HIGH FLUX PHOTON COUNTING DETECTOR ELECTRONICS |
摘要 |
An imaging system (100) includes a radiation source (108) that emits radiation that traverses an examination region, a paralyzable photon counting detector pixel (110) that detects photons traversing the examination region and arriving at an input photon rate and that generates a signal indicative thereof, high flux electronics (122) that produce a total time over threshold value each integration period based on the signal, a reconstruction parameter identifier (124) that estimates the input photon rate based on the total time over threshold value and identifies a reconstruction parameter based on the estimate, and a reconstructor (130) that reconstructs the signal based on the identified reconstruction parameter. |

1. An imaging system, comprising:
a radiation source that emits radiation that traverses an examination region; a paralyzable photon counting detector that detects photons traversing the examination region and arriving at an input photon rate and that generates a signal indicative thereof; high flux electronics that produce a total time over threshold value each integration period based on the signal; a reconstruction parameter identifier that estimates the input photon rate based on the total time over threshold value and identifies a reconstruction parameter based on the estimate; and a reconstructor that reconstructs the signal based on the identified reconstruction parameter. |
