Embodiment 1
[0070] The embodiment of the present invention provides a data processing method, such as figure 1 Shown, can be applied in PET-MR equipment, this method comprises the following steps:
[0071] 101. Acquire positioning image data of the designated target.
[0072] In a specific implementation, one of the following two methods can be used to obtain the positioning image data of the specified target:
[0073] Method 1: Perform magnetic resonance MR positioning scan on the specified target, and obtain positioning image data of the specified target.
[0074] Method 2: Perform positron emission tomography PET positioning scan on the specified target, and obtain a positioning image of the specified target.
[0075] Specifically, when performing a positioning scan on a specified target, an MR positioning scanning device can be used to perform an MR positioning scan on the specified target, or a PET positioning scanning device can also be used to perform a PET positioning scan on th...
Embodiment 2
[0110] In order to further illustrate the technical idea of the present application, the technical solution of the present application is described in combination with specific application scenarios. Such as Figure 7 As shown, when the patient undergoes PET-MR imaging, he needs to lie on the detection bed of the PET-MR equipment, and is divided into four beds for scanning and imaging. When PET-MR imaging is performed each time, one bed is scanned each time, corresponding to the positioning image As part of , the method may include the steps of:
[0111] 1. Perform a PET positioning scan on the patient to obtain the positioning image data of the patient.
[0112] Specifically, the part corresponding to the positioning image data has the same position and size as the four parts of the bed.
[0113] 2. Take the PET-MR imaging of the first part as an example, and acquire the positioning image data corresponding to the first part.
[0114] Specifically, such as Figure 7 As ...
Embodiment 3
[0127] The embodiment of the present invention proposes a data processing device, such as Figure 8 As shown, the device may include:
[0128] A first acquiring unit 81, configured to acquire positioning image data of a designated target;
[0129] The second acquiring unit 82 is configured to acquire, according to the positioning image data, coordinate data corresponding to the contour area of the designated target in the positioning image data;
[0130] The determining unit 83 is configured to determine the field of view FOV of the MR image according to the coordinate data corresponding to the outline area of the designated target.
[0131] In a specific embodiment, when the first acquiring unit 81 is used to acquire the positioning image data of the designated target, it is specifically configured to: perform a magnetic resonance MR positioning scan on the designated target, and acquire the positioning image of the designated target data; or, performing a positron emis...
