It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The method for detecting the radio frequency board card provided by the embodiment of the application can be applied to computer equipment shown in fig. 1. The computer device comprises a processor and a memory connected by a system bus, wherein a computer program is stored in the memory, and the steps of the method embodiments described below can be executed when the processor executes the computer program. Optionally, the computer device may further comprise a network interface, a display screen and an input device. Wherein the processor of the computer device is configured to provide computing and control capabilities. The memory of the computer device includes a nonvolatile storage medium storing an operating system and a computer program, and an internal memory. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The network interface of the computer device is used for communicating with an external terminal through a network connection. Optionally, the computer device may be a server, a personal computer, a personal digital assistant, other terminal devices such as a tablet computer, a mobile phone, and the like, or a cloud or a remote server, and the specific form of the computer device is not limited in the embodiment of the present application.

In an embodiment, as shown in fig. 2, a method for detecting a radio frequency board is provided, which is described by taking the method as an example applied to the computer device in fig. 1, and includes the following steps:

s201, sending a control instruction to a radio frequency board card according to a preset protocol instruction; the control instruction is used for instructing the radio frequency board card to repeatedly send a fixed radio frequency signal.

The fixed radio-frequency signals repeatedly sent by the radio-frequency board card are radio-frequency signals with the same signal waveform. It should be noted that the radio frequency board card has a fixed transmission signal interval under the same instruction, that is, the transmission signal intervals of the radio frequency board card under the same instruction are the same. Specifically, the computer device sends a control instruction to the radio frequency board card according to a preset protocol instruction, and instructs the radio frequency board card to repeatedly send a fixed radio frequency signal through the control instruction. Optionally, the preset protocol command may include information such as a time interval for sending the control command.

S202, acquiring feedback data through an acquisition board card; the feedback data is corresponding to the radio frequency signal.

Specifically, the computer device acquires feedback data corresponding to the radio frequency signal through the acquisition board card. Optionally, the time interval for acquiring the feedback data can be written in the acquisition board card, that is, the acquisition of the feedback data is performed once according to the time interval. It will be appreciated that the radio frequency signals correspond to feedback data, i.e. one radio frequency signal corresponds to one feedback data. It should be noted that, as shown in fig. 2a, the feedback data refers to data generated by the acquisition board processing the received protocol command according to the service logic, once the data is generated, the acquisition board will modify the designated register to notify the upper layer software, and after the protocol command is issued, the detection program will read the designated register at a frequency of every 50us until all the data in the DMA of the acquisition board is transferred to the memory.

And S203, obtaining the phase value of each channel of the magnetic resonance equipment and the amplitude value of each channel of the magnetic resonance equipment according to the feedback data.

Specifically, the computer device obtains a phase value of each channel of the magnetic resonance device and an amplitude value of each channel of the magnetic resonance device according to the obtained feedback data. Optionally, the computer device may analyze the acquired feedback data through a preset algorithm to obtain a phase value of each channel of the magnetic resonance device and an amplitude value of each channel of the magnetic resonance device.

And S204, obtaining a detection result of the radio frequency board card according to the phase value of each channel of the magnetic resonance equipment and the amplitude value of each channel of the magnetic resonance equipment.

Specifically, the computer device obtains the detection result of the radio frequency board according to the obtained phase value of each channel of the magnetic resonance device and the obtained amplitude value of each channel of the magnetic resonance device, that is, the computer device may obtain the detection result of the radio frequency board by using the method shown in fig. 2 b. Optionally, the computer device may compare the phase value of each channel of the magnetic resonance device with a preset phase threshold, and compare the amplitude of each channel of the magnetic resonance device with a preset amplitude threshold, to obtain the detection result of the radio frequency board. It can be understood that the detection result of the radio frequency board card obtained here includes whether the hardware device of the radio frequency board card is intact, whether the service function of the radio frequency logic receiving/analyzing instruction and the radio frequency transmitting signal is intact, and the like, and the detection range of the radio frequency board card may include whether the power supply voltage state of the hardware device of the radio frequency board card is normal, whether the temperature heat dissipation is abnormal, whether the calibration parameter is matched, whether the radio frequency transmitting link path is abnormal, and the like.

