[0015] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the common meanings understood by persons with ordinary skills in the field to which the present invention belongs. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.

[0017] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0018] Figure 1 A flow chart showing a method for presenting a brain functional connection map according to an embodiment of the present invention.

[0019] First, in operation S101, medical data such as near-infrared data that can characterize the brain function state of the subject can be obtained through brain function detection equipment such as near-infrared spectroscopy detection equipment, and the brain function connection strength between various positions on the brain region can be calculated based on the obtained medical data. However, it should be noted that the above medical data is not limited to near-infrared data obtained by near-infrared spectroscopy detection equipment, and can also be obtained by any other applicable technology and equipment, such as EEG data, MRI images, fMRI images, PET images, etc. Among them, when the medical data is near-infrared data, each position is a channel position, and when it is EEG data, each position can be a brain electrode position, and so on.

[0020] Then, in operation S102, a brain function connection map can be generated and displayed in a display interface based on the brain function connection strength between each position calculated in operation S101, wherein the brain function connection map can include, for example, brain region identifiers of each brain region, and image blocks corresponding to the brain function connection strength between each position. In some embodiments, the above-mentioned positions can correspond to, for example, channel positions in the SD arrangement diagram based on which near-infrared spectroscopy detection is performed. In addition, the number of brain regions can be determined according to the specific needs of the brain function test performed, for example, 2 brain regions, 4 brain regions, 6 brain regions, etc., and the present invention is not limited to this.

[0021] Taking near-infrared spectroscopy detection technology as an example, the strength of brain functional connections between channels can directly or indirectly reflect the brain functional state of the subject. For example, for newborn subjects, it can reflect the delayed development of central nodes, low coordination ability between brain areas, low efficiency of information transmission and integration caused by hypoxia and ischemia in the development of the child. For example, the strength of brain functional connections between different brain regions can reflect the strength of communication ability between brain areas. Therefore, quickly and accurately obtaining brain functional connection strength information between brain regions and positions is of great significance for measuring the brain functional state of the subject, evaluating its brain injury and recovery status, or locating related brain regions and / or position information.

[0022] Taking near-infrared spectroscopy detection technology as an example, during detection, multiple pairs of probes are arranged on the head of the subject, and each pair of probes (including a transmitting probe and a receiving probe) is arranged to form a channel. The brain function connection strength between each pair of channels can be represented by an image block, that is, the brain function connection map may contain hundreds or thousands of image blocks. In the method for presenting a brain function connection map according to an embodiment of the present invention, the inventor creatively arranges the various positions according to the brain regions to which they belong, so that the above-mentioned image blocks are arranged in corresponding blocks arranged at intervals according to the brain regions to which the positions to which they are associated belong.

[0023] In some embodiments, the background of the display interface has a color, which can be a variety of colors, such as white, gray, black, etc. As long as the color of the background of the display interface can be distinguished from the color of the image block, the user can obtain information such as the strength of brain function connections between various brain regions, between various brain regions, and between various positions on each brain region from the brain function connection map. The present disclosure does not make specific limitations on this.

[0024] According to the brain function connection map displayed in the above manner, the image blocks associated with the positions in the specific brain area will be presented in the brain function connection map as clustered and arranged by blocks, and because there are intervals between each brain area, the user can quickly and accurately locate the information of one or a group of brain function connection strengths between the specific brain area and / or the specific position in the specific brain area and other brain areas and / or specific positions in other brain areas that he wants to view. In other embodiments, when the user finds an abnormal image block in the brain function connection map, the arrangement of the above brain area and image blocks can also enable the user to quickly and accurately obtain the brain area and position information corresponding to the image block of interest. In some embodiments, especially when there are many brain function positions and the data dimension contained in the brain function connection map is large, the method for presenting the brain function connection map according to the embodiment of the present invention can provide users with a convenient and accurate two-way index for viewing a specific (one or a group) image block according to the associated brain area and position information, or viewing the corresponding brain area and position according to the image block of interest, thereby improving the efficiency and accuracy of subsequent brain function state assessment.

[0025] Figure 2 A schematic diagram of an exemplary brain functional connection map based on near infrared data according to an embodiment of the present invention is shown. Figure 2 The method for presenting the brain functional connection map according to an embodiment of the present invention is further described.

