Abstract
A method and apparatus of image position compensation are provided. The method may include: measuring an actual height at Z position and a corresponding drop offset of a scanning table; adjusting, according to the drop offset of the scanning table, a vertical coordinate of an image center in the process of post-reconstruction, so as to obtain an adjusted image; and performing an interpolation process on coordinate information and pixel values of a row in the adjusted image, to obtain pixel values of a row in a target image. The target image is an image which has been processed by position compensation. According to the present disclosure, an image generated by a CT apparatus can be compensated to obtain a correct tomographic image and provide accurate image information for medical diagnosis.
