In the case shown in the figure, the X-ray CT system is shown installed in the medical institution 3003, but an MRI or other medical device may be used.

To simplify the explanation, the construction of an X-ray CT apparatus, which is one of the medical equipment, is shown in FIG. 2 and explained.

As shown in the figure, the X-ray CT system includes a gantry 100 for irradiating a subject with X-rays and detecting X-rays transmitted through the subject, placing the subject on the gantry 100 and mounting the subject on the gantry 100. Conveying device 300 for conveying to the cavity
The operation console 200 is configured to perform various operation settings on the gantry 100 and the transport device 300 and reconstruct and display an X-ray tomographic image based on the data output from the gantry 100.

The gantry 100 has the following configuration including the main controller 1 which controls the whole thereof.

Reference numeral 2 is a rotating body having an interface for communicating with the operation console 200 and a cavity for accommodating a subject (examinee). Inside, there is an X-ray generating source of X-rays. A tube 4 (driven and controlled by an X-ray tube controller 5) and a collimator 6 having a slit that defines an X-ray irradiation range are provided. A filter 7 is provided between the X-ray tube 4 and the collimator 6.
The filter 7 attenuates X-rays with lower energy (X-rays with longer wavelength) and is used for the purpose of reducing the exposure dose of the subject.

Further, the rotating body 3 has an X-ray transmitted through the subject.
As shown in the figure, the detecting element 8 which is an X-ray detector having a plurality of (approximately 1000) detecting elements for detecting the rays along the substantially circumference of the cavity of the rotating body, The data collection part 9 which collects is also provided. X-ray tube 4 and detector 8
Are provided so as to face each other with the hollow portion sandwiched therebetween, and are held by the rotating body 3 and rotated while maintaining the relationship therebetween. This rotation is performed by the motor controller 1
It is performed by the rotary motor 10 driven by the drive signal from 1.

It is an operation panel provided with various switches including F. Reference numeral 15 is a positioning light for irradiating an optical mark for positioning the subject toward the subject.
Reference numeral 6 is an interface for connecting to the carrier device 300.

The detector 8 may have one or more detector elements. Incidentally, a system composed of one row of detector elements is called a single-slice X-ray CT system, and a case of multiple rows is called a multi-slice X-ray CT system.

The main controller 1 analyzes various commands received via the I / F 2, and based on that, analyzes the X-ray tube controller 5 and the motor controller 11 described above.
In response, various control signals will be output. The main controller 1 also performs a process of sending the data collected by the data collection unit 9 to the operation console 200 via the I / F 2.

On the other hand, the carrier device 300 has the following structure including the main controller 21.

Reference numeral 22 denotes an operation panel composed of an instruction switch for instructing up and down movement of the transfer device 300, a switch for instructing movement of the top plate, and the like. It is a sensor group that detects the amount of extension toward. Reference numeral 24 is a motor for changing the height of the apparatus including the top plate, and 25 is a motor controller for applying a drive signal thereof under the control of the main controller 21. Reference numeral 26 denotes a top plate on which a subject is placed. As a material of the top plate, X-rays are easily transmitted, and since it has a strength to hold the state where the subject is placed, a foam material such as acrylic is used as C.
It is reinforced by being wrapped with FRP (Carbon Fiber Reinforced Plastics). 27 is Z of the top plate 26
A motor for performing axial conveyance, 28 is the motor 27
Is a motor controller that applies a drive signal to the. An interface 29 is connected to the interface 16 of the gantry 100.

In the above structure, the main controller 21 of the carrier device 300 follows the instruction from the operation panel 22 or the instruction from the operation console 200, and the top 2
6 will be controlled in the Z-axis direction. In addition, according to an instruction from the operation panel 22, the device itself is lifted, that is, the top plate 26 is lifted.

Next, the operation console 200 will be described. The operation console 200 is a so-called workstation, and as shown in the figure, a CPU that controls the entire apparatus.
51, the RO storing the boot program and the BIOS
Starting with M52, RAM53 that functions as a main memory,
It has the following configuration.

The HDD 54 is a hard disk device, and stores a diagnostic program for giving various instructions to the OS and the gantry 100 and reconstructing an X-ray tomographic image based on the data received from the gantry 100. There is.

