Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical document creation support device and a program, and more particularly, to a medical document creation support device and a program that contribute to improving the efficiency of creating a medical document.
[0002]
[Prior art]
Various documents are created at the medical site. With the spread of information processing equipment in recent years, these documents have been digitized and stored as digital data (electronic documents). Creation of digital data involves various input operations. Conventionally, input using an input device such as a keyboard has been general. However, with the development of voice recognition technology, a voice input method is becoming widespread, which contributes to an efficient input operation.
[0003]
Here, in Japanese input, so-called “kana-kanji conversion” is generally performed by software processing. In this case, the conversion is usually performed with reference to the dictionary file. The dictionary file describes correspondences between readings and converted words, grammatical rules, and the like. As such a dictionary file, in addition to a dictionary that records commonly used words, specialized dictionaries corresponding to terms specific to specialized fields etc. are prepared as necessary, and even special terms and phrases can be smoothly. Can be converted.
[0004]
Although specialized dictionaries have also existed in the medical field described above, the medical field is diversified and has many special terms and idioms, so that the amount of information in the dictionary file is extremely large. On the other hand, there is one aspect that the technical terms used are limited to some extent depending on the examination subject, the body part to be examined, or the type of medical device used.
[0005]
Therefore, when a single dictionary file covering all medical terms is used, a conversion candidate must be selected from an enormous amount of information, which may increase the processing time. Alternatively, the number of conversion candidates to be presented may increase, and the user must distinguish the corresponding word from the candidates. In the case of the voice input method, the erroneous recognition rate also increases. Therefore, using a single medical dictionary may hinder efficient conversion processing.
[0006]
On the other hand, even if the dictionary file is subdivided, even if the target body part, the medical device used, the medical examination subject, the doctor in charge, the attribute of the target patient, the target disease, the situation, the treatment content, the administered drug, etc. Since the optimum dictionary file differs depending on the various conditions, the optimum dictionary file must be selected each time a document is created (updated). Therefore, complicated work is involved, and the work efficiency is reduced.

More specifically, the control unit 210 executes the “DB control program”, newly creates a record of the original image file in the original image DB 260, and stores the original image information constituting the captured image in the record. Also, the “imaging part information” and “apparatus information” added by the imaging apparatus 100 are recorded in the original image file as header information.
[0045]
The person in charge operates the input device 23 and inputs other header information, that is, “patient information”, “person in charge information”, “related information”, and the like. The control unit 210 additionally records the input information in the header information of the image file (step S105), and ends the processing.
[0046]
(Diagnosis image creation processing)
Next, "diagnosis image creation processing" by the image processing apparatus 300 will be described with reference to the flowchart shown in FIG. Here, an image used for diagnosis is created by performing predetermined image processing on the original image information stored in the original image DB 260 of the control terminal 200. For example, when the original image is composed of three-dimensional image data, the original image is converted into two-dimensional image information to create an image for diagnosis (for example, an image that displays an affected part so that it can be clearly identified).
[0047]
First, the processing is started by the control unit 310 executing the “image processing program” stored in the program storage unit 350 in response to the operation of the input device 33 by the person in charge. By the operation of the image processing program, a screen for selecting an image to be processed is displayed on the output device 34 (display device in this case). Here, a list of original image files stored in the original image DB 260 of the control terminal 200 is displayed by cooperation of the communication programs of the image processing apparatus 300 and the control terminal 200.
[0048]
The person in charge designates an original image file to be processed from the displayed list (step S201). When the target image file is selected, the communication control unit 320 acquires the specified original image file from the original image DB 260 of the control terminal 200 (Step S202).
[0049]
When acquiring the original image file from the original image DB 260 of the control terminal 200, the control unit 310 executes the “DB control program” stored in the program storage unit 350 and stores the processed image file (processed image file). Records to be processed are processed image DB 360 ₁ Create a new one. The control unit 310 stores “header information” included in the acquired original image file in the created record (step S203). Further, the control unit 310 holds the original image information included in the acquired original image file in the work area.
[0050]
Processed image DB 360 ₁ When the header information is stored in the control unit 310, the control unit 310 displays on the output device 34 a screen for selecting the image processing to be performed (hereinafter, referred to as a “processing menu screen”). On the processing menu screen, various “image processing modes” (for example, “cerebral blood flow analysis” and “heart analysis”) that can be executed by the image processing apparatus 300 are displayed in a selectable manner. The person in charge operates the input device 33 and specifies the image processing mode to be executed. The control unit 310 records information indicating the selected image processing mode in the “processing history information” column of the record created in step S203 (step S204).
[0051]
The control unit 310 performs image processing corresponding to the designated image processing mode on the original image information held in the work area (step S205).
[0052]
Here, depending on the case or the like, image processing may be performed while transitioning between a plurality of image processing modes. When there is such a change in the image processing mode (step S206: Yes), the control unit 310 records the executed image processing mode transition history in the “processing history information” as header information of the processed image file. (Step S207).
