Technical Field

[0001] The present invention relates to the technical field of human body monitoring, and in particular to a method and a device for monitoring the movement behavior of a patient during magnetic resonance surgery. Background Art

[0002] MRI surgery needs to be performed under the guidance of magnetic resonance imaging (MRI), so the patient needs to remain relatively still during the operation to ensure that the surgical tool can be accurately positioned and controlled. However, due to various reasons (such as breathing, heartbeat, discomfort, etc.), the patient may move during the operation, resulting in surgical failure.

[0003] In order to solve this problem, during the operation, medical staff should closely observe and monitor the patient's breathing, heartbeat and other vital signs, and promptly detect the patient's movement so that measures can be taken to correct it in time. However, this requires medical staff to pay close attention to the patient, so that they cannot fully focus on the operation process, which poses certain safety risks. Summary of the invention

[0004] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0009] Based on a preset mapping relationship, determining a second movement level corresponding to the movement range;

[0010] Determining a third movement level corresponding to the patient based on measurement information measured by an inertial sensor installed on the patient;

[0011] Whether the movement behavior of the patient has hidden dangers is determined according to the first movement level, the second movement level, and the third movement level.

[0012] The second aspect of the present disclosure provides a device for monitoring the movement behavior of a patient during magnetic resonance surgery, comprising:

[0014] A first judgment module, used for judging a first movement level corresponding to the patient according to each of the vital sign information and the corresponding reference information;

[0015] A second acquisition module is used to acquire a first image of the patient during the operation, and compare the first image with a preset reference image to determine a corresponding movement range of the patient;

[0016] A determination module, configured to determine a second movement level corresponding to the movement range based on a preset mapping relationship;

[0019] The third aspect embodiment of the present disclosure proposes an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the method for monitoring the movement behavior of a patient during magnetic resonance surgery proposed in the first aspect embodiment of the present disclosure is implemented.

[0020] The fourth aspect embodiment of the present disclosure proposes a non-temporary computer-readable storage medium storing a computer program, which, when executed by a processor, implements the method for monitoring the movement behavior of a patient during magnetic resonance surgery as proposed in the first aspect embodiment of the present disclosure.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0028] The following describes a method and apparatus for monitoring patient movement behavior during magnetic resonance surgery according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0029] Figure 1A schematic flow chart of a method for monitoring patient movement behavior during magnetic resonance surgery provided in the first embodiment of the present disclosure.

[0030] like Figure 1 As shown, the method for monitoring the movement behavior of a patient during magnetic resonance surgery may include the following steps:

[0031] Step 101 : acquiring various vital sign information of the patient based on multiple monitoring devices worn by the patient during magnetic resonance imaging surgery.

[0032] Optionally, the multiple monitoring devices worn by the patient include at least:

[0033] ECG electrodes worn on the patient's chest:

[0034] Cuffs, finger clips, ear clips, chest straps, endotracheal tubes, thermometers,

[0035] The various vital sign information at least includes electrocardiogram waveform, systolic blood pressure, diastolic blood pressure, blood oxygen saturation, respiratory rate, respiratory depth and body temperature.

[0036] It should be noted that the electrocardiogram electrodes are electrocardiogram electrodes worn on the patient's chest and can be used to record electrocardiogram waveforms to monitor the electrical activity and heart rate of the heart.

[0037] Blood pressure monitoring devices are blood pressure monitoring devices such as cuffs, finger clips or chest straps that can obtain the patient's systolic and diastolic blood pressure to evaluate blood pressure changes and cardiovascular system function.

[0038] Blood oxygen saturation monitoring equipment uses devices such as finger clips to monitor the patient's blood oxygen saturation, that is, the oxygen content in the blood, in real time to assess the patient's breathing and oxygen supply conditions.

[0039] Respiratory rate monitoring equipment can use breathing belts, endotracheal tubes and other equipment to monitor the patient's respiratory rate and breathing depth to understand respiratory function and lung condition.

[0040] Temperature monitoring equipment, such as thermometers, can be used to monitor a patient's temperature and how it changes over time.

[0041] Through these monitoring devices, the patient's vital signs such as electrocardiogram waveform, systolic blood pressure, diastolic blood pressure, blood oxygen saturation, respiratory rate, respiratory depth and body temperature can be obtained in real time. This information is very important for evaluating the patient's physiological state, monitoring changes in the condition, and guiding the treatment and surgical process. In magnetic resonance imaging surgery, accurately obtaining and monitoring this information helps to ensure the safety of the patient and the success of the operation.

