Description

  The present invention relates to an operation support system for a person who uses a medical diagnostic apparatus and a medical diagnostic apparatus equipped with the system.

  In recent years, for example, an X-ray diagnostic apparatus, a CT (computed tomography) apparatus, an ultrasonic diagnostic apparatus, a magnetic resonance diagnostic apparatus, a gamma camera, a PET (positron-emission tomography), etc. Medical diagnostic devices have become widespread and have been introduced into many medical institutions.

  However, some medical institutions do not frequently use these introduced medical diagnostic devices, or use only specific functions among various functions provided in these medical diagnostic devices. In some cases, it is not used, and medical personnel (users) such as doctors, nurses, and technicians may forget how to operate the medical diagnostic apparatus. In addition, a plurality of medical workers who use the medical diagnostic apparatus may be replaced at regular intervals, and it may take time to become familiar with the operation of the medical diagnostic apparatus.

  As an operation support method performed for the operator of the device in such a case, for example, the operation history stored for each operator by the operation history storage unit is referred to, and the operator identified by the identification unit is handled. There has been proposed an operation support system capable of providing appropriate operation support according to the operation status of each operator by providing means for setting the operation environment (see Patent Document 1). Also, an information terminal device that predicts a suitable operation next to a specific operation input by the user based on a previous operation history performed by the user, and supports the operation input by the user according to the prediction to improve operability. An operation support and an operation support program have also been proposed (see Patent Document 2).

In addition, collecting operational data from medical devices and analyzing and disclosing data that represents potential training needs can require or benefit from specific training for specific equipment and types of equipment. There has also been proposed an automatic identification method for training needs of medical staff who can specify a user who receives the training or schedule a training (see Patent Document 3).

  However, in Patent Documents 1 and 2, in order to organize the operation history information, the operation history information is identified using the operation date and time and the information of the operator, and stored in the operation history storage unit or the operation history storage unit. Operation support is supposed to be based on the previous operation history performed by the operator, and the operation history information is reused when the user first contacts the device or when the previous operation history is very small. Therefore, proper operation support may not be performed.

  In Patent Document 3, a method for using an operation history limited to medical devices has been proposed. However, specific means regarding how operation history information is managed is clearly described. However, the above-mentioned problem cannot be solved.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to extract information necessary for operating a medical diagnostic apparatus from information of an operation history and manage it in units of examination work. Therefore, even if a user who uses low-frequency functions or a user who has little experience in using a medical diagnostic device forgets to operate the medical diagnostic device, he / she receives operation support based on past operation history information. Accordingly, it is an object to provide an operation support system capable of improving the operability of the medical diagnostic apparatus and a medical diagnostic apparatus equipped with the system.

The feature according to the embodiment of the present invention is transmitted from the operation information collecting means for collecting the operator information from the operator identifying means for identifying the operator who operates the apparatus and the information regarding the operation of the apparatus in the operation support system. Operation information managing means for managing the operation information, operation information managing means for managing operation information transmitted from the operation information collecting means for collecting information related to the operation of the operator, and operations registered in the operation information managing means An operation sequence extracting unit for extracting information and acquiring operation information matching the operation information from the operation information registered in the operation information managing unit, and an operation for registering the operation sequence extracted by the operation sequence extracting unit Registered in the sequence management means, the operation sequence extracted by the operation sequence extraction means and the operation sequence management means And are compared with the sequence of operations so far, when the difference exceeds a predetermined value, notify the operator in advance in order to register the extracted operation sequence by operating sequence extraction means as a new operation sequence An operation sequence registering means for registering the operation sequence extracted by the operation sequence extracting means as a result of comparison by the operation sequence comparing means to the operation sequence managing means, and an operation registered in the operation sequence registering means And an operator specifying means for selecting an operator who has performed an operation based on the operation sequence to be referred to from among the sequences.

  According to the present invention, information necessary for operating the medical diagnosis apparatus is extracted from the operation history information and managed in units of examination work, so that a user or a medical diagnosis apparatus used for low-frequency functions can be managed. An operation that can improve the operability of the medical diagnostic apparatus by receiving operation support based on past operation history information even if a user with little experience forgets to operate the medical diagnostic apparatus A support system and a medical diagnostic apparatus equipped with the system can be provided.

