  In addition to the finding ID, the editing processing unit 42 adds a doctor ID for identifying the interpretation doctor who has input the finding sentence to each finding data. The doctor ID is input by the interpretation doctor at the time of user authentication when the report creation terminal 13 is activated. Finding data can be searched by finding ID or doctor ID.

  The edit processing unit 42 creates a finding sentence corresponding to the selection input state of each panel 51, 52, term selection button 53, etc., based on the finding sentence creation definition stored in the storage device 32. The definition for creating the observation sentence has the hierarchical structure of the data in the order of the observation item, observation item, and words for each observation item, with the organ item as the apex, the position in the observation sentence of each observation item section, and the observation item Specifies the order of words in a clause. For the definition of finding sentence, for example, the observation sentence is classified into the main part and the predicate for each observation item, and the main part and predicate are classified into the main part and the modifying part that modifies the main part, and the observation sentence is composed. The words to be sorted are assigned to each part. In the definition for creating a finding sentence, the main part of the predicate is further classified by the use position depending on whether it is in the middle or the end of the finding sentence, and the use form depending on whether it is a positive or negative form. In FIG. 3, the usage format is negative only when “None” is selected with the term selection button 53 in the observation items “degree of swelling” and “degree of atrophy”. Everything else is positive.

  Taking the observation item “swelling” as an example, the modification part of the main part includes the input words of the subordinate item “swelling part”, “whole liver”, “right lobe”, “left lobe”, main The main part of the part has the observation position “swelling”, and the predicate ’s main part has the input positions of “mild”, “moderate”, and “high” as subordinate items “swelling degree”. In the middle, the usage format is positive, “Minor,” the usage position is the end, the usage format is positive, “Mild.”, Etc. “None” is registered at the end, the usage format is negative.

  When any one of the term selection buttons 53 is selected, the edit processing unit 42 first follows the organ item and the hierarchy of the finding items corresponding to the selection state of the panels 51 and 52 for the creation of the finding sentence creation. Then, the phrase of the observation item (hereinafter referred to as an active observation item) corresponding to the selected term selection button 53 is read from the finding sentence creation definition.

  Subsequently, the edit processing unit 42 determines the main body part of the predicate of the active observation item. The edit processing unit 42 examines the usage position and usage format of the section related to the active observation item. The edit processing unit 42 looks at whether or not an observation item at the same hierarchical level (sibling relationship) as the active observation item is active in the order in which the observation sentence creation definition is registered. If there is another active observation item after the active observation item whose use position and usage type are to be determined, the use position is “middle”, otherwise “end”.

  When the usage format of the word corresponding to the selected term selection button 53 is “No”, that is, when “swelling degree-none” or “atrophy degree-none” is selected in the example of FIG. The processing unit 42 determines that the usage format of “swelling” and “atrophy” is “No”. Everything else is affirmed. The edit processing unit 42 reads the words of each part read from the finding sentence creation definition as described above in the order of the main part modifier, the body part, the predicate modifier, and the body part (the definition of the finding sentence creation definition). Link up according to the order of registration (registration)) and create a finding sentence.

  Taking the selection state of each of the panels 51 and 52 and the term selection button 53 in FIG. 3 as an example, a description sentence creation process of the editing processing unit 42 will be described. Since “liver” and “liver form” are selected as the panels 51 and 52, the edit processing unit 42 follows the “liver” in the definition for creating a finding sentence and the “liver form” below it. Then, the main part of the main part of the active observation item (in this case, all from “rim” to “substantially”), the modification part of the main part and the predicate, and the like are read from the definition for the finding sentence creation.

  In this case, since all the observation items are active, the use position is “on the way” from the observation items “edge” to “substantial uniformity”. In addition, since “swelling degree—none” and “atrophy degree—none” are not selected, the usage types of the observation items are all “affirmation”. Therefore, the edit processing unit 42 selectively reads out words / phrases whose use position is in the middle and the use format is affirmative as the main part of the predicate other than the observation item “substantial density” from the definition for creating the observation sentence. When the various phrases read out in this way are connected according to a predetermined order, the finding sentence described in FIG. 3 and paragraph [0057] is obtained.

