X-Ray Image Acquisition with a Gaseous Detector

In a laboratory session, it is shown that an X-Ray position sensitive detec-tor based on the multi-wire proportional counter design is an effective device for acquiring images produced by ionizing particles. The analog and digital electronics modules required to operate the detector are presented to the stu-dents, along with a description of their working principles. Finally, the data acquisition software and its capabilities are demonstrated, so that the complete detection chain is available and the students may face the main goal, which is: obtaining good quality X-Ray images. In this chapter, we briefly describe the hardware and the software, and report on the procedures required to obtain the best quality raw data for the given experimental setup. We concentrate on two techniques for image quality improvement. One of these is the correction for non-uniformities of the detector response over the active detecting window, and the other one is the application of a de-convolution algorithm used as an off-line tool to improve the image quality
