An embodiment of the present invention provides a protocol parameter configuration method, which is applicable to a medical device, and please refer to fig. 1, which is a flowchart illustrating a method provided in an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
101. and acquiring an MR attenuation correction protocol list set by a user, wherein the MR attenuation correction protocol list comprises a plurality of MR attenuation correction protocol parameters.
The MR attenuation correction protocol parameter list is stored in a designated storage structure, the MR attenuation correction protocol list comprises a plurality of MR attenuation correction protocols, each MR attenuation correction protocol is an MR attenuation correction protocol parameter set, and parameters in the protocol parameter set are used for carrying out attenuation correction on different data acquired by the PET.
The storage structure is open to the user, i.e. the user can view the MR attenuation correction protocol list in the storage structure, and can also edit the MR attenuation correction protocol parameters in the MR attenuation correction protocol list. In order to facilitate user operation, the execution terminal provides an editable interface for a user, when the user clicks the specified position of the display screen of the terminal through a mouse or other equipment, the terminal is triggered to display the editable interface, and the user realizes editing of the storage structure by executing the specified operation on the editable interface, so that the MR attenuation correction protocol list is set.
Specifically, for example, there are some operation controls in the editable interface, each operation control may implement a corresponding editing function, and a user may add an MR attenuation correction protocol to the MR attenuation correction protocol list by clicking the operation controls; or deleting the specified MR attenuation correction protocol in the MR attenuation correction protocol list; or, modifying the MR attenuation correction protocol parameters in the MR attenuation correction protocol list, and the like.
102. And positioning the PET bed to be corrected.
When scanning and detecting a scanning object, generally, each detection part of the scanning object has a corresponding relation with a bed of a scanning device, and the execution main body positions a PET bed to be corrected by judging the detection part of the scanning object.
103. And determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected.
It should be noted that, because different human tissues have different influences on photons, different MR attenuation correction protocol parameters need to be used for different detection portions of the scanned object to remove the influences of the different detection portions on the photons in order to ensure high image quality of the finally obtained PET image. Therefore, the bed to be corrected is positioned by utilizing the corresponding relation between each detection part of the scanning object and the bed of the scanning device, and the corresponding MR attenuation correction protocol parameters are selected for the positioned bed to be corrected, so that the influence of different detection parts on photons collected by PET is corrected to different degrees, and the accuracy of the PET data obtained through processing is ensured.
According to the technical scheme provided by the embodiment of the invention, the PET bed to be corrected is positioned by acquiring the MR attenuation correction protocol list set by the user, and then the corresponding MR attenuation correction protocol parameters are configured for the PET bed to be corrected from the MR attenuation correction protocol list set by the user. Compared with the prior art that fixed MR attenuation correction protocol parameters are set, and the data acquired by the bed to be corrected of the PET are corrected by using one fixed MR attenuation correction protocol parameter, the method and the device implement the MR attenuation correction protocols corresponding to different correction bed configurations, thereby ensuring accurate correction of the data acquired by the bed to be corrected of the PET and improving the quality of the PET image.
Further, when the terminal detects a scanned object, each scanned bed of the terminal is an appointed detection part, based on which, the embodiment of the present invention provides an implementation method for implementing positioning of a PET bed to be corrected in step 102, as shown in fig. 2, step 102 specifically includes:
1021. and determining the part to be detected of the scanning object.
The terminal carries out pre-scanning on the scanning object, matches the result obtained by the pre-scanning with the structure diagram of the scanning object stored by the execution terminal, and determines the part to be detected of the scanning object.
1022. And determining the PET bed to be corrected according to the part to be detected.
The part to be detected of the scanning object has a corresponding relation with the bed of the scanning device, and the executive main body determines the PET bed to be corrected by utilizing the obtained part to be detected through the corresponding relation.
Further, for the implementation of determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected in step 103, the embodiment of the present invention provides the following two implementation methods,
in the first implementation method, the execution body stores the corresponding relation of the MR attenuation correction protocol parameters which are allocated to each PET bed by the user.
