On the basement of conventional direct fan-beam reconstruction, this paper gives a newly improved algorithm-"fast filtering-backprojection". This method utilizes the symmetrical circle geometry to sample projection data, and reconstructs image on the Polarcoordinate firstly, then translates this reconstructed image onto the cartesian coordinate system with two interpolating operations so that the computer can show the result image on the VGA screen. This algorithm rebates the calculating backprojection greatly, and shortens a few times of reconstructing time than same kinds of means. With the size of image enlarging, the reconstructing time abates with 2 exponent times. In addition, according to the idea of parallel-beam, we rearrange the fan-beams and reconstruct image using parallel-beam method fastly. The rearranging constraint condition is given here.

本文首先在传统的扇束直接重建方法的基础上,提出了一个改进的快速滤波反投影重建算法,它利用旋转采集投影数据的圆周对称的几何关系,先在极坐标系统内进行图象的重建,然后通过两次内插运算再将图象转换到计算机显示方式下的笛卡尔坐标系中去,该方法将以往的直接重建方法中的反投影时所需的运算大大降低,并将重建时间比同类方法缩短了几倍,而且随着重建图象的尺寸的增大,重建时间以2的指数次方倍相对缩短,并获得了较好质量的重建图象;另外,又根据平行束投影重建图象的思想,对扇形射束进行了重排,然后利用平行束重建图象的方法进行扇束的重建,并推导了&扇束重排重建图象&方法的约束条件。

In order to study the intake air flow characteristics in four-valve diesel engines, in this dissertation hot-wire anemometer and PIV twodimension instantaneous measuring technique are used. Extensive experimental study on two intake valve exit flow fields and longitudinal section flow field in cylinder are performed for different type of diesel engines. Great researching progress have been made on the interaction between two intake ports, and the formation process of in-cylinder swirl and flow field structure of cross and longitudinal section for four valve diesel engines. These results are presented in China for the first time and without such kind of research work reported abroad as detailed and deepgoing as this dissertation. The author designs and makes a set of hot wire measuring velocity device to measure the velocity distribution around the intake valve annulus and the cross section flow field in cylinder.
