  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a configuration diagram showing a schematic overall configuration of a system constructed in a medical institution according to an embodiment of the present invention. This system S is composed of three main systems: a medical information management system H, a radiation department information management system R, and an ordering system OS operated across both systems.

  First is the medical information management system H (HIS). This HIS is a system used not only in each department's examination department, but also in the appointment department, accounting department, pharmacy department, and the like. In the HIS according to the embodiment of the present invention, for example, an information terminal H1 used by a doctor who examines a patient and a database H2 that stores patient reservation information and diagnostic information, a medical practice implementation registration status using a medical device, and the like. It consists of. In FIG. 1, two information terminals H1 and H1 and one database H2 are shown as elements constituting the HIS, but the elements constituting the HIS are not limited to these devices and numbers.

The radiation department information management system R (RIS) is a system used particularly in the radiology department. The RIS is composed of an information terminal R1 that is mainly used by an engineer or the like for implementation registration work of a radiology order, and a database R2 that registers the radiology order. Further, although not included in the RIS, a medical image diagnostic apparatus R3 that captures medical images managed by the RIS is also connected to a communication network N described later. The medical image diagnostic apparatus R3 is an apparatus that acquires internal information of a patient (subject) and generates a medical image. Examples thereof include an X-ray diagnostic apparatus and an X-ray CT (computed tomography) apparatus. be able to. Here, since the X-ray diagnostic apparatus and the X-ray CT apparatus are already well-known devices, description of the internal configuration, imaging method, and the like will be omitted.

  In FIG. 1, one information terminal R1, one database R2, and two medical image diagnostic apparatuses R3 and R3 are shown. However, the types of constituent elements are not particularly limited, and the number is single. Or any of a plurality of them, which are arbitrary.

  Each device constituting the HIS and each device constituting the RIS are connected to the communication network N, respectively. Examples of the communication network N include a network such as a LAN (Local Area Network) or the Internet installed in the hospital. The communication standard used in the communication network N may be any standard such as DICOM (Digital Imaging and Communication in Medicine).

  FIG. 2 is a block diagram showing an internal configuration of the information terminal H1 constituting the HIS or the information terminal R1 constituting the RIS. As the information terminal H1, for example, a diagnostic workstation used for performing input processing such as filling in an electronic medical record while a diagnostician examines a patient can be cited. As the information terminal R1, for example, information used for referring to patient information and examination information of a patient (subject) and performing an operation for inputting accounting information based on the imaging result of the medical image diagnostic apparatus. A terminal can be mentioned. In the embodiment of the present invention, the following description is given on the assumption that the information terminal H1 and the information terminal R1 have the same configuration, but of course, a configuration that is more suitable for the characteristics of each system is adopted. It is also possible to do.

In the information terminal 1, a CPU (Central Processing Unit) 1a, a ROM (Read Only Memory) 1b, a RAM (Random Access Memory) 1c, and an input / output interface 1d are connected via a bus 1e. An input unit 1f, a display unit 1g, a communication control unit 1h, a storage unit 1i, and a removable disk 1j are connected to the input / output interface 1d.

The CPU 1a reads out and executes a boot program for starting the information terminal 1 from the ROM 1b based on an input signal from the input unit 1f, and reads out various operating systems stored in the storage unit 1i. The CPU 1a controls various devices based on input signals from an external device not shown in FIG. 2 via the input unit 1f and the input / output interface 1d. Further, the CPU 1a reads out the program and data stored in the RAM 1c, the storage unit 1i, etc. and loads them into the RAM 1c. At the same time, based on the command of the program read out from the RAM 1c, the imaging processing of the subject and registration of the radiology order A processing device that implements a series of processes such as data calculation or processing.

