Foreword

Nuclear medicine practitioners use solid, uniformly radioactive sources that are several millimeters thick with areas up to 0.25 m 2 (called "flood" sources) to characterize and correct the extrinsic flood field uniformity of scintillation cameras for purposes of both quality assurance and on-line operational corrections. These radioactive sources are intended to produce a uniform radiation field across the camera's usable field of view. Methods to evaluate camera uniformity are described in NEMA NU 1-1994. 1

A broad range of flood sources is available in many sizes and configurations from a number of manufacturers. Such diversity suggests the need for a uniform means of reporting calibration data and a common understanding of the parameters reported. This information can permit intercomparison of sources and give practitioners a means to determine whether a particular source is appropriate for a given task.

Scope

The scope of this standard is limited to commercially-produced, solid radioactive flood sources intended to aid in the determination of the system field uniformity of scintillation cameras used in nuclear medicine.

This standard is intended to provide a set of minimum informational requirements for a Test and Measurement Report for flood sources used with scintillation cameras. It is not intended to specify the means by which such information is obtained, although it does place requirements and limitations on the methodology. In addition, it is not intended to cover the use of the source in the determination of the operating characteristics or correction factors for a scintillation camera.