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

  In the medical diagnostic apparatus 1 shown in FIG. 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. . The input / output interface 1d is connected with input means 1f, display means 1g, communication control means 1h, storage means 1i, removable disk 1j, and drive unit control means 1k, and drive unit control means 1k. Thus, each drive unit 11 of the medical diagnostic apparatus 1 is controlled.

  The CPU 1a reads out and executes a boot program for starting up the medical diagnostic apparatus 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. Further, the CPU 1a controls various devices based on an input signal from an external device not shown in FIG. 1 via the input means 1f or the input / output interface 1d, or is stored in the RAM 1c, the storage means 1i, or the like. This is a processing device that reads a program and data and loads the program and data into the RAM 1c, and realizes a series of processing such as data calculation or processing based on a program command read from the RAM 1c.

  The input unit 1f is configured by an input device such as a keyboard and a mouse through which an operator of the medical diagnostic apparatus 1 inputs various operations. The input unit 1f creates an input signal based on the operation of the operator and sends the CPU 1a via the bus 1e. Sent to. The medical diagnostic apparatus 1 is provided with a dedicated operation panel as well as a keyboard and the like, and an operation screen can be operated through an input device on the operation panel. The display unit 1g is, for example, a liquid crystal display, and is a unit that receives an output signal from the CPU 1a via the bus 1e and displays a processing result of the CPU 1a.

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

  The storage means 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.

  In the storage unit 1i of the medical diagnostic apparatus 1 according to the embodiment of the present invention, for example, a program and data such as a navigation program for assisting the operator of the medical diagnostic apparatus 1 are stored. In addition, the operation support means 2 is mounted on the medical diagnostic apparatus 1 by reading a navigation program or the like into the CPU 1a of the medical diagnostic apparatus 1 and executing it.

  In the following, a case where a navigation program or the like is stored in the storage unit 1i will be described as an example, but the navigation program or the like may be stored in the removable disk 1j.

  As shown in FIG. 2, the operation support means 2 includes an operation information collection means 2a, an operation information management means 2b, an operation information collection means 2c, an operation information management means 2d, an operation sequence extraction means 2e, and an operation sequence. The comparison unit 2f, the operation sequence management unit 2g, and the operation sequence registration unit 2h are included.

  The operation information collecting unit 2a is for collecting (monitoring) the operation of the input unit 1f of the medical diagnostic apparatus 1. That is, operation information is collected by detecting (hooking) an event generated by the input means 1f using a function provided by an operating system, a window management system, or the like. After that, the operation information is converted into a text format or the like, date / time information, information on the operator who is currently logged on, etc. are added and recorded using the operation information management means 2b.

  For example, as shown in the operation information list in FIG. 3, one operation is recorded in one line along with a time stamp. In the embodiment of the present invention, this time stamp is recorded in year / month / day / hour / minute / second / millisecond. The operation information includes, for example, an operation name indicating whether the operation is related to a keyboard or a pointing device, and additional information indicating details of the operation according to the operation. As supplementary information, for example, “WM_KEYDOWN” is an operation relating to the keyboard, indicating that the key has been pressed, and “0x0041” thereafter indicates the “A” key. “WM_LBUTTONDOWN” is an operation indicating that the left button of the pointing device is pressed, and the subsequent (391, 214) indicates the position coordinates where the left button is pressed.

  The operation information collecting unit 2c collects (monitors) what processing has been executed in response to an operation on the input unit 1f by an operator, a physical button operation, or communication from a network or a serial cable. ). This is performed by using the operation information management unit 2d by adding date / time information and the like to the operation representing the type of process as a process record by the business application.

  For example, as shown in the operation information list of FIG. 4, this operation information includes “date and time”, “operation item”, “operation content”, “inspection ID”, and “operator” from the left in the present embodiment. An item is provided, and one process is recorded in one line together with a time stamp. For example, it is recorded in “2006/01/10 11:24:54” that “user A” has pressed the “inspection selection button”. In this operation content, an examination assigned with the number “6638” as the “inspection ID” is selected.

