Fig. 1 is the system structure sketch map of fusion positron emission computerized tomography image of the present utility model and magnetic resonance imaging image.
The specific embodiment
For technical problem, technical scheme and advantage that embodiment of the present utility model will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiment of the present utility model provides a kind of system that merges positron emission computerized tomography image and magnetic resonance imaging image, can realize that the same machine of positron emission computerized tomography image and magnetic resonance imaging image merges.
As described in Figure 1, this system comprises:
Be used to generate the MR scanner 1 of magnetic resonance imaging image;
Be used to generate the positron emission computerized tomography device 2 of positron emission computerized tomography image, wherein, patient's centerline hole of positron emission computerized tomography device 2 becomes the Φ angle with patient's centerline hole of MR scanner 1, and Φ is not more than 180 ° greater than 0 °;