The VRAM 55 is a memory for expanding the image data to be displayed, and by expanding the image data or the like here, it can be displayed on the CRT 56. Reference numerals 57 and 58 are a keyboard and a mouse for making various settings. Reference numeral 59 is an interface for communicating with the gantry 100, and 60 is a network interface (details will be described later).

In the above structure, the gantry 100 and the transfer device 300 have many mechanical operating parts.
For example, to describe the gantry 100, in order to rotate the rotating body 3, a bearing for smoothly performing the operation is usually provided on the lower end surface of the rotating body 3. The same applies to tilt angle control, and the tilt control cylinder is also a mechanically operating part. Further, the X-ray tube 4 normally generates X-rays by irradiating the anode electrode that rotates at a high speed with thermoelectrons, and has a mechanically operating portion.

Further, since the driving power to the X-ray tube 4 on the rotating body 3 and the signal from the X-ray detector 8 are received, the rotating body 3
Is provided with a slip ring electrode along its circumference. A known brush electrode that comes into contact with the slip ring at a predetermined pressure naturally wears out with the operation of the rotating body, so that replacement work is required within a relatively short period of time.

As described above, the mechanically operated parts are fatigued according to the operating amount (time), and the remaining life as parts is inevitably shortened. Further, there are some parts that are not mechanically operated but fatigue due to energization. For example, the X-ray detector 8 also gradually fatigues depending on the energization time. Some parts have fatigue factors that are both mechanical and energized. For example, various motors can be cited, and the X-ray tube 4 can be regarded as one of the elements.

In any case, these parts that become fatigued due to energization and / or mechanical operation are also objects to be replaced during normal maintenance, and hence they are collectively referred to as "consumable parts" below.

On the other hand, it can be considered that the frame of the gantry 100 and electronic circuits such as the controller 1 do not fatigue. In addition, "fatigue" here does not mean "fault." If a failure occurs, it will be replaced, but it is practically difficult to predict it.
It is called a non-consumable part.

As described above, the gantry 100 can be divided into consumable parts and non-consumable parts. The same applies to the operation console 200 and the transport device 300. The same applies to other medical devices such as an MRI system.

In the embodiment, the management server 2000 is notified of the usage contents of the medical devices installed in each medical institution (3001 to 3003 in FIG. 1).
The management server 2000 stores a database of not only the types of medical devices installed in each medical institution, but also the degree of consumption of each consumable part and non-consumable part, the basic price, and the like.
As a result, at least the following three points can be realized.

First, by accumulating the notifications of the contents of use installed in each medical institution, the purchase price or the trade-in price of each medical device is updated, and each medical institution can update the purchase price or the trade-in price. Notify online. As a result, the medical institution side can know the current purchase price and trade-in price when they want to know without making a troublesome request for assessment.

Second, on the management company side, when a medical institution requests a trade-in or sale, it becomes possible to judge how much the cost should be to withstand reuse.

Thirdly, the management company side can know the consumption level of the consumable parts of the medical equipment installed in each medical institution, which can be used as a reference when deciding the date of the next maintenance.

<Description of Calculation of Residual Value (Residual Life)> To detect the degree of wear of a consumable component that constitutes a medical device, for example, a bearing that supports the rotation of the rotating body 3 in the gantry 100 of the X-ray CT system. Can be realized by counting the number of rotations of the bearing. However, adding a configuration for monitoring the actual operating state of each consumable part has a cost problem, and it is necessary to consider even the fatigue of the configuration itself for monitoring, which is not realistic. Absent.

In this respect, in the case of MRI and X-ray CT, the operation of each constituent element (gantry, transfer device) is controlled from the operation console, so that the consumable parts of each constituent element are indirectly controlled based on this. You can know the operating status.

For example, in the case of X-ray CT, the gantry 100
Rotating the rotating body 3 for positioning (the X-ray tube 4 on the rotating body has the detector 9 in a non-driving state = a non-energized state),
It actually rotates during scanning (supplying drive power to the X-ray tube 4 and the detector 9 = energized state). In the case of a bearing, since it depends purely on the rotation speed of the rotating body 3, it is possible to detect the degree of wear of the bearing with a function having the total rotation speed in the non-energized state and the energized state as an argument.