  As shown in FIG. 2, the input unit 1 f is composed of input devices such as a keyboard and a dial through which an operator of the information terminal 1 inputs various operations, and creates an input signal based on the operation of the operator. It is transmitted to the CPU 1a via the bus 1e. The information terminal 1 may be provided with not only a keyboard but also a dedicated operation panel. In that case, an operation on the operation screen can be performed via an input device on the operation panel.

  The display unit 1g is, for example, a liquid crystal display. For example, the display unit 1g receives an output signal from the CPU 1a via the bus 1e and displays a schema image candidate or order candidate when generating a radiology order, a processing result of the CPU 1a, and the like. It is.

  The communication control unit 1h is a means such as a LAN card or a modem, and is a means that enables the information terminal 1 to be connected to a communication network 4 such as the Internet or a LAN. Data transmitted / received to / from the communication network 4 via the communication control unit 1h is transmitted / received as an input signal or an output signal to / from the CPU 1a via the input / output interface 1d and the bus 1e.

  The storage unit 1i is composed of a semiconductor or a magnetic disk, and stores programs and data executed by the CPU 1a.

  The removable disk 1j is an optical disk or a flexible disk, and signals read and written by the disk drive are transmitted to and received from the CPU 1a via the input / output interface 1d and the bus 1e.

  Although not shown, the database H2 and the database R2 include a processor that performs control such as a CPU, a RAM, and a ROM, and a hard disk that is a storage unit. Various information related to patient information and electronic medical records is stored in the database H2, and necessary information is provided based on an instruction from the information terminal H1, or new information is registered by the information terminal H1. The database R2 stores a radiology order or the like that is the basis of the processing performed so far. In particular, information that serves as a reference when the requesting doctor generates a radiology order is registered as a search condition table or an order candidate search condition table. The requesting doctor who operates the information terminal H1 calls the information registered in the database R2 via the database H2. An engineer who operates the information terminal R1 also accesses the database R2 to process or register information.

  As shown in FIG. 1, the ordering system OS is a system that operates across both the HIS and RIS systems. Specifically, a doctor who examines a patient using the information terminal H1 uses this ordering system OS to generate a radiology order. An engineer or the like takes an image of a patient (subject) based on the generated radiology order and acquires internal information thereof. The ordering system OS is also used when registering the generated radiology order in the database R2.

The ordering system OS includes an HIS information terminal H1 and a database H2, and an RIS information terminal R1 and a database R2. In the embodiment of the present invention, an application program for causing the ordering system OS to function is a database R2.
It is assumed that it is stored in However, it may be stored as a program of the ordering system in the storage unit 1i of the information terminals H1 and R1, or may be stored in the removable disk 1j. Furthermore, the application program may be stored in the HIS database H2 instead of the RIS database R2.

  The application program is activated based on an instruction from the information terminal H1 or the information terminal R1, and is read and executed by the CPU 1a, whereby the ordering means is implemented in the information terminal H1 or the information terminal R1. Become.

  FIG. 3 is a functional block diagram of the ordering system OS in the embodiment of the present invention. The ordering means OA includes a reception unit 41, a search unit 42, a determination unit 43, a registration unit 44, and a transmission unit 45. The receiving unit 41 receives an instruction from the information terminal H1 or the information terminal R1. The search unit 42 searches the database R2 for information necessary for generating a radiology order for a doctor who examines a patient. The determination unit 43 determines the information received by the reception unit 41 and issues an instruction to the search unit 42 or the registration unit 44. The registration unit 44 performs registration in the radiology order database R2. The transmission unit 45 transmits the processing result to the information terminal H1 or the information terminal R1 based on instructions from the search unit 42, the determination unit 43, and the registration unit 44, or is registered in the database R2 therein. The search instruction of the information which has been transmitted is transmitted.

  Next, the generation of the radiology order based on the examination of the patient, the imaging of the subject by the radiology order, and the registration of the radiology order are stored in the flowcharts shown in FIGS. 4 and 7 and the database R2 shown in FIGS. A description will be given using a registered table as an example.

