Foreword
GB/T 23909 "NDT-ray transmission detector" is divided into three parts.
--- Part 1. Quantitative measurement of imaging performance;
--- Part 2. Long-term stability of the imaging device calibration;
--- Part 3. metallic materials by X - and gamma rays detected General.
This is Part 2 GB/T 23909 of.

Introduction
This section GB/T 23909 gives control of the quality of the imaging device during operation outline. GB/T 23909.1 given set
Advised by an imaging system and a part of typical defects to identify critical defects and the ability to test the resistance ray fluoroscopy system
can. In addition to standard image quality indicator can be used day and the hardest to identify those with the smallest sample as a natural defect overall system performance
Regular quality control.
4 with IQI Image Quality Control
4.1 Overview
Ray fluoroscopic image quality is substantially determined by the sharpness, contrast and linearity.
Parameters in GB/T 23909.1 described depends on the radiation source, arranged imaging systems and sample. For quality control, should be in operation
All performance regularly detected ray fluoroscopy device to assess these arguments, and in normal operation should use the same operating system.
You can use IQI.
All samples, if possible, IQI must be placed in a sample-ray source toward that side.
For a particular sample, if there is GB/T 23909 of the other part, it should be used in the quality control.
