Description

Technical Field

[0001] The present application relates to the field of magnetic resonance technology, and in particular to magnetic resonance equipment, a method for determining a magnetic resonance scanning protocol, a device and a storage medium. Background Art

[0002] At present, magnetic resonance imaging has become an important means of clinical diagnosis. However, for parts with respiratory movement such as the chest, heart, abdomen, etc., after scanning with conventional scanning technology, image motion artifacts are very serious due to breathing, which seriously affects the image effect. Conventional abdominal scanning uses breath holding to ensure that the liver is fixed, and the scanning time can be faster than free breathing. At this time, the patient needs to cooperate with breath holding. However, different patients have different breath holding abilities and different degrees of cooperation. Currently, hospitals usually conduct breath holding training for patients before scanning, and most of them are verbal communication to improve patient cooperation. For patients who cannot hold their breath well, a free breathing scanning scheme is adopted. At this time, the patient also needs to be guided to breathe. Regular breathing helps to select the appropriate acquisition time and improve acquisition efficiency. In the existing scheme, the operator of the magnetic resonance equipment determines the magnetic resonance scanning protocol based on experience, and does not conduct breathing training on the patient. The scanning protocol of the magnetic resonance is determined based on the actual breathing data after breathing training, which results in the determined magnetic resonance scanning protocol being inappropriate, resulting in low quality of magnetic resonance images.

In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0047] In the present application, a magnetic resonance device is provided. Figure 2 is a structural block diagram of a magnetic resonance device according to an embodiment of the present application, such as Figure 2 As shown, the device includes: a control module 210, an audio and video playback module 220 and a sensor module 230, and the audio and video playback module 220 and the sensor module 230 are respectively connected to the control module 210.

[0048] Specifically, the audio and video playback module 220 is used to receive the breathing training program sent by the control module 210, and play the breathing training program to guide the user to perform breathing training according to the breathing training program. The sensor module 230 is used to collect the breathing data generated when the user performs breathing training according to the breathing training program, and send the breathing data to the control module 210. The control module 210 is used to generate a breathing training program, send the breathing training program to the audio and video playback module 220, and determine the target scanning protocol according to the received breathing data.

[0049] More specifically, the control module 210 generates a corresponding breathing training program according to the setting of the magnetic resonance device operator, and the control module 210 sends the generated breathing training program to the audio and video playback module 220. After receiving the breathing training program, the audio and video playback module 220 plays the breathing training program, and the playback here includes audio playback and video playback. The user performs breathing training synchronously according to the breathing training program played by the audio and video playback module 220, and the sensor module 230 collects the breathing data generated by the user when performing breathing training according to the breathing training program in real time, and the sensor sends the real-time collected breathing data to the control module 210. The control module 210 generates breath holding quality data and free breathing quality data according to the received breathing data, and determines the target scanning protocol according to the breath holding quality data and the free breathing quality data. The scanning protocol generated by the control module 210 here includes a breath holding scanning protocol and a triggered scanning protocol. When the breath-hold quality data reaches a first preset condition, the target scanning protocol is determined according to the breath-hold quality data; the first preset condition is determined according to the parameters of the breath-hold scanning protocol; when the breath-hold quality data does not reach the first preset condition and the free breathing quality data reaches a second preset condition, the target scanning protocol is determined according to the free breathing quality data; the second preset condition is determined according to the parameters of the trigger scanning protocol. The free breathing quality data here is the quality data generated according to the real-time data generated by the user when breathing freely, and the breath-hold quality data here is the quality data generated according to the real-time data generated by the user when holding his breath.

[0050] Exemplarily, the breathing training scheme here includes a breathing training scheme related to the breath-hold scanning protocol and a breathing training scheme related to the trigger scanning protocol. When the operator of the magnetic resonance device selects the breathing training scheme related to the breath-hold scanning protocol, the audio and video playback module 220 includes audio and video guidance information for guiding the user to perform free breathing training and guiding the user to perform breath-hold training. The audio and video guidance information at least includes audio or video signals for guiding the user to perform free breathing, guiding the user to start holding the breath, and guiding the user to end holding the breath. The audio and video playback module 220 here can be set on the inner wall of the aperture of the magnetic resonance device to facilitate the user to perform breathing training. For example, the audio and video playback module 220 can be displayed on the inner wall of the aperture in a projection manner above the user's line of sight after entering the aperture; the sensor module 230 here is used to sense the amplitude of abdominal movement. The sensor module 230 here can be an abdominal strap or a millimeter wave radar; the user here can be a patient who needs to undergo magnetic resonance scanning.