  Next, at “2006/01/10 11:24:55”, “User A” who is the same operator performs shooting by pressing the “Start / End button” for the inspection with “Examination ID” of “6638”. Has been recorded. When this “start / end button” is pressed, image shooting is performed, and the “shooting number” is “001”. When the “start / end button” is pressed again, shooting is completed. Then, the next shooting plan is selected by the next shooting button, and the shooting procedure is repeated (“shooting number = 002”).

  Furthermore, in the operation information list, the operator selects the left window from two image display windows shown in the screen example of FIG. 9 to be described later, and adjusts the window width (WW) to adjust the gradation of the photographed image. ) And the window level (WL) are changed, and it is recorded that the right end window is selected and then the inspection end button is pressed. This completes a series of inspections.

  In the operation information list in FIG. 4, the operation of the operator is recorded along the above-mentioned items, but the type of information and the recorded content recorded in the operation information management means 2d are not particularly limited. It can be arbitrarily determined as necessary. In the medical diagnostic apparatus, since generally captured image information is managed in units of examination, the medical diagnostic apparatus 1 has information for identifying examinations in the medical diagnostic apparatus 1 in order to manage each examination unit, For example, it is managed by the inspection ID. The operation information collection unit 2c also records this inspection ID as operation information in the operation information management unit 2d.

  The operation information management unit 2b or the operation information management unit 2d may be managed as a file as an operation log. A management table is prepared in a database management system or the like, and one operation information is stored in one record. It doesn't matter. When managing as a file, the operation log is appended to the file.

  The operation sequence extraction unit 2e is based on the operation information of the input unit 1f of the medical diagnostic apparatus 1 recorded in the operation information management unit 2b and the operation information performed by the operator recorded in the operation information management unit 2d. One or a plurality of operation histories performed for examinations having the same examination ID are extracted. In the embodiment of the present invention, the extracted operation history is hereinafter referred to as “operation sequence”.

  The flow of operation sequence extraction by the operation sequence extraction means 2e will be described mainly using the other drawings as appropriate, mainly based on the flowchart of FIG.

  The operation sequence extraction unit 2e first extracts one piece of operation information in the “operation item definition file” recorded in the operation sequence extraction unit 2e (ST1). As shown in FIG. 6, this “operation item definition file” is a file that defines the operation items to be noted from among the operations by the operator, such as “shooting button” and “start / end button”. The operation sequence extraction unit 2e compares the character string of the operation item defined in the operation item definition file with the character string recorded in the “operation item” of the operation information management unit 2d, and extracts the matching operation information. .

  Next, in order to identify which of the basic functions of the medical diagnostic apparatus 1 such as photographing and observation is used, the medical diagnostic apparatus 1 based on the state transition diagram shown in FIG. Is determined (ST2). This state transition diagram is a diagram showing the transition of the operation state of the medical diagnostic apparatus 1 from when the power supply is turned on to when the power supply is turned off until the operation is completed. Items and operation information of the medical diagnostic apparatus 1 are defined.

  For example, in the state transition diagram of FIG. 7, the medical diagnostic apparatus 1 shifts to a “standby” state when the activation process is completed. When the “shooting button” is pressed by the operator in the “standby” state, the operation is recognized and the state is changed to the “patient examination” state. Further, since it is possible to recognize that the imaging job in the examination has been started by an operation of pressing the “imaging button”, the time information of the operation information is recorded as the start time of the imaging job (ST3). That is, this operation is collected as the operation information of the operator by the operation information collecting means 2c. For example, as shown in the operation information list of FIG. 4, the operation is “2006/01/10 11:24:52”. The fact that “user A” has pressed the “shooting button” is recorded in the operation information management means 2 d.

  Further, it can be said that the operation of pressing the “imaging button” is one of the events generated by the input unit 1f of the medical diagnostic apparatus 1, and this operation information is obtained via the operation information collection unit 2a, for example, as shown in FIG. Is recorded in the operation information management means 2b together with a time stamp as in the operation information list shown in FIG. On the other hand, when the “observation button” is pressed from the “standby” state, the state transitions to the “image observation” state.