  FIG. 4 is a flowchart showing a flow of radiology order generation in the embodiment of the present invention. A doctor who examines a patient grasps various information about the patient using an actual examination or HIS, or examines a patient using an electronic medical record. Also, as a result of the examination, a radiology order is generated as appropriate, and the radiology department is instructed to obtain internal information of the corresponding patient using the medical diagnostic apparatus R3. This instruction is a radiology order. Thus, the ordering system OS is used when transmitting a radiology order from the doctor to the radiology department.

  In addition, since a doctor who generates a radiology order is also a requesting doctor who requests an order from the radiology department, a doctor who examines a patient and generates a radiology order is hereinafter referred to as a “requesting doctor”. .

  The requesting doctor examines the patient's condition and determines whether or not to generate a radiology order. When it is determined that imaging (acquiring patient internal information) using the medical image diagnostic apparatus R3 in the radiology department is necessary, a radiology order is generated. When generating a radiology order, first, a schema image is created to determine which part of the patient is desired to be imaged. This schema image is an image that schematically shows the form (shape, color, pattern, etc.) of a diagnosis target (for example, a part such as a carotid artery, a peripheral blood vessel, or a heart) of the patient (subject) in image diagnosis. is there. The radiology order is composed of a schema image indicating an affected area and various items such as imaging conditions.

  When the requesting doctor creates a schema image, the information terminal H1 is used to input various items. The input item is, for example, an item specified in the search condition table registered in the database R2. FIG. 5 shows an example of a search condition table. As shown in FIG. 5, for example, “name of expected disease”, “sex”, “age”, “request department”, and “patient status” are listed as items. It has been. The items listed here are merely examples, and other input items may be provided.

  In the search condition table shown in FIG. 5, each schema image and each item for specifying this schema image are shown for each part. For example, when the schema image is registered in the search condition table as “uterus”, two types of “marks” (position information on the schema image) attached to the schema image (X coordinate “30”, Y coordinate “60”), “predicted disease name” is cancer, “sex” is female, “age” is 50, “request department” is gynecology, and “patient condition” is allergy.

  As shown in FIG. 5, a schema image for each part and each coordinate is registered in the search condition table, and a “key number” is assigned to each. The content registered in this search condition table is the content of the order that is the basis when the image is actually taken using the medical image diagnostic apparatus R3. For example, the schema image is “uterus”. A plurality of such data are also registered. Accordingly, only three types of schema images are shown in FIG. 5, but a plurality of schema images are registered for each part and for each different condition item, and the conditions are met according to the request of the requesting doctor. A schema image is presented.

  Even if the schema image shows the same part, if the contents of other input items such as “predicted disease name” are different, it is regarded as different information, and a separate key number is given. Therefore, as described above, information having a plurality of key numbers may be registered in the search condition table even in the same part.

  When the requesting doctor confirms that the various items described above have been input to create the schema image via the input unit 1f by the requesting doctor (ST1 shown in FIG. 4), the determining unit 43 causes the searching unit 42 to Instructs the corresponding schema to be searched. Based on this instruction, the search unit 42 searches for a schema image that matches various conditions input in the search condition table (ST2). Since a plurality of schema images are registered in the search condition table as described above, a schema image related to a matching part is searched.

  As a result of the search by the search unit 42, the determination unit 43 determines whether the requested doctor has searched for a desired schema image (matching various input conditions) (ST3). As a result, when a schema image close to the input condition is searched (YES in ST3), the candidate doctor image is displayed on the display unit 1g in order to assist the requesting doctor in creating a new schema image (ST4). ).

  Therefore, when the requesting doctor intends to create a schema image when generating a radiology order, the display unit 1g of the information terminal H1 is close to the input conditions from the previous radiology orders registered in the database R2. A schema image is displayed (ST5). Therefore, it is not necessary for the requesting doctor to create a schema image from scratch, and from the displayed schema image candidates, select a schema image that has a close display in light of the current symptom, and simply mark the affected area with radiation. It is possible to indicate the position where the department wants to take a picture on the schema image. As described above, since an example of the schema image is displayed based on the conventional radiology order, it is possible for the requesting doctor to save time for creating the schema image.