[0051] In this embodiment, the control module sets a breathing training program and sends it to the audio and video playback module. The audio and video playback module plays the breathing training program to guide the user to perform breathing training synchronously according to the breathing training program played by the audio and video playback module. The sensor module collects the breathing data generated by the user when performing breathing training according to the breathing training program in real time, generates breath holding quality data and free breathing quality data according to the received breathing data, and determines the target scanning protocol according to the breath holding quality data and the free breathing quality data. The scanning protocol generated by the control module is not set based on experience, but is generated based on the breathing data generated by the user after breathing training. This solves the problem in the prior art that the magnetic resonance scanning protocol determined by the magnetic resonance equipment operator based on experience is inappropriate, resulting in low quality of the magnetic resonance image.

[0052] The present application provides a method for determining a magnetic resonance scanning protocol. Figure 3 is a flow chart of a method for determining a magnetic resonance scanning protocol according to an embodiment of the present application. Figure 3 As shown, the process includes the following steps:

[0053] Step S310, generating a breathing training program, and sending the breathing training program to the audio and video playback module.

[0054] Specifically, the control module generates a corresponding breathing training program according to the setting of the magnetic resonance device operator, and the control module sends the generated breathing training program to the audio and video playback module.

[0055] Step S320, receiving the breathing data sent by the sensor module; the breathing data is the breathing data generated by the sensor module when the user performs breathing training according to the breathing training program. The scanning protocol generated by the control module here includes a breath-hold scanning protocol and a trigger scanning protocol.

[0056] Specifically, after receiving the breathing training program, the audio and video playback module plays the breathing training program. The user performs breathing training synchronously according to the breathing training program played by the audio and video playback module, the sensor module collects breathing data generated by the user when performing breathing training according to the breathing training program in real time, the sensor sends the real-time collected breathing data to the control module, and the control module receives the breathing data sent by the sensor module.

[0057] Step S330: determining a target scanning protocol according to the breathing data.

[0058] Specifically, the control module generates breath-holding quality data and free breathing quality data according to the received breathing data, and determines the target scanning protocol according to the breath-holding quality data and the free breathing quality data. The target scanning protocol here can be understood as the scanning protocol adopted by the magnetic resonance device when performing a formal magnetic resonance scanning on the user.

[0059] In this embodiment, the control module sets a breathing training program and sends it to the audio and video playback module. The audio and video playback module plays the breathing training program to guide the user to perform breathing training synchronously according to the breathing training program played by the audio and video playback module. The sensor module collects the breathing data generated by the user when performing breathing training according to the breathing training program in real time, generates breath holding quality data and free breathing quality data according to the received breathing data, and determines the target scanning protocol according to the breath holding quality data and the free breathing quality data. The scanning protocol generated by the control module is not set based on experience, but is generated based on the breathing data generated by the user after breathing training. This solves the problem in the prior art that the magnetic resonance scanning protocol determined by the magnetic resonance equipment operator based on experience is inappropriate, resulting in low quality of the magnetic resonance image.

[0060] In some of the embodiments, determining a target scanning protocol based on breathing data includes: generating breath-hold quality data and free breathing quality data based on the breathing data, and when the breath-hold quality data reaches a first preset condition, determining the target scanning protocol based on the breath-hold quality data; the first preset condition is determined based on parameters of the breath-hold scanning protocol; when the breath-hold quality data does not reach the first preset condition and the free breathing quality data reaches a second preset condition, determining the target scanning protocol based on the free breathing quality data; the second preset condition is determined based on parameters of the trigger scanning protocol.

