2. Description of the Related Art The inside of a subject is acquired as an image,
Various medical image diagnostic apparatuses capable of performing medical diagnosis based on this image are in widespread use in hospitals of a considerable scale or larger, and they are no longer part of daily diagnostic work. Has become.

As such a medical image diagnostic apparatus, for example, an X-ray is radiated on a subject, and the X-ray is absorbed by organs, bones, etc. in the subject's body to be imaged. An X-ray imaging apparatus for performing X-ray imaging or acquiring the tomographic image of the subject by collecting and reconstructing projection data obtained as a result of irradiating X-rays from multiple directions using the same principle. A line CT apparatus, a magnetic resonance imaging (MRI) apparatus, or the like is generally used, and is generally called a multi-modality.

By the way, when using such various medical image diagnostic apparatuses, for example, an X-ray imaging apparatus, it is necessary to set parameters such as X-ray imaging conditions optimally and perform imaging, and the situation such as light and dark. No good captured image can be obtained, and some skill is required to set the parameters.

Therefore, in order to improve the imaging and operation techniques, it is essential to have an experience of actually irradiating a subject with X-rays and observing the results, and a new engineer who handles radiation such as X-rays is required. When training (radiation technicians), etc., X-ray imaging training is performed by actually irradiating X-rays using a phantom such as a cylinder filled with water or an acrylic body simulating an arbitrary human body shape. Was being done.

Further, not only in the X-ray imaging apparatus but also in other various kinds of medical image diagnostic apparatus (modality), one person monopolizes one actual machine to perform operations by the actual medical image diagnostic apparatus (modality). I was doing a test.

[0008]

However, in the conventional training using the actual machine, since the phantom is used for X-ray imaging training, there is no phantom suitable for various physiques and parts like an actual patient. There is a limit to the amount, and moreover, since the phantom itself is expensive, it is not possible to try with a wide variety. For this reason, it was likely that there would be a large difference in conditions between training and actual clinical settings.

Further, in an apparatus using X-rays, in order to understand how a photographed image changes when a parameter is changed, it is necessary to actually perform bombardment. Extra radiation has been generated to guide the appropriate X-ray conditions under the conditions.

In addition, although an X-ray imaging simulator for simulating X-ray imaging is also provided, the X-ray imaging simulator requires a high-level arithmetic processing device,
Since the arithmetic processing unit is generally expensive, it is difficult to purchase it. In such a case, one person is actually used for each actual machine.

Further, in order to carry out operation training, each actual medical image diagnostic apparatus (actual machine) must be used, so that a person who conducts training such as operation needs a dedicated room in which the medical image diagnostic apparatus is installed. Had to move to. In addition, it is difficult to use the normal business hours of a hospital, for example, to perform operations and tests using an actual machine, and the number of the actual machines is limited, and especially radiation such as X-rays is used. With the device
There are many restrictions such as where it is used, usage conditions, and irradiation dose.
It was not always easy to operate or test.

Further, as described above, in the medical image diagnostic apparatus, it is difficult to predict the result of parameter setting, and the medical image diagnostic apparatus installed in various hospitals may have different models. Since the setting of parameters is different, the device user does not know how to set the parameter, and the device user can make optimal settings other than gaining experience with actual equipment over time. could not.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a user without purchasing an expensive arithmetic unit and without actually performing exposure.

Another object of the present invention is to provide a simulation method and a modality simulator for a medical image diagnostic apparatus capable of performing operations, tests, training of technicians, etc. anytime, anywhere without using each medical image diagnostic apparatus (actual machine). To provide a system.

Further, another object of the present invention is to set the parameters of each medical image diagnostic apparatus without experience with an actual machine, and it is difficult to set the parameters due to differences in hospitals and models. An object of the present invention is to provide an information processing service method capable of solving the above problem.

Information regarding success or failure of whether or not the operation has been performed under various conditions, use history information of these, and the like are stored correspondingly.

The human body model database (human body model information storage means) 30 shows the spatial relationship of the human body structure (human body model) averaged on the basis of the data of sex, age, height, and weight by the X-ray absorption coefficient. The spatial relationship of the human body structure (human body model) averaged based on the data group described by the absorption rate distribution or the data of sex, age, height, and weight is calculated as X.
It includes the data group described by X-ray attenuation rate distribution by the line attenuation coefficient. The spatial relationship of the human body model is a group of data that can be expanded, reduced, rotated, translated, or twisted by calculation based on the parameter values input by the user.

Further, the human body model database 30 has X
It is a data group in which the spatial relationship of the three-dimensional human body structure obtained from the X-ray CT apparatus is described by the X-ray attenuation coefficient or the X-ray absorption coefficient, and the data used in the past can be saved to the user (user). It can be reused at the request of.

As the human body model, it is preferable to use a mathematical four-dimensional (4D) (that is, three-dimensional space and one-dimensional time) model in the imaging simulation. The model is a mathematical basis field (Basis Objec).
t), and each basis field is defined by a mathematical function. Each basis set has a spatial relationship to another basis set, and the basis sets and spatial relationships define the three-dimensional geometric shape of the model. The model can also model other dynamic structures, other anatomical structures, in living and inanimate bodies. Here, for example, the chest (ie, the rib cage of the human body) is modeled as a solid elliptic cylinder, and the ribs are modeled as hollow elliptical cylinders that are tilted to properly model the anatomy of the human body, The lung is modeled as a solid elliptic cylinder, and the heart is modeled by four prolate spheroids and four oblate spheroids.

