Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.
Fig. 1 shows a flow chart of a method of presenting a brain function connection map according to an embodiment of the present invention.
First, in operation S101, medical data, such as near infrared data, which can characterize a brain function state of a subject, may be acquired by a brain function detecting device, such as a near infrared spectrum detecting device, and brain function connection strength between respective locations on a brain region is calculated based on the acquired medical data. However, it should be understood that the medical data is not limited to near infrared data obtained by a near infrared spectrum detection device, and may be acquired by any other suitable technique and device, such as electroencephalogram data, MRI images, fMRI images, PET images, etc. Wherein, when the medical data is near infrared data, each position is a channel position, and when the medical data is electroencephalogram data, each position can be an electroencephalogram electrode position, and the like.
Then, in operation S102, a brain function connection map may be generated and displayed in the display interface based on the brain function connection strengths between the locations calculated in operation S101, wherein the brain function connection map may include, for example, brain region identifiers of the respective brain regions and image blocks corresponding to the brain function connection strengths between the locations. In some embodiments, the locations may correspond to, for example, channel locations in an SD layout from which near infrared spectroscopy is performed, or the like. The number of brain regions may be determined according to the specific requirements of the brain function detection, for example, 2 brain regions, 4 brain regions, 6 brain regions, etc., which is not limited in the present invention.
Taking the near infrared spectrum detection technology as an example, the brain function connection strength between the channels can directly or indirectly reflect the brain function state of the examinee, for example, for a newborn examinee, the brain function connection strength between different brain regions can reflect the phenomena of central node development retardation, low coordination capacity between the brain regions, low information transmission and integration efficiency and the like of an infant in the development process due to hypoxia and ischemia and the like, for example, the brain function connection strength between different brain regions can reflect the strength of the communication capacity between the brain regions and the like, so that the brain function connection strength information between the brain regions and the positions can be quickly and accurately acquired, and the brain function connection strength information has important significance for measuring the brain function state of the examinee, evaluating the brain injury condition, recovering condition or positioning the associated brain regions and/or position information and the like.
Taking the near infrared spectrum detection technology as an example, during detection, a plurality of pairs of probes are arranged on the head of a detected person, each pair of probes (including a transmitting probe and a receiving probe) are arranged to form a channel, and the brain function connection strength between each pair of channels can be represented by image blocks, that is, the brain function connection atlas may include hundreds of thousands of image blocks. In the method for presenting a brain function connection map according to the embodiment of the present invention, the inventor creatively arranges the positions according to the brain regions to which the positions belong, so that the image blocks are correspondingly arranged in the corresponding blocks arranged at intervals according to the brain regions to which the positions associated with the image blocks belong.
In some embodiments, the background of the display interface has a color, which may be a plurality 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, so that the user can obtain information, such as brain function connection strength between each brain region, each brain interval, and each position on each brain region, from the brain function connection map, which is not specifically limited by the present disclosure.
According to the brain function connection map displayed in the manner, the image blocks associated with the positions in the specific brain areas are arranged in the brain function connection map in an aggregation mode according to the areas, and due to the interval among the brain areas, a user can quickly and accurately locate information of one or a group of brain function connection strengths between the specific brain areas and/or the specific positions in the specific brain areas and other brain areas and/or other brain areas which the user wants to view. In other embodiments, when the user finds an abnormal image block in the brain function connection map, the arrangement of the brain region and the image block may also enable the user to quickly and accurately obtain the brain region and the position information corresponding to the concerned image block. In some embodiments, especially under the condition that there are many brain function locations and the data dimension included in the brain function connection map is large, the method for presenting a brain function connection map according to the embodiments of the present invention may provide a user with a convenient and accurate bidirectional index for viewing a specific (one or one group of) image block according to the associated brain region and location information, or viewing the corresponding brain region and location according to the concerned image block, thereby improving the efficiency and accuracy of subsequent brain function state evaluation and the like.