[0061] Specifically, when the breath-holding quality data reaches the first preset condition, the control module determines the target scanning protocol according to the breath-holding quality data. For example, the first preset condition here may be that the breath-holding time in the breath-holding quality data can reach the breath-holding time requirement of the breath-holding scanning protocol, and the abdominal wall movement amplitude in the breath-holding quality data can meet the abdominal wall movement amplitude requirement of the breath-holding scanning protocol. When the breath-holding time in the breath-holding quality data can reach the breath-holding time requirement of the breath-holding scanning protocol, and the abdominal wall movement amplitude in the breath-holding quality data can meet the abdominal wall movement amplitude requirement of the breath-holding scanning protocol, the target scanning protocol is determined to be the breath-holding scanning protocol, that is, after the user undergoes breathing training, the user's breath-holding quality data can meet the requirements of the breath-holding scanning protocol, and the breath-holding scanning protocol can be used to realize the acquisition of the user's magnetic resonance image. More specifically, different breath-hold scanning protocols can be selected according to the maximum value of the breath-hold time in the user's breath-hold quality data. For example, due to different acceleration technologies in magnetic resonance scanning, the duration of a single magnetic resonance breath-hold protocol varies, so the single breath-hold duration generally needs to be 12s, 15s, 18s, and 20s, etc. The control module determines the breath-hold scanning protocols with different breath-hold durations according to the user's breath-hold duration. Determining the target scanning protocol according to the breath-hold quality data herein can be generating a corresponding breath-hold scanning protocol as the target scanning protocol according to the breath-hold quality data, or can be selecting a breath-hold scanning protocol that matches the breath-hold quality data from an existing breath-hold scanning protocol set as the target scanning protocol according to the breath-hold quality data.

[0062] In addition, specifically, when the breath-holding quality data does not reach the first preset condition and the free breathing quality data reaches the second preset condition, that is, the breath-holding quality data of the user cannot meet the requirements of the breath-holding scanning protocol, but the free breathing quality data of the user can meet the requirements of the trigger scanning protocol. For example, the second preset condition here can be that the breathing stability in the free breathing quality data can meet the requirements of the trigger scanning protocol for breathing stability. When the breathing stability in the free breathing quality data can meet the requirements of the trigger scanning protocol for breathing stability, the target scanning protocol is determined to be the trigger scanning protocol, that is, after the user undergoes breathing training, the collected breath-holding quality data cannot meet the requirements of the breath-holding scanning protocol, but the free breathing quality data of the user can meet the requirements of the trigger scanning protocol. At this time, the breath-holding scanning protocol can be used to realize the acquisition of the user's magnetic resonance image. The breathing stability here is used to evaluate the quality of free breathing, which can be characterized by the frequency of exhalation and inhalation during the user's breathing process and the amplitude of movement of the abdominal wall during the breathing process.

[0063] In some embodiments, the breath-holding quality data includes the longest breath-holding time and the range of motion of the abdominal wall generated according to the respiratory data; and the free breathing quality data includes the duration of the respiratory interval plateau and the respiratory stability data generated according to the respiratory data.

[0064] In some of the embodiments, when the breath-hold quality data does not meet the first preset condition and the free breathing quality data meets the second preset condition, a target scanning protocol is determined based on the free breathing quality data, including: calculating the signal acquisition period, triggering moment and overall scanning time of the triggered scanning protocol based on the duration of the respiratory interval plateau and the respiratory stability data; generating a target triggered scanning protocol based on the signal acquisition period, triggering moment and overall scanning time of the triggered scanning; and determining the generated target triggered scanning protocol as the target scanning protocol.

[0065] Specifically, when the breath-hold quality data does not meet the first preset condition and the free breathing quality data meets the second preset condition, the control module calculates the signal acquisition period, trigger moment and overall scanning time of the triggered scanning inspection of the triggered scanning protocol according to the duration of the respiratory interval plateau and the respiratory stability data. The control module generates a target triggered scanning protocol according to the signal acquisition period, trigger moment and overall scanning time of the triggered scanning inspection, and determines the generated target triggered scanning protocol as the target scanning protocol.

[0066] In some embodiments, the breathing training program includes a first breathing training program and a second breathing training program, and generating the breathing training program includes: generating the first breathing training program according to a triggered scanning protocol, and generating the second breathing training program according to a breath-hold scanning protocol.

[0067] Specifically, the control module generates a first breathing training program according to the triggered scanning protocol, and generates a second breathing training program according to the breath-hold scanning protocol. The control module can select a target triggered scanning protocol from a preset triggered scanning protocol set, and generate the first breathing training program according to the target triggered scanning protocol; the control module can also select a target breath-hold scanning protocol from a preset breath-hold scanning protocol set, and generate the second breathing training program according to the target breath-hold scanning protocol.

[0068] In some of the embodiments, sending a breathing training plan to an audio and video playback module includes: sending a first breathing training plan to the audio and video playback module in response to a user position signal sent by a sensor module; sending a second breathing training plan to the audio and video playback module after a preset time; or, sending a second breathing training plan to the audio and video playback module in response to a second breathing training plan request signal from the audio and video playback module.

