Description

Technical Field

[0001] This application relates to the field of magnetic resonance, and more specifically, to a magnetic resonance data transmission method, apparatus, storage medium, and electronic device. Background Technology

[0002] Before the magnetic resonance imaging (MRI) sequence begins execution, the MRI software needs to translate the pre-defined sequence parameters into hardware execution instructions. Then, all hardware instructions to be executed in this sequence are pre-downloaded into the hardware cache. MRI equipment is designed with a large cache space reserved for storing these instructions. Once all the sequence instructions are cached in the hardware cache, the sequence begins execution, and the sequence parameters cannot be changed during the sequence. Therefore, when sequence parameters need to be updated during the scan, the downlink data channel does not support real-time transmission of sequence parameters.

[0003] In clinical applications, echo navigation technology offers the advantage of real-time data transmission from MRI equipment. Echo navigation measures diaphragmatic movement caused by respiration. Before each sequence command required for imaging is issued, one or more execution commands for the echo navigation module are sent to the hardware to measure the current position of the diaphragm and calculate its location to determine whether to trigger the sequence scan. During sequence execution, there are pauses where callback functions readjust the parameters for the next sequence. Therefore, the current execution method of related technologies—translating sequence parameters into hardware commands before execution and sending all commands to the hardware—cannot meet the requirement of real-time parameter updates during sequence scanning, thus failing to meet the real-time clinical application needs of echo navigation.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0007] Optionally, after receiving the second interrupt request from the second timer, the process includes: determining the storage space required for the uplink data; and storing the uplink data according to the storage space.

[0008] Optionally, determining the storage space required for uplink data includes: determining the quotient of the maximum uplink data transmission rate and the predetermined time; determining the product of the quotient and the execution cycle, the product being the maximum uplink data cache requirement space, and using the maximum uplink data cache requirement space as the storage space.

[0009] Optionally, the preset duration is determined by: determining the first timer period corresponding to the first timer, determining the second timer period corresponding to the second timer; determining the sum of the first timer period and the second timer period; calculating the product of the sum and the preset ratio to obtain the preset duration.

[0012] Optionally, it also includes: a first timer period, a waiting time, and a second timer period constitute a complete execution cycle, wherein the second timer period is longer than the first timer period, and the waiting time is a preset duration.

[0013] Optionally, the method further includes: a first timer cycle starting at the receipt of a first interrupt request and ending at the end of the next data transmission; and a second timer cycle starting at the receipt of a second interrupt request and ending at the end of the previous data upload.

[0014] According to another aspect of the embodiments of this application, a magnetic resonance data transmission device is also provided, comprising: an acquisition module for acquiring downlink data to be sent to a magnetic resonance device; a division module for dividing the downlink data according to an execution cycle to obtain multiple sub-instructions, and sending only one sub-instruction in each execution cycle; a first timer module for transmitting the downlink data in the sub-instruction to the magnetic resonance device in response to a first interrupt request from the magnetic resonance device for the first timer, wherein the downlink data is used to control the magnetic resonance device to scan the object to be scanned; and a second timer module for starting timing at the end of the downlink data transmission, and receiving a second interrupt request from the second timer when the timing duration reaches a preset duration, and sending an indication message allowing the uplink data to be uploaded to the magnetic resonance device in response to the second interrupt request, wherein the uplink data is used to image the object to be scanned.

In response to the second interrupt request, an indication message allowing uplink data to be uploaded is sent to the MRI device. This achieves the purpose of real-time updating of sequence parameters, thereby reducing the time required for the MRI software to recompile hardware instructions according to the sequence parameters after real-time updating of sequence parameters. This solves the technical problem that the execution method in related technologies, which issues all MRI sequence instructions, cannot update parameters in real time during scanning.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] According to an embodiment of this application, a method embodiment for magnetic resonance data transmission is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0028] Figure 1 This is a magnetic resonance data transmission method according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0029] Step S102: Obtain downlink data to be sent to the magnetic resonance imaging device, wherein the downlink data includes hardware instructions;

[0030] Step S104: Divide the downlink data according to the execution cycle to obtain multiple sub-instructions, and send only one sub-instruction in each execution cycle;

[0031] Step S106: In response to a first interrupt request from the magnetic resonance device for the first timer, the downlink data in the sub-instruction is transmitted to the magnetic resonance device, wherein the downlink data is used to control the magnetic resonance device to scan the object to be scanned;

[0032] It is understandable that the object to be scanned is a part of the human body, such as the diaphragm in the process of measuring the movement of the diaphragm caused by breathing.

