Description
Technical Field
The invention relates to the technical field of nuclear magnetic resonance imaging, in particular to a nuclear magnetic resonance positioning method, a nuclear magnetic resonance positioning device, nuclear magnetic resonance positioning equipment and a storage medium.
Background
Magnetic Resonance Imaging (MRI) is one of the Imaging devices commonly used in clinical practice, and generally, it is a long ring-shaped structure (hollow cylinder), and due to the principle limitation, when performing MRI scanning, an object to be scanned needs to be placed at the center of the ring (up and down, left and right, and both front and back). Scanning positioning (positioning) refers to a process of placing a part of a patient to be diagnosed in the center of a ring, and is always one of important links of clinical magnetic resonance examination, and the efficiency of diagnosing and examining a focus is directly influenced by the quality of positioning.
At present, the most main positioning mode in clinical magnetic resonance examination is positioning by utilizing laser and an electric moving bed, wherein the laser is generally fixed on the end surface of a patient end, and a laser beam is vertical to the sickbed; the electric bed can accurately lift and move back and forth but cannot move left and right. If the primary positioning is not accurate, the time consumption is too long when the secondary positioning is carried out. Although the time of the scout scan is relatively short (5-10 seconds), before each scout scan, the MRI system needs to perform a series of pre-scan processes such as automatic center frequency, automatic shimming, automatic rf transmit gain, automatic receive gain, etc., which takes about 40-60 seconds. In order to obtain higher quality images, the above four pre-scan procedures must be performed to adjust the system to the optimum state whenever the patient is moving. The more times the positioning is performed, the longer it takes in the process. And if one positioning is unsuccessful, a doctor needs to enter a scanning room to guide the patient to move to adjust, and the process is usually carried out for many times due to lack of definite measurement and is very time-consuming. And this kind of location method only supports the electric bed, if do not have the electric bed that moves, only the bed body structure of the mechanical hand moving bed needs to get back to the operation room after preliminary laser positioning and scans the location image, just can see the relative position of the scanned position after scanning, if the position is inaccurate, then need to get into again and scan the room and adjust, get back to the operation room after adjusting and scan the location image, so repetition, it is very time consuming and energy to be accurate to the position.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Due to the limitation of the mri principle, a series of pre-scanning operations are performed before the mri scan is performed to adjust the scan parameters of the mri correspondingly, with a time of about 40-60 seconds, so as to achieve the optimal use state of the system. The invention provides a scheme for replacing the pre-scanning operation by using a preset ultra-fast single-frame imaging technology, and the scheme can save the time for carrying out nuclear magnetic resonance positioning.
Referring to fig. 1, an embodiment of the present application discloses a nuclear magnetic resonance positioning method applied to scan control software, including:
step S11: and determining a scanning visual field range by using the read current state information and the part registration information of the preset scanning control assembly.
In the embodiment, the read current state information of the preset scanning control assembly is utilized firstly; the part registration information registered by the patient on the clinical software is read, and the scanning visual field range is confirmed and determined in turn. Wherein the preset scan control component is shown in fig. 2. And the preset scanning control component is provided with a mode switching key 1, a starting key 2, a scanning direction selection key 3 and a layer selection sliding block 4. The mode switching key 1 switches the setting mode of the current state information of the preset scanning control component; the setting mode includes an automatic mode and a manual mode. Only one of the two keys can be pressed at the same time. In the automatic mode, the scanning is performed using preset positioning sequence parameters. Default sagittal, 0 scale. The user can set according to the requirement of the user. And in the manual mode, the current key information of the scanning control assembly is read, and scanning is executed according to the currently set direction and layer. The start key 2 is responsible for starting scanning the image in the field of view. And when the preset scanning control component is in a manual mode, setting the current state information of the preset scanning control component by using the scanning azimuth selection key 3 and the layer selection sliding block 4. The scanning direction selection key 3 is only effective in a manual mode; is responsible for the selection of the scanning orientation. The corresponding direction is selected according to the scanned part, and only one of the three keys can be pressed simultaneously. The layer selection slider 4 is only effective in the manual mode; is responsible for the selection of the scanning layer. The scale range is-10-10, corresponding to 20 layers of each layer of the current position. The number of layers corresponds to the coronal position of the reference imaging interpretation principle from bottom to top; sagittal from left to right; transverse position from front to back. And the preset scanning control assembly adopts operation structures such as a button, a sliding block and the like in design, so that the electromagnetic compatibility and magnetic compatibility characteristics are good, and the operation is easier.
Step S12: and controlling a preset spectrometer to perform positioning scanning on the part placed in the scanning visual field range based on a preset ultra-fast single-frame imaging technology to obtain scanning data.
In this embodiment, after the scanning visual field range is determined, the preset spectrometer is controlled to perform positioning scanning on the part placed in the scanning visual field range to obtain scanning data. At the moment, the preset spectrometer adopts a preset ultra-fast single-frame imaging technology to scan the part. Wherein the pulse sequence and parameters of the ultrafast single imaging scan in the automatic mode of the preset scan control component are: FLASH sequence, matrix64 × 64, TR0.01 second, time 0.64 second, orientation vector, level 0 scale, field of view (FOV) reading registration site; the preset scanning control component is in a manual mode as follows: FLASH sequence, matrix64 × 64, TR0.01 second, time 0.64 second, orientation reading controller, slice selection reading controller scale, field of view (FOV) read registration site. It can be understood that all parameter information of the ultra-fast single imaging scan can be preset or changed according to actual conditions. Therefore, the positioning operation by using the preset ultra-fast single-frame imaging technology only needs about 0.6 second. Whereas the original positioning operation with pre-scanning requires about 60 seconds. In this way, the positioning operation with pre-scanning is replaced by the positioning operation using the preset ultrafast single-frame imaging technique. A large amount of positioning time can be saved. Before the final shooting position of the nuclear magnetic resonance is determined, if the positioning is carried out for n times, the scanning time of (n-1) multiplied by 60s can be saved. It should be noted that, the ultra-fast single-frame imaging scanning sequence in the ultra-fast single-frame imaging technology is preset, the scanning speed of the sequence is fast, and the sequence is insensitive to parameters such as center frequency, shimming, radio frequency pulse intensity and the like which need to be adjusted through pre-scanning, and can be directly operated without pre-scanning.
