Review of X-ray detection systems

Urbański Paweł, Grzebyk Tomasz

Opto-Electronics Review

2023

Vol. 31, No. 3

art. no. e146554

The article presents an overview and a classification of X-ray detection methods. The main motivation for its preparation was the need to select a suitable and useful method for detecting signals from a currently developed miniature micro-electro-mechanical system (MEMS) X-ray source. The described methods were divided into passive and active ones, among which can be distinguished: chemical, luminescent, thermo-luminescent, gas ionization, semiconductor, and calorimetric methods. The advantages and drawbacks of each method were underlined, as well as their usefulness for the characterisation of the miniature MEMS X-ray source.

Efficiency analysis and promising applications of silicon drift detectors

Khreptak Aleksander, Skurzok Magdalena

Bio-Algorithms and Med-Systems

2023

Vol. 19, no. 1

74--79

Silicon drift detectors (SDDs) stand as a groundbreaking technology with a diverse range of applications, particularly in the fields of physics and medical imaging. This paper provides an analysis of the performance of SDDs as detectors for X-ray radiation measurement, shedding light on their exceptional capabilities and potential in medical imaging. Compared to conventional detectors, SDDs have several notable advantages. Their high efficiency in capturing X-rays allows them to provide outstanding sensitivity and accuracy in detecting even low-energy X-rays. In addition, SDDs exhibit significantly low electronic-noise levels, contributing to better signal-to-noise ratio and better data quality. Furthermore, their high resolution enables exact spatial localization of radiation sources, which is essential for accurate diagnosis. This research is devoted to the evaluation of efficiency and potential application of SDDs in X-ray spectroscopy, with particular emphasis on their application in medical imaging. We focus on evaluating the performance characteristics of SDDs, such as their linearity, stability and sensitivity in detecting X-rays. The aim is to highlight the suitability of SDDs for a wide range of applications.

Problemy korekcji w hybrydowych pikselowych detektorach promieniowania X

Drozd A., Maj P.

Przegląd Elektrotechniczny

2014

R. 90, nr 5

86--89

Promieniowanie X jest szeroko stosowane w medycynie w klasycznej rentgenografii, rentgenowskiej tomografii komputerowej, czy w badaniach materiałowych. Do badań diagnostycznych coraz częściej wykorzystuje się detektory promieniowania X pracujące w trybie pojedynczego zliczania fotonów, które pozwalają na rejestrację i przetwarzanie każdego wpadającego do piksela impulsu z osobna, a przez to zwiększenie kontrastu obrazowania. Artykuł prezentuje przegląd problemów niejednorodności w obrazowaniu przy użyciu takich pikselowych detektorów promieniowania X, a także metody ich korekcji.

X-ray imaging is widely used in medicine in classic radiography, X-ray computed tomography and structural characterization of materials. X-ray detectors working in single photon counting mode, which register and process each photon separately, become more and more popular due to the possibility of imaging contrast enhancement. This paper presents problems of nonuniformity in imaging using this type of pixel X-ray detectors and methods of its correction.