According to the detection method of the radio frequency board card, the computer device sends the control instruction to the radio frequency board card according to the preset protocol instruction, and can instruct the radio frequency board card to repeatedly send the fixed radio frequency signal, so that feedback data corresponding to the radio frequency signal can be acquired through the acquisition board card, the phase value of each channel of the magnetic resonance device and the amplitude of each channel of the magnetic resonance device can be acquired according to the feedback data, and further, the detection result of the radio frequency board card can be acquired according to the phase value of each channel of the magnetic resonance device and the amplitude of each channel of the magnetic resonance device.

In the scenario that the detection result of the radio frequency board is obtained according to the phase value of each channel of the magnetic resonance device and the amplitude value of each channel of the magnetic resonance device, in an embodiment, the step S204 includes: and obtaining a detection result of the radio frequency board card according to the phase value and the preset phase range of each channel of the magnetic resonance equipment and the amplitude and the preset amplitude range of each channel of the magnetic resonance equipment.

Specifically, the computer device obtains the detection result of the radio frequency board card according to the obtained phase value and preset phase range of each channel of the magnetic resonance device, and the obtained amplitude value and preset amplitude range of each channel of the magnetic resonance device. Optionally, the computer device may compare the phase value of each channel of the magnetic resonance device with a preset phase range to obtain a first comparison result, compare the amplitude value of each channel of the magnetic resonance device with a preset amplitude range to obtain a second comparison result, and if the first comparison result indicates that the phase value of each channel of the magnetic resonance device is within the preset phase range and the second comparison result indicates that the amplitude value of each channel of the magnetic resonance device is within the preset amplitude range, the computer device determines that the detection result of the radio frequency board card passes. It can be understood that, if one of the phase values of each channel of the magnetic resonance device is not within the preset phase range, or if one of the amplitude values of each channel of the magnetic resonance device is not within the preset amplitude range, the computer device determines that the detection result of the radio frequency board is failed, and exemplarily, the computer device may obtain the detection result of the radio frequency board according to the phase value and the preset phase range of each channel of the magnetic resonance device, and the amplitude value and the preset amplitude range of each channel of the magnetic resonance device by using the method shown in fig. 3.

In this embodiment, the process of obtaining the detection result of the radio frequency board card by the computer device according to the phase value and the preset phase range of each channel of the magnetic resonance device and the amplitude and the preset amplitude range of each channel of the magnetic resonance device is relatively simple, and other operations are not required, so that the detection result of the radio frequency board card can be quickly obtained, and the efficiency of obtaining the detection result of the radio frequency board card is improved.

In the above scenario of obtaining the phase values of the channels of the magnetic resonance apparatus and the amplitude values of the channels of the magnetic resonance apparatus according to the feedback data, in an embodiment, as shown in fig. 4, the step S203 includes:

s401, analyzing the feedback data to obtain sampling point data corresponding to the feedback data.

Specifically, the computer device analyzes the feedback data corresponding to the radio frequency signal to obtain sampling point data corresponding to the feedback data. It should be noted that, as shown in fig. 4a, the format of the rf data is composed of several rows, each row represents data of two sampling points, each two rows of data form a line, and each 128 lines form data of one channel. For example, as shown in fig. 4b, the computer device may first read a row of data, determine which line the current data belongs to, then determine which channel the current line belongs to, and then analyze a specific sampling point of the current row of data to obtain sampling point data corresponding to the feedback data.

S402, obtaining a phase value of each channel of the magnetic resonance equipment and an amplitude value of each channel of the magnetic resonance equipment according to the sampling point data.

Specifically, the computer device obtains the phase value of each channel of the magnetic resonance device and the amplitude value of each channel of the magnetic resonance device according to the sampling point data corresponding to the obtained feedback data. Optionally, the computer device may obtain the phase value of each channel of the magnetic resonance device according to the sampling point data corresponding to the obtained feedback data and a preset phase calculation formula, and obtain the amplitude value of each channel of the magnetic resonance device according to the sampling point data corresponding to the obtained feedback data and a preset amplitude calculation formula. Alternatively, the computer device may obtain the phase value of each channel of the magnetic resonance device and the amplitude value of each channel of the magnetic resonance device by using a phase calculation formula and an amplitude calculation formula shown in the following table.

Preconditions	The radio frequency emission flip angle is 90 degrees
		Breadth table adopted range	Starting from the 50 th point
Range of phase meter	Starting from the 50 th point
		Formula for calculating amplitude	Real square + imaginary square, and result re-squared
Formula for phase calculation	atan2 (imaginary part, real part 180/pi), (-pi.)