[0026] like Figure 2 As shown in FIG. 2 , in the brain functional connection map 200 calculated based on the near-infrared data of the subject's brain, 6 brain regions are included. In some embodiments, the brain regions can be arranged in a preset order, for example, in the order of right frontal lobe, right temporal lobe, right parietal lobe, left parietal lobe, left temporal lobe and left frontal lobe. Figure 2 In the figure, the brain region logo on the left represents a brain region associated with each image block in the brain functional connection map 200, and Figure 2 The brain region labels at the bottom represent the other of the two brain regions associated with each image block, and are arranged in the order of right frontal lobe, right temporal lobe, right parietal lobe, left parietal lobe, left temporal lobe, and left frontal lobe. Correspondingly, the brain region labels of the brain regions at the bottom are arranged in the same order. Figure 2 There are 6*6=36 blocks in total, which can be arranged in a preset order. As an example, the blocks corresponding to each pair of brain regions can be numbered from top to bottom and from left to right: block B1 corresponds to right frontal-right frontal, block B2 corresponds to right frontal-right temporal lobe, block B3 corresponds to right frontal-right parietal lobe... block B36 corresponds to left frontal-left frontal. In this way, each position can be arranged according to the brain region to which it belongs. For example, the two brain regions associated with image block I201 in the figure are right frontal-right parietal lobe, so it is arranged in Figure 2 In block B3.

[0027] like Figure 2 As shown, the background of the display interface presented by the brain function connection map 200 is white, and each image block is a colored image block (the color of the image block is not shown), wherein the color of the image block corresponds to the brain function connection strength value.

[0028] like Figure 2 As shown in the legend on the right, the color of each image block corresponds to the brain function connection strength value between its associated positions, which can be the real brain function connection strength value, or for the sake of convenience of representation, it can be a normalized strength value. In this case, for example, the brain function connection strength value between all positions can be calculated first, and each brain function connection strength value can be normalized relative to the maximum value, and then the color corresponding to each normalized value can be set and used to set the image block color.

[0029] As mentioned above, the blocks are arranged at intervals, so the blocks present a significant regional aggregation effect with the background white as the dividing line. In some other embodiments, the blocks can be arranged at equal intervals, such as Figure 2 As shown, the blocks B1 to B36 are arranged in a preset order and at equal intervals, so that the image blocks can be completely aligned according to their associated positions, so that users can perform bidirectional retrieval between image blocks and corresponding positions and brain regions more quickly and accurately.

[0030] In some embodiments, the brain functional connectivity map may also include location markers, such as Figure 2 The channel numbers for near-infrared data measurements shown in can be used as position identifiers, for example, Figure 2 In the image block I201, its associated position may be channel x and channel y, where x and y are the labels of the two channels. It is worth noting that when the image blocks in the brain functional connection map 200 are dense and it is impossible to display each position mark one by one, at least some of the position marks that do not need to be displayed temporarily can be hidden in the default state, so that the display interface only displays necessary information and remains concise and clear.

[0031] In some embodiments, in order to enable the user to more clearly view the information in the brain function connection map 200, various interactive operations can also be performed, for example, a first interaction can be performed on one or more image blocks, and in response to the user's first interaction on the brain function connection map, each image block to which the user applies the first interaction can be suspended and enlarged. In particular, when the image blocks in the brain function connection map 200 are relatively dense, when the user attempts to view a specific image block in detail, for example, the first interaction can be applied to the image block I201 by clicking the mouse, double-clicking, menu bar or right-click menu options, and the image block can be suspended and enlarged based on its original position to facilitate user viewing.

[0032] In some other embodiments, in addition to suspending and enlarging each image block to which the user applies the first interaction, independently or additionally, the position identifiers corresponding to each image block and / or the numerical values ​​of the brain functional connection strength can also be displayed. For example, for image block I201, the numerical value (0.41) of its functional connection strength can be displayed on the enlarged image block, and / or, the position identifiers x and y corresponding to image block I201 can also be displayed on the enlarged image block or other appropriate positions. As an example only, the format of the position identifier display can be (x, y), xy, or x: y, etc., and the present invention does not limit this. In some other embodiments, when displaying the numerical value of the functional connection strength, a numerical value consistent with the corresponding color in the legend can be displayed. When the numerical value is a normalized value, the numerical value before normalization stored in the system can also be presented to the user for reference when the doctor user makes a diagnosis.