  As another example, when only “edge-blunt” is selected, the finding sentence is “edge blunt.” In addition, when only “Expansion degree-None” is selected, the observation texts are “No enlargement”, “Atrophy degree-Moderate”, and “Atrophy site-Whole liver” only. , The observation sentence is "Atrophy of the entire liver is moderate." If only “substantially-non-uniform” is selected, the observation text is “substantially non-uniform”. When there is only one active observation item, the observation sentence is a single sentence, and when there are a plurality of active observation items, the observation sentence is a multiple sentence including sections relating to each observation item.

  FIG. 4 shows a term selection input area 48 and a diagnosis name input area 49 when the tab of the small classification panel 52 is switched to “mass lesion”. Hereinafter, the term selection input area 48 and the diagnosis name input area 49 of “mass lesion” are particularly referred to as a lesion description template 65.

  Similar to the example shown in FIG. 3, the lesion description template 65 includes a term selection button 53 such as “irregular” or “low echo” for each of a plurality of observation items such as “shape” and “internal echo”. Has been. The term selection button 53 is not arranged for the observation items “part”, “size”, and “infiltration destination”, and an input box 66 for receiving keyboard input is provided instead. The input box 66 is also provided at the right end of the observation item “number”. In the input box 66, words indicating the location of the mass lesion such as “right lobe”, “left lobe”, “S1” to “S8”, sizes of “15”, “10”, “3”, etc. A numerical value representing the location can be input by keyboard operation. The input box 66 at the right end of the observation item “number” is used when there are many lesions appearing on the examination image 17 and the site, size, and state of each lesion are exactly the same. In the definition for creating a finding sentence of the lesion description template 65, a part to be input by the keyboard is registered as a blank.

  In FIG. 4, as the term selection button 53, as shown by diagonal lines, “shape-unshaped”, “internal echo-low echo”, “echo pattern-mixing”, “uniformity-nonuniform”, “rear echo— “Invariant”, “blood flow signal—slight”, and “calcification—none” are selected. In addition, “part-S2” and “size-30 mm × 20 mm” are input to the input box 66 using the keyboard. The method for selecting the term selection button 53 and the procedure for creating the finding sentence are the same as those in the example of FIG.

  Above the lesion description template 65, a progress information button 67, a pull-down menu 68, and a lesion addition button 69 are provided. The pull-down menu 68 is used to select and specify a new addition or copy of the lesion description template 65. When an inverted triangle mark beside the pull-down menu 68 is clicked, new and copy options are displayed in a pull-down manner. The lesion addition button 69 is operated when a new addition or copy instruction signal selected and designated by the pull-down menu 68 is input.

  In addition, the lesion description template 65 is provided with an add button 70 that can add only “part” and “size” of the observation items. Note that the observation items that can be partially added are not limited to “part” and “size” in the above example, but may be “shape” or the like. If it is possible to add some observation items that are supposed to require a plurality of inputs in the case of multiple lesions, it is possible to contribute to smoother and faster entry of the lesion findings.

  The diagnosis name input area 49 of the lesion description template 65 includes, in addition to the reliability input pull-down menu 55 and the input box 56 in the example shown in FIG. Pull-down menus 71 and 72 for inputting the stage such as type II are prepared. The lesion description template 65 is not limited to the “mass lesion”, but may be applied to a lesion description template of “hemorrhagic lesion” such as intracerebral hemorrhage or subarachnoid hemorrhage, for example. There is also a lesion description template 65 that does not have a pull-down menu 72 for inputting a disease stage (see lesion ID “00002” in FIG. 11).

  If there are many lesions appearing in the examination image 17 and one of them is solid, and the other is a cystic mass lesion, etc., it is recognized that the state of each lesion is completely different. New is selected and the lesion addition button 69 is clicked. When new is designated in the pull-down menu 68 and the lesion addition button 69 is clicked, a new addition instruction signal is transmitted to the console control unit 40 as shown in FIG. The console control unit 40 receives the new addition instruction signal and reads the drawing data of the lesion description template 65 from the drawing data 75 of the storage device 32. This drawing data represents the lesion description template 65 in a plain state in which the term selection button 53 is not selected and nothing is input in the input boxes 56 and 66.

