PHOTON COUNTING IMAGE DETECTOR, X-RAY DIAGNOSIS APPARATUS, AND X-RAY COMPUTERIZED TOMOGRAPHY APPARATUS |
摘要 |
<p>A photon counting type image detector has: a semiconductor cell that detects an X-ray photon; a charge amplifier that generates a plurality of electric pulses each being based on an electric charge collected in response to the detected X-ray photon; a comparator that discriminates a peak value of each of the electric pulses; a threshold logic circuit that performs control so as to count none of the peak-discriminated electric pulses corresponding to energy of characteristic X-rays produced in the semiconductor cell; and a counter that counts the discriminated electric pulses as controlled by the threshold logic circuit.</p> |
