Section 459.618 - General purpose X-ray systems: Stationary and mobile

Universal Citation: NV Admin Code 459.618

Current through December 31, 2024

1. A means must be provided for stepless adjustment of the size of the X-ray field.

2. A means must be provided for visually defining the perimeter of the X-ray field. The total misalignment of the edges of the visually defined field with the respective edges of the X-ray field along either the length or width of the visually defined field must not exceed 2 percent of the distance from the source to the center of the visually defined field when the surface upon which it appears is perpendicular to the axis of the X-ray beam.

3. The Division may grant an exemption from subsections 1 and 2 for an uncertified X-ray system if the registrant makes a written application for the exemption and in his or her application demonstrates that:

(a) It is impractical to comply with subsections 1 and 2; and

(b) The purpose of NAC 459.400 to 459.624, inclusive, and section 28 will be met by other means.

4. All stationary general purpose X-ray systems must meet the following additional requirements:

(a) The beam-limiting device must numerically indicate the field size in the plane of the image receptor to which it is adjusted;

(b) Indication of field size dimensions and source-image receptor distances must be specified in inches or centimeters, or both, and must be such that aperture adjustments result in X-ray field dimensions in the plane of the image receptor which correspond to those of the image receptor to within 2 percent of the source-image receptor distance when the beam axis is perpendicular to the plane of the image receptor; and

(c) A means must be provided to indicate when the axis of the X-ray beam is perpendicular to the plane of the image receptor, to align the center X-ray field with respect to the center of the image receptor to within 2 percent of the source-image receptor distance, and to indicate the source-image receptor distance to within 2 percent.

5. Radiographic equipment designed for only one image receptor size at a fixed source-image receptor distance must be provided with means to limit the field at the plane of the image receptor to dimensions no greater than those of the image receptor, and to align the center of the X-ray field with the center of the image receptor to within 2 percent of the source-image receptor distance.

6. All radiographic equipment must:

(a) Only be used for its designed purpose, as specified by the manufacturer; and

(b) Be maintained and serviced in accordance with the manufacturer's recommendations unless there is a documented change to the maintenance and service requirements by the manufacturer or the radiographic equipment is certified and labeled in accordance with 21 C.F.R. §§ 1010.1 to 1010.5, inclusive, and 1020.31.