  When transitioning to the “patient examination in progress” state, a screen as shown in FIG. 8 is first displayed. FIG. 8 and the next FIG. 9 show examples of basic screens displayed on the display means 1 g of the medical diagnostic apparatus 1. For example, in the medical diagnostic apparatus 1 according to the embodiment of the present invention, buttons for selecting operations to be performed in the medical diagnostic apparatus 1 such as a reservation button for examination reservation are arranged on the left side of the screen. In addition, on the upper right side, for example, a list part that displays a list of scheduled examinations, patient imaging plans, and the like, and an image display window that displays captured images for each part are displayed on the lower side. Has been.

  When the examination selection button is pressed in a state where the first examination in the examination list shown in the screen example of FIG. 8 is highlighted, the examination ID is fixed, and the specific imaging plan shown in FIG. A screen for displaying the captured image appears. Note that the examination ID (for example, “6638” shown in FIG. 8) has been confirmed by the operation for changing to the screen of FIG. In addition to “date and time” and “operation item”, the fact that the examination having the examination ID “6638” is selected as the “operation content” and the “inspection ID” is recorded (ST4). At the same time, the operation of the medical diagnostic apparatus 1 is also recorded as operation information in the operation information list (see FIG. 3).

  In the screen of FIG. 9, a list of shooting plans is displayed in the list portion, and the top list is highlighted. Subsequently, the “inspection start / end button” is pressed, and it is determined whether or not the inspection ID in this operation matches the inspection ID recorded so far (ST5). Since it can be determined that the inspection is different from the inspection performed so far, the operation information in the operation item definition file is extracted again by returning to step 1. On the other hand, if the examination IDs match and the occurrence time is after the job start time, the operation information is acquired from the operation information management means 2d, and the event closest in time to the operation information occurrence time is obtained. The operation information is extracted from the operation information management means 2b (ST6). Then, a set of operation items and operation information including the order information is stored (ST7).

  In the state of “patient examination” in the state transition diagram shown in FIG. 7, when an operation of pressing the “examination end button” is performed, it is first determined whether or not the above-described processing for all operation information has been completed. (ST8) If completed, the process returns to the “standby” state, so that it can be recognized that this inspection work has been completed. Therefore, the time of the inspection work is recorded as the work end time (ST9), and the operation sequence extracting means 2e rearranges the combinations of the time, inspection items, and event information stored so far in order of one operation. It associates and stores as a sequence (ST10). That is, for example, as shown in FIG. 10, information on an operation by the operator (for example, “examination selection button”) and operation information corresponding to the operation (for example, “WM_LBUTTONDBCLK (281, 164)”) are associated with each other. The operation sequence extraction means 2e is an operation item in the operation item definition file and matches the operation item listed in the operation information list of FIG. The above steps are repeated for each operation.

  In the embodiment of the present invention, it is determined that the operation group is a group of operations using the inspection ID and the operation occurrence time as the operation information selection rule. Not only the case where the examination ID and the occurrence time are used, but other information recorded in the operation information may be used. In addition, for example, the date of the previously processed information may be stored, and information after that date may be processed so that the operation information and the operation information that have already been confirmed are not redundantly processed.

  The operation sequence comparison unit 2f compares the operation sequence acquired by the operation sequence extraction unit 2e (see FIG. 10) with the operation sequences performed so far stored in the operation sequence management unit 2g. Then, after the comparison, how much the operation sequence extracted by the operation sequence extraction unit 2e is a new operation sequence is calculated from the operation sequences stored in the operation sequence management unit 2g. That is, the difference between the two is replaced with “distance” for convenience, and if the distance is smaller than a predetermined value, it is determined that the two are similar, and if the distance is larger than that value, it is determined that the distance is new.

  Specifically, for example, when comparing the operation sequences of “operation sequence management means operation sequence” and “operation sequence extraction means operation sequence”, the first operation sequence and the last operation sequence are different, When the distance is infinite (cannot be compared) and the first operation sequence and the last operation sequence are the same, the order of appearance of the intermediate operation sequences is compared, and the total number of operation sequences that do not match is operated. Defined as the distance between sequences.

