Abstract
Official abstract text for this publication.
The invention relates to a method for radiation detection signal processing, and more particularly to a method capable of using a periodic signal to control the time of charging/discharging to a capacitor of an integrator. The method can be used for detecting the energy of incident photon of Gamma ray during the happening of an event while reducing dead time, and thereby, the count rate is increased. As the periodic signal is used as the signal for controlling the time of charging/discharging to a capacitor, the charging/discharging time of the integrator is no longer being controlled by the triggering time of the event, and thus, the present method is advantageous in that: the control method and circuit architecture are comparatively simpler since the charging/discharging time of the integrator no longer required to be controlled precisely, and thus the integration error due to insufficient resolution in delay element can be avoided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for radiation detection signal processing, comprising the steps of: (a) using a probe of an instrument to detect ionizing radiation; (b) using a photoelectric conversion device in the probe to convert the emitted ionizing radiation into at least one electric signal; (c) feeding the at least one electric signal to at least two integrators simultaneously for integration while enabling a control unit to issue at least two periodic signals of compat…
