Title: (EN) High efficiency computed tomography
(ZH) 图像重建系统、方法和设备
Abstract: front page image
(EN) A system includes transmitters to transmit excitation energy into an object under observation, detectors to generate projection space data encoding energy received in response to the transmitted excitation energy into the object, a controller to control the transmitters to and the receivers to generate the projection space data, an image reconstructor to receive the projection space data, process the projection space data by computing a first quantity characterizing a difference between the projection space data and predicted projection data, computing a second quantity corresponding to at least one impulse response, each impulse response corresponding to a reference voxel of unit-intensity, computing an update value using the first quantity and an inverted function of the second quantity, and reconstructing an object space image representing the object under observation using the update value.
(ZH)

一种系统,包括发射器,用于将激发能射入观察的对象;检测器,用于响应于射入对象的激发能来生成对接收的能量进行编码的投影空间数据;控制器,用于控制发射器并控制接收器生成投影空间数据;图像重建器,用于接收投影空间数据并如下处理所述投影空间数据:计算表征投影空间数据与预测投影数据之间的差的第一量;计算对应于至少一个脉冲响应的第二量,每个脉冲响应对应于单位强度的参考体素;使用第二量的逆函数和第一量计算更新值;以及使用所述更新值重建表示观察的对象的对象空间图像。