  The console control unit 40 switches the display on the display 37b from the state shown in FIGS. 4 to 6 based on the read drawing data 75. In FIG. 6, the console control unit 40 displays the tab “# 2” (new addition tab 80) of the newly added lesion description template 65 after the “mass lesion” tab of the small classification panel 52.

  On the other hand, if it is recognized that the appearance of many lesions appearing in the examination image 17 is partially different, the image interpretation doctor selects a copy of the pull-down menu 68 and clicks the add lesion button 69. When a copy is designated in the pull-down menu 68 and the lesion addition button 69 is clicked, a copy instruction signal is transmitted to the console control unit 40 as shown in FIG. The console control unit 40 reads the drawing data 75 representing the plain lesion description template 65 from the storage device 32 in the same manner as when the new addition instruction signal is received. In addition, the console control unit 40 reads temporary storage data 76 indicating the selection state of the term selection button 53 on the tab “mass lesion” that is the copy source from the memory 31.

  The console control unit 40 reproduces the selection input state of the term selection button 53 to the plain lesion description template 65 using the temporary storage data 76, and switches the display on the display 37b from the state shown in FIG. 4 to FIG. The tab “# 2” (copy addition tab 81) shown in FIG. 7 is different from the plain new addition tab 80 in which the term selection button 53 is not selected, and the term selection button 53 in the “mass lesion” tab. The selected state is maintained as it is. FIG. 7 shows the same selection state as the lesion description template 65 shown in FIG.

  The name “# 2” of each of the additional tabs 80 and 81 means the second tab of the original “mass lesion”. Further, when the lesion description template 65 is added / copied, the additional tabs 80 and 81 of “# 3”, “# 4”,... Are sequentially added after the “mass lesion” tab. After the term selection button 53 on the new addition tab 80 is selected and input, it can be copied or the copy addition tab 81 can be further copied.

  When the new addition tab 80 or the copy addition tab 81 is added, a delete button 73 is generated beside the lesion addition button 69 of the lesion description template 65. The delete button 73 is clicked when the new addition tab 80 or the copy addition tab 81 is deleted.

  If the lesion is a multiple lesion but the site and size are different and the other aspects are substantially the same, the image interpretation doctor clicks the add button 70. When the add button 70 is clicked, the console control unit 40 reads the drawing data 75 in which the observation items “part” and “size” are added to the lower part of the original item from the storage device 32, and displays the drawing data 75 on the lower side of FIG. As shown, it is displayed on the display 37b. The added observation items “part” and “size” (additional item 82) are provided with a delete button 83 in the same manner as the additional tabs 80 and 81 of the above embodiment, and the observation items “part” and “size” are provided. "Can be freely added or deleted.

  In the finding sentence created using the lesion description template 65, a lesion ID for identifying each lesion is associated and stored. When each of the additional tabs 80 and 81 and the additional item 82 is added, the finding sentence input area 46 is automatically added, and the finding sentence input by them includes the tab of the original “mass lesion” and the original observation. Different lesion IDs are newly issued for the items “part” and “size”.

  In FIG. 9 showing the data structure of the report 18, the report 18 includes patient information such as a patient ID and a patient name, examination information such as an examination ID, an examination date, an examination purpose, and finding information as data. The finding information includes a finding ID, finding data, a doctor ID, a selection input state, and the like. The finding information based on the lesion description template 65 has a lesion ID in addition to the above. In addition to this, the image 18 stores the image ID of the inspection image (key image) referred to when the report 18 is created, information on the order, and the like.

  As shown in FIG. 10, the lesion ID is assigned by the storage processing unit 61 of the DB server 14. The storage processing unit 61 creates the report 18 when the lesion ID is not included in the finding information by the lesion description template 65 among the data of the report 18 transmitted together with the storage request from the DB access unit 41 of the report creation terminal 13, that is, the report 18 is newly created. When the additional tabs 80 and 81 and the additional item 82 are added, a lesion ID is newly issued and added to the finding information.

  On the other hand, when the follow-up of the lesion is used for the examination and the previous report 18 of the patient is used as a copy, since the lesion ID has already been issued and added to the finding information, the storage processing unit 61 sets the lesion ID as the lesion ID. Take over without change.

