Description

An embodiment of the present invention relates to a medical image diagnostic apparatus and a program.

In recent years, opportunities to utilize information, such as analyzing market trends by analyzing big data, are increasing. For this reason, the value of information is increasing, leading to a situation in which personal information is targeted.

In particular, medical institutions that store detailed personal information are likely to be targeted. As a security measure for medical devices, personal authentication of users using personal accounts and passwords is typical. Recently, from the viewpoint of strengthening security, there is a tendency for security measures to become stricter, such as increasing the length and complexity of passwords, and locking devices in the event of an input error.

On the other hand, since patient safety is given top priority, medical devices may be used without personal authentication in case of emergency. However, when using a medical device without personal authentication, it is common that the functions that can be used are limited. Therefore, the workflow, the feeling of operating the device, the operating method, and the like in an emergency are different from those in normal times, and there is a possibility that the usability may be degraded.

The problem to be solved by the invention is to suppress deterioration of usability while enhancing security.

According to an embodiment, a medical imaging apparatus comprises a definer and a limit controller. The definition unit defines an execution restriction on the condition that a second process for performing an examination is first executed with respect to a first process that handles information about a patient. The restriction control unit cancels the execution restriction imposed on the first process when the condition is satisfied by executing the second process.

(First embodiment)
FIG. 1 is a diagram showing an example of the functional configuration of a medical image diagnostic apparatus 100 according to the first embodiment. A medical image diagnostic apparatus 100 shown in FIG.

The inspection device 121 is a device that acquires patient internal information, and executes various functions of the medical image diagnostic apparatus 100 . Examples of the inspection device 121 include, for example, an X-ray tube and an X-ray detector when the medical image diagnostic device 100 is an X-ray CT (Computed Tomography) device. Further, for example, when the medical image diagnostic apparatus 100 is an ultrasonic image diagnostic apparatus, for example, an ultrasonic probe and an image generating apparatus that generates an ultrasonic image based on a signal acquired via the ultrasonic probe are provided. include. Also, for example, when the medical image diagnostic apparatus 100 is a magnetic resonance imaging (MRI) apparatus, it includes a static magnetic field magnet, a gradient magnetic field coil, and a gradient magnetic field power supply.

The bus 123 is a transmission line through which data is transmitted between the input interface 125 , the display 127 , the communication interface 128 , the memory 129 and the processing circuitry 131 . Various biological signal measuring instruments, external storage devices, and the like may be appropriately connected to the bus 123 via a network or the like.

The input interface 125 receives various instructions and information input by the operator, and outputs the received instructions and information to the processing circuit 131 . The input interface 125 is connected to input devices such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touch pad, and a touch panel for inputting instructions by touching the operation surface. Also, the input device connected to the input interface 125 may be an input device provided in another computer connected via a network or the like.

The display 127 displays various information according to instructions from the processing circuit 131 . Also, the display 127 may display a GUI (Graphical User Interface) or the like for accepting various operations from the user. Any display such as a CRT (Cathode Ray Tube) display, a liquid crystal display, an organic EL display, an LED display, and a plasma display can be used as the display 127 as appropriate.

The communication interface 128 performs data communication with a hospital system via a hospital network such as a LAN (Local Area Network). The communication interface 128 performs data communication, for example, in compliance with a preset known standard. For example, communication with PACS (Picture Archiving and Communication System) is performed in compliance with DICOM (Digital Imaging and Communication Medicine).

The memory 129 is a storage device such as a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), an SSD (Solid State Drive), and an integrated circuit storage device that stores various information. Also, the memory 129 may be a drive device or the like that reads and writes various information from/to a portable storage medium such as a CD-ROM drive, a DVD drive, and a flash memory. Note that the memory 129 does not necessarily have to be realized by a single storage device. For example, memory 129 may be implemented by multiple storage devices. Alternatively, the memory 129 may reside in another computer connected to the medical image diagnostic apparatus 100 via a network.

The memory 129 stores programs corresponding to various functions executed by the processing circuit 131 . Note that programs corresponding to these various functions may be stored in advance in the memory 129, for example. Alternatively, for example, it may be stored in a non-transitory storage medium, distributed, read from the non-transitory storage medium, and installed in the memory 129 .

The medical image diagnostic apparatus 100 according to the present embodiment requests the operator to log on at the start of use, and authenticates the operator based on the user name and password input by the operator. The memory 129 stores user names and passwords set for operators.

In the medical image diagnostic apparatus 100 according to the present embodiment, executable processing is restricted according to user definition under the control of the processing circuit 131 . Then, the medical image diagnostic apparatus 100 makes the restricted processes executable step by step according to the execution status of the processes set to be executable. The memory 129 stores a process whose execution is restricted to the operator and a condition for releasing the restriction. It should be noted that it is possible to change the settings of the process whose execution is restricted to the operator and the conditions for releasing the restriction.

The memory 129 stores data obtained by inspection by the inspection device 121 under the control of the processing circuit 131 . In addition, the medical image diagnostic apparatus 100 according to the present embodiment determines whether an operator whose executable processing is restricted satisfies the conditions for releasing the restriction. must be remembered. Under the control of the processing circuit 131, the memory 129 stores the processing executed according to the operator's instruction together with the execution time.

The processing circuit 131 is a processor that functions as the core of the medical image diagnostic apparatus 100 . The processing circuit 131 implements a function corresponding to the program by executing the program stored in the memory 129 or the like. For example, the processing circuit 131 has a system control function 1311, an authentication/management function 1314, an operation storage function 1315, a gate definition function 1316, and a restriction control function 1317 by executing programs. In this embodiment, the case where the system control function 1311, the authentication/management function 1314, the operation storage function 1315, the gate definition function 1316, and the limit control function 1317 are realized by a single processor will be described. Not limited. For example, a processing circuit is configured by combining a plurality of independent processors, and each processor executes a program to perform system control function 1311, authentication/management function 1314, operation storage function 1315, gate definition function 1316, and limit control function. 1317 may be realized.