[0053]
When the image processing is completed (Step S208: Yes), the control unit 310 stores the processed image information forming the image subjected to the image processing in the record created in Step S204 (Step S209), and ends the processing. .
[0054]
(Interpretation report creation processing)
Next, “interpretation report creation processing” by the image processing apparatus 300 will be described with reference to the flowchart shown in FIG. Here, the “interpretation report” is a medical document created in the image diagnosis, in which a diagnostic image and findings are recorded.
[0055]
This processing is started by the control unit 310 executing the “document creation program” stored in the program storage unit 350 in response to the operation of the input device 33 by the person in charge.
[0056]
Based on the operation of the document creation program, the control unit 310 displays a “template selection screen” as shown in FIG. Here, the document template DB 360 ₂ Is displayed in a selectable manner. The person in charge operates the input device 33 to select a desired template (here, “interpretation report”).
[0057]
The control unit 310 executes the DB control program and executes the document template DB 360 ₂ , The selected template is obtained (step S301). The acquired template is held in the work area and displayed on the output device 34 as shown in FIG.
[0058]
As shown in the figure, an “image insertion frame” is arranged in the template of the interpretation report, and a target “processed image” is inserted here. The person in charge operates the input device 33 to specify a processing image to be inserted. Here, the processing image DB 360 is operated by a predetermined operation. ₁ Is displayed, and a target processed image file is selected from the list.
[0059]
When the target processed image file is selected, the control unit 310 executes the DB control program to execute the processed image DB 360 ₁ And obtains the specified processed image file (step S302) and stores it in the work area.
[0060]
Next, the control unit 310 activates a “dictionary selection program” stored in the program storage unit 350 and selects a dictionary file to be used when inputting a finding in the radiological report (“dictionary selection process”) (step S400). Execute This "dictionary selection process" will be described with reference to the flowchart shown in FIG.
[0061]
The control unit 310 acquires “header information” recorded in the processed image file acquired in step S302 (step S401).
[0062]
The control unit 310 estimates the body part of the target patient by referring to the “relative coordinate information” in the acquired header information (step S402). Here, a rough body part (for example, “head”) is estimated.
[0063]
Next, the control unit 310 refers to the “device information” and specifies the type of the imaging device used for imaging (step S403).
[0064]
Next, the control section 310 refers to the “processing history information”, and specifies a diagnosis target part based on the recorded image processing mode and the body part estimated in step S402 (step S404). Here, the details of the target part are specified. For example, when the “head” is estimated in step S402 and the “image processing mode” is “cerebral blood flow analysis”, it is specified that the diagnosis target site is “brain”.
[0065]
The control unit 310 includes a dictionary DB 360 ₃ To specify a dictionary file corresponding to the “imaging device” specified in step S403 and the “target part” specified in step S404 (step S405). The control unit 310 adds flag information (flag ON) to the specified dictionary file (step S406), and returns to the "interpretation report creation process" (FIG. 11). The flag information added here indicates that it is a dictionary file used by the voice recognition program (or IM program) in the input processing described later.
[0066]
When a dictionary is selected in the "dictionary selection process", the acquired header information and the information indicating the specified target part are inserted into a predetermined position of the template, and the processed image is inserted into the image insertion frame (step S303). . FIG. 15 shows an example of the “interpretation report” in which each information is inserted.
[0067]
Next, the control unit 310 executes an “input process” (step S500) for inputting the finding of the person in charge in the interpretation report into which each information is inserted. This “input processing” will be described with reference to the flowchart shown in FIG. In the present embodiment, it is assumed that a voice input device such as a microphone is used as the input device 33, and that “findings” are voice input based on the utterance of the person in charge.
[0068]
(Input processing)
As shown in FIG. 14, the "interpretation report" is provided with an area for inputting the finding of the person in charge (hereinafter referred to as "finding input area"). The person in charge operates the input device 33 such as a pointing device, for example, and selects this finding input area. This processing is started when the control unit 310 activates the IM program stored in the program storage unit 350 in response to the selection of the finding input area.
[0069]
When the voice input of the finding is ready, the person in charge operates the input device 33 such as a pointing device and selects the “input start” button arranged near the finding input area. When detecting the selection of the “input start” button (step S501: Yes), the control unit 310 activates the “voice recognition program” stored in the program storage unit 350 (step S502).