  The storage processing unit 61 extracts data such as the report ID, patient ID, examination date, selection input state of the lesion description template 65, diagnosis name, progress, stage, and lesion ID from the data of the report 18 and stores them in the lesion DB 22. It is registered in the lesion table 24 shown in FIG. The lesion table 24 includes items such as lesion ID, selection input state, diagnosis name, progress, stage, report ID, and examination date. These items are collected for each patient ID, that is, for each identical patient. According to this lesion table 24, it is possible to trace the history and progress of lesions that have occurred so far for a certain patient.

  For example, the lesion with the lesion ID “00001” of the patient with the patient ID “01234” is first discovered in the examination “10/7/30 (July 30, 2010)” and is reported in the report 18 with the report ID “01524”. Findings are written. The selection input state at that time is “part-S2”, “size-30 mm × 20 mm”, “shape-unshaped”, “internal echo-low echo”, etc., as in the example shown in FIG. . The diagnosis name is “malignant tumor” and the stage is “type I”. Since this is the first lesion found, nothing is registered in the progress item.

  The lesion with the lesion ID “00001” is also seen in the subsequent three follow-up examinations, and information corresponding to this is registered following the first line. The size of the selection input state is “34 mm, 25 mm”, “22 mm, 15 mm”, and “22 mm, 15 mm” in the follow-up observation three times, and the progress has been worsened, improved, and unchanged. The stage is consistent with “Type I”. On the other hand, the lesion with the lesion ID “00002” has been cured and disappeared by surgery or drug administration in the second follow-up.

  The report ID and examination date from the first examination to the second follow-up of the lesion with the lesion ID “00002” and the lesion with the lesion ID “00003” are the same. That is, these lesions are found in the same examination, and are described in the same report 18 by adding each of the additional tabs 80 and 81 or the additional item 82.

  When a lesion ID is newly issued, the storage processing unit 61 newly creates a row for registering the lesion ID in the row of the patient in the lesion table 24, and fills in the selection input state and other items. When the existing lesion ID is inherited, the storage processing unit 61 adds one line to the row of the lesion ID of the patient in the lesion table 24 and adds other items to the row. For this reason, when a new lesion is found or for each follow-up examination, information on the lesion is added to the row of the patient or the row of the lesion ID. If the lesion is healed by surgery or drug administration, additional information about the lesion stops there.

  When an instruction to copy and use the previous report 18 is received from the console control unit 40 through the input device 38 using the patient ID or examination ID as a search key, the DB access unit 41 searches the search processing unit 62 of the DB server 14 to search. Send a request. The search processing unit 62 searches and extracts the data of the instructed report 18 from the report DB 21, and delivers the extracted data to the DB access unit 41. Based on the data delivered to the DB access unit 41 and the drawing data 75, the console control unit 40 causes the display 37b to display a report editing screen 44 that reproduces the previous selection input state of the report 18. If there is an instruction to create a new report 18 instead of using a copy of the past report 18, the search / extraction of the data of the report 18 is not performed, and the plain report editing screen 44 is displayed.

  In addition, using information such as the patient ID of the order received by the order acquisition unit 43 and the examination purpose as a search key, whether the patient has been previously examined under the same conditions or not is searched from the past orders. Thus, it may be determined whether the order is the first inspection or a reexamination such as follow-up observation. If it is determined to be the first inspection, a report editing screen 44 for creating a new report 18 is displayed. If it is determined to be a re-inspection, the previous report 18 is automatically searched to edit the report that reproduces the selected input state. A screen 44 is displayed.

  The progress information button 67 can be selected when the follow-up of the lesion is intended for examination and the previous report 18 of the patient is used as a copy. When the progress information button 67 is clicked, the console control unit 40 transmits to the DB access unit 41 a search key for acquiring the progress information of the lesion whose description is described in the lesion description template 65. Specifically, the search key is a lesion ID of the lesion attached to the data of the report 18 used by copying, and there may be one or a plurality of cases.