The system control function 1311 is a function for overall control of the medical image diagnostic apparatus 100 . Specifically, in the system control function 1311, the processing circuit 131 drives the inspection device 121 based on scanning conditions input by the operator via the input interface 125, for example.

The authentication/management function 1314 is a function of managing logon information and authenticating an operator based on information input by the operator at the time of logon, and is an example of an authentication unit. Specifically, in the authentication/management function 1314, the processing circuit 131 causes the display 127 to display a logon screen and prompts the operator to input information required for logon. The processing circuit 131 collates the user name and password input by the operator with the user name and password stored in the memory 129 to authenticate the operator. If the entered user name and password are the same as the user name and password stored in memory 129, processing circuitry 131 determines that a normal logon has been performed.

Medical devices have the characteristic of giving top priority to patient safety. Therefore, the medical image diagnostic apparatus 100 according to the present embodiment is provided with an emergency logon function that allows the operator to log on without entering a user name and password. For example, an emergency logon button is displayed on the logon screen displayed on the display 127 . When emergency logon is selected by the operator, such as pressing an emergency logon button, the processing circuit 131 authenticates that the operator has logged on as an emergency user.

The operation storage function 1315 is a function for managing executed processing. Specifically, in the operation storage function 1315, the processing circuit 131 stores the executed process in the memory 129 together with the execution time, for example, each time the medical image diagnostic apparatus 100 executes the process according to the operator's instruction. . The processing of the medical image diagnostic apparatus 100 includes, for example, normal logon processing using a user name and password, emergency logon processing as an emergency user, patient information registration processing, scan condition setting processing, and reconstruction condition setting processing. , photographing processing, examination termination processing, image analysis processing, filming processing, image transfer processing, logoff processing, and the like.

The gate definition function 1316 is a function that defines restrictions on processing of the medical image diagnostic apparatus 100, and is an example of a definition section. Specifically, for example, the memory 129 stores processes that can be executed without restrictions. A process that can be executed without restriction is, for example, a process related to an urgently requested examination. Further, for example, the memory 129 stores a process whose execution is restricted together with a condition for releasing the restriction. A process whose execution is restricted is, for example, a process that handles information about a patient. The condition for releasing the restriction is, for example, execution of a process related to an urgently requested examination. In the gate definition function 1316, the processing circuit 131 changes the processing whose execution is restricted and the conditions for canceling the restriction stored in the memory 129, for example, according to the operator's input instruction.

The restriction control function 1317 is a function for activating restrictions set for processing, and is an example of a restriction control unit. Specifically, in the limit control function 1317, the processing circuit 131 activates the limit set for the process upon receiving a predetermined input from the operator. The predetermined input from the operator is, for example, emergency logon as an Emergency User. It should be noted that restrictions set for processing may be activated in response to an input of an instruction to activate the medical image diagnostic apparatus 100 from the operator.

The restriction control function 1317 is also a function for canceling restrictions on processes whose execution is restricted based on the executed processes. Specifically, in the limit control function 1317, for example, when the medical image diagnostic apparatus 100 executes a process and the executed process is stored in the memory 129, the processing circuit 131 controls the executed process stored in the memory 129. Read processing. The processing circuit 131 also reads the conditions for releasing the restriction stored in the memory 129 . The processing circuit 131 compares the executed process with the condition and determines whether the executed process satisfies the condition. If so, processing circuitry 131 releases the restricted processing.

Next, in the medical image diagnostic apparatus 100 configured as described above, the operation of releasing the restrictions set for each process will be described according to the processing procedure of the processing circuit 131. FIG. In the following description, the case where the medical image diagnostic apparatus 100 is an MRI apparatus will be described as an example.

FIG. 2 is a flow chart showing an example of the operation of the processing circuit 131 shown in FIG. 1 executing processing while releasing restrictions. Note that FIG. 2 illustrates an example in which the operator logs on as an emergency user.

First, the operator activates the medical image diagnostic apparatus 100 . When the medical image diagnostic apparatus 100 is started, the logon screen shown in FIG. 3 is displayed on the display 127 . The medical image diagnostic apparatus 100 may display the logon screen shown in FIG. 3 on the display 127 when returning from the standby state.

The operator presses the “Emergency User” button B1 on the log-on screen via the input interface 125 . When the operator presses the “Emergency User” button B 1 , the processing circuit 131 executes the authentication/management function 1314 . When the authentication/management function 1314 is executed, the processing circuit 131 authenticates that the operator has logged on as an emergency user (step S21).

When logging on as a normal user, the operator enters the user name registered in "Name", enters the password associated with the entered user name in "Password", and then presses "Login". ” button B 2 via the input interface 125 .

When the processing circuit 131 determines that the operator has urgently logged on as an Emergency User, the processing circuit 131 executes the operation storage function 1315 . When the operation storage function 1315 is executed, the processing circuit 131 stores in the memory 129 the emergency logon of the operator and the emergency logon time of the operator (step S22).

When an operator logs on as an emergency user, the operator can log on to the device without having a legitimate account. Therefore, in the description of FIG. 2, in order to maintain security, for example, when an operator logs on as an emergency user in an emergency, a predetermined operation of the medical image diagnostic apparatus 100 is restricted. That is, the processing circuit 131 executes the limit control function 1317 when it determines that the operator has logged on as an emergency user in an emergency.