  For example, FIG. 11 will be described as an example. FIG. 11 shows the “operation sequence of the operation sequence management means” and the “operation sequence of the operation sequence extraction means” as (a) and (b) divided into two upper and lower stages. When two operation sequences exist, the operation sequence is extracted according to a predetermined state transition, so that the first “operation item / event” and the last “operation item / event” are not the same. Returns a number (eg, 9999) determined to represent infinity without comparison. Next, after the “operation item / event” at the beginning of the operation sequence is associated with the last “operation item / event”, 2 of the operation sequences recorded in the “operation sequence of the operation sequence management means” as the comparison source The “operation item / event” after the first and the “operation item / event” after the second operation sequence recorded in the “operation sequence of the operation sequence extraction means” are sequentially compared. Corresponding to the same “operation item / event”.

  The “operation sequence of the operation sequence management means” in FIG. 11A stores 1 to 8 operation sequences, and the operation information and the operation information are associated with each other. On the other hand, in the “operation sequence of the operation sequence management means”, the “operation sequence extraction means operation sequence” lacks the procedures 5 to 7 recorded in the “operation sequence management means operation sequence”. The operation sequence is extracted. In other words, the “operation sequence of the operation sequence extraction unit” has three operations less than the “operation sequence of the operation sequence management unit”, and this state is set as “−3” as the “distance”.

  In addition, eight operation sequences are recorded in the “operation sequence of the operation sequence management unit” in FIG. 11B, but the “operation sequence of the operation sequence management unit” is included in the “operation sequence of the operation sequence extraction unit”. Three new operation sequences are added between the seventh and eighth operations. This state is set to “+3” as “distance”. Assuming that the threshold value designated in advance is 1, for example, it is determined that the “operation sequence of the operation sequence extraction unit” in FIG. 11 is a new operation sequence that is not similar to each other.

  The calculation of the distance between operation sequences may be performed by assigning a weight to each operation item and calculating in consideration of this weight, or by calculating the weight in consideration of the order of appearance. It doesn't matter how. In addition, a calculation method may be used in which the distances are sequentially associated with the distance calculation, and different numbers are used as the distances. Further, the threshold for determining whether or not the operation sequence is a new one can be arbitrarily determined by the operator of the medical diagnostic apparatus 1.

  The operation sequence registration unit 2h notifies the operator that a new operation sequence has been detected when the operation sequence extraction unit 2e determines that the operation sequence is a new operation sequence using the above-described calculation method. The operator is inquired about whether or not to register the operation sequence. FIG. 12A shows an example of a screen for notifying the operator that a new operation sequence has been detected. In this screen example, a button for selecting whether or not to register a new operation sequence in the operation sequence management means 2g and details about the operation sequence determined to be the new operation sequence shown in FIG. 12B are confirmed. There is a button that you can do. On this detailed screen, an ID or name for identifying the operation sequence may be assigned, or a classification name for classifying the operation sequence may be assigned so that the search can be performed hierarchically. . When the operator registers a new operation sequence, the new operation sequence is registered (recorded) in the operation sequence management means 2g by pressing a registration button (“YES” button in FIG. 12).

  In FIG. 12, after the operator is notified that a new operation sequence has been detected, the screen configuration allows the operator to select whether to register or not. However, if a new operation sequence is detected, the operator After the notification, the operation sequence registration unit 2h may automatically register. Further, the operation sequence registration unit 2h may periodically inquire the operation sequence extraction unit 2e about the presence or absence of a new operation sequence, and perform processing after being notified of registration of a new operation sequence from the operation sequence extraction unit 2e. It doesn't matter. Alternatively, the operation sequence extraction unit 2e may be inquired at a designated timing such as just before the medical diagnostic apparatus 1 is stopped. Further, for example, a button for registering an operation sequence or the like is provided on the operation screen shown in FIG. 8 or FIG. 9, and when the button is executed, a method of performing operations after extraction based on the operation history up to that point or the like Good. Further, the notification that a new operation sequence is detected to the operator may be notified according to the state of the medical diagnostic apparatus, or may be notified at an arbitrary timing. Furthermore, in the embodiment of the present invention, the novelty is determined mechanically, but the mechanical determination is not performed, and a means (such as a confirmation button) for confirming whether there is a new operation sequence is provided. When the confirmation method is selected, for example, the following operations are performed for all examinations performed on the same day, and the list of extracted examination operation sequences and the calculated new degree are displayed together to confirm the contents. The user can determine whether or not to register at that time.