In this embodiment, before controlling a preset spectrometer to perform positioning scanning on a location within the scanning field of view based on a preset ultrafast single-frame imaging technique to obtain scanning data, the method further includes: and sending the scanning control signal generated by the preset scanning control component to an operation workstation in a preset control room through a preset signal transmission line so that the operation workstation forwards the scanning control signal to the preset spectrometer. The nuclear magnetic resonance apparatus used in the present invention is shown in fig. 3. In this way, the doctor can control the preset spectrometer to perform positioning scanning on the part placed in the scanning visual field range based on the preset scanning control component in the doctor examination room. The doctor does not need to go in and out of the scanning room, and the workload of the doctor is reduced.
Step S13: and performing image reconstruction based on the scanning data to generate a part scanning image and displaying the part scanning image on a preset display.
In this embodiment, the reconstructing an image based on the scan data to generate a part scan image and displaying the part scan image on a preset display includes: performing image reconstruction based on the scan data to generate an initial scan image; and adding a central scale mark to the initial scanning image based on the scanning visual field range to obtain a part scanning image and displaying the part scanning image on a preset display. The center scale line displayed on the preset display is shown in fig. 4, the displayed picture includes the center scale line, and the scale on the center scale line changes along with the scanning visual field range. Therefore, a user can check whether the part scanning image meets the preset nuclear magnetic resonance position standard or not according to the picture on the preset display.
In this embodiment, the displaying the part scanning image on a preset display includes: and transmitting the part scanning image in the operation workstation of the preset control room to a preset display in a preset examination room through a preset video transmission line. The nuclear magnetic resonance apparatus used in the present invention is shown in fig. 3. The preset display is arranged in the examination room. Therefore, a doctor can clearly see whether the part scanning image meets the preset nuclear magnetic resonance position standard in the examination room, and does not need to go in and out of a scanning room, so that the workload of the doctor is reduced. In addition, because the doctor does not need to go into and out of the scanning room frequently, when carrying out complicated location operation, can know at any time that patient carries out corresponding autonomous movement, because this kind of mode of adjusting the location does not need to remove the beddo, consequently can save the operation process of laser location in original nuclear magnetic resonance location, further improved work efficiency.
Taking the knee joint as an example, the invention is compared with the prior nuclear magnetic positioning technology based on actual operation. In the prior art, firstly, a scanned part is moved to the center of a magnet by using the self-carried laser positioning of a magnetic resonance imaging system; the physician then leaves the scan room and enters the suite. A doctor adjusts positioning parameters through scanning software, starts positioning scanning for about 60s; from the positioning image, there are two cases: a. adjusting the electric moving bed to enable the scanning part to be positioned at the center; b. if the patient can not be moved by the electric moving bed (for example, the L-R direction is not at the center), the patient needs to enter the scanning room to move the body to reach the center; adjusting the parameters again to scan the positioning image, and completing the positioning for about 60s; and adjusting the parameter again to scan the scout image, observing whether the scout image is in the center, and if the scout image is not in the center, repeatedly moving the body of the patient to reach the center and adjusting the parameter again to scan the scout image. The technology of the invention is to displace (electrically or manually) the scanned part to the center of the magnet; performing ultra-fast positioning scanning by using a scanning control assembly for 1s, wherein the image is displayed on an image display at the moment; taking the central scale mark as a reference, moving the sickbed or guiding the patient to move autonomously to perform corresponding adjustment according to the image on the image display; the start button is clicked again and the new image is observed. Then repeating the operation of using the scanning control assembly to perform ultra-fast positioning scanning until the position is accurate; the doctor returns to the operating room and performs a scout scan in about 60s. Therefore, the method of the invention can greatly reduce the operation difficulty of the doctor and save the time for the doctor to perform positioning operation.
As can be seen, in this embodiment, first, the current state information and the part registration information of the preset scanning control component are read to determine the scanning view range; controlling a preset spectrometer to perform positioning scanning on a part placed in the scanning visual field range based on a preset ultra-fast single-frame imaging technology to obtain scanning data; and performing image reconstruction based on the scanning data to generate a part scanning image and displaying the part scanning image on a preset display. Therefore, in the invention, the preset ultra-fast single-frame imaging technology is adopted to replace the traditional imaging method with the pre-scanning to obtain the part scanning data in the visual field range, and the scanning data is converted into the part scanning image to be displayed on the preset display, so that a user can determine whether the nuclear magnetic resonance positioning is successful or not through the part scanning image displayed on the preset display. Therefore, the nuclear magnetic resonance positioning image before formal examination can be quickly acquired, and because a doctor does not need to frequently go in and out of a scanning room, the patient can be guided to correspondingly move autonomously at any time when complex positioning operation is carried out, and because the positioning adjustment mode does not need to move the electric bed, the operation process of laser positioning in the original nuclear magnetic resonance positioning can be omitted, and the examination efficiency is greatly improved.
