Description

Technical Field

[0002] The magnetocardiograph is a new type of heart disease monitoring device that performs imaging analysis by detecting the magnetic field of the human heart. It has the advantages of being completely non-invasive, non-contact, radiation-free, and highly sensitive, and shows good application potential in ischemic heart disease.

[0003] Among them, the measurement methods of magnetic cardiotonic signals are divided into split scanning and one-shot imaging. Split scanning usually achieves time synchronization by synchronously collecting ECG. There are also methods to achieve time synchronization through additional scanning. Although the former is effective, an additional electrocardiograph is added, which brings some inconvenience to the system in terms of equipment cost, system structure, and unstable factors. Although the latter reduces the number of electrocardiographs, the split scanning time is relatively long, and adding additional point scanning prolongs the acquisition time. In this regard, it is very necessary to explore a fast method for synchronizing magnetocardiograph data for the technical development of multi-point scanning magnetocardiographs.

[0049] The technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0050] Specifically, see Figure 2 In one embodiment of the invention, the method for rapid synchronization of magnetocardiograph data of the present invention comprises the following steps:

[0051] Step S202, obtaining a target data volume of a magnetocardiograph array and a number of magnetocardiograph signal channels, wherein the number of magnetocardiograph signal channels includes a basic channel and a reference channel;

[0052] Step S204, determining the number of acquisitions, and sequentially acquiring the magnetocardiographic data based on the number of acquisitions to obtain a maximum amplitude waveform corresponding to each acquired magnetocardiographic data;

[0053] Step S206, determining an R peak based on an average waveform of the maximum amplitude waveforms of the reference channels in adjacent acquisitions, and using the R peak as a reference peak of the current waveform for time translation synchronization;

[0054] Step S208, after time-shift synchronization, the waveforms of all reference channels in each collected magnetocardiographic data are deleted to obtain synchronized target channel data.

[0055] It should be noted that, in this embodiment, first, the acquisition times need to be determined according to the target data volume of the magnetocardiogram array and the number of signal channels of the magnetocardiogram, wherein the number of signal channels of the magnetocardiogram described in this embodiment also includes an additional reference channel compared to the basic channel. Further, after the acquisition times are determined, the magnetocardiogram data can be acquired in sequence based on the acquisition times, wherein the maximum amplitude waveform corresponding to each acquired magnetocardiogram data is obtained based on the signal selective averaging method in the magnetocardiogram signal noise suppression. Since an additional reference channel is added, it is necessary to determine the R peak as the reference peak of the translation based on the average waveform of the maximum amplitude waveform of the adjacent acquired reference channels, so as to use the R peak as the reference peak of the current waveform for time translation synchronization, and after time translation synchronization, delete the waveforms of all the reference channels in each acquired magnetocardiogram data to obtain synchronized target channel data. Among them, using the method disclosed in this embodiment, in actual application, there is no need to acquire additional scanning points and add electrocardiographs. It only needs to add a corresponding number of reference channels in the structure to achieve synchronization of magnetocardiogram data, with fast scanning speed and simple structure. For magnetocardiograms with other channel structures, the method can be deduced by analogy, so it has strong practicality.

[0056] Furthermore, in one embodiment of the invention, the step of obtaining the target data volume of the magnetocardiograph array and the number of magnetocardiograph signal channels specifically includes:

[0057] Acquire the target data volume corresponding to the set magnetocardiographic array data, wherein the target data volume includes 36;

[0058] The number of signal channels of the magnetocardiograph is obtained based on the basic channels of the current magnetocardiograph and the additionally set reference channels, wherein the basic channels include 12 channels and the reference channels include 2 channels.

[0059] It should be noted that, in this embodiment, Figure 3 As shown, the number of signal channels of the magnetocardiograph is displayed, which is specifically 14 channels, wherein the basic channels include 12 channels, corresponding to the serial numbers "1-12", and the reference channels include 2 channels, corresponding to the serial numbers "13-14". Specifically, the target data volume corresponding to the set magnetocardiograph array data is first obtained. In practical applications, the target data volume described in this embodiment includes 36, and the number of magnetocardiograph signal channels is obtained based on the basic channels of the current magnetocardiograph and the additionally set reference channels, which indicates that the magnetocardiograph used in this embodiment is a "12-channel magnetocardiograph" with 2 additional reference channels.

[0060] Further, in an embodiment of the invention, determining the number of acquisitions specifically includes:

[0061] The acquisition times are calculated based on the target data volume and the number of signal channels of the magnetocardiograph, wherein the acquisition times include at least 2 times;

[0062] The target data volume is used as the numerator and the number of channels of the magnetic cardiotoc signal is used as the denominator to perform calculation and round the calculation result to obtain the target value, and the target value is added by one to obtain the number of acquisition times.

[0063] It should be noted that, in this embodiment, due to the existence of time shift, it is necessary to acquire waveforms at least 2 times to determine the shift reference peak, therefore, the acquisition times include at least 2 times, wherein the acquisition times are calculated based on the target data volume and the number of channels of the magnetocardiograph signal. Specifically, the target data volume is used as the numerator, and the number of channels of the magnetocardiograph signal is used as the denominator to calculate and round the calculation result to obtain the target value, and the acquisition times are obtained by adding one to the target value, wherein, in the above embodiment, it is described that the target data volume includes 36, and the number of channels of the magnetocardiograph signal is 14, therefore, the acquisition times corresponding to the application scenario described in the above embodiment is 3 times, wherein the schematic diagram of the 3 acquisition times is as shown in Figure 4 shown.