  As for the schema image that can be selected by the medical doctor displayed on the display unit 1g, only the schema image may be displayed, or the mark displayed on the schema image may be displayed. good. In the latter case, erase the previous mark and add a new one, or move the displayed mark according to the patient's condition and re-position the affected area (the position you want the radiology department to take) It can be displayed.

The requesting doctor marks a desired position on the selected schema image. The determination unit 43 grasps information on the mark position by the requesting doctor (ST6). Based on the information obtained by the determination unit 43, the determination unit 43 searches the search unit 42 for a corresponding schema image in the search condition table (ST7).

  Here, since the search is performed with reference to the mark position information in addition to the schema image, the search is basically performed only when both the schema image and the mark position information match. However, if the search is performed only when both the schema image and the mark position information match, the search condition may be too strict. In particular, regarding the information on the mark position, depending on the affected part of the patient, the schema image can be searched, but the mark position is different, so that an effective search result cannot be presented to the requesting doctor. The operation of the ordering system OS under such a search condition may lack practicality.

  Therefore, it is possible to set the search condition loosely in advance, and it is possible to set so as to present more schema images to the requesting doctor. Specifically, regarding the information on the positions marked on the schema image, the schema images that are not completely coincident and that include the position information included in a certain area are assumed to have the position information designated by the requesting doctor, and those schemas are included. Make it possible to present images.

  For example, in the case of the uterine schema image indicated by the key number “001” in FIG. 5, the mark position information originally registered in the search condition table is “mark X: 30” and “mark Y: 60”. When a perfect match is obtained with respect to the schema image and the mark position, the client doctor selects the schema image of the uterus, and the key number “ The information “001” is not searched.

  Therefore, regarding the information on the mark position, it relates to the uterus including “mark X: 30” and “mark Y: 60”, for example, corresponding to the range of “mark X: 20-40”, “mark Y: 50-70” If a schema image is registered, the information is also searched. By setting and controlling in this way, it is possible to provide a convenient ordering system OS that is easy to use for generating a radiology order for the client doctor.

  Based on the information from the search unit 42, the determination unit 43 determines whether the search unit 42 has searched for the corresponding information from the search condition table (ST8). If the determination unit 43 determines that the search unit 42 has searched for the corresponding information (YES in ST8), the search unit 42 further retrieves information associated with the corresponding information from the order candidate search condition table. Search is performed (ST9).

  Specifically, the “information linked to the corresponding information” means, for example, that the search unit 42 uses the uterus as the schema image from the search condition table, “mark X: 30” as the mark position information, and “mark Y : 60 ”, the same key number registered in the order candidate search condition table as information that matches the key number attached to this information, that is, linked information is searched. It is information having “001”.

  FIG. 6 is an explanatory diagram showing an example of an order candidate search condition table in the embodiment of the present invention. In this “order candidate search condition table”, information for presenting a plurality of orders that assist the order creation to the requesting doctor when the requesting doctor generates a radiology order is registered. That is, in the “order candidate search condition table”, a radiology order that has been generated so far or a radiology order that has been modified for imaging is registered. Specific items registered include “key number”, “type”, “part”, “body position”, “direction”, “imaging method” in the order candidate search condition table shown in FIG. There are nine types of items such as “shooting room”, “number of times of execution”, and “last execution date”.

  These items can be arbitrarily set, and are not particularly limited to the items shown in FIG.

  Among these, as described above, the “key number” corresponds to “information associated with the corresponding information”, and is linked to the “key number” in the search condition table in a one-to-n relationship. Therefore, for example, when the requesting doctor selects one of the schema images displayed on the display unit 1g, an order to which the same key number as the key number assigned to the selected schema image is assigned. One or more candidates are displayed selected from the order candidate search condition table.