[0033] In other embodiments, based on the above two operations, independently or additionally, the position identifiers of each image block where the user applies the first interaction may also be displayed on the corresponding side of the brain function connection map. In some embodiments, the position identifiers x and y associated with the image block I201 may be respectively identified on the other two sides where the brain region identifier is not displayed.

[0034] In some other embodiments, the image blocks to which the user applies the first interaction may be multiple, for example, may be image blocks of all other positions associated with a specific position, or may be image blocks corresponding to a row or a column in the brain function connection map 200. In this case, the position identifiers corresponding to each image block and / or the numerical values ​​of the brain function connection strength may be displayed on or around each suspended and enlarged image block, or the information of each image block that the user is concerned about may be displayed in the form of a list at an appropriate position in the display interface, etc., which are not listed one by one here.

[0035] According to an embodiment of the present invention, through the first interaction, the user can easily grasp the strength of brain function connection between the specific location of interest and one or more other locations, and make more accurate analysis and diagnosis on this basis.

[0036] In some embodiments, the user may also perform a second interaction on the brain region identifier in the brain functional connection map 200. In response to the user's second interaction on the functional connection map, for example, an image block associated with each position in the brain region corresponding to the brain region identifier to which the user performs the second interaction may be suspended and enlarged.

[0037] As an example only, when the user implements the second interaction on the right frontal brain area identifier on the left side of the brain function connection map 200 by clicking, double-clicking, menu bar or right-click menu option, then all image blocks associated with the various positions associated with the right forehead, that is, right forehead-right forehead (block B1), right forehead-right temporal lobe (block B2), right forehead-right parietal lobe (block B3), right forehead-left parietal lobe (block B4), right forehead-left temporal lobe (block B5), and right forehead-left forehead (block B6) will be suspended and enlarged. In other embodiments, for example, when the user not only performs the second interaction on a brain region marker on the left side of the brain function connection map 200, such as the right forehead, but also performs the second interaction on one or more brain region markers on the lower side, such as the right temporal lobe and the right parietal lobe, then only each image block in the two blocks of right forehead-right temporal lobe (block B2) and right forehead-right parietal lobe (block B3) will be suspended and enlarged at the same time.

[0038] In some embodiments, while floating and magnifying the image blocks associated with each position in the brain area corresponding to the brain area identifier to which the user applies the second interaction, the image blocks in the brain area corresponding to the brain area identifier to which the user applies the second interaction can be switched to a matrix composed of numerical values ​​of functional connection strengths corresponding to the image blocks, so that the user can intuitively understand the specific numerical values ​​of the brain functional connection strengths between each position in the brain area of ​​concern. In other embodiments, the above-mentioned numerical matrix can also be maintained for subsequent calculations and processing.

[0039] According to an embodiment of the present invention, through the second interaction, the user can intuitively view the brain functional connection relationship and the specific functional connection strength between different brain regions, thereby providing favorable support for auxiliary analysis and accurate diagnosis of the characteristics of brain functional conditions associated with the brain functional connection strength across brain regions.

[0040] Figure 3 FIG. 1 is a schematic diagram showing the association display of a brain function connection map and a SD topography map according to an embodiment of the present invention. Figure 3As shown, when the brain function connection map 200 displayed in the first area A1 of the display interface is generated based on near-infrared data, it can also be displayed together with the SD arrangement diagram 300 in the second area A2 of the display interface, so that the user can compare the SD arrangement diagram 300 with the generated brain function connection map 200.