  In FIG. 10, the DB access unit 41 transmits a search request for progress information using the received search key to the search processing unit 62 of the DB server 14. The search processing unit 62 searches and extracts a lesion ID that matches the lesion ID of the search key from the lesion table 24. The search processing unit 62 creates a progress information list 90 shown in FIG. 12 based on the information of each item stored in the extracted lesion ID row, and transmits this to the DB access unit 41 as a search result.

  In FIG. 12, the progress information list 90 extracts items such as patient ID, diagnosis name, progress, and stage from the lesion table 24 from the lesion ID line designated by the search key, and further selects the data portion in the selected input state. , Size, volume, etc., are extracted and listed. (A) shows the case where the lesion ID “00001” in the lesion table 24 shown in FIG. 11 is designated as the search key, and (B) shows the case where the lesion IDs “00002” and “00003” are designated. Since the lesion IDs “00002” and “00003” are found in the same examination and described in the same report 18 as described above, they are transmitted together as a search key. Although not shown, the progress information list 90 is attached with a report ID and an image ID of a key image that can be traced from the report ID.

  The DB access unit 41 passes the progress information list 90 received from the search processing unit 62 to the console control unit 40. The console control unit 40 displays the progress information list 90 on the display 37b as it is or by processing the progress information list 90 and changing the layout information to an easily viewable layout.

  FIG. 13 shows a display example when lesion IDs “00002” and “00003” are designated as search keys and the progress information list 90 shown in FIG. 12B is transmitted. In this example, the thumbnail of the key image, the numerical value of the volume, the line graph, the progress, and the transition of the diagnosis name for each examination date are displayed. The thumbnail of the key image is searched and extracted from the image DB 20 using the image ID of the progress information list 90 as a search key. The volume line graph is obtained by plotting each numerical value for each examination date normalized by the maximum value of the volume with an appropriate vertical scale. In this example, the diagnosis names and line graphs of the two lesions with lesion IDs “00002” and “00003” are displayed on the same skin, but the diagnosis names and line graphs of each lesion may be displayed separately. These displays may be switchable.

  Hereinafter, the operation of the above configuration will be described with reference to the flowcharts shown in FIGS. The requesting doctor issues an order using the medical department terminal 11. The report creation terminal 13 receives the order issued from the clinical department terminal 11 via the order reception terminal of the examination department 12.

  The interpretation doctor accesses the report creation terminal 13 to confirm the order and starts creating the report 18. When the report editing screen 44 is displayed on the display 37b, an image display screen is displayed on the display 37a in conjunction therewith. The radiologist interprets the observation text for each organ in the observation text input area 46 of the report editing screen 44 while observing the examination image 17 on the image display screen.

  The input of the finding sentence is performed by selecting the term selection button 53. In FIG. 14, when the term selection button 53 is selected (Yes in step (hereinafter abbreviated as S) 10), the console control unit 40 sends the editing processing unit 42 the panels 51 and 52, the term selection button 53, etc. The selection input state is notified. The selection input state is sent to the memory 31 through the console control unit 40, and the temporary storage data 76 is stored in the memory 31 (S11).

  Next, the search for the finding sentence creation definition based on the selection input state of each panel 51, 52, the term selection button 53, etc. is executed by the editing processing unit 42, and the phrase of each observation item is read from the finding sentence creation definition. (S12).

  Subsequently, the editing processing unit 42 determines the section usage position and usage format for each observation item (S12). Specifically, if the observation item at the same hierarchical level as the observation item to be judged and the observation item after the observation item to be judged are active, the use position is judged as “middle”; Is determined. When the usage format of the input phrase corresponding to the selected term selection button 53 is “No”, the usage format is determined to be “No”. All other cases are determined as “affirmed”. The phrase of the main part of the predicate based on the determination result of the use position and the use format is read from the finding sentence creation definition.

  Then, the various words that have been read out are linked in the order in which the finding sentence creation definition is arranged, and the finding sentence is created (S13). The created finding sentence is transferred from the editing processing section 42 to the console control section 40 and displayed in the finding sentence input area 46 under the control of the console control section 40 (S14). In this manner, the image interpretation doctor inputs the finding sentence while selecting the term selection button 53 or inputting a phrase in the input box 56. These series of processes are repeatedly executed every time the term selection button 53 is additionally selected.