[0042] Step 102: Determine the first movement level corresponding to the patient according to each vital sign information and corresponding reference information.

[0043] It should be noted that the reference interval can be determined first, and for each vital sign information, the reference interval can be determined based on the corresponding reference information. These reference intervals are used to characterize the range of discomfort that makes the user feel, such as electrocardiogram waveform, systolic blood pressure, diastolic blood pressure, blood oxygen saturation, respiratory rate, respiratory depth and body temperature, etc., and then the vital sign information can be compared with the reference interval, and each vital sign information actually measured can be compared with its corresponding reference interval. Check whether the index value is within the reference interval.

[0044] According to the comparison results, multiple judgment results are obtained, that is, whether the index value is within the corresponding reference interval is judged. For each vital sign information, the judgment result is whether the index value is within the reference interval, which can be expressed as satisfied or not satisfied.

[0045] The specified number can be 2 or 3, which is not limited here.

[0046] According to the requirements, if the specified number of judgment results all meet the condition that the index value is within the corresponding reference interval, the first movement level is determined to be the first level. Otherwise, the first movement level is the second level.

[0047] Electrocardiogram waveform: For electrocardiogram waveform, usually, some abnormal waveform features such as too fast heart rate, too slow heart rate, irregular heartbeat, etc. may make the user feel uncomfortable. Specifically, abnormal or irregular changes in features such as P wave, QRS wave and T wave in the electrocardiogram may cause discomfort.

[0048] Systolic and diastolic blood pressure: Changes in blood pressure within the normal range usually do not cause discomfort, but if blood pressure is too high or too low, it may cause uncomfortable symptoms such as dizziness, headache, and chest tightness.

[0049] Blood oxygen saturation: Normal range of blood oxygen saturation will not cause discomfort in most cases. However, if the blood oxygen saturation is too low, for example, below 90%, it may cause discomfort such as difficulty breathing, palpitations, headaches, etc.

[0050] Respiratory rate and depth: Within the normal range, respiratory rate and depth usually do not cause noticeable discomfort. However, abnormal respiratory rate (too fast or too slow) or breathing depth may cause symptoms such as difficulty breathing, shortness of breath, or sweating.

[0051] Body temperature: A body temperature within the normal range does not usually cause discomfort. However, when the body temperature is too high (fever) or too low (hypothermia), the patient may experience discomfort, such as chills or sweating.

[0052] It should be noted that the above description is only a general observation and explanation of these vital signs in general. Through the above process, the first movement level can be determined according to the reference interval of each vital sign information and the judgment result compared with the reference interval. This level division can be used to comprehensively evaluate the vital sign information and take appropriate treatment measures when necessary, such as adjusting the treatment plan or taking corresponding intervention measures.

[0053] It should be noted that the specific determination of parameter intervals and specified quantities can be defined and explained in advance by professional medical staff in this field, and can be formulated according to specific circumstances and actual needs, and determined according to the reference range of medical professional institutions and individual actual conditions.

[0054] Step 103 , obtaining a first image of the patient during the operation, and comparing the first image with a preset reference image to determine the corresponding movement range of the patient.

[0055] Specifically, during the operation, the first image of the patient during the operation can be captured in real time based on a camera device, wherein the camera device can be any device with a camera function.

[0056] The reference image may be a reference image determined before the operation based on the individual characteristics of the patient. If the patient's body position coincides with the body position in the reference image, it means that it is normal at this time. The greater the deviation between the patient in the first image and the reference image, the greater the patient's range of movement.

[0057] By comparing the first image with a preset reference image, the difference and similarity between the two images can be compared for the structure or region of interest, and the range of movement can be quantitatively evaluated.

[0058] By comparing the first image with the reference image, the extent of the patient's movement during surgery can be assessed. Depending on the size and location of the difference, it can be determined whether the patient has unexpectedly moved or deviated during surgery.

[0059] Step 104: Determine a second movement level corresponding to the movement range based on a preset mapping relationship.

[0060] It should be noted that the movement levels corresponding to the areas of different movement ranges can be pre-established. If the area corresponding to the movement range is larger, the second movement level is higher, and if the area corresponding to the movement range is smaller, the second movement level is lower, and the patient moves less severely.