It has been confirmed by the applicant that the degree of wear of the electrode brushes (there are electric signal brushes and power source brushes) in contact with the rotating body 3 differs depending on whether the electrodes are energized or not. There is. Specifically, when the life of the power supply brush when not energized is N1, the life of the power supply brush when energized is N2, the number of revolutions of the rotating body 3 when not energized is R1, and the number of revolutions when energized is R2, the power supply brush The consumption degree W of is obtained by the following arithmetic expression.

W = (R1 / N1 + R2 / N2) Then, this is multiplied by the safety factor “S” to obtain Ws = S · (R1 / N1 + R2 / N2), and when “Ws” becomes “1” Then, it is judged that it has reached the end of life.

In other words, the remaining life of the power brush is "1.
-Ws "(which becomes a value of 1 or less), the residual value of the power brush is" value when not in use "x (1-W
It can be judged in s). That is, in general, the value V of a consumable part can be calculated as V = “value when not in use” × (1−consumption degree). In the above example, the residual value changes linearly with the consumption level, but it does not necessarily have to be linear and may have an appropriate curve.

Further, since the X-ray tube 4 is consumed depending on its driving time, if the elapsed time during scanning or the rotation speed of the rotating body 3 is constant, the rotating body at the time of energization is turned on. The degree of wear can be calculated from the number of revolutions of 3.

As described above, it can be understood from the above description that the degree of wear of the consumable parts in each component can be detected from the content of the instruction from the operation console in the medical equipment, especially the medical equipment using the computer. See. Therefore, the server 2000 is notified of the information indicating the operating status of the medical device installed in each medical institution, and the server 2000 cumulatively adds the operating status of each consumable part from the initial delivery.

The value of the non-consumable part is set to 0 when the product is delivered and installed as a new product at the medical institution, and is reduced according to the elapsed time (actually, in months). In the embodiment, the residual value of the non-consumable component is calculated so as to be attenuated by the function f0 (T) curve as shown in FIG. 11 (remaining value = price at the time of new product × f0 (T)).

Therefore, by summing up the residual values of the consumable parts and the non-consumable parts, the residual value of the medical device as a whole can be calculated. However, it is necessary to add information that depends on the market. Therefore, when the residual value of the medical device as a whole is calculated, it is multiplied by an appropriate coefficient (value less than 1) to present the trade-in price to the user, and the appropriate fee is added to it to set the reuse price. It is desired to do.

<Structure and Operation on Medical Institution Side> FIG. 3 is a conceptual view of the structure of a medical device installed in a medical institution. In the figure, reference numeral 3010 denotes an X-ray CT system as a medical device, and reference numerals 3011 and 3012 denote similar medical devices (MRI, angio apparatus, etc. may be used). Each system is given a unique system ID. "C1-00128" and "M" in the figure
3-10203 "and" C1-00135 "are the IDs. For simplification of explanation, it is assumed that the first character "C" indicates X-ray CT and "M" indicates MRI. It is assumed that these IDs are stored in advance in the operation console of each medical device.

A data collection device 3100 receives information indicating operation contents from the medical devices 3010 to 3012 and cumulatively stores the operation contents. Then, the operation contents of each medical device are accumulated every appropriate period, for example, one week, and the accumulated data is stored in the server 2 as data.
Notify 000. Resets internal data when notification is complete.

As shown in the figure, the data collection device 3100 may be provided with a plurality of medical devices depending on the medical institution, and can be centrally managed, and the notification to the server 2000 can be realized by one device. Points and data collection device 3
100 has a simple function, consumes less power, and can be constantly turned on. In other words, if the function of notifying the server 2000 is added to the operation console of each medical device, the operation console must be powered on regardless of the medical practice, and the operation console Number of servers 2
000 is required, and the maintenance related to the connection with the server 2000 may be increased by a corresponding number. However, this is a desirable example, and the data collection device is not always essential. In short, any device may be used as long as it has a means for notifying the server 2000 of the operating status of the medical device.