[0069] Specifically, the control module sends the first breathing training program to the audio and video playback module in response to the user position signal sent by the sensor module. When the user is at the target position of the bed board of the magnetic resonance device and the bed board of the magnetic resonance device moves to the designated position, the user arrives at the designated position and breathing training can be performed on the user. When the user is at the designated position, the sensor module sends a user position signal to the control module, and the control module sends the first breathing training program to the audio and video playback module in response to the user position signal. The audio and video playback module plays the first breathing training program to perform free breathing training on the user. Exemplarily, the sensor module includes a pressure sensor and an image sensor, the pressure sensor includes an abdominal strap, and the image sensor includes a camera, a millimeter wave radar, etc., and the pressure sensor or the image sensor is used to determine whether the user has arrived at the designated position.

[0070] In addition, specifically, after the first breathing training program is sent to the audio and video playback module, after the preset time, the control module sends the second breathing training program to the audio and video playback module, and the audio and video playback module plays the second breathing training program to perform breath holding training on the user. Optionally, after the first breathing training program of the audio and video playback module is played, the audio and video playback module sends the second breathing training program request signal to the control module, and the control module responds to the second breathing training program request signal, sends the second breathing training program to the audio and video playback module, and the audio and video playback module plays the second breathing training program to perform breath holding training on the user. Preferably, the control module controls the audio and video playback module to play the second breathing training program for N cycles, wherein N is a positive integer greater than or equal to 3, and in the process of playing the second breathing training program, the sensor module collects the N cycle breathing data generated when the user performs breathing training according to the second breathing training program in real time, and the N cycle breathing data are weighted averaged to generate breath holding quality data, and the weighting coefficient here can be determined according to the stationarity of the breathing data of each cycle.

[0071] In this embodiment, when the user reaches the designated position, the breathing training of the first breathing training program is performed first. After the first breathing training program is completed, the breathing training of the second breathing training program is performed. At this time, collecting the patient's breathing state can avoid the patient's breathing state being unstable when collecting the breathing interval after the patient holds his breath, and the breathing state changes during training, which makes the collected free breathing data inaccurate.

[0072] In some of the embodiments, after determining the target scanning protocol according to the breath-holding quality data and the free breathing quality data, the method further includes: generating a breathing guidance instruction according to the target scanning protocol, and sending the breathing guidance instruction to the audio and video playback module.

[0073] Specifically, after determining the target scanning protocol according to the breath-holding quality data and the free breathing quality data, the control module generates a breathing guidance instruction according to the target scanning protocol, and sends the breathing guidance instruction to the audio and video playback module. The audio and video playback module plays the breathing guidance instruction to guide the user to breathe freely or hold his breath during the formal scanning process.

[0074] In some of the embodiments, when the breath-hold quality data does not meet a first preset condition and the free breathing quality data does not meet a second preset condition, a prompt message is generated.

[0075] Specifically, when the breath-hold quality data does not meet the first preset condition and the free breathing quality data does not meet the second preset condition, that is, the user's breath-hold quality data cannot meet the requirements of the breath-hold scanning protocol, and the user's free breathing quality data cannot meet the requirements of the trigger scanning protocol, then it is impossible to determine a suitable target scanning protocol to perform a magnetic resonance scan on the user. At this time, the control module generates a prompt message to prompt the magnetic resonance equipment operator that the current user cannot match a suitable target scanning protocol or to prompt the magnetic resonance equipment operator that the current user is at risk of scanning failure, etc. The risk of scanning failure here may be the presence of breathing artifacts in the magnetic resonance image.

[0076] Another method for determining a magnetic resonance scanning protocol is provided in the present application. Figure 4 is a flow chart of another method for determining a magnetic resonance scanning protocol according to an embodiment of the present application. Figure 4 As shown, the process includes the following steps:

[0077] Step S410, the control module outputs the automated voice and video guidance content and synchronizes it to the audio and video playback module.

[0078] Specifically, when the patient enters the aperture and stabilizes, the control module outputs automated voice and video guidance content, and synchronizes it to the audio and video playback module in the aperture of the magnetic resonance device.

[0079] Step S420: the sensor module collects free breathing data.

[0080] Specifically, the audio and video playback module first plays the voice and the text projection in the aperture to remind the patient not to be nervous, keep relaxed and breathe freely. The sensor module senses the patient's breathing and breath holding in real time (sensing the amplitude of abdominal movement through the abdominal strap or millimeter wave radar). At this time, the patient's breathing quality and the duration of the respiratory interval plateau during steady breathing (i.e. free breathing) can be collected within 30 seconds, and the data is returned to the control module for subsequent evaluation. Collecting the patient's breathing state at this time can avoid the patient's breathing state being unstable when collecting the breathing interval after holding the patient's breath, and changes in breathing state during scanning, resulting in inaccurate triggering and affecting image quality.