  When the interpretation doctor finishes inputting the finding sentence, the interpretation doctor selects the end button 58 (Yes in S15). When the end button 58 is selected, a data storage request for the report 18 is transmitted from the DB access unit 41 to the DB server 14. When a storage request is received from the report creation terminal 13, in the DB server 14, the storage processing unit 61 executes storage processing for data of the report 18. The data of the report 18 is stored in the report DB 21. This completes the process of creating a single report 18.

  In FIG. 15, when the report 18 data is stored, when the report 18 is newly created, or when each of the additional tabs 80 and 81 and the additional item 82 is added (yes in S20), the storage processing unit 61 causes the lesion ID to be stored. Is newly issued and added to the finding information of the report 18. In addition, a newly issued lesion ID line is newly added to the lesion table 24, and each item is extracted from the data of the report 18 and registered (S21).

  On the other hand, when the previous report 18 is copied and used (no in S20), the existing lesion ID is inherited and the data of the report 18 is stored. In addition, one line is added to the line of the lesion ID of the patient in the lesion table 24 and each item is added (S22).

  When the creation of the report 18 is completed, a report of completion of creation is transmitted from the report creation terminal 13 to the medical department terminal 11 of the requesting doctor. The requesting doctor accesses the report DB 21 through the medical department terminal 11 and reads the report 18 based on the address of the report 18 included in the creation completion notification. A report display screen and an image display screen for displaying the examination image 17 related to the report 18 are output to the display 37 of the medical department terminal 11. The requesting doctor browses these screens and confirms the contents of the report 18.

  In FIG. 16, when the previous report 18 is copied and the progress information button 67 is selected on the screen of the lesion description template 65 (Yes in S30), a search key is sent from the console control unit 40 to the DB access unit 41. Is transmitted from the DB access unit 41 to the search processing unit 62 of the DB server 14 (S31).

  Then, the search processing unit 62 searches and extracts the lesion ID that matches the lesion ID of the search key from the lesion table 24 (S32), creates a progress information list 90 based on the extracted information, and accesses the DB as a search result. It is transmitted to the unit 41 (S33).

  The progress information list 90 received by the DB access unit 41 is delivered to the console control unit 40. Then, the console control unit 40 displays a thumbnail of the key image or a line graph on the display 37b based on the progress information list 90 (S34).

  As described above, according to the present invention, the selection input state of the lesion description template 65 is stored and managed in units of lesions, and the progress information of the lesion is retrieved and displayed in response to the retrieval request. As compared with the conventional technique for extracting words and phrases, the accuracy of extracting lesion progress information can be improved. It is not necessary to perform a special analysis such as morphological analysis, and the selection input state and diagnosis name of the lesion description template 65 are reflected in the progress information as they are, so that the validity and credibility of the progress information is also ensured.

  Since a lesion ID that uniquely identifies each lesion is used as a search key, the extracted progress information is always that of the specified lesion ID, and a search error is unlikely to occur. Therefore, there is no room for doubt about the validity and credibility of the progress information, and the interpreting doctor can use the progress information as reference material when creating the report 18 with peace of mind.

  In the above-described embodiment, the progress information of the same lesion of the same patient is searched and extracted using the lesion ID as a search key, and the search result is displayed. However, data in the selection input state may be used as the search key. In this way, it is possible to search and extract and display the progress information of a plurality of lesions of other patients having the same selection input state, that is, the symptom, in addition to the patient undergoing the examination.

  In this case, a pull-down menu is provided next to the progress information button 67 for selecting whether to search for the progress information of the same lesion of the same patient or to search for the progress information of the similar lesion of another patient. Then, after the term selection button 53 or the input box 66 of the lesion description template 65 is selected and input, the search for the progress information of similar lesions of other patients is designated from the pull-down menu and the progress information button 67 is clicked. The search processing unit 62 of the DB server 14 is caused to search the lesion table 24 using the data in the selected input state as a search key. In this case, the lesion of the patient is excluded from the search target. If the search key is a numerical value such as volume or size, the search may be performed with a width in the numerical value range. In addition, for example, a narrowing search may be performed such as limiting to the inspection date of the most recent month, or limiting the progress to only cases that have improved.