The structure of the data collection device 3100 is as shown in FIG. 4, for example. In the figure, 3101
Is a network interface (LAN side) for receiving information from each medical device in the medical institution, and for example, Ethernet can be used. 3102 is a network interface for connecting to the server 2000, and may be any interface as long as it can communicate with the Internet. Reference numeral 3103 is a CPU that controls the entire apparatus, and reference numeral 3104 is a ROM that stores the operation processing procedure of the CPU 3103. 3105 is the CPU 3
This is a RAM used as a work area of 103. Three
Reference numeral 106 denotes a hard disk device (HDD) that functions as an external storage device, and an internal area for storing an ID (user ID) peculiar to a medical institution to be installed and notification from each of the medical devices 3010 to 3012 are given. A status file is reserved to receive and store operational information.

This status file has a structure shown in FIG. 5, for example. As described above, a unique ID is assigned to each medical device (each operation console). When each medical device performs an operation for its diagnosis, the control content outputs an instruction to each component (gantry, carrier device, etc.), and the same content is the ID of each medical device as a header. The data collection device 3100 is notified.

Since the data collection device 3100 can determine which medical device the data is from by checking the received header, the data collection device 3100 responds to the parameters necessary for calculating the wear level of each consumable part according to the control contents that follow. Cumulative addition to the data field. As a parameter, for example, X
In the case of the line CT, as shown in the figure, the rotational speed G0 of the rotating body 3 of the gantry 100 when not energized, the rotational speed G1 when energized, and the like are specialized for each medical device. Has become.

When the preset date and time (for example, Sunday midnight) comes, the contents of the status file are notified to the server 2000. This notification content has the format shown in FIG. 6, for example. An ID for identifying the medical institution at the beginning (user ID in FIG. 4), and then
An ID for identifying a medical device and its status content are set as one set, repeated for the existence of the medical device, and a code indicating the data end is added at the end.

The configuration of the data collection device 3100 installed in each medical institution and the outline of its operation have been described above. The CPU 3103 of the data collection device 3100 may operate according to the procedure shown in FIG.
It is also the processing procedure of the program stored in 3104).

First, in step S1, it is determined whether or not there is a reception from the medical device via the network interface 3101, and the reception is awaited. If there is a reception, the process proceeds to step S2, and it is possible to determine which medical device the data is from by examining the header of the data. Therefore, the received data is analyzed based on the determination result, and the data is dealt with. Extract the parameter and add it cumulatively to the corresponding position in the status file.

Next, in step S3, the server 200
It is determined whether the transmission time for 0 has come. If not, the process returns to step S1 to prepare for the next reception.

If it is determined that it is time to send the data to the server 2000, the process proceeds to step S4, data of the data format shown in FIG. 6 is generated, and the data is sent to the server 2000 via the network interface 3102. To do. When this transmission is completed successfully, the contents of the status file are cleared to zero in step S5, and the process returns to step S1.

<Configuration and Operation on Server Side> Next, the server 2
The configuration and operation of the H.000 will be described.

FIG. 8 is a block diagram of the server 2000. In the figure, reference numeral 2001 is a CPU that controls the entire apparatus, and reference numeral 2002 is a ROM that stores a boot program, a BIOS, and the like. Reference numeral 2003 denotes a RAM used as a work area for the CPU 2003.
A program that functions as S or a server is loaded and executed. 2004 is a keyboard, 2005
Is a pointing device such as a mouse. 2006
Is a network interface for receiving notifications from medical institutions. Reference numeral 2007 denotes a display control unit that performs control related to display, and has a VRAM inside.
Reference numeral 2008 denotes a display unit (such as a CRT) that displays an image based on a video signal from the display control unit. A hard disk device 2009 stores an OS and programs that function as a server, and various database DBs that are referred to when operating as a server.

As the DB, as shown in the figure, the user DB,
There are a component DB and a system DB, which will be described below.

The user DB has a structure as shown in FIG. 9, and general data such as the ID of each medical institution (which matches the user ID in FIG. 4), the name of the medical institution, the address, and the password. In addition, the system ID of the medical device installed in each medical institution is stored. The manufacturing date of the system is stored on the right side of the system ID. Please note that this is not the date and time of delivery to each medical institution. The reason is that in the embodiment, since reuse is also assumed, it is naturally possible that a medical device used in one medical institution is reused in another medical institution. That is, it is necessary to consider resale in order to calculate the residual value of the non-consumable part.