[0061] Step 105 : determining a third movement level corresponding to the patient based on measurement information measured by an inertial sensor installed on the patient.

[0062] Specifically, the first measurement information and the second measurement information may be acquired based on an accelerometer and a gyroscope installed on the patient.

[0063] An accelerometer measures the acceleration of an object in space, that is, the relationship between the acceleration of an object and the external force it is subjected to. It is usually achieved by measuring the acceleration of an object in three axes (x, y, z). An accelerometer can be used to detect linear acceleration, vibration, tilt and other movements of an object. The first measurement information is acceleration.

[0064] A gyroscope measures the angular velocity or rotation rate of an object. It can sense the speed and direction of an object's rotation around three axes. Gyroscopes usually provide information about attitude changes, such as rotation, turning, and swinging of an object, by measuring the angular velocity of the object (the rotation rate around the x, y, and z axes). The second measurement information is the angular velocity.

[0065] The patient's body movement status information during the operation is obtained through sensors such as accelerometers and gyroscopes. These sensors can measure the patient's acceleration, angular velocity and other data.

[0066] Before or during surgery, obtain a reference or fiducial point measurement. Reference measurements can be made by recording the patient's acceleration and angular velocity when the patient is stationary or in a specific position.

[0067] The first measurement information and the second measurement information are compared with the reference measurement information. By analyzing the differences, change trends, etc. between the acceleration and angular velocity data and the reference measurement information, the movement of the patient during the operation can be evaluated.

[0068] Determining the third movement level: According to the comparison result and the pre-set judgment standard, the third movement level corresponding to the patient can be determined.

[0069] The first difference between the acceleration and the corresponding reference acceleration and the second difference between the angular velocity and the corresponding reference angular velocity are compared respectively, and then the scores corresponding to the first difference and the second difference can be determined respectively, and weighted addition is performed. Finally, the higher the score is, the greater the third movement level is, which means that the patient's movement is more violent.

[0070] Step 106: judging whether the patient's movement behavior has hidden dangers according to the first movement level, the second movement level and the third movement level.

[0071] Optionally, when the first movement level is the first level and the second movement level is greater than the first threshold, it is determined that the patient's movement behavior has hidden dangers;

[0072] When the first movement level is the first level and the third movement level is greater than the second threshold, determining that the patient's movement behavior has a hidden danger;

[0073] When the first movement level is the second level, the second movement level is greater than the first threshold, and the third movement level is greater than the second threshold, it is determined that the patient's movement behavior has hidden dangers.

[0074] It should be noted that the higher the second and third movement levels are, the larger the patient's movement range is, the more intense the movement behavior is, and thus there are hidden dangers. If the first movement level is the first level, it means that the patient is unwell. If the patient's second movement level is greater than the first threshold, or the third movement level is greater than the second threshold, it means that the patient's movement behavior is relatively intense, and an early warning can be issued at this time.

[0075] Alternatively, if the patient's first movement level is the second level, it means that the patient does not feel uncomfortable, but the patient's second movement level is greater than the first threshold, and the third movement level is greater than the second threshold, it means that the patient's movement behavior is very intense at this time, which poses a great hidden danger and requires an early warning.

[0076] If it is determined that the patient's movement behavior poses a hidden danger, an alarm can be sounded through a buzzer, or the early warning indicator light in the operating room can be controlled to light up.

[0077] In the disclosed embodiment, firstly, the patient's various vital signs information is obtained based on multiple monitoring devices worn by the patient during the magnetic resonance surgery, then the first movement level corresponding to the patient is determined according to each of the vital signs information and the corresponding reference information, then the first image of the patient during the surgery is obtained, and the first image is compared with the preset reference image to determine the movement range corresponding to the patient, then the second movement level corresponding to the movement range is determined based on the preset mapping relationship, and finally the third movement level corresponding to the patient is determined based on the measurement information measured by the inertial sensor installed on the patient, and then the patient's movement behavior is determined according to the first movement level, the second movement level and the third movement level. Thus, the patient's movement state can be determined in an all-round way in three dimensions by combining the patient's multiple physiological characteristics information, the information measured by the inertial sensor and the patient's image information, and then it can be determined whether the patient has a large movement, and timely warning can be given to prevent affecting the doctor's surgery and causing harm to the patient, thereby reducing the doctor's work difficulty, allowing the doctor to concentrate on the surgery and ensure the smooth progress of the surgery.
