| titleOfInvention | A system and method for reconstructing an image of a scanning device |
| abstract | The present invention provides a system and method for reconstructing an image of a scanning device, comprising: placing a phantom in a preset area of a scanning field of view, and obtaining the relative positional relationship between the phantom and the center of the scanning field of view; defining a response line, And calculate the intersection length of the response line and the phantom; collect coincident events, and count the number of coincident events included in the response line to calculate the average value of the flight time difference of the response line; the average value of the flight time difference Correction is performed to obtain a mean correction value of time-of-flight difference; a calculation model is established; the calculation model is used to obtain the temporal resolution of each detector; and the temporal resolution of each detector is used to reconstruct the image. The present invention provides a system and method for reconstructing an image of a scanning device, which can improve the quality of the reconstructed image. |