The model can be transformed by one or more transformation operators (operators that move, scale, or rotate the basis function), and each transformation operator has a predetermined transformation. It corresponds to the conversion operation. If one of the transformation operators acts on one of the basis fields,
The spatial relationship between the affected basis and at least one other basis can change to change the model's geometric shape and impart motion to the model.

When the basis bodies that make up the model are transformed by scaling, translation, rotation and / or twist, each basis body is defined for each time point. Such a basis function that mathematically defines the structure of the model is used to form a three-dimensional mathematical model, and motion can be applied to the three-dimensional model to form a four-dimensional model.

The model of the structure constituting each part of the human body is mathematically defined by the analytical basis body and / or the polygonal basis body. When the structure of the model is described using the basis body, the model can be formed by software by using a class hierarchical data structure that can be written in the C ++ programming language, for example.

Most of the models are composed of analytic basis functions analytically defining basis functions (basis fields that can be mathematically defined by equations), but define the structure in the model to which twist is applied. To do this, a polygon basis function {polygon basis set: basis set mathematically defined as a polygon (closed plane figure defined by three or more edges)} is used.

The modeling process declares a basis field to be used to define the object and sets the linear attenuation coefficient associated with the object to a predetermined value. At this time, the priority value associated with the basis body of the object is set to an appropriate value. The basis value of the basis set is used to determine which of the linear attenuation factors of the intersection region of the basis set should be selected for the ray. In general, the crossing time interval (ie the length of time the ray is inside the basis field)
And the linear attenuation coefficient of the basis body having the highest priority value is selected if the basis bodies have overlapping crossing time intervals.

In addition, the spatial relationship between the basis bodies constituting the object is defined. In addition, the time of interest (eg,
Makes it possible to take advantage of temporal changes in the geometry of the object over the entire heart cycle. In addition, a motion configuration is defined that describes the motion of the object during the time of interest.

At this time, the time instant at which the geometric transformation of the basis body occurs is defined, and the change in the geometrical shape occurring in each basis body at each sampling time is defined. These geometric changes include scaling, translation, rotation, and twist. Then, by generating a similar motion vector for each basis, the object can be moved as a continuous object.

The position of each basis body of the model at each sampling time with reference to the original orientation of the object,
While performing the task of updating the temporal change of the object at the time, a crossing section of the simulated ray is determined for each basis body of the model.

The priority value of each basis set is used to select the linear attenuation coefficient associated with the object having the highest priority value in the intersection interval, and the linear attenuation coefficient of the intersection interval is selected. Perform line integration. Each intersection is processed this way until the ray exits the model. Based on these line integrals, the model image is reconstructed.

The projection data formed using the model is
It corresponds to the integral of the linear attenuation coefficient along the ray associated with the structure that makes up the object model. Then, the projection data is modified in consideration of the physical configuration of the components of the CT system. The processed projection data is then back projected to form a reconstructed CT image of the object. At this time, a motion operator is applied to the object model, and the object model changes its geometric shape as a function of time. It should be noted that the image analysis of the model can also identify the optimal set of operating parameters required for a particular CT imaging.

The image pickup simulator 40 includes an image pickup calculation processing means 41 for performing image pickup calculation processing from the received parameters,
The calculation result notifying unit 42 notifies the reception computer 21 of the calculation result. The calculation result is, for example, image information or the like.

The remote X-ray imaging system 1 having the above-described structure operates roughly as follows. That is, when the user uses the input unit 11 of the information terminal 10 to set and input parameters such as a specific human body model and a specific X-ray imaging condition, the parameter information is sent to the notification unit 12
Is transmitted to the reception computer 21.

When the reception computer 21 receives the parameter information by the reception means 22, the arithmetic processing means 23 extracts a suitable human body model from the human body model database 30 based on the condition of the human body model included in the parameter. To do. At the time of this extraction, there are cases where a human body model is simply obtained by a search, or where a human body model obtained by performing a predetermined calculation on the human body model obtained by a search is obtained.

The notifying means 24 notifies the imaging simulator 40 of X-ray imaging conditions and further parameters including information such as the human body model obtained by the arithmetic processing means 23. Here, the parameters notified by the notification means 24 are X-ray imaging conditions and human body model data. This is because the X-ray imaging conditions can be transmitted as they are, but the human body conditions cannot be calculated unless they are converted into human body model data.

In the image pickup simulator 40, the image pickup calculation processing means 41 performs the image pickup calculation processing relating to the X-ray image pickup simulation based on the parameters including the X-ray image pickup condition and the information of the human body model. The calculation result of this imaging calculation processing is notified to the acceptance computer 21 by the calculation result notifying means 42.

In the receiving computer 21, the calculation result is received by the calculation result receiving means 25, and
It is transmitted to the information terminal 10 by the calculation result transmitting means 26.

In the information terminal 10, the data including the image information as the calculation result and the information such as the parameters is received by the receiving means 14, and the data is displayed by the display means 15.

At this time, it is preferable to reduce the load of input data on the user by presenting a model case for simplifying the condition selection on the display screen of the information terminal 10.