  Among the registered items, “type” is the type of the medical image diagnostic apparatus R3, and “part” indicates a part to be imaged by the medical image diagnostic apparatus R3. “Position”, “Direction”, and “Shooting method” are conditions for which settings are required for shooting. The “imaging room” indicates in which imaging room the imaging based on the radiology order was performed. “Number of executions” indicates the number of shootings under the set conditions, and “Last execution date” indicates the latest date among the shooting dates under the conditions.

  Therefore, even if the same imaging target is “uterus”, there are a plurality of variations depending on the “type”, “position”, and “direction” of the imaging. For example, even if an order is assigned with the same key number “001”, there are three types of orders in the order candidate search condition table shown in FIG. 6, and shooting has been performed based on any of these orders so far. Has been done. However, there is a difference in the “number of executions”. For example, an order that has been performed “20 times”, an order that has been performed “15 times”, and an order that has been performed only once are registered.

  When the search unit that has searched the order candidate search condition table based on the instruction of the determination unit 43 sends the search result to the determination unit 43, the determination unit 43 receives the corresponding order candidate and sends it to the requesting doctor via the display unit 1g. On the other hand, it is displayed as an order candidate that can be selected (ST10). The requesting doctor selects an appropriate order for the current patient from the displayed order candidates.

  For example, it is possible to set the display unit 1g to display the order candidates in the “execution count” order registered in the order candidate search condition table. Thus, by displaying in order of increasing number of executions, it is possible to generate a more appropriate radiology order for a patient having a symptom represented by the schema on the schema.

  The display method of the order candidates is not limited to the “number of times of execution” order. For example, the order candidates can be displayed in order of “type” or “last execution date”. How to display them generates a radiology order. It depends on the requesting physician. Of course, if the request conditions do not match the displayed order candidates, the requesting doctor can of course set all the order (imaging) conditions.

  When the requesting doctor selects from the order candidates or confirms that the condition is arbitrarily set, the determination unit 43 transmits the radiology order to the database R2 (ST11). This transmission is performed, for example, when the requesting doctor clicks a transmission button displayed on the information terminal H1 operated by the requesting doctor.

  If a schema image to be presented when the requesting physician generates a radiology order cannot be retrieved (NO in ST3), a new schema cannot be created because it is necessary to create a new schema image that has not been registered so far. A screen for creating an image is displayed (ST12). On this screen, the client doctor creates a schema image that matches the patient's symptoms.

  Also, when a schema image has been registered but a schema image having position information approximate to the mark position information is not registered (NO in ST8), or when a new schema image is created as described above Displays a screen for inputting various shooting conditions (ST13). The requesting doctor sets necessary conditions using this input screen. When the necessary conditions are input, the generated radiology order is transmitted to the database R2 (ST11).

  This is the end of the procedure in which the requesting doctor generates a radiology order and transmits it to the radiology department. Next, the flow of processing performed in the radiology department based on the transmitted radiology order will be described.

  FIG. 7 is a flowchart showing a flow of processing based on the radiology order generation generated in the embodiment of the present invention and the registration of this radiology order. The transmitted radiology order is received and stored in the database R2 (ST21). The received radiology order may be automatically displayed on the display unit 1g of the information terminal R1, or the information terminal R1 appropriately obtains the radiology order stored in the database R2. It can also be.

  An engineer who actually performs imaging or the like in the radiology department confirms the radiology order displayed on the information terminal R1. Depending on the radiology order created by the requesting physician, conditions that are difficult to actually perform imaging using the medical image diagnostic apparatus R3 are set, or better imaging conditions are set based on the experience of the technician. This is because it may be possible.

  Accordingly, the determination unit 43 confirms whether or not the radiology order stored in the database R2 has been modified by the technician (ST22). This is determined by the presence or absence of setting item change information.