When the restriction control function 1317 is executed, the processing circuit 131 reads the processing stored in the memory 129 whose execution is restricted for the Emergency User. FIG. 4 is a diagram showing an example of a management table stored in memory 129 shown in FIG. The management table shown in FIG. 4 defines processes 1 to 12 executable by the medical image diagnostic apparatus 100 . At least one of the stipulated processes is a low security level process that can be executed immediately after logon as an Emergency User, for example, a process for implementing an emergency inspection. Further, other specified processing is processing with a high security level, for example, processing information about patients, which cannot be executed immediately after logging on as an Emergency User.

Specifically, for example, in FIG. 4, process 1: "emergency logon", process 2: "patient registration", process 3: "scan condition setting", process 4: "reconstruction condition setting", process 5: " Photograph", process 6: "examination end for current examination", and process 12: "log off" are low security level processes that can be executed immediately after logon as an emergency user. Processing 3: "scanning condition setting", processing 4: "reconstruction condition setting", and processing 5: "imaging" are executable only for the current patient who must be examined urgently, for example. Suppose that That is, it is not possible to refer to information other than the examination of the patient currently being handled. Also, with respect to process 3: "scan condition setting" and process 4: "reconstruction condition setting", restrictions may be added to settable parameters.

Process 7: "Image Processing for Currently Acquired MR Image" Process 8: "Filming of Currently Acquired Information" Process 9: "Filming of Previously Acquired Information About This Patient" , Process 10: "Transfer of currently acquired images", and Process 11: "Transfer of previously acquired images of this patient" are processes with a high security level that cannot be performed immediately after logging on as an Emergency User. is. In other words, immediately after logging on as an emergency user, the operator cannot perform image processing, cannot perform image filming, and cannot transmit images to another server. Image processing for MR images includes, for example, Maximum Intensity Projection (MIP) processing for MR image data and MPR (Multi-Planar Reconstruction) processing for MR image data.

At least one of the low security level processes is set as a gate for releasing the restrictions on the high security level processes. In the present embodiment, a gate represents a requirement to be satisfied, for example, as a condition for releasing restrictions on processing with a high security level. Specifically, for example, process 3: "scan condition setting", process 4: "reconstruction condition setting", process 5: "imaging", and process 6: "examination end for current examination" are gates. It is set as 1-4.

In addition, at least one of the high security level processes is set as a gate for releasing the restrictions on the higher security level processes. Specifically, for example, process 7: “image processing for currently acquired MR image” is set as gate 5 .

In FIG. 4, a condition for releasing the restriction is set for a process with a high security level. Specifically, for example, for process 7: "image processing for currently acquired MR image", gates 1-4 are in a predetermined order, e.g., gates 1, 2, 3, 4 It is set as a condition to pass through. Also, for process 8: "Filming of currently acquired information", it is set as a condition that gates 1 to 4 are passed through in a predetermined order. In addition, for process 9: "Filming of information acquired in the past", it is set as a condition that gates 1 to 5 are passed through in a predetermined order. In addition, for process 10: "Transfer of currently acquired image", it is set as a condition that gates 1 to 3 are passed in a predetermined order. In addition, for the process 11: "Transfer of images acquired in the past", it is set as a condition that the gates 1 to 5 are passed in a predetermined order.

The processing circuit 131 refers to the management table shown in FIG. 4 to determine the processing that is restricted to the Emergency User, specifically the processing 7: "image processing for the currently acquired MR image". , Process 8: "Filming currently acquired information", Process 9: "Filming previously acquired information", Process 10: "Transfer currently acquired image", and Process 11: " Transfer of images acquired in the past” is read. The processing circuit 131 is set so as not to accept the execution of these processes (step S23). That is, it activates the restrictions that have been set for the process.

The processing circuit 131 notifies the operator that these processes cannot be performed under the present circumstances. For example, processing circuit 131 displays on display 127 that these processes cannot be performed, as shown in FIG. 5 (step S24). In the example shown in FIG. 5, a dialog is displayed indicating that there are functional restrictions for Emergency User. Further, in FIG. 5, the icon I1 at the lower right of the display 127 is displayed in gray, indicating that information on past examinations cannot be referred to.

Subsequently, the processing circuit 131 determines in the limit control function 1317 whether or not there is a process through which the gate set in the condition is passed (step S25). Here, since the emergency user has just logged on, no gate has been passed through (No in step S25). Therefore, the processing circuit 131 executes currently executable processing according to the instruction from the operator (step S26).

Specifically, for example, the processing circuitry 131 receives an instruction to register patient information from the operator. The processing circuit 131 executes patient information registration processing according to the instruction. FIG. 6 is a diagram showing an example of a patient registration screen. On the registration screen shown in FIG. 6, an inspection list L1 is displayed. In the examination list L1 in FIG. 6, only information about the examination of the patient currently being handled is displayed. Patient information may be registered, for example, based on an urgent test order issued for this patient, or may be registered by an operator via input interface 125 .

The processing circuitry 131 executes the operation storage function 1315 when executing a currently executable process, here a patient registration process. When the operation storage function 1315 is executed, the processing circuit 131 stores in the memory 129 that the operator has registered the patient and the time at which the operator registered the patient (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. Since the only process executed is patient registration, no gate has been passed (No in step S25). Therefore, the processing circuit 131 executes currently executable processing according to the instruction from the operator (step S26).

Specifically, for example, the processing circuitry 131 receives from the operator an instruction to set scan conditions for the examinations displayed in the examination list L1. The processing circuit 131 executes a scan condition setting process for the selected examination in accordance with the instruction. FIG. 7 is a diagram showing an example of a scan condition setting screen. On the setting screen shown in FIG. 7, the parameters for the examination of the patient currently being handled are entered. Values for the parameters to be entered may be entered automatically based on, for example, an urgent test order issued for this patient, or may be entered by an operator via input interface 125 .

