| titleOfInvention | The geometric correction method of the optical projection computed tomography (SPECT) system based on imitative body |
| abstract | The geometric correction method of the optical projection computed tomography (SPECT) system based on imitative body that the present invention is provided, including：Two-dimensional projection data is obtained data acquisition is carried out to imitative body, and the two-dimensional projection data is carried out into three-dimensional reconstruction to obtain three-dimensional reconstruction data, the three-dimensional reconstruction data include sample rotation axis horizontal offset information and rotation information；According to sample rotation axis horizontal skew and the rotation information acquisition sample rotation axis horizontal offset information and the corresponding rotation axis horizontal side-play amount of rotation information and the anglec of rotation；The rotation axis horizontal side-play amount and the corresponding horizontal-shift of the anglec of rotation and rotation offset are carried out by geometric correction by the rotation axis horizontal side-play amount and the anglec of rotation respectively.The present invention can improve the spatial resolution of optical projection computed tomography (SPECT) system, reduce the artifact of image. |