[0041] Typically, a near-infrared spectroscopy detection device has a head cap, wherein the head cap may have a plurality of probes for sending and / or receiving near-infrared signals, or mounting positions capable of assembling various probes. When performing measurements, each of the plurality of probes may be specifically configured as a transmitting probe (S) or a receiving probe (D) according to the SD layout diagram to be used for the current measurement, wherein each pair of probes arranged in pairs forms a channel, wherein one transmitting probe may correspond to a plurality of receiving probes, or conversely, one receiving probe corresponds to a plurality of transmitting probes, and the pairing relationship thereof may be specifically set in the SD layout diagram according to the brain region to be detected, etc. After setting the transmitting / receiving state of each probe on the head cap of the near-infrared spectroscopy detection device according to the SD layout diagram, the near-infrared data in each brain region of the subject may be collected, and a brain function connection map 200 may be further generated based on the collected near-infrared data. As an example only, a specific algorithm for generating a brain function connection map 200 based on near-infrared data is as follows.

[0042] First, we can assume that the length of the time series of the near-infrared data of each channel is equal, and calculate the Pearson correlation coefficient r of the time series of any channel pair (channel i and channel j) by the following formula (1): ij , and r ij As a quantitative value of the brain functional connection strength between channel i and channel j:

[0043]

[0044] Where n represents the length of the time series, k represents the kth point in the time series, and X i (k) and X j (k) represents the time series X of channel i respectively i and the time series X of channel j j The sample value at the kth point, and Respectively represent X i and X j The mean over the entire time series.

[0045] The quantitative value of the brain functional connection strength between each channel pair can be obtained by formula (1). It can be known from the brain functional connection map 200 that the matrix formed by each image block is a matrix symmetrical along the diagonal line.

[0046] In the mode of comparing and viewing the brain function connection map 200 and the SD layout map 300, the user can implement the third interaction on one or more image blocks in the brain function connection map 200 by clicking, double-clicking, menu bar or right-click menu options, etc., and in response to the user's third interaction on the brain function connection map, the channel information corresponding to the one or more image blocks to which the user applies the third interaction is highlighted on the SD layout map 300. In some embodiments, for example, when the third interaction is applied to the image block I301 in the brain function connection map 200, correspondingly, the channel identifiers and line segments of the two channels associated with the image block I301, channel 3 located in the left forehead and channel 49 located in the right temporal lobe, can be bolded and / or highlighted, or flashed and highlighted, etc., on the SD layout map 300, without specific limitation. In some embodiments, the user can also apply a third interaction to multiple image blocks at the same time. When channels associated with multiple image blocks are highlighted on the SD layout diagram 300, for example, a pair of channels corresponding to a specific image block can be marked and highlighted on the SD layout diagram 300 with the same color as the image block, etc. The present invention does not limit the specific method.

[0047] Since the position of each channel relative to the brain area and the relative relationship with other nearby channels can be viewed more intuitively in the SD layout diagram 300, by comparing the brain function connection map 200 with the SD layout diagram 300 according to an embodiment of the present invention and responding to the user's third interaction, it is beneficial for the user to simultaneously and comparatively view the exact and detailed intensity values, positions, brain areas and other comprehensive information of the brain function connections they are concerned about.

[0048] In some embodiments, the presentation method further includes: in response to the user's fourth interaction with the brain function connection map, highlighting the block and / or the image block in the block. In some embodiments, the fourth interaction can be a selection operation such as a click operation or a mouse hover operation on the block and / or the image block in the block. Based on the fourth interaction implemented by the user, the corresponding content can be highlighted. For example, the unselected content can be weakened by graying out or blurring other unselected content, or the selected content can be highlighted by suspended enlargement, adding border lines, etc., or the method of weakening the unselected content can be combined with the method of highlighting the selected content. As long as the selected content can be highlighted so that the user can quickly obtain information about the selected content, the present disclosure does not make specific limitations on this. In a specific embodiment, the user can click on a block on the brain function connection map, such as clicking Figure 2The blocks corresponding to the right parietal lobe and the left parietal lobe shown in the figure can, in response to the user's click operation on the block, all other unselected blocks can be grayed out, so that the block can be highlighted, so that the user can focus on the block and quickly obtain the overall information of the block and the information of each image block located in the block.

[0049] Figure 4 FIG. 2 is a schematic diagram showing a partial structure of a device for presenting a brain function connection map according to an embodiment of the present invention.

In addition, it may also store data obtained by a brain function detection device such as a near-infrared spectroscopy detection device for generating a brain function connection map that needs to be presented on a display interface, as well as data and indicators that users need to record and store based on various interactive instructions.