When the processing circuit 131 executes the currently executable processing, here, the scan condition setting processing, it stores in the memory 129 that the operator has set the scan conditions and the time at which the operator has set the scan conditions (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. Since the scan condition setting process has been executed, gate 1 has been passed, but the condition for releasing the restriction has not yet been satisfied (No in step S25). Therefore, the processing circuit 131 executes currently executable processing according to the instruction from the operator (step S26).

Specifically, for example, the processing circuitry 131 receives from the operator an instruction to set a reconstruction condition for an examination for which setting of the scan condition has been completed. The processing circuit 131 executes a reconstruction condition setting process according to the instruction. In the reconstruction condition setting process, the reconstruction conditions for the examination of the patient currently being handled are input. Reconfiguration conditions may be entered automatically based on, for example, an urgent test order issued for this patient, or may be entered by an operator via input interface 125 .

When the processing circuit 131 executes currently executable processing, here processing for setting reconstruction conditions, the processing circuit 131 stores in the memory 129 the fact that the operator has set the reconstruction conditions and the time at which the operator has set the reconstruction conditions. (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. According to the process stored in the memory 129 and the time when this process was executed, the scan condition setting process was executed and then the reconstruction condition setting process was executed. are passed in the order of However, the conditions for releasing the restriction have not yet been met (No in step S25). Therefore, the processing circuit 131 executes currently executable processing according to the instruction from the operator (step S26). Specifically, for example, the processing circuit 131 receives an imaging instruction from the operator for an examination for which the setting of reconstruction conditions has been completed. The processing circuit 131 performs imaging of the patient according to the instruction.

The processing circuit 131 stores in the memory 129 the currently executable processing, here, when imaging of the patient is completed, the fact that the imaging of the patient has been completed and the time when the imaging of the patient has been completed (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. According to the process stored in the memory 129 and the time at which this process was executed, the scan condition setting process was executed, and the reconstruction condition setting process was executed, and then the imaging of the patient was executed. The gates are passed in the order gate 1, gate 2, gate 3. According to FIG. 4, the condition for releasing the restriction for process 10: "transfer of currently acquired information" is that gates 1 to 3 are passed in a predetermined order. The processing circuit 131 determines that the condition for releasing the restriction on the processing 10 is satisfied (Yes in step S25).

When determining that the condition for removing the restriction on process 10 is satisfied, processing circuit 131 releases a part of the restriction on process 10, that is, the restriction on process 10 (step S29). When part of the restriction on processing is released, processing circuit 131 causes display 127 to display that the restriction has been released (step S210). FIG. 8 is a diagram showing an example of a dialog displayed on display 127 when transfer of currently acquired information becomes executable.

Subsequently, the processing circuit 131 executes a currently executable process according to an instruction from the operator (step S26). Here, for example, process 3: "scan condition setting", process 4 "reconstruction condition setting", process 5: "imaging", process 6: "examination end for current examination", or process 10: "current acquisition A case will be described where the operator instructs execution of process 6: "end of current examination" although "Transfer of current image" can be executed.

When the imaging of the patient is completed, the processing circuit 131 executes the end processing of the current examination according to the instruction from the operator. FIG. 9 is a diagram showing an example of an inspection end screen. On the end screen shown in FIG. 9, a check mark C1 is added to the examination for which imaging has been completed. Also, on the end screen shown in FIG. 9, an icon I2 representing "examination end" is displayed for instructing the end of the examination. When the operator presses the icon I2 via the input interface 125, this inspection ends.

When the processing circuit 131 executes the currently executable processing, here, the end processing of the inspection, the processing circuit 131 stores in the memory 129 the completion of the inspection and the time at which the inspection was completed (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. According to the process stored in the memory 129 and the time when this process was executed, the scan condition setting process is executed, the reconstruction condition setting process is executed, and the patient is photographed. is terminated, the gates are passed in the order gate 1, gate 2, gate 3, gate 4. According to FIG. 4, the conditions for releasing the restrictions on process 7: "image processing of the MR image currently being acquired" and process 8: "filming of information currently being acquired" are that gates 1 to 4 are It is to be passed through in a given order. The processing circuit 131 determines that the conditions for releasing the restrictions on the processes 7 and 8 are satisfied (Yes in step S25).

When it is determined that the conditions for releasing the restrictions on the processes 7 and 8 are satisfied, the processing circuitry 131 releases part of the restrictions on the processes, that is, the restrictions on the processes 7 and 8 (step S29). When part of the restriction on processing is released, processing circuit 131 causes display 127 to display that the restriction has been released (step S210). FIG. 10 is a diagram showing an example of a dialog displayed on the display 127 when image processing for an MR image and filming of currently acquired information can be executed.

Subsequently, the processing circuit 131 executes a currently executable process according to an instruction from the operator (step S26). Here, for example, Process 9: "Filming of previously acquired information about this patient" and Process 11: Processes other than "Transfer of previously acquired information about this patient", that is, Process 3 : "scan condition setting", process 4: "reconstruction condition setting", process 5: "imaging", process 7: "image processing for currently acquired MR image", process 8: "currently acquired filming of information", and process 10: "transfer of currently acquired images" can be executed, but the operator cannot execute process 7: "image processing on currently acquired MR images". I will explain when it is instructed.

Upon completion of the examination, the processing circuit 131 executes image processing on the MR image obtained for the current patient in accordance with instructions from the operator. The processing circuit 131 creates, for example, an MIP image or an MPR image by executing image processing on the MR image.

When the processing circuit 131 executes currently executable processing, here image processing for an MR image, the processing circuit 131 stores in the memory 129 the fact that the image processing was executed and the time at which the image processing was executed (step S27).