  The operation sequence management means 2g is for storing and managing the operation sequence extracted by the operation sequence extraction means 2e. The operation sequence management unit 2g stores an operation sequence registered in advance and a new operation sequence registered by the operation sequence registration unit 2h described above. Information stored in the operation sequence management means 2g includes an ID, a name, a registration date and time, etc., and a sequence of operation items and operation information is registered for each operation sequence.

  If the operation item can be uniquely identified, for example, a number may be used as an identifier or a name may be assigned to identify the operation item. Also, in order to store the operation sequence, it may be easily managed with a directory structure. Information other than the identification ID, name, registration date and time, operation sequence (sequence of operation items and events) is recorded. It doesn't matter.

  By adopting such a configuration, the information necessary for operating the medical diagnostic device is extracted from the operation history information and managed in units of examination work, so that users and medical diagnosis used for low-frequency functions Even if a user with little experience in using the device forgets to operate the medical diagnostic device, it is possible to improve the operability of the medical diagnostic device by receiving operation support based on the past operation history information. It is possible to provide an operation support system that can be used and a medical diagnostic apparatus that includes the system.

  In the embodiment of the present invention, the medical diagnostic apparatus 1 has been described as an example. For example, the HIS (Hospital Information System), RIS (Radiological Information System), and PACS (Picture) which are not the medical diagnostic apparatus 1 are described. Archiving Communication System). Alternatively, two or more of these may be combined with the medical diagnostic apparatus 1 and may be configured as a network system by performing communication connection such as the Internet.

  In addition, operator identification means for identifying an operator who is currently operating the medical diagnostic apparatus 1 may be provided. The identification method may be a method using a biometric feature such as an operator's fingerprint or an IC card. Etc. can be employed.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description of the same components is omitted because it is duplicated.

  In the second embodiment, an operation sequence selection unit 2i and an operation sequence reproduction unit 2j are added to the operation support unit 2 in the first embodiment.

  The flow of operation support (navigation) in the second embodiment will be described below.

  The operation sequence selection means 2 i is a means for selecting an operation that the operator wants to provide operation support when the operator operates the medical diagnostic apparatus 1. FIG. 14 is a screen example showing a list of operations for performing operation support. The operation sequence selection unit 2i acquires information on the registered operation sequence from the operation sequence management unit 2g (see ST21 in FIG. 15), and displays a name or identification ID for identifying the operation sequence and a registration date. . As a result, the operation sequence that the operator wants to refer to is selected (ST22). When the “detail button” is pressed by the operator, a series of “operation items” registered in the operation sequence is displayed. For example, in the screen example of FIG. 14, “head general examination” is listed as an operation that can be supported in the top row, and it is shown that this examination was performed on “April 5, 2005”. .

  When an operation sequence desired to be supported by the operator is selected (ST22), for example, the selected operation name is reversed on the screen, and the operation sequence reproducing means 2j uses a name or a name for identifying the operation sequence. The identification ID is acquired from the operation sequence selection means 2i (ST23). Further, the operation sequence reproduction means 2j may acquire the detailed information of the operation sequence directly from the operation sequence management means 2g based on the information from the operation sequence selection means 2i.

  Further, the operation sequence reproducing unit 2j acquires the operation information detected by the operation information collecting unit 2a, and also acquires the operation information of the operator detected by the operation information collecting unit 2c (ST24). When the operation information matches the operation item described in the operation item definition file, the operation information and the operation information are compared with the operation item registered in the selected operation sequence (ST25). Then, the operation information and the operation information are acquired again to grasp the currently performed operation (ST26), and the navigation is started (ST27). Specifically, based on the operation information of the next operation item, in order to prompt the next operation, for example, the pointing device is moved to the position information described in the event information, or the operation information is For example, a chip help is displayed at the described position information to assist the operation of the operator. It is determined whether or not the operation by the operator is finished (ST28), and if the operation is continuously performed, the navigation is continued. On the other hand, when the operation is finished, the navigation is also finished (ST29).