[0033] Step S108: Start timing at the end of downlink data transmission, and when the timing duration reaches the preset duration, receive a second interrupt request from the second timer. In response to the second interrupt request, send an indication message to the magnetic resonance device allowing uplink data to be uploaded, wherein the uplink data is used to image the object to be scanned.

[0034] In this embodiment, the method of issuing magnetic resonance imaging (MRI) device instructions according to an execution cycle is adopted. Each execution cycle is divided into two timer cycles, and downlink and uplink data are transmitted in the two cycles respectively. Downlink data to be sent to the MRI device is acquired; the downlink data is divided into multiple sub-instructions according to the execution cycle, and only one sub-instruction is sent in each execution cycle; in response to the first interrupt request from the MRI device for the first timer, the downlink data in the sub-instruction is transmitted to the MRI device; timing starts at the end of the downlink data transmission, and when the timing duration reaches the preset duration, a second interrupt request from the second timer is received. In response to the second interrupt request, an indication message allowing uplink data to be uploaded is sent to the MRI device, thereby achieving the purpose of real-time updating of sequence parameters. This reduces the time required for the MRI software to recompile hardware instructions based on the sequence parameters after real-time updating of sequence parameters, and solves the technical problem that the execution method in related technologies, which issues all MRI sequence instructions, cannot update parameters in real time during scanning.

[0035] In some optional embodiments of this application, after receiving a second interrupt request from a second timer, the process includes: determining the storage space required for the uplink data; and storing the uplink data according to the storage space.

[0036] Optionally, determining the storage space required for uplink data includes: determining the quotient of the maximum uplink data transmission rate and the predetermined time; determining the product of the quotient and the execution cycle, the product being the maximum uplink data cache requirement space, and using the maximum uplink data cache requirement space as the storage space.

[0037] It should be noted that the scheduled time is 1 second.

[0038] For example, suppose the execution cycle of Timer 1 is 100µs and the waiting time is 5µs, and the execution cycle of Timer 2 is 900µs. Each alternating execution of Timer 1, the waiting time, and Timer 2 constitutes a complete execution cycle, which is 1005µs. If the maximum uplink data transfer rate is 4Gbps, then the maximum uplink data buffer space required is (4G / 1000000)*1005 = 4.02Mbits.

[0039] Understandably, caching uplink data requires a certain margin of safety, which can be determined by setting the data bit width and cache depth. For example, the data bit width of the uplink cache FIFO can be set to 250K, and the cache depth can be set to 32 bits to meet the caching requirements of uplink data in one execution cycle.

[0040] In an exemplary embodiment of this application, the preset duration is determined by: determining the first timer period corresponding to the first timer, determining the second timer period corresponding to the second timer; determining the sum of the first timer period and the second timer period; calculating the product of the sum and a preset ratio to obtain the preset duration.

[0041] It should be noted that the preset ratio is any number within the range of 2% to 5%.

[0042] For example, assuming the execution period of timer 1 is 100us, the execution period of timer 2 is 900us, and the preset value is 5%, then the waiting time is 5us.

[0043] As an optional implementation, the method further includes: the transmission priority of downlink data is greater than the transmission priority of uplink data.

[0044] It should be noted that downlink data includes, but is not limited to: radio frequency pulse control commands, gradient waveform control commands, and radio frequency received signal acquisition parameters; uplink data includes, but is not limited to: the real and imaginary parts of the digitally quantized magnetic resonance induction signal, hardware status indicators, and hardware anomaly feedback information.

[0045] It should be noted that downlink data refers to data transmission from application software to the driver and magnetic resonance device; uplink data refers to data transmission from the magnetic resonance device to the driver and application software.

[0046] In some optional embodiments of this application, the method further includes: when transmitting downlink data, caching uplink data in the buffer unit of the magnetic resonance device; and uploading uplink data after the downlink data transmission is completed.

