APPARATUS AND METHOD FOR PILE-UP CORRECTION IN PHOTON-COUNTING DETECTOR |
| 摘要 |
Some embodiments are associated with an input signal comprising a first and a second photon event incident on a photon-counting semiconductor detector. A relatively slow charge collection shaping amplifier may receive the input signal and output an indication of a total amount of energy associated with the superposition of the first and second events. A relatively fast charge collection shaping amplifier may receive the input signal and output an indication that is used to allocate a first portion of the total amount of energy to the first event and a second portion of the total amount of energy to the second event. |

1. A system, comprising:
a detection system to receive an input signal associated with a first and a second event in a photon-counting semiconductor detector; a relatively slow charge collection shaping amplifier to receive the input signal and to output an indication of a total amount of energy associated with the combined first and second events; and a relatively fast charge collection shaping amplifier to receive the input signal and to output an indication that is used to allocate a first portion of the total amount of energy to the first event and a second portion of the total amount of energy to the second event. |
