| 摘要 |
A method and a system are disclosed for calibrating an emission tomography subsystem in a combined MR (magnetic resonance) and emission tomography imaging system. In at least one embodiment, the method includes providing a phantom that is configured such that the phantom is visible on a MR image, providing an attenuation map of the phantom, wherein the attenuation map includes an attenuation of the phantom, obtaining the MR image of the phantom, obtaining a position of the phantom from the MR image, mapping the attenuation map with the position of the phantom, and calibrating the emission tomography subsystem using the attenuation map mapped with the position of the phantom.
