Problems solved by technology

[0010] However, if the duration of the delay line is less than the duration of the edge leaving the amplifier, telescoping occurs in the subtractor and the measurement of the pulse amplitude greatly underestimates the actual amplitude of the signal edge of the charge amplifier and thus underestimates the actual energy stored by the photon X
Since this amounts to a loss, in this case a fraction of the charge generated by the detector, the signal-to-noise ratio is severely degraded

Embodiment Construction

[0040] figure 1 An X-ray imaging system 10 for baggage inspection is schematically shown. The imaging system 10 comprises an X-ray source 11 , a conveyor belt 12 capable of transporting luggage 13 in the direction indicated by arrow 14 , a semiconductor detector 15 and a processing device 16 connected to the detector 15 . figure 1 The detector 15 shown in is an L-shaped linear detector. The detector comprises elements sensitive to X-rays, such as photodiodes or photoconductors arranged in two mutually perpendicular lines. The detector 15 may also be a two-dimensional detector and comprise a matrix of sensitive elements.

[0041]When the sensitive element of detector 15 is exposed to an X-photon, the sensitive element converts the photon into a packet of charge, the amount of which is proportional to the energy of the photon. The X-ray source 11 emits a flux of photons through the conveyor belt 12 in the direction of the detector 15 . Before the object is analyzed, the spec...

Abstract

The invention relates to a device for spectrometry of a radiation of photons, the device (20) comprising: a detector (15) configured to receive the radiation and to deliver, at an output (24), an electrical signal that is a function of the radiation (X) received, characterized in that the device (20) further comprises: a reference database (42) that can be parameterized by means of a first parameter, a comparator (38) configured to establish a comparison between the electrical signal and the reference signal, the comparator (38) delivering a signal (E(t)) representative of the energy of each photon of the radiation and a quality factor (B(t)) of the comparison, a feedback loop (46, 50, 52) enabling the first parameter of the reference database (42) to be adapted so as to optimize the quality factor (B(t)).

Description

technical field [0001] The present invention is in the field of imaging using ionizing radiation, for example using X or gamma beams. The invention is applicable to medical imaging and non-destructive inspection such as baggage inspection. The invention relates to a device for processing 5 photon fluxes. Background technique [0002] X-ray imaging systems are especially used for baggage inspection at airports or security locations. Such an imaging system includes an X-ray radiation source that subjects the luggage to a flux of X-photons and a semiconductor detector that receives the X-photons passing through the luggage. Based on the luggage's absorption of X-rays, the contents of the luggage can be analyzed. The analysis of the baggage content and the assessment of the danger of this content is more or less complex and the automated steps depend on whether the baggage is carried to the baggage compartment or by cabin passengers. In both cases, the goal of the X-ray imag...
