Visualization of internal structure of fuel spray using laser computed tomography technique(1)——A study of image reconstruction algorithms for fuel spray

According to the characteristics of fuel spray,CBP(Convolution back projection),ART (Algebraic reconstruction technique) and SIRT (Simultaneous iterative reconstruction technique) were studied on the image reconstruction of fuel spray.The reconstruction results of the phantom using P540 digital image processing system showed that when there is noise in the projection data,the best image was reconstructed by SIRT whose calculation time was longest,the worst image was reconstructed by CBP whose calculation time was shortest,and ART is between them.