The processing circuit 131 determines in step S25 through the processing in step S28 whether or not there is any processing that has passed through the gate set by the conditions. According to the process stored in the memory 129 and the time when this process was executed, the scan condition setting process is executed, the reconstruction condition setting process is executed, the patient is imaged, and the examination is completed. After that, the gates are passed through in the order of gate 1, gate 2, gate 3, gate 4, and gate 5 because the image processing for the MR image has been performed. According to FIG. 4, the conditions for releasing the restrictions on process 9: "Filming of previously acquired information about this patient" and Process 11: "Transfer of previously acquired images about this patient" are: Gates 1-5 are passed through in a predetermined order. The processing circuit 131 determines that the conditions for releasing the restrictions on the processes 9 and 11 are satisfied (Yes in step S25).

When it is determined that the conditions for releasing the restrictions on the processes 9 and 11 are satisfied, the processing circuitry 131 releases part of the restrictions on the processes, that is, the restrictions on the processes 9 and 11 (step S29). When part of the restriction on processing is released, processing circuit 131 causes display 127 to display that the restriction has been released (step S210). FIG. 11 shows an example of a dialog displayed on display 127 when filming and forwarding of previously obtained information about this patient is enabled.

FIG. 12 is a diagram showing an example of a patient registration screen when restrictions on processing are lifted and examinations performed on this patient in the past can be referred to. According to FIG. 12, the examination list L1 includes not only the currently acquired information but also the information acquired in the past regarding a patient for whom an urgent examination request has been received.

Subsequently, in step S28, the processing circuit 131 determines whether or not the operator has performed logoff processing. If the logoff process has been performed (Yes in step S28), the processing circuit 131 resets the process execution record stored in the memory 129 (step S211), and terminates the process.

Note that the display on the display 127 when logged on as an Emergency User is not limited to the displays shown in FIGS. For example, the display 127 may display an icon I3 indicating that the operator has logged on as an emergency user. FIG. 13 is a diagram showing an example in which the icon I3 is represented as "Emergency Mode" and displayed on the right end of the patient registration screen. This icon I3 allows the operator to proceed with the process while recognizing that he/she has logged on as an emergency user.

Further, when the operator presses the icon I3, for example, the logon screen shown in FIG. 3 may be displayed. As a result, it is possible to switch to normal logon at any time, and the processing of the medical image diagnostic apparatus 100 can be executed without restriction.

Further, the display 127 may display currently executable processing. FIG. 14 is a schematic diagram showing an example of a patient registration screen displaying currently executable processes. According to FIG. 14, the processes that can be executed at this time are displayed brightly, and the restricted processes are shaded.

Further, the processing set for the medical image diagnostic apparatus 100 is not limited to that shown in FIG. The operator can change the settings shown in FIG. Upon receiving an instruction from the operator to change the setting of the restriction, the processing circuit 131 executes the gate definition function 1316, for example. In the gate definition function 1316, the processing circuit 131 sets restrictions imposed on processing and conditions for canceling the restrictions based on instructions from the operator.

FIG. 15 is a diagram showing an example of a setting screen for processing restrictions. According to FIG. 15, 'target', 'gate (release condition)', and 'emergency user' are associated with 'process'. The processing circuit 131 may add a new process to the "process" and/or delete any process from the "process" based on the input from the operator. In addition, the processing circuit 131, based on the input from the operator, to the "object", for example, "-", "current patient", "past patient", "current examination", and "past examination" You may set any one of etc. Further, the processing circuit 131 may check or delete any of the check boxes displayed in the "gate (release condition)" based on the input from the operator. Further, the processing circuit 131 may check or delete any of the check boxes displayed in "Emergency User" based on the input from the operator. Note that there may be some processing that cannot be executed by logging on as an Emergency User.

Also, in the description relating to FIG. 2, the case where the restriction on processing is started when the operator logs on as an emergency user has been described. However, the start of the restriction on processing is not limited to being triggered by logging on as an Emergency User. For example, after the medical image diagnostic apparatus 100 is activated, if it becomes usable without going through the logon screen, the processing circuit 131 may execute the restriction control function 1317 in response to the activation of the medical image diagnostic apparatus 100. do not have. In this case, processing restrictions are imposed on all operators regardless of the urgency of the examination.

As described above, in the first embodiment, the medical image diagnostic apparatus 100 imposes a restriction on the process of handling patient information on the condition that the process for performing an examination is executed first. there is Then, the medical image diagnostic apparatus 100 makes it possible to execute the restricted process of handling information about the patient when the condition is satisfied by the operator executing the process for performing the examination. I'm trying As a result, the restriction on the process of handling information about the patient, which was imposed when the operation was started, is eliminated by following the predetermined procedure. Therefore, even if an unauthorized user pretending to be an operator uses the medical image diagnostic apparatus 100, the patient information cannot be freely handled at the beginning of use. On the other hand, if a predetermined procedure is followed, the processing of the medical image diagnostic apparatus 100 can be executed without inconvenience.

Further, according to the present embodiment, logon is not essential for using the medical image diagnostic apparatus 100 . This eliminates the need to enter a user name and password, which eliminates the problem of forgetting to issue a personal account, or forgetting or losing a user name and/or password.

Furthermore, according to this embodiment, it is possible to improve the security of the medical image diagnostic apparatus 100 without using biometric authentication or the like. Therefore, no additional device is required, and an increase in the cost of the apparatus can be prevented. In addition, advance preparation for using biometrics authentication is unnecessary.

In addition, in the first embodiment, the medical image diagnostic apparatus 100 executes processing for performing an emergency examination before processing for handling patient information when an operator logs on for emergency. is subject to restrictions. Then, when the condition is satisfied by the operator executing a process for performing an urgent examination, the medical image diagnostic apparatus 100 executes the restricted process of handling information about the patient. I am trying to make it possible. This makes it possible to protect the patient's information while allowing the operator to perform an urgent examination. In addition, since the restricted processing is released after the inspection is appropriately performed, it is possible to bring the workflow, the operational feel of the device, and the operational method closer to normal times.