[0047] It is understandable that when data is coming down, the magnetic resonance system will prioritize the transmission of downlink data. After the transmission of the current pending instruction is completed, the uplink data that is currently in the hardware waiting queue will be started for uploading. The uplink data is cached in the hardware uplink cache unit.

[0048] In an exemplary embodiment of this application, the method further includes: a first timer period, a waiting time, and a second timer period constituting a complete execution cycle, wherein the second timer period is longer than the first timer period, and the waiting time is a preset duration.

[0049] Optionally, the method further includes: a first timer cycle starting at the receipt of a first interrupt request and ending at the end of the next data transmission; and a second timer cycle starting at the receipt of a second interrupt request and ending at the end of the previous data upload.

[0050] To facilitate a better understanding of the technical solutions of this application by those skilled in the art, a specific embodiment will now be described.

[0051] Figure 2 This is a schematic diagram of a timer implementation according to an embodiment of this application, as shown below. Figure 2 As shown, the timer mainly includes the following steps:

[0052] (1) The magnetic resonance software scans a complete sequence of instructions, and divides the required downlink data into multiple sub-instructions according to the cycle. In each execution cycle, the magnetic resonance software sends a sub-instruction to the magnetic resonance device, wherein the downlink data includes hardware instructions.

[0053] It should be noted that the downlink data sent should not be cached in the hardware instruction cache of the magnetic resonance device for too much data. Specifically, the cache should be less than 256KB and the instruction execution time should not exceed 20ms.

[0054] Understandably, during sequence execution, the MRI device only needs to store a small number of sub-instructions. At the same time, when the MRI sequence needs to adjust the sequence parameters in real time during scanning, the adjusted instructions are subsequently sent to the MRI device cache and executed in real time.

[0055] (2) When Timer 1 (i.e. the first timer mentioned above) starts, the magnetic resonance device sends a timer interrupt request (i.e. the first interrupt request mentioned above) to the magnetic resonance software through the driver, and sends the interrupt request type to the magnetic resonance software, wherein the interrupt request type is Timer 1;

[0056] (3) After receiving the interrupt request (i.e. the first interrupt request mentioned above), the magnetic resonance software will clear the interrupt request (i.e. the first interrupt request mentioned above) and promptly transmit the downlink data in the sub-instruction to be transmitted downlink to the magnetic resonance device.

[0057] It should be noted that downlink data transmission has a higher priority than uplink data transmission.

[0058] It is understandable that when data is coming down, the magnetic resonance system will prioritize the transmission of downlink data. After the transmission of the current pending instruction is completed, the uplink data that is currently in the hardware waiting queue will be started for uploading. The uplink data is cached in the hardware uplink cache unit.

[0059] (4) After the downlink data transmission is completed, wait for a period of time, which is the preset duration mentioned above. The timer period is 2%-5% of the sum of the timer period 1 (i.e. the first timer period mentioned above) and the timer period 2 (i.e. the second timer period mentioned above).

[0060] (5) After the time period ends, timer 2 (i.e. the second timer mentioned above) is started. The magnetic resonance device sends a timer interrupt request (i.e. the second interrupt request mentioned above) to the magnetic resonance software through the driver and sends the interrupt request type to the software, wherein the interrupt request type is timer 2;

[0061] (6) After receiving the interrupt request (i.e. the second interrupt request mentioned above), the magnetic resonance software determines the storage space for receiving uplink data from the hardware and sends an instruction to the magnetic resonance device to allow uplink data transmission through the driver.

[0062] (7) After receiving the instruction, the magnetic resonance equipment transmits the uplink data cached in the hardware uplink cache unit to the magnetic resonance software.

[0063] It should be noted that a complete execution cycle consists of a first timer cycle, a waiting time, and a second timer cycle, which triggers the transmission of downlink and uplink data within a cycle, respectively.

[0064] It is noteworthy that this application issues magnetic resonance equipment instructions according to the execution cycle, decomposes the transmission process of uplink and downlink data into a periodic transmission cycle of uplink and downlink data, and each execution cycle is divided into two timer cycles. The transmission of downlink and uplink data is realized in the two cycles respectively, which satisfies the requirement of real-time update of sequence parameters of magnetic resonance.