  The search processing unit 62 collects the search results as a progress information list and transmits it to the DB access unit 41 as in the above embodiment. The console control unit 40 causes the display 37b to display progress information of similar lesions of other patients based on the progress information list.

  For example, consider a case where an intracerebral hemorrhage of “part-putamen”, “volume-3.2 cc”, and “concentration—equal absorption” developed in the first examination. The interpreting physician enters “putamen” and “3.2” in the input box 66 of the site and volume of the lesion description template 65 (not shown) for the bleeding lesion, and selects a term selection button for the observation item “concentration” After selecting 53 “Iso-absorption”, the search for the progress information of similar lesions of other patients is designated and the progress information button 67 is clicked.

  Then, the DB access unit 41 transmits a search request using “part-putamen”, “volume—3.0 cc to 3.5 cc”, and “concentration—equal absorption” as search keys to the search processing unit 62. The search processing unit 62 extracts lesion data that matches the search key from the lesions in the lesion table 24, creates a history information list indicating the history of the extracted lesions from the onset, and creates a DB access unit 41.

In this case, a search key input box is provided on the display screen of the medical department terminal 11, and the lesion progress information corresponding to the lesion ID and the selection input state of the lesion description template 65 input in the input box is the same as in the above embodiment. The DB server 14 searches and extracts the search result and transmits the search result to the medical department terminal 11. Alternatively, the progress information list may be automatically transmitted together with the report 18 creation completion notification. By providing the progress information of the lesion to the viewing of the requesting doctor, it becomes easy to make informed consent with the patient at the time of the examination. It can also be used to make treatment plans.

  In the above embodiment, when the copy addition tab 81 is added, only the selection state of the term selection button 53 is copied, but the input content of the input box 66 may be copied.

  In the above embodiment, the keyboard and the mouse are described as examples of the input device. However, the selection of the term selection button 53 may be received by voice using a microphone as the input device.

  In the above-described embodiment, the examination performed by the examination department 12 is described as an example, but the examination type is not limited to these, and may be a PET (Positron Emission Tomography) examination, an endoscopic examination, or the like. In short, the present invention is applicable as long as a lesion description text is input using a lesion description template.

  In the above-described embodiment, an example in which there is one report creation terminal has been described. However, a plurality of report creation terminals may be used. Moreover, although the aspect which stores drawing data in the storage device of a report preparation terminal was illustrated, the storage location of drawing data is not restricted to the above, You may store in DB server. In this case, the DB access unit of the report creation terminal accesses the DB server to transmit a drawing data search request and receive the search result. Furthermore, although the lesion DB is constructed in the DB server and the medical information providing apparatus of the present invention is configured by the report creation terminal and the DB server, the report creation terminal (console control unit) and the DB server (storage processing unit, A dedicated device that integrates the functions of the search processing unit and provides lesion progress information may be provided.

  In the case of a client server type information system comprising a client (report creation terminal) and a server (DB server) as in the above embodiment, a dedicated program is used as a client program for report editing. Alternatively, a general-purpose browser corresponding to a WWW (World Wide Web) protocol such as HTTP (Hyper Text Transfer Protocol) may be used.

  When a dedicated program is used, the report edit screen is generated based on screen data defined by the dedicated program. When a general-purpose browser is used, for example, the report edit screen data is stored in the Web server, and the client accesses the Web server and stores the report edit screen data processed into the Web page format. to download. The client browser interprets the source code of the received Web page and generates a report editing screen. The Web server may be shared by the DB server or may be a server different from the DB server. When a general-purpose browser is used, the CPU of the Web server configures an editing processing unit, a console control unit, and the like in cooperation with the CPU of the client or independently.

  The data storage device in which the DB is constructed may be other than the DB server, and for example, a storage device connected via a network such as NAS (Network Attached Storage) or SAN (Storage Area Network) may be used. Thus, the physical configuration of the computer system can be changed as appropriate.

  In the above embodiment, the LAN is described as an example of the network. However, when the clinical department and the examination department are distributed at a plurality of bases, a combination of the LAN and the WAN (Wide Area Network) is used as the network. May be used.

  Note that, as shown in the above embodiment, the present invention naturally extends to the form of a program and further to a storage medium for storing the program.