Figure 2 illustrates a schematic diagram of an exemplary brain function connection map based on near infrared data, in accordance with an embodiment of the present invention. The method for presenting a brain function connection map according to an embodiment of the present invention will be further described with reference to fig. 2.
As shown in fig. 2, in the brain function connection map 200 calculated based on the near-infrared data of the brain of the subject, which includes 6 brain regions, in some embodiments, the brain regions may be arranged in a preset order, for example, sequentially: in fig. 2, the brain area identifier on the left side represents one brain area associated with each image block in the brain function connection map 200, and the brain area identifier on the lower portion of fig. 2 represents another of the two brain areas associated with each image block, and all the brain areas are arranged in the order of the right forehead, the right temporal lobe, the left temporal lobe, and the left forehead, and correspondingly, the brain area identifiers on the lower portion of each brain area are arranged in the same order, so that 6 × 6 — 36 blocks in fig. 2 may be arranged in a preset order, and only as an example, the blocks corresponding to each pair of brain areas may be numbered in the order from top to bottom and from left to right: panel B1 corresponds to right anterior forehead-right forehead, panel B2 corresponds to right anterior forehead-right temporal lobe, panel B3 corresponds to right anterior forehead-right top lobe … …, and panel B36 corresponds to left forehead-left forehead. Thus, the positions may be arranged according to the brain regions to which they belong, for example, the two brain regions associated with the image block I201 in the figure are the right anterior forehead-the right top lobe, and thus, they are arranged in the block B3 in fig. 2.
As shown in fig. 2, the background of the display interface presented by the brain function connection atlas 200 is white, and each image block is an image block with a color (wherein the color of the image block is not shown), wherein the color of the image block corresponds to the brain function connection intensity value.
As shown in the legend on the right part of fig. 2, the color of each image block corresponds to the brain function connection intensity value between the positions associated with the color of each image block, which may be a real brain function connection intensity value, or a normalized intensity value for convenience of representation.
Since the respective patches are arranged at intervals as described above, a significant region aggregation effect is exhibited between the respective patches with the background white as a boundary. In other embodiments, the tiles may be arranged at equal intervals, as shown in fig. 2, the tiles B1 through B36 are arranged at equal intervals in a preset order, so that the tiles may be completely aligned according to their associated positions, thereby enabling the user to perform bidirectional search of the tiles and the corresponding positions and brain areas more quickly and accurately.
In some embodiments, the brain function connection atlas may further include a location identifier, such as the number of channels when near infrared data measurement is performed as shown in fig. 2, which may be used as the location identifier, such as the image block I201 in fig. 2, and its associated location may be the number of channel x and channel y, where x and y are two channels. It should be noted that when the image blocks in the brain function connection map 200 are dense and cannot display the position identifiers one by one, at least part of the position identifiers which are not required to be displayed temporarily may be hidden in a default state, so that the display interface only displays necessary information and keeps concise and clear.
In some embodiments, in order to enable the user to view the information in the brain function connection atlas 200 more clearly, various interaction operations may also be performed, for example, a first interaction may be performed on one or more image patches, and in response to the first interaction of the user on the brain function connection atlas, the respective image patch to which the first interaction is applied by the user may be hover enlarged. Particularly, in the case that the image blocks in the brain function connection map 200 are dense, when a user tries to view a specific image block in detail, for example, a first interaction may be applied to the image block I201 by a mouse click, a double click, a menu bar, or a right-click menu option, and the image block may be enlarged in a floating manner based on its original position so as to facilitate the user's viewing.