[0065] Figure 3 This is a schematic diagram of a magnetic resonance downlink data transmission according to an embodiment of this application, as shown below. Figure 3 As shown, the main steps include the following:

[0066] (1) The magnetic resonance software scans a complete sequence of instructions, and divides the required downlink data into multiple sub-instructions according to the cycle. In each execution cycle, the magnetic resonance software sends a sub-instruction to the magnetic resonance device, wherein the downlink data includes hardware instructions.

[0067] (2) When Timer 1 (i.e. the first timer mentioned above) starts, the magnetic resonance device sends a timer interrupt request (i.e. the first interrupt request mentioned above) to the magnetic resonance software through the driver, and sends the interrupt request type to the magnetic resonance software;

[0068] (3) After receiving the interrupt request (i.e. the first interrupt request mentioned above), the magnetic resonance software will clear the interrupt request (i.e. the first interrupt request mentioned above) and promptly transmit the downlink data in the sub-instruction to be transmitted to the hardware execution unit of the magnetic resonance device. The hardware execution unit can control the magnetic resonance device to scan the object to be scanned.

[0069] Figure 4This is a schematic diagram of magnetic resonance uplink data transmission according to an embodiment of this application, as shown below. Figure 4 As shown, the main steps include the following:

[0070] (1) After the downlink data transmission is completely finished and the waiting time has also ended, acquire the data collected by the magnetic resonance device;

[0071] (2) Start Timer 2 (i.e., the second timer mentioned above), and the magnetic resonance device sends a timer interrupt request (i.e., the second interrupt request mentioned above) to the magnetic resonance software through the driver.

[0072] (3) After receiving the interrupt request (i.e. the second interrupt request mentioned above), the magnetic resonance software determines the storage space for receiving uplink data from the hardware and sends an instruction to the magnetic resonance device to allow uplink data transmission through the driver.

[0073] (4) After receiving the instruction, the magnetic resonance equipment transmits the uplink data cached in the hardware uplink cache unit to the reconstruction processing unit of the magnetic resonance software, wherein the reconstruction processing unit is used to image the part to be tested.

[0074] Figure 5 This is a schematic diagram of the structure of a magnetic resonance data transmission device according to an embodiment of this application, as shown below. Figure 5 As shown, the device includes:

[0075] The acquisition module 50 is used to acquire downlink data to be sent to the magnetic resonance device, wherein the downlink data includes hardware instructions;

[0076] The segmentation module 52 is used to divide the downlink data according to the execution cycle to obtain multiple sub-instructions, and only one sub-instruction is sent in each execution cycle;

[0077] The first timer module 54 is used to respond to a first interrupt request from the magnetic resonance device for the first timer and transmit downlink data in the sub-instruction to the magnetic resonance device, wherein the downlink data is used to control the magnetic resonance device to scan the object to be scanned;

[0078] The second timer module 56 is used to start timing at the end of downlink data transmission, and when the timing duration reaches a preset duration, to receive a second interrupt request from the second timer, and in response to the second interrupt request, to send an indication message to the magnetic resonance device allowing the uplink data to be uploaded, wherein the uplink data is used to image the object to be scanned.

[0079] In this device, the acquisition module 50 is used to acquire downlink data to be sent to the magnetic resonance imaging (MRI) device, wherein the downlink data includes hardware instructions; the partitioning module 52 is used to partition the downlink data according to the execution cycle to obtain multiple sub-instructions, and only one sub-instruction is sent in each execution cycle; the first timer module 54 is used to transmit the downlink data in the sub-instruction to the MRI device in response to a first interrupt request from the MRI device for the first timer, wherein the downlink data is used to control the MRI device to scan the object to be scanned; the second timer module 56 is used to start timing at the end of the downlink data transmission, and when the timing duration reaches a preset duration, to receive a second interrupt request from the second timer, and in response to the second interrupt request, to send an indication message to the MRI device allowing the uplink data to be uploaded, wherein the uplink data is used to image the object to be scanned, thereby achieving the purpose of real-time updating of sequence parameters. This achieves the technical effect of reducing the time required for the MRI software to recompile hardware instructions according to the sequence parameters after real-time updating of sequence parameters, and thus solves the technical problem that the parameters cannot be updated in real time during the scanning period due to the execution method of sending all MRI sequence instructions in related technologies.