  FIG. 16 is a screen example showing an example of operation support. In FIG. 16, a message is displayed near the button to be operated next. In addition to this, as a method of operation support, for example, the next operation target to be performed only by selecting the button by changing the density of the button to be operated next, or providing the “next operation” button is provided. There are also methods for displaying and automatically executing operations. In the second embodiment, the navigation on the operation screen has been described. However, in addition to the method of projecting on the operation screen, for example, the operation support can be performed by voice guidance.

  In this way, by extracting information necessary for operating the medical diagnostic apparatus from the operation history information and managing it in units of examination work, users and medical diagnostic apparatuses used for low-frequency functions Even if a user who has little experience in using the device forgets to operate the medical diagnostic apparatus, it is possible to improve the operability of the medical diagnostic apparatus by receiving operation support based on the past operation history information. An operation support system and a medical diagnostic apparatus equipped with the system can be provided.

(Third embodiment)
Next, a third embodiment of the present invention will be described. In the third embodiment, the same components as those described in the first or second embodiment are denoted by the same reference numerals, and the description of the same components is duplicated. Omitted.

  The flow of large operation support is the same as that of the above-described embodiment. However, in the third embodiment, as shown in FIG. 17, in particular, the operator specifying means is included in the operation sequence registration means 2h in the operation support means 2. By connecting 2k, when performing operation support for the operation of the medical diagnostic apparatus 1, a registered operation sequence can be specified for each operator.

  That is, when a certain operator requests operation assistance for the operation of the medical diagnostic apparatus 1, not only the operation procedure can be selected, but also the operator who performed the operation to be referred to can be specified. As a premise of specifying the operator who has performed the operation to be referred to in this way, the operator specifying means 2k filters the operation sequence of the operator registered in the operation sequence registration means 2h.

  For example, the operator specifying means 2k displays a list of operator IDs or operator names based on the operator management information registered in the operation sequence management means 2g, and filters operators who want to extract operation sequences. To specify.

Since only the transmission / reception of these information and the operation support function are provided, the operation sequence is exchanged between the medical diagnostic apparatus 10 and the management server 20 even when the operation sequence is reproduced.

  First, the operation sequence selection unit 2i performs communication control from the operation sequence information request unit 2m in order to select an operation sequence for which operation support is requested from among the operation sequences recorded in the operation sequence management unit 2g. A request for information on the selected operation sequence is made to the operation sequence management means 2g in the management server 20 via the means 1h and the network 30.

  Next, on the management server 20 side, the operation sequence information response means 2o receives an information request from the medical diagnostic apparatus 10 and inquires the operation sequence management means 2g about the requested operation sequence. The operation sequence information response means 2o receives the corresponding operation sequence from the operation sequence management means 2g and transmits it to the operation sequence information request means 2m. The operation sequence selection means 2i receives the corresponding operation sequence from the operation sequence information request means 2m, and starts operation support in the operation sequence reproduction means 2j.

  In this way, by extracting information necessary for operating the medical diagnostic apparatus from the operation history information and managing it in units of examination work, users and medical diagnostic apparatuses used for low-frequency functions Even if a user who has little experience in using the device forgets to operate the medical diagnostic apparatus, it is possible to improve the operability of the medical diagnostic apparatus by receiving operation support based on the past operation history information. An operation support system and a medical diagnostic apparatus equipped with the system can be provided.

  In particular, as described above, when the management server 20 is connected to a plurality of medical diagnostic apparatuses 10 via the network 30, for example, the operation procedure master storage means exists in the HIS, and the operation procedure master is managed and operated on the HIS. It is possible to instruct the procedure. That is, the operation procedure of all the medical diagnostic apparatuses 10 connected to the network 30 can be managed from one management server, and the operation sequence cooperation for a plurality of medical diagnostic apparatuses 10 is also possible.