In addition, in the first embodiment, the medical image diagnostic apparatus 100 cancels restrictions placed on processing based on the order of the executed processing. In other words, the restrictions are lifted only when the medical image diagnostic apparatus 100 is operated in compliance with the examination workflow. This makes it possible to further improve the security of processing that handles patient information.

Note that in the first embodiment, an example has been described in which restrictions imposed on processes are lifted based on the executed processes, the executed processes, and their execution order. The decision to remove the restrictions imposed on the processes is not limited to those based on the executed processes, and the executed processes and their execution order.

For example, the processing circuit 131 may not release processing that requires the execution of the imaging process when the imaging process is not normally executed. Specifically, for example, the processing circuit 131 does not release the processing that requires the execution of the photographing processing when a plausible image cannot be obtained by photographing. At this time, the processing circuit 131 has, for example, an image recognition function and a determination function by executing a program stored in the memory 129 or the like. The image recognition function is a function of executing image recognition processing on an image acquired by photographing. The processing circuit 131 executes an image recognition function, for example, when imaging is completed and medical image data is generated. In the image recognition function, the processing circuit 131 executes image recognition processing on medical image data using, for example, existing image recognition technology.

The judgment function is a function for judging whether or not an image obtained by photographing is plausible. For example, the processing circuit 131 executes the determination function when the image included in the medical image data is recognized by the image recognition function. In the determination function, the processing circuit 131 determines whether or not the image obtained by imaging is plausible, for example, by comparing the recognized image with preset model data for each part.

The processing circuitry 131 executes the restriction control function 1317, for example, when the imaging process of the patient in step S26 is completed. In the restriction control function 1317, the processing circuit 131 determines that the image capturing process has not been executed when the determining function determines that the captured image is not likely. That is, processing circuit 131 determines that Gate 3 has not been passed.

Further, for example, if an interpretation report for a medical image obtained by imaging is not created, the processing circuit 131 assumes that the imaging process has not been performed normally, and does not release the process that requires execution of the imaging process. good too. At this time, the processing circuit 131 has, for example, a report confirmation function by executing a program stored in the memory 129 or the like.

The report confirmation function is a function for confirming whether or not an interpretation report for a medical image obtained by imaging has been created. The processing circuit 131 executes a report confirmation function, for example, when imaging is completed and the obtained medical image data is transferred to the PACS server. In the report confirmation function, processing circuitry 131, for example, monitors the report system to confirm whether an interpretation report has been generated.

The processing circuitry 131 executes the restriction control function 1317, for example, when the imaging process of the patient in step S26 is completed. In the restriction control function 1317, the processing circuit 131 determines that the imaging process has not been executed when the result of confirmation that the interpretation report has been created is not obtained by the report confirmation function. That is, processing circuit 131 determines that Gate 3 has not been passed.

In addition, for example, when the approval of the medical image obtained by imaging is not obtained from the other party, the processing circuit 131 determines that the imaging process is not normally executed, and releases the process requiring the execution of the imaging process. You can choose not to. At this time, the processing circuit 131 has, for example, a consent confirmation function by executing a program stored in the memory 129 or the like.

The consent confirmation function is a function for confirming whether or not the other person has consented to the medical image obtained by imaging. The processing circuit 131 executes a consent confirmation function, for example, when imaging is completed and the obtained medical image data is transferred to the PACS server. In the consent confirmation function, the processing circuit 131 monitors the PACS, for example, and confirms whether or not consent has been obtained from the other party.

The processing circuitry 131 executes the restriction control function 1317, for example, when the imaging process of the patient in step S26 is completed. In the restriction control function 1317, the processing circuit 131 determines that the photographing process has not been executed when the consent confirmation function does not obtain a confirmation result that consent has been obtained from the other person. That is, processing circuit 131 determines that Gate 3 has not been passed.

Further, for example, the processing circuit 131 may not release the processing for handling information about the patient when the patient is not present on the bed on which the patient should be placed during the examination. Specifically, for example, the processing circuit 131 has a patient confirmation function by executing a program stored in the memory 129 or the like.

The patient confirmation function is a function for confirming whether or not there is a patient on the bed. The processing circuit 131 executes a patient confirmation function when, for example, scan condition setting processing, reconstruction condition setting processing, or patient imaging processing is started. In the patient confirmation function, the processing circuitry 131 confirms the presence of the patient on the bed, for example, by sensing the weight of the bed. Processing circuitry 131 determines that there is no patient on the couch if the sensed weight is less than the specified value.

For example, the processing circuit 131 executes the restriction control function 1317 when executing the scanning condition setting process, the reconstruction condition setting process, and the patient imaging process in step S26. In the restriction control function 1317, the processing circuit 131 determines that the above process has not been executed when the patient confirmation function has confirmed that there is no patient on the bed. That is, the processing circuit 131 determines that the gates 1 to 3 corresponding to each process have not been passed.

Further, for example, the processing circuit 131 may not release the processing that requires the execution of the scan condition setting processing when the scan conditions are not correct. Specifically, for example, the processing circuit 131 has a scan condition determination function by executing a program stored in the memory 129 or the like.

The scan condition determination function is a function for determining whether or not the set scan conditions are correct. For example, the processing circuit 131 executes a scan condition determination function when scan conditions are set. In the scan condition determination function, the processing circuit 131 determines whether or not the set scan conditions are correct, for example, by comparing the set scan conditions with the preset scan conditions.

The processing circuit 131 executes the limit control function 1317, for example, when the scan condition setting process in step S26 is completed. In the limit control function 1317, the processing circuit 131 determines that the scan condition setting process has not been executed when the scan condition determination function has determined that the set scan conditions are not correct. That is, processing circuit 131 determines that gate 1 has not been passed.

