DEVICE AND METHOD FOR OBJECT DETECTION, AND COMPUTED TOMOGRAPHY IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To detect an object by means of projection of X-ray passing the object and a detector counting a quantum with optimized contrast and noise. SOLUTION: The detection device includes a transmitter 5 configured for transmitting the quantum 34 and at least one detector 7 disposed on a detection plane 10 for detecting the transmitted quantum 34. The detector is configured and positioned so as to generate at least one detector signal at least partially representing the projected object 40 depending on the quantum 34 passing the object 40 and received. The detection device 1 and 3 are configured to detect the object so as to generate quantum signals representing quantum energy of the detected quantum depending on the detector signals generated for the detected quantum. The detection device is configured to generate adding signals corresponding to total quantum energy of quantum energy represented by the quantum signals. COPYRIGHT: (C)2008,JPO&INPIT
