4.1 The X-, gamma-ray detector discussed in this practice is a storage phosphor imaging plate, hereafter referred to as SPIP. The SPIP, which is the key component in the CR process, differentiates CR from other radiologic methods. This practice is written so that it can be specified on the engineering drawing, specification, or contract and must be supplemented by a detailed procedure (see Section 6 and Annex A1 and Annex A2).

1.1 This practice² covers application details for computed radiology (CR) examination using a process in which photostimulable luminescence is emitted by the penetrating radiation detector, a storage phosphor imaging plate (SPIP). Because the techniques involved and the applications for CR examination are diverse, this practice is not intended to be limiting or restrictive, but rather to address the general applications of the technology and thereby facilitate its use. Refer to Guides E94 and E2007, Terminology E1316, and Practices E747 and E1025, and 21 CFR 1020.40 and 29 CFR 1910.96 for additional information and guidance.

1.2 The general principles discussed in this practice apply broadly to penetrating radiation CR systems. However, this document is written specifically for use with X-ray and gamma-ray systems. Other CR systems, such as those employing neutrons, will involve equipment and application details unique to such systems.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific safety statements, see Section 10 and 21 CFR 1020.40 and 29 CFR 1910.96.