These pieces of information are stored in a specific storage area of the receiving computer 21 as history information in association with the user ID. The history information of each of these IDs includes
A history of past parameters is also included, and can be read as needed.

By selecting the data transmission button, a message for confirming the data is output, and if OK, the data is transmitted to the accepting computer <data transmission process> (S103). If NO, the screen returns to the parameter input screen and data is not transmitted.

The parameter information transmitted from the user's information terminal through the communication line is received by the accepting computer (parameter information receiving process). The reception computer, based on the condition of the human body included in the parameter, searches the human body model database for an appropriate human body model that meets the conditions, or performs an arithmetic processing on the retrieved human body model to obtain a human body model that meets the user's request. Creating information <human body model calculation processing> (S104).

Next, the reception computer 21 receives the parameters including the information about the human body model and the X-ray imaging conditions.
To the imaging simulator 40. The parameters at this time are recorded in the reception computer 21 as history information.

The imaging simulator 40 integrates the X-ray source weak coefficient by using a mathematical model (human body model) of the human body according to the given condition of the human body (human body parameter), and as a result, the X-ray source and the detector are integrated. Physical configuration, line imaging condition (S10
Projection data is calculated in consideration of 5) <imaging operation processing> (S106). Thereby, the imaging calculation processing by the X-ray imaging simulation is performed.

Then, the projection result data (image information) as the calculation result and the input parameters are distributed to the information terminal of the user (user) through the communication line <calculation result transmitting process> (S107). In this way, the calculation result is delivered in the selected output format.

At this time, the information of the input parameter and the image information are stored together from the viewpoint of improving the information processing efficiency when creating a copy of the information or transmitting it to another information terminal. When the image information is transmitted, the parameter information is also transmitted at the same time as the supplementary information.

Further, the image information of the calculation result or the image information and the parameter information is displayed on the display means of the user's information terminal (S108). Then, the charging process is performed according to the data amount of the distributed image information of the calculation result. As a matter of course, it is preferable to perform this charging process for each user.

As described above, according to the present embodiment, the user accesses the management device from the information terminal via the network and executes the arithmetic processing of the X-ray imaging simulator for remotely performing advanced information calculation. Since it can be used as needed, it is possible to obtain the calculation result (actual simulation image) of the advanced simulation without purchasing the very expensive medical image diagnostic apparatus (actual machine) itself.

Furthermore, it is possible to perform simulated imaging any number of times without exposing the patient to X-rays, which is convenient when used for prior confirmation by a doctor. At this time, even for beginners, even a beginner can confirm what X-ray condition is best by a trial & error, such as the setting of X-ray conditions that can only be set by an experienced person. As a result, the difficulty in determining the X-ray condition etc. according to the patient's part is eliminated, and
It is also possible to carry out actual photography after confirming to some extent with an X-ray imaging simulator. In addition, the effect of imaging training for inexperienced radiation technicians can be enhanced.

In addition, since it is possible to find the optimum condition from the image pickup result by the simulation and to reflect the optimum condition in the photographing by the actual machine, unnecessary X
It is possible to reduce the radiation exposure.

Also, from the Web using the information terminal, X
Since the line imaging simulation can be performed, it is possible to easily perform training of the technician anytime and anywhere at a low cost without purchasing a very expensive real machine in an organization that educates a technician such as a radiological technician. .

(Modification) The reception computer 21
Stores information regarding the user ID of a user who has used the X-ray imaging simulator in the past and the parameter corresponding to the user ID. Therefore, the service is 2
In the case of using the third time and the third time, if the conditions are almost the same (only one condition is changed, etc.), a part may be changed so that it is easy for the user to use.

Further, by storing the X-ray imaging conditions (parameters) according to the region to be imaged and the place to be imaged, and accumulating the conditions in case of failure and the conditions in case of success according to the use of the user as a history, The optimum X-ray imaging condition according to a specific imaging site or imaging location may be automatically displayed on the information terminal of the user.

At this time, the acceptance computer 21 stores the user-ID and the parameters for each number of times of use, as well as the history when the user fails in the X-ray simulated imaging or when the X-ray imaging is successful. .

As a result, when the user inputs data such as a human body model, optimum or preferable condition information (range) can be presented. This condition information may be generated based on history information such as past failures and successes. The parameters in the case of success may be extracted from the history information, and the one that is close to the condition may be selected.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIG. Note that, in the following, description of substantially the same configuration as that of the first embodiment will be omitted, and only different portions will be described. FIG. 3 is a system configuration diagram showing an example of the system configuration of the modality simulator system of the present embodiment.

The WWW server 120 includes application software 122 including each simulator of each medical image diagnostic apparatus and a DB 124 including information such as an image database and a customer (hospital) database.
It can be accessed and used from the information terminal 110.

The WWW server 120 is started by a generally called HTTP daemon, has an application, and further has a database of images corresponding to the simulator. The simulator is operated to access the database, It has a structure of returning.

In the hospital information system 130, a modality system 131, which is a medical image diagnostic system including various medical image diagnostic devices, a workstation 132 that can refer to and store image information and the like, and an SP 133 are connected by an in-hospital LAN. Information can be exchanged between the in-hospital LAN and the external network via the proxy server 134. Workstations 132 connected to these modality systems 131
The captured image obtained by the modality system 131 can be read on the side.