For example, assuming that the expression of the sampling point data is a + ib, where a represents the real part of the sampling point data and b represents the imaginary part of the sampling point data, the phase value of each channel of the magnetic resonance apparatus can be expressed as c ═ atan as shown by the amplitude calculation formula and the phase calculation formula in the above table²(a, b 180/pi), wherein c represents the phase value of each channel of the magnetic resonance equipment, and a represents the real part of the sampling point dataB denotes the imaginary part of the sampling point data, and the amplitude of each channel of the magnetic resonance apparatus can be expressed asIn the formula, f represents a phase value of each channel of the magnetic resonance device, a represents a real part of the sampling point data, and b represents an imaginary part of the sampling point data.

In this embodiment, the computer device may analyze the feedback data corresponding to the radio frequency signal, and quickly obtain sampling point data corresponding to the feedback data, and further quickly obtain the phase value of each channel of the magnetic resonance device and the amplitude value of each channel of the magnetic resonance device according to the sampling point data corresponding to the feedback data, so that the efficiency of obtaining the phase value of each channel of the magnetic resonance device and the amplitude value of each channel of the magnetic resonance device is improved.

In the above scenario where the detection result of the radio frequency board is obtained according to the phase value and the preset phase range of each channel of the magnetic resonance device, and the amplitude and the preset amplitude range of each channel of the magnetic resonance device, it is necessary to first determine the preset phase range and the preset amplitude range, and in an embodiment, as shown in fig. 5, the method further includes:

s501, sending a sample control instruction to a sample radio frequency board card for multiple times according to a preset protocol instruction;

optionally, the computer device may select a radio frequency board card which is scanned for a preset time length in a scanning environment and is not abnormal as a sample radio frequency board card, and send a sample control instruction to the sample radio frequency board card for multiple times according to the preset protocol instruction, so as to instruct the sample radio frequency board card to repeatedly send a fixed sample radio frequency signal. It should be noted that, in this embodiment, the sample control instruction instructs the sample rf board to repeatedly send the fixed sample rf signal as the sample rf signal with the same waveform.

And S502, acquiring sample feedback data corresponding to the sample control command sent each time.

Specifically, the computer device obtains sample feedback data corresponding to the sample control instruction sent each time. Optionally, the computer device may obtain, through the acquisition board card, sample feedback data corresponding to the sample control instruction sent each time. It is to be understood that the sample feedback data corresponds to the sample control commands one to one, i.e. one sample control command corresponds to one sample feedback data.

And S503, analyzing the sample feedback data to obtain sample sampling point data corresponding to the sample feedback data.

Specifically, the computer device analyzes the sample feedback data corresponding to the sample control instruction sent each time to obtain sample sampling point data corresponding to each sample feedback data. Optionally, the computer device may first read a line of data in the sample feedback data, determine which line the current sample feedback data belongs to, determine which channel the current line belongs to, and then analyze a specific sampling point of the current line of data to obtain sample sampling point data corresponding to the sample feedback data.

S504, obtaining a preset phase range and a preset amplitude range according to the sampling point data of each sample.

Specifically, the computer device obtains the preset phase range and the preset amplitude range according to the obtained data of each sample sampling point. Optionally, as shown in fig. 5a, the computer device may determine a maximum phase value in the phase values corresponding to the sample sampling point data as a maximum boundary value of the preset phase range, and determine a minimum phase value in the phase values corresponding to the sample sampling point data as a minimum boundary value of the preset phase range; and determining the maximum amplitude value of the amplitude values corresponding to the sample sampling point data as the maximum boundary value of the preset amplitude value range, and determining the minimum amplitude value of the amplitude values corresponding to the sample sampling point data as the minimum boundary value of the preset amplitude value range.

In this embodiment, the computer device can send the sample control instruction to the sample radio frequency board card for multiple times according to the preset protocol instruction, so that sample feedback data corresponding to the sample control instruction sent each time can be quickly obtained, and then each sample feedback data can be analyzed, sample sampling point data corresponding to each sample feedback data can be quickly obtained, then the preset phase range and the preset amplitude range can be quickly obtained according to each sample sampling point data, and the efficiency of obtaining the preset phase range and the preset amplitude range is improved.