  In particular, when there is no correction in the radiology order sent from the requesting doctor, imaging of the patient (subject) is performed based on the received radiology order. On the other hand, since appropriate radiography cannot be performed with the received radiology order as it is, if the technician modifies the radiology order from a certain point of view, the patient (subject) based on the revised radiology order. Is taken (ST24).

  The determination unit 43 confirms whether or not the medical image diagnostic apparatus R3 has finished imaging based on the radiology order (ST25). If the end cannot be confirmed during imaging or the like (NO in ST25), the process is left in a standby state. If the end of imaging is confirmed, the process proceeds to a registration process in the radiology order database R2 that is the source of imaging.

  In registering a radiology order, first, the determination unit 43 confirms whether or not the radiology order to be registered is already registered in the database R2. For this purpose, first, it is determined whether or not a schema image of a radiology order to be registered is registered in the search condition table (see FIG. 5) (ST26).

  Here, when determining the presence or absence of registration, it is determined not only whether or not the same schema image is registered, but also whether or not the same information is registered regarding the mark position information. . That is, it is determined whether information that matches both the schema image and the mark position information is registered in the search condition table. This is because increasing the number of order candidates to be presented to the requesting doctor who generates the radiology order leads to further saving the labor of creating the schema image when the radiology order is generated by the requesting doctor.

  If the information about the schema image and the mark position is registered in the search condition table (YES in ST26), it is next checked whether or not the order as the imaging condition is registered in the order candidate search condition table ( ST27). Here, if even one of the condition items is different from the order in the order candidate search condition table, it is determined that the radiology order is not registered in the order candidate search condition table.

  Note that it is possible to arbitrarily set which condition item is judged to be registered in the order candidate search condition table even if they do not match. This is because the condition item varies depending on, for example, a medical institution that has introduced the RIS, and there may be a case where a tendency of the condition item is also observed.

  When the determination unit 43 determines that the order as the imaging condition is registered in the order candidate search condition table (YES in ST27), the registration unit is configured to count up and register the number of executions of the corresponding order. 44 is instructed (ST28). At the same time, the registration unit 44 is instructed to update the last execution date (ST29).

  When the schema image of the radiology order received by the database R2 is not registered in the search condition table (NO in ST26), a new schema image is registered in the search condition table via the registration unit 44 (ST30). . At that time, information on the mark position and each item such as an assumed disease name are also registered. Further, the determination unit 43 assigns a new key number.

  When a new schema image is registered in the search condition table, the determination unit 43 further instructs the registration unit 44 to register related conditions as new order candidates in the order candidate search condition table (ST31). In this case, the information registered in the order candidate search condition table is assigned the same key number as the key number assigned in the search condition table.

  On the other hand, when the schema image and the mark position information are registered in the search condition table, but the order is changed by the requesting doctor or engineer (NO in ST27), the information is registered. Unit 44 registers the modified order as a new order in the order candidate search condition table (ST31). At this time, the key number assigned to the new order is assigned the same key number as the original (no change) schema image. By assigning the key number in this way, when the requesting doctor selects a schema image when generating a radiology order in the future, it is possible to present order candidates with more variations.

  By adopting the configuration described above and operating the HIS and the RIS in cooperation, an ordering system that facilitates easy creation of a radiology order by a client doctor and a user-friendly support, and a radiation information management system including the ordering system, A medical information management system can be provided.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. For example, it is possible to change the components of the ordering system OS shown in FIG. Specifically, for example, as shown in the modification of FIG. 8, the HIS database H2 can be used only as the HIS database regardless of the ordering system OS. In this case, all information when using the ordering system OS is stored in the database R2 of the RIS. Furthermore, as shown in the modification of FIG. 9, it is possible to integrate the HIS and RIS databases into a shared database 5. In this case, information regarding all systems constructed in the medical institution is registered in the shared database 5.

  Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine the component covering different embodiment suitably.
