[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] like Figure 1As shown, a method for reversely associating structured content based on free text of the present invention includes the following steps: S10, obtaining the free text selected by the user in a structured report, the structured report including more than two structured CDEs; S20, displaying the upper-level structured CDE associated with the free text selected by the user; S30, obtaining the upper-level structured CDE grammatical information according to the upper-level structured CDE and the preset grammar generation logic; S40, based on the preset grammar search logic, back-tracing the upper-level structured CDE grammatical information to obtain the positioning information of the control corresponding to the free text selected by the user in the upper-level structured CDE or the positioning information of the structured CDE to which the corresponding control belongs; S50, marking the specified position in the upper-level structured CDE according to the positioning information.

[0029] Preferably, the free text selected by the user in the structured report is obtained, for example, the user clicks on the corresponding content of a free text. The free text is a doctor's supplementary description of the imaging findings in the structured imaging report.

[0030] The present invention performs a back-tracing search on the grammatical information of the upper-level structured CDE based on a preset grammar search logic to obtain the location information of the control corresponding to the free text selected by the user in the upper-level structured CDE or the location information of the structured CDE to which the corresponding control belongs; and then identifies the designated position in the upper-level structured CDE according to the location information, so as to quickly find the relevant structured content corresponding to the free text, thereby effectively improving the search efficiency.

[0031] For example, when the reviewing doctor browses the patient's prostate report and clicks on the free text related to the prostate size in the "Overall Assessment" section of the prostate report, according to the selected free text (i.e., the free text related to the prostate size), Figure 2 As shown, the parent structured CDE (ie, the "overall assessment" structured CDE) associated with the free text is displayed.

[0032] In this embodiment, the preset syntax generation logic uses the lowest level control or structured CDE (common data element) in the structured report as the basic description element of the structured report; each structured CDE defines a syntax tree, and each node or leaf in the syntax tree is specifically a control. The same-level content under a tree node in the syntax tree is at the same level.

[0033] Preferably, the control type includes at least one of single selection, multiple selection, edit box, and phrases not displayed on the interface. Among them, the phrases not displayed on the interface can be understood as phrases that are logically a type of control, but are not displayed on the structured report interface, and can be used as intermediate values ​​for calculation, and can be used to calculate the separate code of each part of the lesion list. Because the part code is used more frequently in the lesion, it is more convenient to use an intermediate phrase to store this code.

[0034] In this embodiment, step S30 includes at least the following steps: S31. According to the displayed upper-level structured CDE, starting from the uppermost level, obtain the corresponding syntax of all structured CDEs and controls from top to bottom; S32. According to the preset grammar generation logic, starting from the lowest-level control or structured CDE in the structured report, perform grammar improvement in sequence between the same levels, and perform grammar improvement step by step from bottom to top between non-same levels to obtain the grammar information of the upper-level structured CDE.

[0035] The present invention generates grammatical information corresponding to structured content according to the grammar tree through preset grammar generation logic, from leaves to roots, which can be directly used as the basis for subsequent backtracking search without the need to associate the grammatical information with controls, thereby simplifying the implementation process of the search method.

[0036] In this embodiment, when performing grammar improvement, it is specifically improved according to different text languages, sequences and preset supplementary conjunctions, preset punctuation marks, preset paragraphs and preset script dynamic logic.

[0037] Preferably, the preset supplementary conjunctions include at least one of and, with, or, and; the preset punctuation includes at least one of a comma, a period, and a semicolon; the preset paragraphs include at least one of a carriage return and an indented blank line; the preset script dynamic logic is specifically: modifying and / or combining the existing tree structure grammar to form a new grammar. The generation of certain grammars (which may be a word, character, or sentence, etc.) requires the combination of multiple controls, such as the volume value of the lesion. After the user enters the length, width, and height of the lesion, the system internally calculates (i.e., combines the existing tree structure grammar) to generate the volume value to form a new grammar.

[0038] In this embodiment, step S40 is specifically as follows: based on the preset grammar search logic, backtracking search is performed on the upper-level structured CDE grammar information from top to bottom to determine whether the structured CDE or control corresponding to the free text selected by the user in the upper-level structured CDE is found; if the corresponding structured CDE is found, the search continues to the lower level until all structured CDEs are found or the corresponding control is found; if the corresponding control is found, the corresponding positioning information of the control is obtained.

[0039] It is understandable that each structured CDE has a syntax tree defined therein, where CDE is a branch and the lower level may include one or more CDEs and / or controls, so the search in step S40 needs to find all structured CDEs or leaves (i.e., controls).