[0081] Step S430: The control module calculates parameters for triggering a scanning protocol according to the free breathing data.

[0082] Specifically, the control module calculates the signal acquisition period, trigger time and overall scanning time of the triggered scan using the triggered protocol (the patient does not need to hold his breath, but can breathe freely) based on the collected stable breathing quality of free breathing (whether there is fast and slow breathing) and the duration of the plateau period between breathing, and determines the scanning success rate of the triggered scan protocol in the patient's normal breathing state based on the free breathing data.

[0083] Step S440: After a preset time, the audio and video playback module plays the breath-holding audio and video file.

[0084] Specifically, after a preset time, the audio and video playback module projects the breath-holding training audio and video file to guide the patient to follow the projected audio and video for breath-holding training. The preset time here must ensure that the free breathing data collection is completed, which can be greater than 30 seconds. The audio and video are recorded in advance in the entire process of the breath-holding method that the hospital is accustomed to using (including inspiratory breath-holding and expiratory breath-holding). The breath-holding time in the audio and video is longer than the general MRI single-line breath-holding protocol time, such as 20 to 25 seconds.

[0085] Step S450: the sensor module collects breath-holding data.

[0086] Specifically, patients can follow the audio and video content to perform synchronous inhalation, breath holding, exhalation and relaxation. The breath holding training action needs to be repeated 3 times or more. The sensor module synchronously detects the patient's breath holding situation, including the amplitude of abdominal wall movement during breath holding, the longest breath holding time, etc., and synchronizes the data to the control module. Based on the results of multiple training sessions, a comprehensive judgment is made to assess whether the patient's breath holding quality can be used for breath holding scanning, and a scanning plan is recommended. The scanning plan here is the scanning protocol.

[0087] Step S460: determining a target scanning protocol according to the collected free breathing data and breath-holding data.

[0088] Specifically, due to the different acceleration technologies of magnetic resonance scanning, the duration of a single magnetic resonance breath-holding protocol varies, so the duration of a single breath-holding session generally needs to be 12s, 15s, 18s and 20s. When the breath-holding quality is good, the control module can select scanning protocols with different breath-holding durations as the target scanning protocol for scanning according to the patient's breath-holding time; when the patient's breath-holding quality is poor, such as the breath-holding time is too short or there is still a large amplitude abdominal wall movement during breath-holding, but the quality of steady breathing (i.e., free breathing) is high, the triggered scanning protocol is selected as the target scanning protocol for scanning; when both the breath-holding quality and the steady breathing quality are poor, the user is prompted with the risk of scanning failure (such as the risk of respiratory artifacts in the image).

[0089] Step S470: Perform magnetic resonance scanning according to the determined target scanning protocol.

[0090] Specifically, when the breath-hold scanning protocol is selected for scanning, the control module outputs the breath-holding audio and video file and the countdown projection to the audio and video playback module according to the duration of a single breath-holding protocol. Before the scan starts, the patient is prompted to follow the breath-holding action in the audio and video to keep in sync. The countdown prompt can relieve the patient's tension caused by the lack of a concept of time during the scan, and better cooperate with the examination. The breath-holding action projected in the aperture can prompt the patient to better cooperate with the examination, and can also help hearing-impaired patients complete the breath-holding examination. When the trigger scanning protocol is selected for scanning, the control module can output relaxing audio and video to help patients relieve tension and better cooperate with the examination.

[0091] In this embodiment, the control module sets a breathing training program and sends it to the audio and video playback module. The audio and video playback module plays the breathing training program to guide the user to perform breathing training synchronously according to the breathing training program played by the audio and video playback module. The sensor module collects the breathing data generated by the user when performing breathing training according to the breathing training program in real time, generates breath holding quality data and free breathing quality data according to the received breathing data, and determines the target scanning protocol according to the breath holding quality data and the free breathing quality data. The scanning protocol generated by the control module is not set based on experience, but is generated based on the breathing data generated by the user after breathing training. This solves the problem in the prior art that the magnetic resonance scanning protocol determined by the magnetic resonance equipment operator based on experience is inappropriate, resulting in low quality of the magnetic resonance image.
