摘要： The technical solution as put forth by the present invention comprises a computer imaging system and detectors arranged around the detected object for collecting gamma photons from positron annihilation events. The key is a multi-pinhole plate placed between the detected object and the detectors, and the multi-pinhole plate can be a coded aperture mask coded by using a function h(x,y). The gamma photons generated from the annihilation events inside the detected object are absorbed by the detector after being collimated by the multi-pinhole plate. Accordingly, after the detectors have performed detection at multiple angles, the result is transmitted to the computer imaging system, and quasi three-dimensional images are generated after being processed by the disclosed algorithm. Furthermore, the quasi three-dimensional images generate secondary projection images and, after adjustment, generate sinograms, and finally three-dimensional tomographic images are reconstructed from multiple sinograms.
摘要翻译：本发明提出的技术方案包括计算机成像系统和围绕检测对象布置的检测器，用于从正电子湮灭事件收集伽马光子。关键是放置在被检测物体和检测器之间的多针孔板，并且多针孔板可以是通过使用函数h（x，y）编码的编码孔径掩模。由检测对象内的湮灭事件产生的伽马光子被多针孔板准直后被检测器吸收。因此，在检测器以多个角度进行检测之后，结果被传送到计算机成像系统，并且在通过所公开的算法处理之后产生准三维图像。此外，准三维图像产生二次投影图像，并且在调整之后生成正弦图，最后通过多个正弦图重建三维断层图像。

摘要： Disclosed is a collimating apparatus for emission tomography. The collimating apparatus comprises a perforated plate (1) that is disposed between a detector (2) and a to-be-detected object and provided with a plurality of through holes (5); wherein a minimum distance between central points of each two adjacent through holes (5) is t, and a distance from the central point of the through hole (5) to the wall of the through hole (5) is half of Φ, where t>Φ>t/2. The perforated plate (1) comprised in the collimating apparatus addresses problems of both the stability of portions surrounding the through holes (5) and the aperture ratio of the perforated plate (1), and ensures sensitivity of the detector (2).

摘要： A method includes receiving a first set of 2D images of an object, wherein the first set of 2D images is derived from a three-dimensional (3D) image of the object placed at a first pose. The method further includes generating a set of bound 2D images by binding multiple 2D images of the first set, wherein the multiple 2D images correspond to adjacent sub-volumes of the 3D image. The method further includes projecting the set of bound 2D images from the first pose to a second pose different from the first pose, thereby obtaining re-projected 2D images. The method further includes combining the re-projected 2D images.