[0064] Furthermore, in one embodiment of the invention, the magnetocardiographic data are sequentially acquired based on the acquisition times to obtain the maximum amplitude waveform corresponding to each acquired magnetocardiographic data, specifically including: sequentially acquiring the magnetocardiographic data based on the acquisition times to obtain the maximum amplitude waveform, and obtaining the average waveform of the maximum amplitude waveform of the reference channel acquired each time based on a preset method, wherein the preset method includes a signal selective averaging method in magnetocardiographic signal noise suppression.

[0065] It should be noted that, in this embodiment, the maximum amplitude waveform corresponding to the magnetocardiographic data is collected, wherein the average waveform of the maximum amplitude waveform of the reference channel is obtained by using the signal selective averaging method in magnetocardiographic signal noise suppression, wherein the magnetocardiographic data is collected three times in sequence, and each collection needs to obtain the average waveform of the maximum amplitude waveform of the reference channel corresponding to the current collection order.

[0066] Further, in one embodiment of the invention, the R peak is determined based on the average waveform of the maximum amplitude waveforms of the reference channels in adjacent acquisitions, specifically including:

[0067] Extracting an average waveform of the maximum amplitude waveform of the reference channel acquired in the preceding order in two adjacent acquisitions based on the acquisition times as a comparison waveform, wherein the adjacent acquisitions include at least the first acquisition and the second acquisition;

[0068] Waveform screening is performed based on the comparison waveform to obtain a waveform peak value to obtain the R peak, wherein the R peak is dynamically updated in sequence with the order of adjacent acquisitions.

[0069] It should be noted that, in this embodiment, Figure 5 As shown, a waveform diagram of three acquisitions is displayed, including the first acquisition, the second acquisition and the third acquisition, wherein the R peak is determined based on the maximum amplitude waveform of adjacent acquisitions, specifically, the average waveform of the maximum amplitude waveform of the reference channel of the preceding acquisition in the two adjacent acquisitions is extracted based on the acquisition number as the comparison waveform, wherein the adjacent acquisitions include at least the first acquisition and the second acquisition, and for this embodiment, since the acquisition number is three, the adjacent acquisitions include the first acquisition and the second acquisition, and the second acquisition and the third acquisition, waveform screening is performed based on the comparison waveform to obtain the waveform peak value to obtain the R peak, wherein the R peak is dynamically updated in sequence with the order of adjacent acquisitions, accordingly, the first acquisition and the second acquisition are the first adjacent acquisitions, and the corresponding R peak is the coordinate point ②, and the second acquisition and the third acquisition are the second adjacent acquisitions, and the corresponding R peak is the coordinate point ③, accordingly, the preceding acquisition of the first adjacent acquisition is the first acquisition, and the preceding acquisition of the second adjacent acquisition is the second acquisition.

[0070] Further, in one embodiment of the invention, the step of using the R peak as a reference peak of the current waveform for time-shift synchronization specifically includes:

[0071] The waveform translation reference peak of the order of the number of acquisitions is determined based on the order of adjacent acquisitions, wherein:

[0072] Extract the R peak corresponding to the first adjacent acquisition of the first acquisition and the second acquisition as the reference peak of the maximum amplitude waveform of the second acquisition for alignment and translation, and fill the incomplete data with zeros to complete synchronization;

[0073] The R peak corresponding to the second adjacent acquisition of the second acquisition and the third acquisition is extracted as the reference peak of the maximum amplitude waveform of the third acquisition for alignment and translation, and the incomplete data is filled with zeros to complete synchronization.

[0074] It should be noted that, in the present embodiment, the synchronization is specifically performed based on time for data synchronization, and the timing synchronization based on time needs to determine the reference peak and fill the incomplete data with zeros. Specifically, the R peak corresponding to the first adjacent acquisition between the first acquisition and the second acquisition is extracted as the reference peak of the maximum amplitude waveform of the second acquisition for alignment and translation, and the incomplete data is filled with zeros to complete the synchronization, that is, during the first translation, the alignment and translation are performed based on the coordinate point ② as the reference peak; the R peak corresponding to the second adjacent acquisition between the second acquisition and the third acquisition is extracted as the reference peak of the maximum amplitude waveform of the third acquisition for alignment and translation, and the incomplete data is filled with zeros to complete the synchronization, that is, during the second translation, the alignment and translation are performed based on the coordinate point ③ as the reference peak.

[0075] Furthermore, in one embodiment of the invention, after the time-shift synchronization, the waveforms of all the reference channels in each collected magnetocardiographic data are deleted to obtain synchronized target channel data, specifically including:

[0076] The total channel data is obtained based on the number of acquisitions and the number of magnetocardiograph signal channels;

[0077] Combining the acquisition times and the reference channel to obtain corresponding reference channel data;

[0078] The reference channel data is deleted from the total channel data to obtain the synchronized target channel data.

[0079] It should be noted that, in this embodiment, for the embodiment described in the aforementioned embodiment, the number of acquisitions is 3 times, and the number of magnetocardiograph signal channels is 14. Therefore, the total channel data is 42-channel data, and since the serial number "13-14" is an additional reference channel, the reference channel data is 6-channel data. The reference channel data is deleted from the total channel data to obtain the synchronized target channel data, that is, "42-6=36" to obtain 36-channel data consistent with the target data volume as the target channel data.

[0080] The embodiment of the present application also provides a magnetocardiograph data rapid synchronization system, which can implement the magnetocardiograph data rapid synchronization method described in the present application. However, the implementation device of the magnetocardiograph data rapid synchronization method described in the present application includes but is not limited to the structure of the magnetocardiograph data rapid synchronization system listed in the present embodiment.
