摘要: Plural camera heads are each placed in a position capable of detection of radiation emitted from a radiation source. Compton cones obtained from the detection data output from each of the plural camera heads are projected onto three-dimensional space and an image based on the radiation source is reconstructed. In addition, projected images from projecting Compton cones obtained from the detection data output from each camera head onto two-dimensional planes are also employed for determining a three-dimensional space excluding regions where the radiation source is not present. Reconstruction of images based on the radiation source is then performed within the determined three-dimensional space.
摘要翻译: 多个相机头每个放置在能够检测从辐射源发射的辐射的位置。 从多个相机头中的每一个输出的检测数据获得的康普顿锥被投影到三维空间上,并重建基于辐射源的图像。 此外,从每个相机头输出的检测数据获得的投影康普顿锥的投影图像也被用于确定不存在辐射源的区域之外的三维空间。 然后在确定的三维空间内执行基于辐射源的图像的重建。