The modality system 131 includes various medical image diagnostic apparatuses. For example, it is used that the subject is exposed to X-rays and the X-rays are absorbed by the organs and bones in the subject body. An X-ray imaging apparatus for performing imaging by using the same principle, by collecting and reconstructing projection data obtained as a result of irradiating X-rays from multiple directions with respect to the object using the same principle, a tomographic image of the object is obtained.

As the X-ray imaging apparatus, for example, a so-called "angio apparatus" having a C arm or the like may be assumed. In addition to the above, various medical image diagnostic apparatuses may be assumed in the present embodiment.

In the modality simulator system 100 having the above configuration, the hospital information system 1
From the information terminal in 30 or the information terminal 110, WWW
The server 120 is accessed, and each medical image diagnostic apparatus (eg, X-ray CT apparatus, X-ray imaging apparatus,
A simulation of a nuclear medicine diagnostic device, an MRI (magnetic resonance imaging) device, an ultrasonic diagnostic device, etc.) is performed on the Web.

At this time, when the simulation is performed from the information terminal, the setting parameters when the operation is performed on the system are stored and saved in, for example, the WWW server 120.

Then, the stored setting parameters are accessed from the information terminal in the hospital information system 130,
It can be downloaded to the modality system 131. This allows the same parameters to be used on the actual machine.

The access from the modality system 131 uses the proxy server or the SP, but the realization method differs depending on the hospital environment. Further, the access is not limited to access from within the hospital, but access from the information terminal 110 such as a personal computer that can access the Internet is also possible.

A simulator of a modality system is created on the WWW server 120, and image information and the like expected by the same operation as the actual operation are displayed. Thereby, for example, C
It is possible to display the image expected to be taken by setting each parameter in the T simulator.

The WWW server 120 is made public on the Internet, and a modality simulator is created on it. By doing so, if the WWW server 120 has a simulator, the simulator can be used from anywhere from the information terminal 110 that can be connected to the Internet.

The WWW server 120, more specifically,
The simulator has the following two operation modes. The operation mode is a division of how the user uses the simulator, and there are the "free operation mode" and "operation training mode with advisor" shown below.

The "free operation mode" is a mode in which a simulator having the same screen structure as the actual machine can be operated. This operation mode is a mode used by a person who is proficient to the extent that he / she can freely try various results.

The "operation training mode with an advisor" is an operation technique in which the operator and the advisor communicate in real time by telephone (or including communication means such as chat) while operating a simulator having the same screen configuration as the actual machine. Is a mode to learn. As a result, it is possible to teach operating the simulator by attaching an advisor in a form such as chat or telephone and exchanging information to some extent.

(Contents of WWW Server Processing) Next, the processing procedure of the modality simulator system having the above-mentioned configuration will be described for each of the following operation modes, “free operation mode” and “operation training mode with an advisor”.

(Free Operation Mode) FIG. 4 is a diagram showing a flow of access in the free operation mode. As shown in the figure, first, the WWW server 120 is accessed from the information terminal 110 of the user who desires to use the simulator <access request transmission process> (S201).

When the WWW server 120 receives an access request from the information terminal 110, the WWW server 120 sends an authentication (user ID, password) request to the information terminal 110 <authentication request sending process > (S202). In this way, by making an authentication request for access from the user, it is possible to determine who the user is, and which hospital / where the access is from. Therefore, the simulator function can be restricted (function restriction function). ). In addition, it is possible to make it accessible only to customers (hospitals) and to publish the data with restricted functions as a trial of the next system.

Then, when the authentication request is received, the information terminal 110 displays a display screen for inputting the user ID and password, and the user inputs the user ID and password for using the modality simulator. It can be performed.

The user ID and password entered in the information terminal 110 are WWW from the information terminal 110.
<User ID transmission processing> transmitted to the server 120 (S203).

Then, when the transmitted user ID and password are received by the WWW server 120,
If the authentication process is performed and the authentication process is successful,
The WWW server 120 transmits the modality system selection screen information for displaying the modality system selection screen to the information terminal 110 to the information terminal 110 <modality system selection screen information transmission process> (S2
04).

In the information terminal 110, for example, FIG.
As shown in (A), the moderation system selection screen 210 is displayed on the browser. On this moderation system selection screen 210, a CT system, an ultrasound system, an X-ray imaging system, a nuclear medicine diagnostic system, an MRI
(Magnetic resonance imaging) system or IVR-
It is possible to select the type of modality system for which simulation is desired, such as a system such as CT or other various medical image diagnostic systems similar thereto, and the model of each system can also be selected. Figure 6
In the example of (A), it is possible to select, for example, for each version of the CT system. This allows you to choose what to use for the virtual modality system.

Returning to FIG. 4, when a specific modality system is selected on the modality system selection screen of the information terminal 110, the information indicating the selection is WWW.
<Modality system selection information transmission process (modality selection information transmission means)> transmitted to the server 120
(S205).

The WWW server 120 prepares to transmit the simulator screen of the selected specific modeality system, and displays the operation mode selection screen for selecting either the free operation mode or the operation mode with the advisor. The operation mode selection screen information to be performed is transmitted to the information terminal 110 <operation mode selection screen information transmission process> (S206).

When the operation mode selection screen is displayed on the information terminal 110 and the free operation mode is selected, information indicating that the free operation mode is selected is displayed on the WWW server 1.
<Free operation mode selection information transmission process> transmitted to 20 (S207).

