Examples
As shown in fig. 1 to 3, the present embodiment discloses a scanning system for magnetic resonance examination for limiting the movement of a patient, which includes a position limiter sensor, a voice prompt device, a magnetic resonance image acquisition system and a processor, wherein the position limiter sensor is disposed on a magnetic resonance worktable and is detachably connected to the magnetic resonance worktable; the voice prompt equipment is arranged in the magnetic resonance examination room and does not influence the position of the magnetic resonance magnetic field environment; the processor comprises a reminding unit and a magnetic resonance image acquisition intelligent decision-making system, the reminding unit is in data connection with the voice reminding device, and the magnetic resonance image acquisition intelligent decision-making system is in data connection with the limiter sensor; the magnetic resonance image acquisition system is in data connection with the processor, and the magnetic resonance image acquisition system, the limiter sensor, the voice prompt device and the processor are respectively connected with the power supply structure through leads.
Firstly, the magnetic resonance imaging task is ordered and sequenced, and an image acquisition time sequence is established. After image acquisition starts, a time sequence is shared by the magnetic resonance image acquisition system, the magnetic resonance image acquisition intelligent decision system and the magnetic resonance image acquisition key moment reminding system, and a doctor determines a time sequence point of the image acquisition key moment. In the working process, the position information of the patient is received by the position limiter sensor in real time, when the patient moves, the information of the time sequence point is marked, and the image of the marked time sequence point is collected again after the patient keeps still and the data of the position limiter sensor is not changed. When the time sequence reaches the key moment marked by the doctor, the system informs the patient to keep still through the voice prompt device. When the data of the sensor of the position limiter is monitored to be changed violently or for a long time in the image acquisition process, a doctor is informed to placate the emotion of the patient. Therefore, the acquisition precision of the magnetic resonance image cannot be reduced due to the movement of the patient in the acquisition process.
In a typical application of the present application, as shown in fig. 2, there are 9 limit rods of the limit sensor 1 placed according to the position 4 of the limit sensor on the magnetic resonance worktable, the limit rods are above the magnetic resonance imaging worktable 3, and the limit sensor integration part 2 is located below the worktable 3. The movement of a patient can be sensed through the swinging of the limiting rod 1, an electric signal is transmitted to the computer terminal, and whether the image is collected again or not is controlled by the magnetic resonance image collection intelligent decision-making system so as to ensure the precision.
In a specific embodiment, the limiting rod of the limiter sensor is made of plastic or silica gel, so that the magnetic resonance magnetic field is not interfered while the hardness is ensured, the initial position of the limiting rod is inverted to the lying direction of a patient, the direction of the patient is taken as the initial zero point of the limiting rod, and current and voltage changes can be generated when the limiting rod moves in the opposite direction so as to sense the posture change condition of the patient.
The limiter sensor integration part 2 has metal or a power supply, which can affect the magnetic resonance magnetic field, and the part is placed under the workbench to avoid affecting the image acquisition process.
The gag lever post position of stopper sensor 1 is confirmed, and the action that the aim at overall monitoring patient placed on the workstation changes, when a certain or a plurality of 1 numerical value of stopper sensor change, just think that the patient has taken place to remove.
The magnetic resonance image acquisition system, the magnetic resonance image acquisition intelligent decision-making system and the magnetic resonance image acquisition key moment reminding system share a time sequence, the time sequence is the acquisition sequence of the magnetic resonance images, when the image acquisition plan is determined, the acquisition time sequence can be automatically generated, and the three systems share the time sequence.
When the image acquisition plan is determined, a doctor can determine an acquisition key time sequence point, and when the acquisition process reaches the time sequence point, the magnetic resonance image acquisition key time reminding system triggers the voice reminding device to remind a patient to hold breath or other preset instructions in advance.
The magnetic resonance image acquisition intelligent decision-making system monitors the numerical values of the 9 limiter sensors 1 in real time, relevant threshold values are reserved, when the body position of a patient changes due to breathing or heartbeat, the magnetic resonance imaging system can work normally, and the magnetic resonance image acquisition intelligent decision-making system cannot be triggered.
When the numerical value change of the limiter sensor 1 exceeds a threshold value, the magnetic resonance image acquisition intelligent decision-making system is triggered, the system can record an image acquisition time sequence point, and when the patient is prompted to keep still and the data of the limiter sensor is unchanged, the marked image acquisition process can be automatically acquired again.
When one or more stopper sensor data, when increasing substantially or the persistence change, just can trigger the mood and pacify warning system, remind the doctor to pacify the patient mood, guarantee the high accuracy of image and gather.
The specific process used is as follows:
after the image acquisition plan of the patient is determined, the magnetic resonance image acquisition time sequence of the patient is determined according to the acquisition plan, the magnetic resonance image acquisition system, the magnetic resonance image acquisition intelligent decision-making system and the magnetic resonance image acquisition key moment reminding system share one time sequence, and a doctor marks an image acquisition key point in the image acquisition time sequence.
Firstly, a patient lies on a workbench according to a positioning method required by magnetic resonance image acquisition, 9 limiting rods are placed on the patient body, the limiting rods are made to be attached to the patient body, and then a doctor returns to an operation room and starts image acquisition.
After image acquisition begins, a plurality of magnetic resonance images are acquired according to time sequence setting, meanwhile, the limiter sensor 1 begins to transmit back limiting data, the magnetic resonance image acquisition intelligent decision-making system monitors the numerical values of 9 limiter sensors in real time, when the numerical value changes beyond a threshold value, the magnetic resonance image acquisition intelligent decision-making system is triggered, and at the moment, the magnetic resonance image acquisition intelligent decision-making system records the position of a time sequence point. And the second prompter prompts the patient to keep still and the marked time sequence point image to be resampled after the data of the sensor 1 of the limiter is stabilized.
When the magnetic resonance image acquisition time sequence reaches the key time set by a doctor, the magnetic resonance image acquisition key time reminding system is triggered, and the voice reminding device informs the patient of holding breath or other preset instructions.
The magnetic resonance sets up the in-process of gathering the image according to the chronogenesis, and patient's mood pacifies and reminds system parallel operation for monitoring the change of stopper sensor number, when stopper sensor data change or continuously change by a wide margin, judges that patient's mood is unstable, can inform the doctor through the prompter one between the operation and pacify patient's mood.
The method can limit the movement of the patient and ensure the accurate acquisition of the magnetic resonance image.
The above description of the embodiments is only for the understanding of the present invention. It should be noted that modifications could be made to the invention without departing from the principle of the invention, which would also fall within the scope of the claims of the invention.
