Title:
放射線データを取得する検出器およびシステム
Document Type and Number:
Japanese Patent JP4904349
Kind Code:
B2
Abstract:
Method and apparatus for sensing and acquiring radiation data comprises sensing radiation events with a multi-modality detector. The detector comprises solid state crystals forming a matrix of pixels which may be arranged in rows and columns, and has a radiation detection field for sensing radiation events. The radiation events for each pixel are counted by an electronic module attached to each pixel. The electronic module comprises a threshold analyzer for analyzing the radiation events. The threshold analyzer identifies valid events by comparing an energy level associated with the radiation event to a predetermined threshold. The electronic module further comprises at least a first counter for counting the valid events.
