Current through Register Vol. 48, No. 39, March 25, 2024
Subpart
1.
Required standards.
The following procedures and auxiliary equipment designed to
minimize patient and personnel exposure must be used.
A. The speed of screen-film combinations, or
direct exposure x-ray film in intraoral dental radiography, must be the fastest
speed consistent with the diagnostic objective of the examinations.
B. Except for dental intraoral films and
radiation therapy port films, intensifying screens must be used in combination
with the compatible film.
C. The
radiation exposure to the patient must be the minimum exposure required to
produce images of good diagnostic quality utilizing the ALARA
concept.
D. Portable x-ray
equipment must be used only for examinations where it is impractical to
transfer the patient to a stationary x-ray system.
E. Other than fluoroscopic and dental
intraoral systems, radiographic systems must not be used in procedures where
the source-to-skin distance is less than 11.8 inches (30 centimeters), except
as described in part
4732.0825.
F. Personal protective garments must be
monitored for integrity initially and at intervals not to exceed 24
months.
G. The registrant must
maintain the record of the monitoring and evaluation including films if
applicable, according to part
4732.0330.
Subp. 2.
Radiographic technique
chart.
A radiographic technique chart must be provided in the
vicinity of the x-ray system's control panel.
A. The technique chart must specify the
following information for all examinations:
(1) the technique factors to be used for
anatomical parts and patient size;
(2) the type of screen, type of film, and
speed combination to be used;
(3)
the source-to-image distance to be used;
(4) for automatic exposure control (AEC) or
phototimed units, the percent differences between the AEC increments.
B. For computed tomography
systems, a current technique chart for each routine examination and the
computed tomography conditions of operation must be provided.
C. For filmless radiography, including
computed radiography, digital radiography, computed tomography systems, and
photostimulable storage phosphor imaging, the technique chart must reflect the
adult and pediatric technique parameters for the individual system. This
includes the manufacturer's requirements for technique parameters.
Subp. 3.
Exceptions.
Diagnostic radiation-producing equipment manufactured with
anatomical programming and industrial facilities with radiation-producing
equipment are exempt from subpart
2.
Subp. 4.
Records.
Records must be maintained according to part
4732.0330.