In the WWW server 120, the simulator screen of the specific modality system is displayed on the information terminal 110 so that the simulator of the selected specific modality system can be operated in the free operation mode. Information is transmitted to the information terminal 110 <Simulator screen information transmission processing (Simulator screen information transmission means)> (S208).

Furthermore, the manual screen information is transmitted to the information terminal 110 so that the manual screen showing the operation manual in the simulator is displayed on the information terminal 110 <manual screen information transmission process> (S209 ).

In the information terminal 110, for example, FIG.
As shown in (B), the simulator screen 220 of the X-ray CT simulator is displayed on the browser.

The simulator screen 220 is, for example, a screen simulating an operation screen of an actual X-ray CT apparatus, or a screen displayed by a simulator of an actual X-ray CT system is formed on a browser. From this screen, the user can try various operations. On the simulator screen 220, parameters such as human body model parameters and X-ray imaging conditions can be set and input, or corresponding similar parameter information from the past history can be referred to or selected together with the image information, and a predetermined operation can be performed. The imaging simulation of the X-ray CT apparatus can be performed according to the procedure.

In the example shown in the figure, the case where the simulator of the X-ray CT system is selected has been described.
Depending on the selection of each simulator such as an ultrasonic system, an X-ray imaging system, a nuclear medicine diagnostic system, an MRI (magnetic resonance imaging) system, or a system such as IVR-CT or other similar medical image diagnostic systems. Then, each simulator screen will be displayed on the browser.

Further, even in the same X-ray CT system, an operation screen having a layout corresponding to the version of the model is displayed.

Further, in the information terminal 110, as shown in FIGS. 6C and 7, for example, the manual screens 230 and 240 are displayed on the browser by necessary operations.
Is displayed. That is, the user can operate while displaying the manual on the screen and referring to the manual.

On the manual screen 230, it is possible to search for an imaging method and the like according to the imaging site, and it is possible to refer to the necessary optimum setting information on the manual screen 230. Similarly, on the manual screen 240, it is possible to refer to the optimum setting information according to the shooting content.

The example of FIG. 6C shows an example in which the head is selected and set as the imaged region, and how the image of this head can be effectively photographed and its effective You can manually search for different methods.

In the example of FIG. 7, it is possible to retrieve a manual from another method, for example, the contents of photographing.

Based on these setting information, optimum setting can be performed or parameters can be automatically set.

In addition to the manual contents attached to the product, there is a manual screen for displaying the parameters expected to be the best from the part or method to be photographed (not the explanation of the function, but the operation method from the one to photograph). The idea to derive).

Returning to FIG. 4, when the user performs a desired operation when the simulator screen or the manual screen is displayed on the information terminal 110, the simulator including these setting parameters and information corresponding to the operation. The operation information is transmitted to the WWW server 120 <Simulator operation information transmission process> (S211).

On the other hand, in the WWW server 120, the simulator operation information operated from the simulator screen in the information terminal 110 is received via the network, and the modality simulation arithmetic processing is performed based on the simulator operation information. That is, the DB is searched based on the simulator operation information, and the DB search result information, which is the calculation result of the calculation process of the modality simulation, is transmitted to the information terminal 110 <DB search result information transmission process> (S212).

The information terminal 110 can receive the DB search result information and display the DB search result information on the browser.

According to the parameters set by the user,
An image expected when scanned (here, CT is taken as an example) is displayed. This image is stored in the database, and the image found by searching for the content of the parameter is displayed on the display screen of the user's information terminal.

By repeating the steps S211 and S212, the modality simulation is performed by the user.

Thus, in the free operation mode,
Since effective shooting methods and detailed instruction manuals can be displayed depending on the shooting site, it is possible to acquire technology at our own pace. Of course, the user can operate the simulator by himself.

(Operation Training Mode with Advisor) Next, the processing in the operation training mode with advisor will be described with reference to FIG. The flow of FIG. 5 shows an example in which the advisor points out an error of the user while looking at the operation log of the WWW simulator.

Here, the "operation training mode with an advisor" means that the operator and the advisor communicate in real time by telephone (or including communication means such as chat) while operating a simulator having the same screen configuration as the actual machine. This is a mode in which you learn the operation technique while taking it.

First, in the processing from S301 to S306,
S in the process shown in FIG. 4 in the case of the free operation mode
Since the processing is substantially the same as the processing from 201 to S206, detailed description thereof will be omitted.

That is, when the WWW server makes an authentication request and the user inputs an ID and a password,
The system selection screen is displayed, and when the system of a specific modality is selected, the operation mode selection screen is displayed.

From here, the above "free operation mode"
Unlike the above case, when the operation mode selection screen is displayed on the browser of the information terminal 110 and the operation with advisor (operation training) mode is selected, information indicating that the operation with advisor mode is selected is displayed on the WWW server 120. <Operator mode selection information transmission process with advisor>
(S307).

When the WWW server 120 receives the information indicating that the advisory operation mode has been selected, the WWW server 120 transmits a connection request to the advisor information terminal 140 <connection request transmission process> ( S308).

The advisor information terminal 140 transmits a connection response corresponding to the connection request to the WWW server 120 <connection response transmission process> (S309).