In some other embodiments, in addition to the hover zoom-in of each image patch to which the user applies the first interaction, the location identifier and/or the value of the brain functional connection strength corresponding to each image patch may be displayed independently or additionally. For example, for the image block I201, the numerical value (0.41) of the functional connection strength may be displayed on the enlarged image block, and/or the position identifiers x and y corresponding to the image block I201 may also be displayed on the enlarged image block or other suitable positions, for example only, the format of the position identifier display may be (x, y), x-y, or x: y, and the invention is not limited thereto. In other embodiments, when the numerical value of the functional connection strength is displayed, a numerical value consistent with the corresponding color in the legend may be displayed, and when the numerical value is a normalized value, the numerical value before normalization stored in the system may also be presented to the user at this time for reference when the doctor user performs diagnosis.
In other embodiments, on the basis of the above two operations, independently or additionally, the position identifiers of the respective image blocks to which the user applies the first interaction may also be displayed on the corresponding sides of the brain function connection atlas. 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 area identifier is not displayed.
In other embodiments, the image blocks of the first interaction applied by the user may be multiple, for example, the image blocks of all other positions associated with a specific position may be image blocks corresponding to a row or a column of image blocks in the brain function connection atlas 200, in which case, the position identifiers and/or the values of the brain function connection strengths corresponding to the respective image blocks may be displayed on or around the respective image blocks enlarged in suspension, or information of the image blocks focused by the respective users may be displayed in a list at a suitable position in the display interface, etc., which are not listed herein.
According to the embodiment of the invention, through the first interaction, the user can be helped to conveniently master the brain function connection strength between the specific position concerned by the user and other one or more positions, and more accurate analysis and diagnosis can be made on the basis of the brain function connection strength.
In some embodiments, the user may also have a second interaction with brain region identification in brain function connection map 200. In response to a second interaction of the user with the functional connectivity graph, for example, image patches associated with respective locations in a brain region corresponding to a brain region identification to which the second interaction was applied by the user may be hover enlarged.
By way of example only, when the user has implemented a second interaction with the right forehead brain area identification on the left side of the brain function connection map 200 via a mouse click, double click, menu bar, or right-click menu option, etc., then all image blocks associated with the various locations associated with the right forehead, i.e., 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), right forehead-left forehead (block B6), will be hover enlarged. In other embodiments, for example, when the user performs the second interaction not only on a certain brain region identifier on the left side of the brain function connection map 200, such as the right forehead, but also on one or more brain region identifiers on the lower side, such as the right temporal lobe and the right parietal lobe, then only the respective image blocks in the two blocks of the simultaneous right forehead-right temporal lobe (block B2) and right forehead-right parietal lobe (block B3) will be enlarged in suspension.
In some embodiments, while the image blocks associated with the positions in the brain region corresponding to the brain region identifier applied by the user for the second interaction are enlarged in a floating manner, the image blocks in the brain region corresponding to the brain region identifier applied by the user for the second interaction may be switched to a matrix composed of numerical values of the functional connection strength corresponding to the image blocks, so that the user can intuitively know specific numerical values of the functional connection strength of the brain between the positions in the concerned brain region, and in other embodiments, the numerical matrix may be further subjected to operations such as holding, and the like, so as to be used for subsequent calculation, processing, and the like.
According to the embodiment of the invention, through the second interaction, the brain function connection relation and the specific function connection strength between different brain areas can be visually checked by the user, so that favorable support can be provided for auxiliary analysis and accurate diagnosis of the characteristics of the brain function condition related to the brain function connection strength across the brain areas.
Fig. 3 is a schematic diagram illustrating a brain function connection map displayed in association with an SD layout according to an embodiment of the present invention. As shown in fig. 3, in the case where the brain function connection map 200 displayed in the first area a1 of the display interface is generated based on near-infrared data, the SD arrangement map 300 may also be displayed in the second area a2 of the display interface, so that the user can view the SD arrangement map 300 against the generated brain function connection map 200.