[0070]
The person in charge, for example, presses (long-presses) a predetermined key of the keyboard (input device 33), and speaks toward the input device 33 such as a microphone while pressing the key, so that the voice signal is generated. The data is input to the control unit 310 via the input control unit 330. Here, the control unit 310 permits voice input only while the key is being pressed, thereby preventing unnecessary blanks and mixing of voice signals other than speech voice. The control unit 310 sequentially recognizes the input voice signals by the operation of the voice recognition program and the IM program being executed (step S503). Here, the control unit 310 executes the dictionary DB 360 as needed. ₃ And performs speech recognition while referring to the dictionary file whose flag is ON. More specifically, by extracting feature amounts of input speech and matching the extracted feature amounts with “acoustic model”, “dictionary”, and “language model”, a word corresponding to each phoneme is obtained. To be converted. Here, the findings to be entered (input) in the radiological report include many words related to the diagnosis target site and the diagnostic device (imaging device). Since it is selected, it is converted with high recognition accuracy.
[0071]
When the voice input of the finding ends, the person in charge selects the “input end” button arranged near the finding input area. In response (Step S504: Yes), the control unit 310 stops the voice recognition operation by the voice recognition program (Step S505), ends the input processing, and returns to the “interpretation report creation processing” (FIG. 11). Return.
[0072]
The file of the interpretation report to which the findings have been input is output to the output device 34 such as a display or a printer, or stored in a predetermined storage location (database or the like) (step S304), and the process ends.
[0073]
As described above, according to the medical document creating system 1 according to the embodiment of the present invention, a necessary and sufficient dictionary is obtained from a specialized dictionary file subdivided based on the header information of the image file taken in the radiology report. Since voice recognition is performed by selecting a file, voice recognition can be performed with high recognition accuracy and at high speed. In addition, since the dictionary file is automatically specified, a complicated operation such as a dictionary selection by the user is not required.
[0074]
In the above embodiment, the specialized dictionary files are classified by “body part” and “medical device”, but the classification items and the number of classifications are not limited to those described above, and are arbitrary. For example, classifications such as “disease name”, “drug name”, and “diagnosis subject” may be added.
[0075]
In the above-described embodiment, an example has been described in which findings are input by voice, but the input method to which the present invention can be applied is not limited to this. For example, the present invention can be applied to a case where a finding is input using a keyboard or the like. In this case, the dictionary file specified at the time of the “kana-kanji conversion” by the IM program may be used. Even in this case, since the conversion is performed using only the necessary and sufficient dictionary file, the number of conversion candidates can be reduced and the input efficiency can be improved.
[0076]
The information used to specify the dictionary file is not limited to the header information of the image file, and information input by a person in charge or the like may be used to specify the dictionary file. Further, the update of the dictionary file (so-called “dictionary registration”) may be performed at any time. In this case, if dictionary registration is performed for the specified dictionary file, dictionary registration can be performed efficiently.
[0077]
In the above embodiment, the case where the dictionary file is specified has been described as an example. However, the configuration may be such that other language information is specified. For example, in the case of a template in which findings are input by selecting and combining prepared fixed phrases, a set of these fixed phrases is classified and prepared in the same manner as the dictionary file, and the same as in the above embodiment. A set of fixed phrases may be specified by a technique.
[0078]
In the above embodiment, the case where the “interpretation report” is created has been described as an example. However, the present invention can also be applied to the creation of an arbitrary medical document (for example, “medical record” or “medical certificate”). it can.
[0079]
In the above-described embodiment, an example in which an interpretation report is created on the image processing apparatus 300 has been described. However, a medical document is created on another apparatus (terminal) using an image processed by the image processing apparatus 300. May be. In this case, for example, it can be created on a terminal used by a doctor or the like in a consultation room. The terminal (physician terminal) used here may be a simple one in which the configuration related to image processing is omitted from the image processing device 300. Then, through the above “imaging processing” and “diagnosis image creation processing”, the diagnostic image is processed by the processing image DB 360 of the image processing apparatus 300. ₁ Is stored in The doctor's terminal executes the same processing as the above “interpretation report creation processing” to display (1) the template, (2) obtain the processed image from the image processing apparatus 300, and (3) obtain the processed image. A dictionary is selected based on the header information of the processed image, and (4) a finding is input using the selected dictionary. According to such a configuration, even when a doctor in charge in the examination room or the like fills out the findings of the interpretation report, medical documents can be efficiently created by applying the present invention.
[0080]
Further, in the above-described embodiment, an example has been described in which each device in the medical facility H is connected by the communication network 10. However, for example, a WAN (Wide Area Network: wide area information communication network) connects a plurality of medical facilities. The present invention may be applied in an environment connected by.
[0081]
The control terminal 200 and the image processing device 300 according to the above-described embodiment can be configured not only by a dedicated device but also by a general-purpose computer device such as a personal computer. In this case, the control terminal 200 and the image processing apparatus 300 can be configured by installing a part or all of the program for realizing each of the above processes in a general-purpose computer device and executing the program under control of an OS or the like. . In this case, the program distribution form is arbitrary. For example, it can be stored and distributed on a recording medium such as a CD-ROM, or can be distributed via a communication medium (such as the Internet) by being superimposed on a carrier wave.
