The standard test results of various test tasks are stored in the calibration submodule.

[0028] When there are multiple test tasks in a test plan, the multiple test tasks are sorted according to a preset sequence.

[0029] This embodiment is configured in such a way that each test sub-item can be executed in sequence according to a predetermined order, and each sub-item has a highly intelligent function.

[0030] In order to realize automatic testing of the magnetic resonance scanning device, in this embodiment, the coordination action process includes: S1, the control submodule controls the test tool submodule to generate corresponding test instructions according to the first test task in the test plan; S2, the control submodule controls the communication submodule to send the test instruction to the magnetic resonance scanning device; S3, the magnetic resonance scanning device performs a scanning test according to the test instruction to obtain scanning test result data; S4, the control submodule controls the communication submodule to obtain the scan test result data, and controls the image analysis and data processing submodule to perform image and data analysis on the scan test result data to obtain the test result; S5, the control submodule controls the calibration submodule to determine whether the scanning test corresponding to the current test task is completed according to the test results and the corresponding standard test results; if so, enter S6; S6, the control submodule determines whether there is a next test task in the test plan; if so, the control submodule controls the test tool submodule to generate a corresponding test instruction according to the next test task and enter S2; if not, enter S7; S7.

[0031] This embodiment is configured so as to effectively and automatically complete the testing of each test task in the test plan in sequence, greatly shortening the test time, reducing the manual operation links, reducing the interference of human factors, improving work efficiency, avoiding errors caused by inaccurate manual parameter settings and subjective judgment differences, and improving the accuracy of scanning results and analytical diagnosis.

[0032] Moreover, it reduces the reliance on professional operators and reduces labor costs. At the same time, it improves the utilization rate of equipment and reduces the repeated scanning and maintenance costs caused by inaccurate testing.

[0033] In S4, it is determined whether the scanning test corresponding to the current test task is completed; if not, interaction is performed with the human-computer interaction interface to enter S6.

[0034] Among them, in S7, the control submodule also controls the calibration submodule to compare the test results of each test task with the standard test results. When there is a deviation in the comparison result of a test task, a parameter adjustment instruction corresponding to the test task is sent to the magnetic resonance scanning device; the result report generation submodule organizes and formats the test results and comparison results of each test task according to a preset template, and automatically generates a test report containing text description, image display and analysis conclusion.

[0035] It should be understood that during the scanning and imaging process of the magnetic resonance scanning device, control instructions are issued to the gradient module and radio frequency module of the magnetic resonance scanning device according to the received test instructions; the gradient module generates a corresponding gradient magnetic field according to the instructions, and the radio frequency module emits radio frequency pulses of specific frequency and intensity to start scanning; during the scanning process, the magnetic resonance signal collected by the radio frequency receiving coil is amplified by the preamplifier and transmitted to the signal acquisition unit; the signal acquisition unit converts the analog signal into a digital signal, and performs preliminary filtering and noise reduction processing; then, the digital signal is transmitted to the image processing unit, and the image processing unit uses the Fourier transform algorithm to process the digital signal to reconstruct the magnetic resonance image.

[0036] In this embodiment, the test tool submodules include a gradient test unit, a radio frequency test unit, a coil test unit, a phantom test unit, a field uniformity test unit, a laser calibration test unit, a bed control test unit, a system communication test unit and a scanning forming test unit.

[0037] Among them, the test items of the gradient test unit include Gmax value calibration, output voltage, gradient delay, gradient ignition, and eddy current calibration.

[0038] In specific implementation, the gradient test unit is used to send a test instruction including a preset test pulse sequence to the gradient system of the magnetic resonance scanning device through the communication submodule, so as to analyze the performance indicators such as linearity, rise time, and fall time of the gradient system by detecting the output signal of the gradient coil. For example, a high-precision signal acquisition device is used to record the magnetic field changes of the gradient coil under different current intensities, and the image analysis and data processing submodule obtains the signal collected by the signal acquisition device through the communication submodule, and compares the collected signal with the preset standard result (i.e., the theoretical value), so as to determine whether there is a deviation in the gradient system.

[0039] Among them, the test items of the RF system test unit include 90° calibration, RF background noise test and FID signal test.