In general, a near infrared spectrum detection apparatus has a head cap, wherein the head cap may have a plurality of probes for transmitting and/or receiving near infrared signals thereon, or may be provided with mounting positions for the respective probes, and when performing measurement, each of the plurality of probes may be specifically configured as a transmitting probe (S) or a receiving probe (D) according to an SD arrangement pattern to be used for 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 vice versa, one receiving probe corresponds to a plurality of transmitting probes, and the pair relationship thereof may be specifically set in the SD arrangement pattern according to a brain region or the like to be detected. After the transmitting/receiving states of the probes on the headgear of the near infrared spectrum detection apparatus are set according to the SD arrangement diagram, near infrared data in the brain regions of the examinee can be acquired, and the brain function connection map 200 can be further generated based on the acquired near infrared data. By way of example only, one specific algorithm for generating a brain function connection map 200 based on near infrared data is as follows.
First, the time series of near-infrared data for each channel can be consideredIs equal, the Pearson correlation coefficient r of the time series of arbitrary channel pairs (channel i and channel j) is calculated by the following formula (1) ij And r is ij As a quantified value of the brain functional connection strength between channel i and channel j:
wherein n represents the length of the time series, k represents the kth point on the time series, X i (k) And X j (k) Time series X respectively representing channels i i And time series X of channel j j The sampled value at the k-th point,
and
respectively represent X i And X j Mean over the entire time series.
The quantified value of the brain function connection strength between each channel pair can be obtained through the formula (1). As can be seen from the brain function connection map 200, the matrix formed by the respective image blocks is a matrix symmetrical along the diagonal.
In the mode of viewing the brain function connection map 200 in comparison with the SD arrangement map 300, the user may implement a third interaction on one or more image blocks in the brain function connection map 200 by clicking with a mouse, double clicking, menu bar or right-click menu option, etc., and in response to the third interaction on the brain function connection map by the user, highlight channel information corresponding to the one or more image blocks on the SD arrangement map 300 to which the user applies the third interaction. In some embodiments, for example, when a third interaction is applied to the image block I301 in the brain function connection map 200, correspondingly, two channels associated with the image block I301, the channel identifiers of the channel 3 located on the left forehead and the channel 49 located on the right temporal lobe and line segments thereof may be thickened and/or highlighted on the SD layout 300, or a highlighting operation such as a blinking highlighting operation, which is not particularly limited herein. In some embodiments, the user may also apply the third interaction to the plurality of image blocks at the same time, and when the channels associated with the plurality of image blocks are highlighted on the SD layout 300, for example, a pair of channels corresponding to a specific image block may be identified and highlighted in the same color as the image block on the SD layout 300, and the invention is not limited in specific manner.
Since the SD layout 300 can visually check the positions of the channels relative to the brain region, the relative relationships with other nearby channels, and the like, the brain function connection map 200 is checked against the SD layout 300 according to the embodiment of the present invention, and the response to the third interaction of the user is beneficial for the user to check the exact and detailed strength values, positions, brain regions, and other comprehensive information of the brain function connection concerned by the user simultaneously and comparatively.
In some embodiments, the presentation method further comprises: in response to a fourth interaction of the user with the brain function connection atlas, the tiles and/or image blocks in the tiles are highlighted. In some embodiments, the fourth interaction may be a selection operation such as a click operation, a mouse-over operation, and the like performed by the user on the block and/or an image block in the block, and based on the fourth interaction performed by the user, the corresponding content may be highlighted, for example, the unselected content may be weakened by containing other unselected contents in ash, blurring, and the like, or the selected content may be highlighted by floating, enlarging, adding a border line, and the like, or the weakening manner of the unselected content may be combined with the highlighting manner of the selected content, as long as the selected content can be highlighted, so that the user can quickly obtain information of the selected content, which is not specifically limited by the present disclosure. In one embodiment, a user may connect to a block on the atlas by clicking on brain functions, for example, clicking on a block corresponding to the top right leaf and the top left leaf shown in fig. 2, and in response to a click operation on the block by the user, all other non-selected blocks may be grayed out, so that the block can be highlighted, so that the block can be focused on, and the whole information of the block and the information of each image block located in the block can be quickly obtained.