It should be noted that, in order to enable the user to assign the MR attenuation correction protocol to each PET bed, the executing subject needs to display the MR attenuation correction protocol list to the user, so that the user can acquire the MR attenuation correction protocol that the user wants to assign to each PET bed, and thus the executing subject can acquire the corresponding MR attenuation correction protocol parameter that the user assigns to each PET bed according to the MR attenuation correction protocol list. When the MR attenuation correction protocol is allocated to each PET bed, the executive body can also display the PET bed needing to be configured with MR attenuation correction protocol parameters to a user or can input the corresponding PET bed by the user, so that the user allocates MR attenuation correction protocol parameters to the PET bed, and the corresponding relation between each PET bed and the MR attenuation correction protocol is established.
As shown in fig. 3, the implementation of the step 103 of determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected specifically includes:
1031a, allocating corresponding MR attenuation correction protocol parameters to each PET bed according to the PET bed to be corrected and the user, and determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected.
And matching the PET bed to be corrected with the PET bed set by the user, thereby determining that the MR attenuation correction protocol of the PET bed to be corrected is the MR attenuation correction protocol parameter corresponding to the matched PET bed set by the user.
In a second implementation manner, the MR attenuation correction protocol list acquired by the execution subject is configured with the specified correspondence relationship between the MR attenuation correction protocol parameters and the detection parts of the scanning object.
As shown in fig. 4, the implementation of the step 103 of determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected specifically includes:
1031b, matching the part to be detected with each detection part in the protocol list to determine the MR attenuation correction protocol parameters corresponding to the part to be detected.
1032b, determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected according to the MR attenuation correction protocol parameters corresponding to the part to be detected.
Each detection part of the scanning object has a corresponding relation with the MR attenuation correction protocol parameters, and each detection part of the scanning object also has a corresponding relation with the PET bed, so that the execution body can select the specified MR attenuation correction protocol for the PET bed to be corrected through the two corresponding relations.
Further, in order to ensure that the MR attenuation correction protocol parameters used by the bed to be corrected can be accurately corrected by the data acquired by the PET, as shown in fig. 5, after determining the MR attenuation correction protocol parameters corresponding to the PET bed to be corrected, the method further includes:
104. and acquiring the MR attenuation correction protocol parameters after the MR attenuation correction protocol parameters corresponding to the specified PET bed are adjusted by the user.
105. Acquiring PET data based on the adjusted MR attenuation correction protocol parameters.
It should be noted that the protocol parameter after the adjustment of the MR attenuation correction protocol parameter corresponding to the PET bed to be corrected by the user is a temporary parameter, and is only used for correcting the PET bed to be corrected this time. If the temporary parameter is used a relatively large number of times, the user also adds the temporary parameter to the MR fall-off correction protocol list in the manner set forth in step 101 to set the MR fall-off correction protocol list.
It should be added that the embodiment of the present invention further provides an examination function of MR attenuation correction protocol parameters, and in a manner, before a user adjusts MR attenuation correction protocol parameters, the execution main body displays an adjustable range of the MR attenuation correction protocol parameters to the user for reference, so as to reduce a condition that an image scanned by a system cannot reach PET attenuation correction due to the fact that MR attenuation correction protocol parameters modified by the user exceed the range. The other mode is that after a user sets modified protocol parameters, the executive main body acquires MR attenuation correction protocol parameters set by the user, judges whether the MR attenuation correction protocol parameters meet the requirements of the MR attenuation correction protocol parameters or not, displays the judgment result to the user, and acquires PET data based on the first adjustment protocol parameters if the first adjustment protocol parameters meet the requirements of the MR attenuation correction protocol parameters; if the first adjustment protocol parameter is judged not to meet the MR attenuation correction protocol parameter requirement, the user continues to adjust the first adjustment protocol parameter to obtain a second adjustment protocol parameter, the second adjustment protocol parameter adjusted by the user on the first adjustment protocol parameter is obtained, and the second adjustment protocol parameter is judged until the protocol parameter meeting the MR attenuation correction protocol parameter requirement is obtained. The accuracy of PET attenuation correction can be improved to a certain extent by checking whether the MR attenuation correction protocol parameters meet the requirements.
The MR attenuation correction protocol parameter requirements comprise whether the scanning range of the MR image contains the coverage range of the PET under the bed, whether the resolution size of the MR image meets the minimum requirement, whether the information contained in the MR image meets the requirement of a PET correction algorithm, whether the MR image can be completely matched with the PET image on a control, and the like.