Upon receiving the connection response, the WWW server 120 causes the information terminal 110 to display the simulator screen of the specific modality system so that the simulator of the selected specific modality system can be operated in the operation mode with the advisor. As described above, the simulator screen information is transmitted to the information terminal 110 <Simulator screen information transmission processing> (S311).

As a result, the information terminal of the advisor and the information terminal of the user can communicate with each other via the Web server.

On the information terminal 110, when the simulator screen is displayed and the operator-operated mode with an advisor is selected, the user can perform a dialogue regarding the operation of the advisor and the simulator in real time. When asking a question, the question information is sent from the information terminal 110 to the WWW server 1
<Question information transmission process> (S31
2) Further, the WWW server 120 transmits the question information to the advisor information terminal 140 (S31).
3).

Upon receiving the question information, the advisor information terminal 140 inputs the answer to the question, and the entered answer information is transmitted from the advisor information terminal 140 to the WWW server 140 <Send Reply Information Process> (S314), and the reply information is WWW.
The information is transmitted from the server 140 to the information terminal 110 (S315).

When the information terminal 110 receives the answer information, the information terminal 110 performs predetermined operation input or setting input of parameters based on the answer, so that the simulator operation including information corresponding to these setting parameters and operation is performed. The information is transmitted to the WWW server 120 <Simulator operation information transmission processing> (S316).

The operation information is transmitted from the WWW server 120 to the advisor information terminal 140 so that the advisor information terminal 140 can successively monitor it <Operation monitoring information transmission process> ( S317).

On the other hand, the WWW server 120 searches the DB based on the simulator operation information,
B Search result (display) information is transmitted to the information terminal 110 <DB search result display information transmission process> (S318).
When the information terminal 110 receives the DB search result information, the DB search result information can be displayed on the browser.

On the other hand, when the information terminal 140 of the advisor judges that there is an operation error based on the operation monitoring information, the operation error pointing information indicating the operation error is sent from the information terminal 140 to the WWW server. 120 (S321), and further, the operation error indication information is transmitted from the WWW server 120 to the information terminal 110 <Operation error indication information transmission process> (S32)
2).

Here, in the operation monitoring by the advisor, the display mode displayed on the display screen of the information terminal 140 on the advisor side is, for example, the screen operated by the user displayed on the information terminal 110. While displaying the user operation screen (may display each operation screen of multiple users, respectively) of almost the same layout configuration,
It is preferable that the display mode is such that information regarding the content operated by the user (for example, "operated") is displayed and can be completely monitored in real time. Then, while monitoring, a comment such as an operation error is provided to the user.

As a result, the advisor is
Instructions can be sequentially issued each time one operation is performed, and the user can receive advice as if there is an adjacent advisor. This instruction may be provided by voice or text.

In this way, S312 and S3
The user is trained by repeating 22.

Further, the operation contents of these users are
The data is stored on the WW server 120 and can be used as data for advisor monitoring, and can also be used later for analysis of user operations.

In the advisor-equipped operation training mode, it is preferable to carry out the charging process for each use, the number of questions, and the amount of data.
In this case, in the free operation mode, it may be assumed that the trial version simulator or the like may be released for free on the Web, and further, the simulator may be disclosed only to a specific user. In addition, although it is not necessary to perform billing processing, the amount of data depending on the system configuration,
Alternatively, the charging process may be performed according to the modality and further according to various versions.

According to such an "operation training mode with an advisor", the advisor can monitor the operation contents of the user in real time and can point out an error or an operation error. Further, the user side can ask the advisor a question regarding the operation, and the answer to the question can be obtained from the advisor, and the user can perform the operation while following the advice.
This allows the user to communicate with the advisor and learn the operation of the medical image diagnostic apparatus while asking the advisor a question.

In the modality simulator system according to the present embodiment, in addition to the usage modes in the free operation mode and the operation training mode with an advisor, the following "operation 1",
It has various usage patterns or functions of "operation 2", "operation 3", "operation 4", and "operation 5".

(Operation 1) First, a user such as a doctor uses an actual modality system, which modality should be used after each simulator of each modality on the Web is tried from the medical condition. It is envisaged to decide the combination to be performed. Information about the results of such trials is accumulated in a form corresponding to the medical condition, and other users can display the information (information regarding which modality is best to use) by using the medical condition as a key. Becomes

That is, it is possible to have a function of automatically determining the combination using the modality system from the medical condition and automatically displaying it.

[0161] For example, a display mode such as "It is effective to perform the CT-like imaging like *** and then the MRI-like imaging like ***" is used. Is preferred.

Even if the automatic display function is not provided, the image of the simulation result is confirmed based on the case, for example, in case A, using a simulator of the CT system, and the image is not suitable for diagnosis. If
It is also possible to compare images by selecting images with different modalities depending on the symptoms of the disease and trying them, such as performing an MRI system simulation. improves.
In this way, it is effective as an assist when making a diagnosis by combining ultrasonic diagnosis and MRI etc. for each case.

Secondly, the training for setting the parameters of each modality, which is difficult for a beginner in the modality, can be tried with a Web simulator, and effective parameters are downloaded to the modality system from the tried parameters. However, by using the above parameters in an actual modality (medical image diagnostic apparatus), the test environment and the execution environment can be unified.

That is, the parameters stored in the simulator of the WWW server can be downloaded to the modality system and used (WWW server → hospital). In particular, various parameters such as *** parameters of famous doctors can be prepared on the WWW server, and useful information regarding an effective imaging method can be easily acquired.

