The role of the false events on the DQE measurement of the radiation detectors

TL;DR

This paper investigates how false events impact the measurement of detective quantum efficiency (DQE) in radiation detectors, considering both counting and imaging detectors, to improve understanding of detector performance.

Contribution

It provides an analysis of the influence of false events on DQE measurement, a factor often overlooked in radiation detector evaluation.

Findings

False events significantly affect DQE measurements.

The analysis applies to both counting and imaging detectors.

Results help improve detector calibration and performance assessment.

Abstract

The efficiency of a radiation detector, intended as probability of detection of an incident quantum, depends on various factors: the detected fraction of quanta ascribed to the noise-less detector, the intrinsic noise of the detector, the false events introduced by the detection process and the false events generated by the detector itself. In this paper is treated the role of the false events on the measurement of the detective quantum efficiency (DQE) of the radiation detectors, indifferently for counting detectors and imaging detectors.