[0040] The present invention performs a back-tracing search on the upper-level structured CDE grammatical information from top to bottom based on a preset grammar search logic, thereby enabling rapid positioning of relevant structured content corresponding to free text, assisting doctors in quickly modifying structured reports, thereby improving doctors' work efficiency, and avoiding erroneous modifications to structured reports caused by low accuracy of doctors' own searches, thereby ensuring the quality of structured reports.

[0041] In this embodiment, in step S50, marking the designated position in the upper-level structured CDE specifically includes: formatting and / or dynamically marking the designated position in the upper-level structured CDE.

[0042] Preferably, the format identifier includes at least one or more of: color identifier (for example, changing the color of the specified position), bold identifier, highlight identifier, graphic identifier (for example, identifying the specified position with a rectangular frame), and underline identifier; dynamic identifier includes flashing identifier and / or automatic jump to the specified position.

[0043] The present invention can highlight the structured content that needs to be modified by formatting and / or dynamically marking the designated positions in the upper-level structured CDE, prompting the doctor to make modifications at the designated positions, thereby further improving the doctor's work efficiency.

[0044] like Figure 3 As shown, the present invention also provides a system for reversely associating structured content based on free text, which includes: an instruction acquisition module 10, used to obtain the free text selected by the user in a structured report, and the structured report includes more than two structured CDEs; a display module 20, used to display the parent structured CDE associated with the free text selected by the user; a grammar information generation module 30, used to obtain the grammar information of the parent structured CDE according to the displayed parent structured CDE and the preset grammar generation logic; a backtracking search module 40, used to backtrack the grammar information of the parent structured CDE based on the preset grammar search logic, and obtain the positioning information of the control corresponding to the free text selected by the user in the parent structured CDE or the positioning information of the structured CDE to which the corresponding control belongs; an identification module 50, used to identify the specified position in the parent structured CDE according to the positioning information.

[0045] For ease of understanding, the following Figure 4, the method of reversely associating structured content based on free text described in the present invention is explained.

[0046] For example, when the reviewing doctor is browsing the patient's prostate report and clicks near the free text "2.2" in the structured report (such as where the arrow in the figure indicates), the parent structured CDE associated with the free text (i.e., the structured content of the "Overall Assessment" section shown in the figure) is automatically displayed based on the free text selected by the user.

[0047] According to the displayed upper structured CDE, starting from the uppermost level, the corresponding syntax of all structured CDEs and controls is obtained from top to bottom; according to the preset syntax generation logic, starting from the lowest level control or structured CDE in the structured report, the syntax is improved in sequence between the same level, and the syntax is improved from bottom to top between non-same levels, and the syntax information of the prostate "overall assessment" is obtained as follows:

[0048] Prostate diameter: 1.5cm×2.2cm×3.1cm (left and right×front and back×up and down)×0.52=5.32ml.

[0049] Volume summary syntax: 1.5cm×2.2cm×3.1cm(left and right×front and back×up and down)×0.52=5.32ml.

[0050] Left and right grammar: 1.5cm.

[0051] Control value: 1.5 (the control value is the value diagnosed by the doctor based on the patient's images).

[0052] Front and back grammar: 2.2cm.

[0053] Control value: 2.2.

[0054] Upper and lower syntax: 3.1cm.

[0055] Control value: 3.1.

[0056] Based on the preset grammar search logic, the syntax information of the upper-level structured CDE is backtracked and searched step by step from top to bottom (in this embodiment, first backtrack to the content of "overall evaluation", and then search the lower level, the lower level is the volume summary grammar, and then search the lower level, the lower level is the before and after grammar), to determine whether the structured CDE or control corresponding to the free text selected by the user in the upper-level structured CDE is found; if the corresponding structured CDE is found, continue to search the lower level until all structured CDEs are found or until the corresponding control is found; if the corresponding control is found (in this embodiment, the edit box control of "Control value: 2.2" is found), the corresponding positioning information of the control is obtained. It can be understood that the above-mentioned "backtracking search of the syntax information of the upper-level structured CDE from top to bottom" specifically refers to the overall order of backtracking search, and for the same level content, the search is performed in sequence.

[0057] The designated position in the upper-level structured CDE is marked according to the positioning information (marked with a rectangular frame in this embodiment) to prompt the doctor to make modifications at the designated position.

[0058] The embodiment of the present invention further provides a computer-readable storage medium, which may be a computer-readable storage medium included in the memory in the above embodiment; or a computer-readable storage medium that exists independently and is not installed in a device. The computer-readable storage medium stores at least one instruction, which is loaded and executed by a processor to implement Figure 1 The method for reversely associating structured content based on free text is shown. The computer-readable storage medium may be a read-only memory, a disk or an optical disk, etc.