[0040] In specific implementation, the RF system test unit sends a RF system test instruction to the RF system of the magnetic resonance scanning device, so that the RF signal generator in the RF system sends test signals of different frequencies and powers to the RF transmitting coil of the RF system, and the RF receiving coil receives the reflected signal; the image analysis and data processing submodule obtains the reflected signal through the communication submodule, and evaluates the transmission and receiving performance of the RF system by analyzing the intensity, frequency response and other parameters of the reflected signal. For example, it detects whether the transmission power of the RF system is stable at different frequencies and whether the receiving sensitivity meets the requirements.

[0041] Among them, the test items of the coil test unit include signal-to-noise ratio, uniformity, sensitivity and background noise.

[0042] During specific implementation, for the multi-channel coil of the magnetic resonance scanning device, the coil testing unit is used to send a channel consistency test instruction to the magnetic resonance scanning device through the communication submodule, and apply the same test signal to each channel of the multi-channel coil. The magnetic resonance scanning device synchronously monitors the signal reception of each channel, and the control submodule obtains the performance data such as sensitivity and background noise of each channel of the multi-channel coil of the magnetic resonance scanning device through the communication submodule. The image analysis and data processing submodule evaluates the channel consistency by comparing the performance parameter differences between the channels. For example, check whether the sensitivity deviation of each channel is within the allowable error range. If there is a large difference between the channels, it will cause local signal unevenness or artifacts in the image. The channel consistency test can timely discover and calibrate the differences between channels to ensure the uniformity and accuracy of image quality.

[0043] Among them, the test items of the phantom test unit include signal-to-noise ratio, uniformity, layer thickness, resolution, distortion, and ghosting.

[0044] During specific implementation, the phantom test unit sends a phantom test instruction to the magnetic resonance scanning device. The magnetic resonance scanning device images the phantom by setting specific scanning parameters. The image analysis and data processing submodule collects the region of interest (ROI) through image recognition and calculates the phantom shape, signal strength, etc. to determine whether each parameter meets the preset standards.

[0045] Among them, the test items of the field uniformity test unit include B0, B1, T1, and T2, among which B0 and B1 are magnetic fields, representing the main magnetic field and the radio frequency magnetic field respectively, and T1 and T2 are relaxation times, representing the longitudinal and transverse relaxation times respectively.

[0046] In specific implementation, the field uniformity test unit is used to measure the magnetic field strength at multiple points in the imaging area of ​​the magnetic resonance device using the magnetic field measurement device in the magnetic resonance scanning device, and the image analysis and data processing submodule obtains and analyzes the measured magnetic field strength data through the communication submodule to evaluate the uniformity of the magnetic field. For example, the image analysis and data processing submodule determines whether the field uniformity meets the standard requirements by calculating the magnetic field strength deviation between different measurement points.

[0047] Among them, the laser calibration test unit sends a laser calibration test instruction to the magnetic resonance scanning device through the communication submodule, and the magnetic resonance scanning device performs laser calibration according to the laser calibration test instruction to obtain a scanned image; the image analysis and data processing submodule obtains and analyzes the scanned image through the communication submodule, and compares its shape and size with the size of the actual object, and calculates the position deviation and angle deviation of the bed. The magnetic resonance scanning device automatically adjusts the position and angle of the bed according to the position deviation and angle deviation of the bed to achieve accurate positioning.

[0048] Among them, the test items of the bed control test unit include: configuration function, scanning function, independent function and combination function.

[0049] In specific implementation, the bed control test unit is used to send a series of control instructions, such as movement instructions, lifting instructions, etc., to the bed control system of the magnetic resonance scanning device through the communication submodule to monitor the actual movement of the bed in real time. By comparing the motion parameters required by the instructions with the actual motion parameters of the bed, the accuracy and stability of the bed control system can be judged. For example, check whether the positioning accuracy of the bed during movement is within the allowable range.

[0050] Among them, the system communication test unit is used to detect the communication status between various components in the magnetic resonance scanning equipment. For example, if the communication of a certain device is interrupted, the system communication unit will detect the communication anomaly, issue a warning to discover the problem early, and make corresponding inspections.

[0051] In this embodiment, a storage submodule is also included. The storage submodule is electrically connected to the control submodule. The storage submodule is used to store the test plan so that the generated test plan can be directly selected later.
