GB/T 30821-2014Non-destructive testing -- Practice for digital imaging and communication (English PDF)

GB/T 30821-2014 is the English-translated version of 无损检测 数字图像处理与通信.

GB/T 30821-2014 — 1.1 standard between devices via generic term standardized image data file formats, improved non-destructive testing (NDE) imaging and data acquisition Interoperability.

This standard enables NDE imaging system or modality and the National Electrical Manufacturers Association (NEMA) Standards Publication "Medical collar Field of digital image processing and communication "(DICOM) standard consistent.

"Medical field of digital image processing and communication" (DICOM) is a Specifications for image data acquisition, evaluation, storage and archiving of international standards.

In addition, the standard also specifies a set of industrial NDE special letter Interest defined object, its definition is outside the scope of the DICOM Standard modes.

This standard specifies the digits in all areas to meet the NDE NDE image/signal data displayed on the image processing and communication (DICONDE) format system, the method of obtaining data NDE modality irrelevant.

1.2 standard solves the problem with a different NDE technology acquisition of data generated in the process of archiving or analysis, each of NDE techniques Using a unique data acquisition system.

With the development of modal data acquisition technology, the data obtained in the past to keep still encoding translation. This standard provides an image data file format, which all the technical parameters and image files remain together, without NDE the impact of technological change.

In addition, different types of images (CT, CR, ultrasound, infrared and vortex) can also work through this in a standard View station, and at the same time retain the relevant technical parameters of these image files.

In addition, the standard contributes to the digital information in different Exchange NDE image processing devices. 1.3 This standard does not apply to the following.

1.3.1 assess the actual operation of the application meets this standard testing or certification procedures. 1.3.2 a specific device and application of practical details of the device meets the requirements.

1.3.3 whether by a group of devices (each device shall meet the requirements of DICONDE or DICOM) integrated system can achieve the desired overall Performance features and functionality.

1.4 Although this standard does not include the value of the unit, but the method used for data storage and communications but need to add the unit in order to say Bright.

SI is the standard unit of measurement of this standard, other units of measurement do not meet this standard.