Here, when the parameters are downloaded, it is preferable that each parameter can be downloaded for each modality, and each parameter is stored in each storage unit of each modality of the modality system. This is because each parameter can be immediately used in each medical image diagnostic apparatus.

[0166] Further, when downloading the above-mentioned parameters (particularly, the parameters set by a famous doctor etc.), it is preferable to carry out a billing process.

Incidentally, as a concrete example of the above parameters,
Information such as X-ray imaging conditions can be given as the parameters set when using the simulator of the X-ray imaging apparatus and the X-ray CT apparatus.

The X-ray imaging conditions included in the above parameters include X-ray conditions (tube voltage, tube current, X-ray pulse width, frame rate, field size), imaging region (heart, lungs, intestines, or feet). ) Or area of interest, shooting size,
Examples include distance, X-ray direction (front, side), patient data, and the like.

Further, as parameters set when the simulator of the MRI (magnetic resonance imaging) apparatus is used, TR (repetition time), TE (echo time), slice thickness, matrix size (image size that can be obtained after imaging) ), Imaging method, presat, cross section / encode, total number of times, and the like.

In addition, the parameters set when using the NM simulator are: imaging method (static collection / dynamic collection / spect collection, whole body collection, whole body spectrum collection), collection angle,
Examples include RR interval (number of divisions), UFOV (camera field of view range), camera rotation speed, image rotation speed, camera rotation, pause time (imaging stop time), and the like.

Further, as the parameters, in addition to the above-mentioned parameters, information such as conditions of the human body can be cited. Examples of the parameters of the human body model indicating the human body conditions include height, weight, body thickness, age, and sex.

(Operation 2) Further, it is preferable to display a result such as an image as a sample of the photographing result first and select an image to be photographed so as to display a manual so as to derive an effective photographing method. .

This has the advantage that an effective photographing method can be easily found. As the display mode of the manual screen, for example, "***
It is preferable to display such as "If the time of * is set to * seconds and scanning is performed, the administration speed of the contrast agent and the scanning speed are well matched."

Further, the corresponding parameter may be automatically displayed or automatically set from the image. For example, when a CT image is selected, the CT parameter conditions are automatically displayed or set, and the MR
When the image of I is selected, the condition of the MRI parameter can be automatically displayed or automatically set.

In addition, for example, when it is desired to acquire an image of a part of the heart, when the heart is selected as the part, various display modes (for example, images imaged by different parameter conditions or different modalities) are simulated. ) Heart images are displayed in a list (for example, in a thumbnail image format), and when the image desired to be acquired is selected, the modality type of the corresponding image and its parameter are automatically displayed or automatically set. It can also be configured.

Further, when the heart is imaged, the appearance of the reference image also differs depending on the image capturing method.
For example, an image a of the heart taken based on the parameters set by the doctor A, an image b of the heart taken based on the parameters set by the doctor B, ... Are displayed, and these images a, b ,. The user can visually check and select a desired image type from among them, obtain corresponding parameters, and automatically set the parameters. Of course, the parameters can be changed manually if necessary.

(Operation 3) A method for effectively photographing a desired place can be displayed on the manual screen, or effective parameters can be placed on the WWW server so that the desired place can be accurately and efficiently taken. To do so.

As a result, it is possible to make the most of the function of the apparatus and perform imaging specialized for clinical contents. As a display mode of this manual screen, it is preferable to display, for example, "to effectively image an artery, download the parameter on the *** server and take an image".

(Operation 4) As shown in FIG. 8, the setting parameters between the server (various WWW servers) 120 and the modality systems 141 and 142 of each hospital, and the SP (information processing device) 150 are set. It can also be used for data exchange and data backup. As a result, it is possible to unify the setting contents in the modality system in the hospital and automatically update the parameters.

In addition, access SP150 in the hospital (S
By accessing the WWW server 120 from P150), information unique to the hospital can be stored in the simulator (system) of the WWW server 120. In addition, the parameters of the hospital can be saved in the simulator of the WWW server 120 (hospital → WWW server). In this way, the parameters can be distributed such that the parameters are exchanged between different systems at different locations.

As described above, every time the simulator is used from the information terminal or the hospital information system, the parameters set and input are stored in the WWW server and operated from the information terminal or the hospital information system. Based on the instruction, the stored parameters on the WWW server can be downloaded to a specific storage area of the medical image diagnostic apparatus of the corresponding type or model in the hospital information system.

(Operation 5: Function Restriction Function) Further, as the processing content of the server, for example, function restriction (identification of a function to be used according to a hospital) may be performed.

That is, in a specific hospital A, a system of (y1 function + y2 function + main function) medical image diagnostic apparatus is used, and in another specific hospital B, (y2 function + main function) medical image is used. I am using a system of image diagnostic equipment,
It is assumed that another specific C hospital uses the system of the medical image diagnostic apparatus (y1 function + y3 function + main function).

In this case, depending on the type of device for each hospital,
Since the functions are different, it is not possible to use common parameters for each hospital device.

Therefore, for access from the information terminal of the system in the specific hospital A, y3 of this simulator is used.
The simulator is controlled so that the functions are limited, and the access from the information terminal of the system in B hospital is
The function 1 and the function y3 are controlled to be restricted, and the access from the information terminal of the system in the hospital C is controlled to restrict the function y2 of the simulator.