Further, for example, the processing circuitry 131 may not release the processing that requires the execution of the end processing of the examination when the examination is not appropriate. Specifically, for example, if the inspection result does not match the inspection order, the processing circuitry 131 does not release the process requiring execution of the inspection end process. At this time, the processing circuit 131 has, for example, an inspection determination function by executing a program stored in the memory 129 or the like.

The inspection determination function is a function for determining whether or not the inspection result matches the information included in the inspection order. The processing circuit 131 executes an inspection determination function, for example, when the inspection is completed. In the inspection determination function, the processing circuit 131 determines, for example, whether or not the inspection result matches the information included in the inspection order, such as scan conditions, parts, body positions, film types, and the like.

The processing circuit 131 executes the limit control function 1317, for example, when the end processing of the inspection in step S26 is completed. In the restriction control function 1317, the processing circuit 131 determines that the inspection end processing has not been executed when the inspection determination function obtains a determination result that the inspection result and the inspection order do not match. That is, the processing circuit 131 determines that Gate 4 has not been passed.

Further, for example, if the inspection is not completed within a predetermined time, the processing circuit 131 may determine that the inspection is not appropriate and may not release the process requiring execution of the inspection completion process. At this time, the processing circuit 131 has, for example, an inspection time determination function by executing a program stored in the memory 129 or the like.

The inspection time determination function is a function for determining whether or not the time taken from the start of the inspection to the end of the inspection is within a predetermined period of time. The processing circuit 131 starts counting the examination time, for example, when patient information is registered. Then, the processing circuit 131 executes an inspection time determination function, for example, when the inspection ends. In the inspection time determination function, the processing circuit 131, for example, stops counting the inspection time and determines whether or not the obtained count value is less than the preset time.

The processing circuit 131 executes the limit control function 1317, for example, when the end processing of the inspection in step S26 is completed. In the limit control function 1317, the processing circuit 131 detects that the count value obtained by the inspection time determination function is equal to or longer than the preset time, the inspection end processing is not being executed. I judge. That is, the processing circuit 131 determines that Gate 4 has not been passed.

(Other examples)
In the description of the operation using FIG. 2, the case where the medical image diagnostic apparatus 100 is an MRI apparatus has been described as an example. However, the medical image diagnostic apparatus 100 is not limited to an MRI apparatus. The medical image diagnostic apparatus 100 can be assumed to be various apparatuses other than an MRI apparatus, such as an X-ray diagnostic apparatus, an X-ray CT (Computed Tomography) apparatus, and an ultrasonic diagnostic apparatus.

As for the X-ray diagnostic apparatus, the removal process of the cassette (FPD: Flat Panel Detector) may be restricted to require the execution of other processes. Further, with respect to the ultrasonic diagnostic apparatus, the ultrasonic probe removal process may be restricted to require execution of other processes.

(Second embodiment)
In the first embodiment, the medical image diagnostic apparatus 100 that acquires medical images has been described. In the second embodiment, a case will be described in which the medical image diagnostic apparatus 100a is a report server provided in a report system.

FIG. 16 is a diagram showing an example of the functional configuration of a report system provided with the medical image diagnostic apparatus 100a according to the second embodiment. The report system shown in FIG. 16 is a system for managing interpretation report creation by an interpretation doctor. The report system has, for example, a medical image diagnostic apparatus 100a as a report server and a communication terminal 200. FIG.

The medical image diagnostic apparatus 100a manages various information for an interpretation doctor to create an interpretation report. Specifically, for example, the medical image diagnostic apparatus 100a manages whether or not an interpretation report has been created for an interpretation order using a management list. When the medical image diagnostic apparatus 100a receives the interpretation order information and the patient information transmitted from the HIS (Hospital Information System), for example, one uninterpreted interpretation order is added to the management list.

The communication terminal 200 is, for example, a terminal, such as a viewer, for medical staff such as radiologists to access systems and devices connected to the LAN. Specifically, for example, the communication terminal 200 is operated by an interpreting doctor and creates an interpretation report based on information provided from the medical image diagnostic apparatus 100a.

A medical image diagnostic apparatus 100a shown in FIG. 16 includes a bus 123, an input interface 125, a display 127, a communication interface 128, a memory 129a, and a processing circuit 131a.

The memory 129a is a storage device such as ROM, RAM, HDD, SSD, and integrated circuit storage device that stores various information. Also, the memory 129a may be a drive device or the like that reads and writes various information from/to a portable storage medium such as a CD-ROM drive, a DVD drive, and a flash memory. Note that the memory 129a is not limited to a single storage device, and may be realized by a plurality of storage devices, for example. Alternatively, the memory 129a may reside in another computer connected to the medical image diagnostic apparatus 100a via a network.

The memory 129a stores programs corresponding to various functions executed by the processing circuit 131a. Note that programs corresponding to these various functions may be stored in advance in the memory 129a, for example. Alternatively, for example, it may be stored in a non-transitory storage medium and distributed, read from the non-transitory storage medium and installed in the memory 129a. In addition, the memory 129a stores a management list for managing whether or not an interpretation report has been created for an interpretation order.

The medical image diagnostic apparatus 100a according to the present embodiment requests the interpreting doctor to log on when starting to create an interpretation report, and authenticates the interpreting doctor based on the user name and password input by the interpreting doctor. The memory 129a stores user names and passwords set for radiologists.

In this embodiment, the medical image diagnostic apparatus 100a imposes user-defined restrictions on the use of the apparatus by radiologists. Then, the medical image diagnostic apparatus 100a makes the restricted processes executable step by step according to the execution status of the processes set to be executable. The memory 129a stores processing that is restricted to execution by radiologists and conditions for releasing the restriction. It is possible to change the settings of the processing that is restricted to execution by the radiologist and the conditions for releasing the restriction.

