Description of drawings
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, patient's centerline hole of positron emission computerized tomography device 2 is parallel with patient's centerline hole of MR scanner 1 and on same vertical plane;
Place between positron emission computerized tomography device 2 and the MR scanner 1, but rectilinear translation is patient bed 3, and patient bed 3 centrage is parallel with patient's centerline hole of MR scanner 1 and on same vertical plane;
Be used to control positron emission computerized tomography device 2 and MR scanner 1 imaging, store, show and utilize the position relation between the tomograph to merge magnetic resonance imaging image and positron emission computerized tomography image, and the operating equipment of controlling patient bed 3 rectilinear translations, be connected respectively with patient bed 3 with positron emission computerized tomography device 2, MR scanner 1.
Wherein, patient bed 3 comprise:
But the patient bed bed body of rectilinear translation and be support with patient bed bed body, but on patient bed bed body the bed board of rectilinear translation.But patient bed bed body and bed board be height up and down all; Patient bed 3 also comprise the adjusting device of the height that is used to regulate patient bed bed body and bed board.
As shown in Figure 1, patient's PET centerline hole is parallel with patient's MRI centerline hole and at same vertical plane, and patient bed 3 can be between two equipment, and parallel patient's centerline hole moves.
The magnetic field of MRI becomes the ellipse trapezoidal profile, outside from the MRI magnet center, magnetic field more and more a little less than, in order to reduce interacting between MRI equipment and the PET equipment, PET equipment can be placed on beyond 1 gaussian line of MRI equipment, particularly, the distance between MRI equipment and the PET equipment can be 3-7 rice.But because the equal rectilinear translation of patient bed bed body and bed board, so can satisfy distance between MRI equipment and PET equipment when enough far away, the patient on patient bed also can move to the inspection area of another one equipment from the inspection area of an equipment.
