X-ray detector and method for tissue specific imaging

摘要: A method (200, 300) for energy dependent imaging of a region interest includes the step exposing (204) and X-ray detector to photons during an examination period, separating (206, 208) into two groups, those with energies above selected threshold, below threshold. The threshold are counted (304) provide first photon count, while (306) second count. stores (210) count in memory as data, produces (212) image by applying processing technique data.