As described above, by combining the access control and the function restriction control, it is possible to divide the functions according to the access of each hospital, provide a simulator according to each hospital, and provide each client hospital with a simulator. You can set the environment,
It is also possible to save the set parameters and the like.

As an example of the function restriction, for example, the function restriction of the simulator of the new version of the medical image diagnostic apparatus can be mentioned. It is also possible to limit the functions of the simulator of the medical image diagnostic apparatus that is issued as a trial version, or to open all the functions if access is made from a hospital on the customer list.

Even if the model is set on the first modality selection screen, the medical image diagnostic apparatus has, for example, an imager, an MO (magneto-optical disk apparatus), a three-dimensional image processing function, a heli-cal scan function, etc. Since there are variations such as the option not being provided, it is possible to deal with these variations according to the variations of the apparatuses for each hospital by limiting the functions.

Furthermore, since there may be a simulator that cannot be disclosed to a specific hospital with the latest equipment and the equipment under study, the function restriction function and the access control function are effective in such a case.

Further, rather than providing all the functions of a full-scale simulator to beginners such as students, it is possible to limit the functions and use it as a simple simulator with only simple operation parts.

On the contrary, although the y2 function cannot be used in the medical image diagnostic apparatus of the hospital A, only when the hospital C in the customer list makes an access, all the functions including the y2 function are included in this simulator. May be available.

As described above, according to this embodiment, various medical image diagnostic apparatuses (modalities) are available on the Internet.
By providing the Web simulator, it is not necessary to secure an actual machine, and anyone (in-house technician or the like) can access, operate and use the machine.

Further, it becomes possible to efficiently train the device users such as engineers even during the operation training such as the training of technicians and the training of new employees, and it is possible to educate the device users at low cost, which is suitable for educational institutions. Can be used for.

Particularly, in the operation training mode with an advisor, the operation state of the user is constantly monitored by the advisor, so that it is possible to receive indications and instructions from the advisor in real time during the simulation operation. . Moreover,
You can also get real-time advisor answers to user questions.

In addition to the telephone and the chat, various kinds of communication means through the Internet line can be assumed for the dialogue with the advisor. For example, by using the communication means for broadband, the information of the user can be obtained. The terminal may be configured to receive advice while browsing the face of the other party (advisor).

Furthermore, since it can be tried without an actual machine, it is possible to try by repeating the medical image diagnostic apparatus for which it is difficult to set conditions such as parameter setting.
It is also possible to search for the parameter corresponding to the optimum image by the error. And, the parameter of the result which I tested with the simulator on the Web and thought that this was good,
It can be used and operated in the main body of the medical image diagnostic apparatus.

In other words, since it is possible to easily confirm the change state of the result due to the change of the parameter, it is also useful to train an operation specialist. In addition, the educated result can be actually downloaded to the device. So
The result of the practice can be directly linked to shooting or actual work.

As described above, in the modality system simulator, these effective parameters can be created, the parameters to be used can be determined according to the practice results, and the same parameters can be downloaded in the modality system by downloading the parameters. Can be used.

Further, there is a possibility that a simulator or an assist can be quite useful in the educational field of students and the like.

Since the web server is communicable with the hospital information system of each hospital or other systems in other places, the simulator can be used in any place, and each medical image diagnostic apparatus can be used in each place. Even in the case of distributed installation, the optimum parameters according to the device tested on the Web server can be downloaded from the information terminal to each medical image diagnostic device (of each hospital). The parameters of the medical image diagnostic apparatus at each place can be set from one place.

In addition, the parameters operated by a famous doctor can be used at each place, which can be very useful for clinical practice. Then, various parameters in CT, MRI, etc. can be provided as a common method in various modalities.

It can also be used for treatment planning using multi-modality. For example, in formulating a radiation treatment plan, an optimal parameter such as irradiation conditions is obtained after performing a simulation using a Web simulator of an X-ray CT system to obtain an image. Then, the parameters including the irradiation conditions are downloaded and stored in the storage device of the radiotherapy apparatus network-connected to the in-hospital system, and the radiotherapy apparatus performs the radiation irradiation to the subject based on this. You can also

Further, in sales such as sales of a new medical image diagnostic apparatus, it can be used in commercials for customers who introduce the functions and operational feeling of the medical image diagnostic apparatus to the customer. Can be used.

Further, information such as which person accesses from what place and what operation is performed can be grasped by accumulating the operation log information for each user ID, and the operation log information can be monitored. It can also be applied to various types of information analysis using tests.

Furthermore, a manual for searching for a method of determining a photographing parameter from an image or a method of determining a photographing parameter from a medical condition is displayed on the browser. As a result, the technician can easily search for a shooting method, and can easily shoot an image that he / she wants to shoot without being familiar with the functions of the modality system. This is effective because an effective image can be easily taken.

The configuration may be such that only the simulator of the MRI (Magnetic Resonance Imaging) device can be used from the web server, or only the simulator of the ultrasonic diagnostic device can be used from the web server.

[0208] Further, the advisor information may be used by patterning a question or the like if it can be patterned to some extent at the stage when some data is accumulated. At this time, the operation training mode with an advisor can be carried out without having an information terminal on the advisor side.
