9" Image Intensifier with Lens and Camera

 

MAXIvision™ XRD Flat Panel Detector

In combination with powerful software like MAXIenhance™, flat panels generate excellent images for x-ray inspection and are widely used in industrial radioscopy.

We offer flat panels with digital resolutions between 12 and 16 bit, pixel size (pitch) from 50μm to 400 μm and energy ranges between 40keV and 15 MeV. There are static (up to 7.5 fps) and real-time (25 or 30 fps) flat panel models available. Please ask for more information.

Amorphous Selenium Flat panels 

These panels use an amorphous selenium-coated, thin-film transistor (TFT) array to capture and convert X-ray energy directly into digital signals without the use of scintillators or phosphor. Because of the absence of scattering and the optimal signal-to-noise ratio, the image quality approaches the quality of medium-grain film. 

The limitation of a Se detector is the narrow temperature range requested by the Amorphous Selenium. Either in operation or in storage/transport conditions, the detector needs to remain within a temperature range between 5°C and 30 °C, in order to avoid destruction of the Selenium layer

Amorphous Silicon Flat panels 

Amorphous silicon (aSi) flat panels use a scintillator, consisting of cesium iodide or gadolinium oxusulfide, which converts incident x-rays into visible light. This light is converted into an electrical charge by an array of amorphous silicon sensors. The recent progress of the technology, together with software tools that allow averaging multiple frames, the signal-to-noise ratio improved in such a way, that the aSi panel's image quality exceeds that of CR systems and approaches that of aSe detectors. 

Forget conventional radiography! Forget film, chemicals, developing, and waiting for results! MAXIvision™ Segment digital linescan x-ray camera has been developed especially for the operation in digital x-ray inspection. This camera has much better resolution than Linear Diode Array’s (LDA’s) and operation at energy up to 450 kV is no problem. 

The camera’s 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 pixel binning (=> electronic grouping of neighboring pixels to one pixel) enables a variable resolution from 83 µm to 1.3 mm. As the pixel binning 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 to 80m/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 grey levels. 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). 

Specifications:

Forget conventional radiography! Forget film, chemicals, developing, and waiting for results! Now high quality digital x-ray images are possible using this revolutionary new technology.  All custom made scanners (up to 36" in length and 24" in width) offer high resolution and wide dynamic range simultaneously. It works with constant potential X-ray sources. Image is acquired in seconds, then instantly presented on the large flat-panel monitor and saved it on CD that costs 10 cents only.
