at least 6 feet from the
animal during all x-ray exposures.
(8) The coefficient of variation for exposure
shall not exceed 0.10 when all technique factors are held constant. This
requirement is met when 4 exposures are made at identical technique factors,
the value of the average exposure (E) is greater than or equal to 5 times the
maximum exposure (E max) minus the minimum exposure (E min): E
> 5(E max - E
min)
(9) The primary beam shall be
aligned with the film by using specified technique in the facility's operating
procedures.
(10) Fluoroscopic and
CT systems used in veterinary facilities shall meet the requirements of
310:281-11-13
and
310:281-11-15
respectively, except the aural communications requirements of
310:281-11-15(b)(1).
(11) Portable systems shall be used in a
manner which complies with these rules.
(b) X-ray control location. Each x-ray control shall be located in such a way as to permit the operator to remain in an area of less than 2 millirems in any 1 hour during the entire exposure.
