Linescan X-Ray

Product introduction

General Principle

The digital linescan x-ray cameras of the SEZ series have been developed by NTB especially for the operation in digital x-ray inspection. The x-ray camera is the result of an intensive research in the field of digital x-ray technology. A continuous further development of the SEZ-T3 and the SEZ-W line suits the cameras for the use in most different applications and requirements.

A robust construction for operations from 20 kV up to 450 kV guarantees a long life time and resistance against mechanical strain. The slit collimators of the cameras make them highly insensitive to scattered rays. The hardware pixelbinning (=> electronic grouping of neighboring pixels to one pixel) enables a variable resolution from 83 µm to1.3 mm. As the pixelbinning is freely adjustable, it is possible to realize applications which require a very high resolution as well as applications with very high scanning speeds (up to80m/min) with one and the same camera system.

The high dynamic range (12 bit A/D conversion) supplies x-ray images with up to 4096 greylevels. The x-ray images can be evaluated, processed, archived, transmitted or used for documentations. It is possible to integrate the camera system into third-party software by the use of the supplied software library (DLL). Thereby, custom specific solutions up to the fully automatic acquisition and evaluation of the x-ray images become possible.

The digital x-ray cameras are highly economic and future-oriented: There are no overhead costs for film, chemicals and film processing. The archiving of all data is space saving, as many x-ray images can be saved on one small data medium (hard disk / CD / DVD).

The linear x-ray camera can be integrated as a digital extension in already existing x-ray units or can be supplied as complete x-ray system.

Funtional Principle

The outstanding performance of the NTB digital linear x-ray camera is achieved by the use of the unique and revolutionary x-ray sensitive detector developed by NTB. A scanning operation, in which either the specimen (2) or the camera (1) plus x-ray source (4) are progressively advanced, generates a 2D image line by line (object length determines the scanning distance). During the scanning process ultra fast A/D converters digitize the detector signals and generate a 12 bit (=4096 greylevels) image on the screen (5).

Compared to regular film based x-ray systems, NTB's digital x-ray cameras have a significant higher dynamic range. Where an x-ray film is totally over- or underexposed, the SEZ cameras still deliver high quality x-ray images. Consequently, objects composed of varied materials or objects with large thickness differences may be scanned in one single process. The x-ray images on the screen can directly be zoomed and enhanced for detailed evaluations or measurements. The scanned images can be archived, incorporated in reports or electronically transmitted.