The memory 129a stores the interpretation report created by the interpretation doctor under the control of the processing circuit 131a. Further, the medical image diagnostic apparatus 100a according to the present embodiment stores the processing performed by the interpreting doctor to determine whether or not the interpreting doctor whose use is restricted satisfies the conditions for releasing the restriction. There is a need. Under the control of the processing circuit 131a, the memory 129a stores the processing executed according to the instruction of the radiologist along with the execution time.

The processing circuit 131a is a processor that functions as the core of the medical image diagnostic apparatus 100a. The processing circuit 131a realizes a function corresponding to the program by executing the program stored in the memory 129a or the like. For example, the processing circuit 131a has an authentication/management function 1314a, an operation storage function 1315a, a gate definition function 1316a, and a restriction control function 1317a by executing programs. In this embodiment, the case where the authentication/management function 1314a, the operation storage function 1315a, the gate definition function 1316a, and the restriction control function 1317a are realized by a single processor will be described, but the present invention is not limited to this. For example, a processing circuit is configured by combining a plurality of independent processors, and each processor executes a program to realize an authentication/management function 1314a, an operation storage function 1315a, a gate definition function 1316a, and a restriction control function 1317a. I don't mind.

The authentication/management function 1314a is a function for managing logon information and authenticating an interpreting doctor based on information input by the interpreting doctor at the time of logon. Specifically, in the authentication/management function 1314a, the processing circuit 131a causes the display 127 to display a logon screen and prompts the radiologist to input information required for logon. The processing circuit 131a checks the user name and password input by the interpreting doctor against the user name and password stored in the memory 129a to authenticate the interpreting doctor. If the entered user name and password are the same as the user name and password stored in memory 129, processing circuit 131a determines that normal logon has been performed. The logon screen displayed on the display 127 also displays, for example, an emergency logon button. When emergency logon is selected by the interpreting doctor, for example, by pressing an emergency logon button, the processing circuit 131a determines that the interpreting doctor has logged on urgently as an emergency user.

The operation storage function 1315a is a function for managing executed processing. Specifically, in the operation storage function 1315a, the processing circuit 131a stores the executed processing in the memory 129 together with the time of execution each time the interpretation doctor executes a predetermined processing according to the procedure for creating the interpretation report. do. The processing executed by the interpretation doctor includes, for example, registration of patient information, reading of key images, creation of findings, attachment of key images, completion of interpretation reports, and the like.

The gate definition function 1316a is a function that defines restricted usage for radiologists. Specifically, for example, the memory 129a stores processes that can be executed without restrictions. Processing that can be executed without restriction is, for example, processing related to interpretation requested urgently. Further, for example, the memory 129a stores a process whose execution is restricted together with a condition for releasing the restriction. The processes whose execution is restricted are, for example, "filming of information currently requested for interpretation", "filming of information about this patient acquired in the past", "currently "Transfer of images for which radiological interpretation is requested" and "Transfer of images of this patient acquired in the past". The condition for canceling the restriction is, for example, execution of urgently requested processing related to image interpretation. In the gate definition function 1316a, the processing circuit 131a changes the processing whose execution is restricted and the conditions for canceling the restriction stored in the memory 129a, for example, according to the operator's input instruction.

The restriction control function 1317a is a function for activating restrictions set for processing. Specifically, in the limit control function 1317a, the processing circuit 131a activates the limit set for the process upon receiving a predetermined input from the radiologist. The predetermined input from the radiologist is, for example, emergency logon as an Emergency User. Restrictions set for processing may be activated in response to an input of an instruction to activate the medical image diagnostic apparatus 100a from an interpreting doctor.

Further, the restriction control function 1317a is also a function of canceling restrictions on processes whose execution is restricted based on the executed processes. Specifically, in the restriction control function 1317a, the processing circuit 131a reads out the executed processing stored in the memory 129a when, for example, the radiologist executes processing and the executed processing is stored in the memory 129a. . In addition, the processing circuit 131a reads the conditions for releasing the restriction stored in the memory 129a. The processing circuit 131a compares the executed process with the condition and determines whether the executed process satisfies the condition. If so, the processing circuitry 131a releases the restricted processing.

The processing circuit 131a of the medical image diagnostic apparatus 100a releases the processing restricted to the radiologist by the same operation as the flowchart shown in FIG.

As described above, in the second embodiment, the medical image diagnostic apparatus 100a imposes a restriction on the process of handling patient information on the condition that the process for creating an interpretation report is executed first. ing. The medical image diagnostic apparatus 100a can execute the restricted process of handling information about the patient when the condition is satisfied by the execution of the process for creating the interpretation report by the interpreting doctor. I am trying to As a result, the restriction on the process of handling information about the patient, which was placed at the start of creating the interpretation report, can be eliminated by following a predetermined procedure. Therefore, even if an unauthorized user pretending to be an interpreting doctor accesses the medical image diagnostic apparatus 100a from the communication terminal 200, the patient information cannot be handled freely at the start of creation. On the other hand, if a predetermined procedure is followed, the medical image diagnostic apparatus 100a can be used without inconvenience.

In the second embodiment, the medical image diagnostic apparatus 100a as a report server has an authentication/management function 1314a, an operation storage function 1315a, a gate definition function 1316a, and a restriction control function 1317a. However, it is not limited to this. At least one of the authentication/management function 1314a, the operation storage function 1315a, the gate definition function 1316a, and the restriction control function 1317a may be included in the communication terminal 200, which is the viewer.

According to at least one of the embodiments described above, the medical image diagnostic apparatus can suppress deterioration in usability while enhancing security.