The parts DB has the structure shown in FIG. In the figure, the first column stores information indicating the type of medical device as a large classification, and the second category stores components of a medical device (system) that is a middle classification (for example, a gantry in the case of X-ray CT). , A transfer device, and an operation console), the third column shows information for identifying non-consumable parts and consumable parts, the fourth column shows the unit price of each part when new, and the last column shows the parts. Stores the calculation formula for the degree of wear. Actually, the subprogram corresponding to each calculation formula is separately stored, and the address of the subprogram and the information for specifying the argument when calling the subprogram are stored therein. become. It should be noted that the item "f0 (T)" in the wear level calculation formula is unique to the non-consumable product, and is calculated according to the attenuation curve formula shown in FIG. 11 as described above. It is calculated based on the elapsed time T (the period from the date and time of manufacture to the present) which is not notified from the medical institution. The degree of wear of other consumable parts can be calculated according to the parameters notified from the medical institution.

The system DB manages manufactured medical equipment and has a structure shown in FIG.

As shown in the figure, a system ID for identifying a medical device is used as a key for management, and an area 3200 for accumulatively adding a parameter notified from a medical institution for this system and an accumulative addition value are set. An area 320 for storing the calculation result of the degree of wear of each component based on
1, and the residual value of the system, the trade-in value, and
An area 3202 composed of the value when resold is provided.

The system residual value is the total value obtained by calculating the residual value of each component based on the calculation result (area 3201) of the degree of consumption of each consumable component shown in FIG. The trade-in value is a value obtained by multiplying the residual value by a predetermined value, and the resale value is a value obtained by adding a commission thereto.

When receiving an inquiry from each medical institution, the server 2000 is asked to input the ID of the medical period. As a result, the user DB can be accessed to determine what kind of medical device is installed in the medical institution. After that, based on this determination result, the system DB is searched using the system ID of each medical device as a key,
The trade-in price should be listed and notified. This notification method may be any method, but if one example is given, it is possible to connect to the Internet and run a browser.
Have C etc. installed in a medical institution and set server 2000 to W
It is to function as an eb server. Further, if the data collection device 3100 is constructed by a PC, it is not necessary to install new hardware in a medical institution, but in general, medical devices include a computer such as a personal computer.
b. Since there are one or two PCs that browse the website, it is possible to utilize them, so it is desirable to utilize them.

FIG. 13 shows an example of the display. Before reaching this display screen, the authentication process is performed by entering the user ID and password on the top homepage, and after this authentication, this screen is displayed (this H
Send the TML document to the client).

The management company can also extract and display the replacement time of consumable parts at each medical institution from the system DB. However, this display is displayed on the server 200
You can not browse on 0 or above.

FIG. 14 shows an example displayed on the display unit 2008. A column 3301 for inputting the degree of wear, a search (3
302) button 3302 for starting the operation, a column 33 for displaying a list of medical devices (for each medical institution) having components having a number equal to or higher than the value entered in the consumption level column 3301 when this search is performed.
03 is provided. A button 3304 for displaying the details thereof is provided in the area for displaying each search result. By clicking this button on the PD 2005, which component of the medical device (gantry, transport device, etc.) The details of whether the part is applicable are displayed (not shown).

Therefore, it is possible to sufficiently refer to the timing for performing maintenance such as replacement of consumable parts. When the component is replaced, the cumulative value in the parameter area 3200 in the system DB indicated by the system ID is cleared to zero.

The operation of the server 2000 is as described above, and its specific operation content will be described with reference to FIG.

FIG. 15 shows a processing procedure for receiving the operation status information notified from each medical institution.

First, in step S11, the reception of information from a medical institution is awaited. If received, the process proceeds to step S12, and it is determined whether the user is a legitimate registered user based on the user ID therein and the system ID. System ID
When the determination is made, in the next step S13, the system DB is searched using the system ID as a key, and the received data is added to the data in the parameter area 3200. Then, in step S14, the consumption level is calculated and updated according to the calculation formula of each consumable part based on the updated parameters, and in step S15, the system residual value, the trade-in value, and the resale value are calculated and updated. .

As a result of the above, each medical institution, for example, every week, reports the operating status of each medical device operated during that time to the server 2.
000, and the server 2000 can calculate the value of each medical device according to this notification. As described above, since the server 2000 calculates the value of the medical device when receiving the new operating status information, the value is eventually updated every week. In the embodiment, one week is taken as an example, but other days may be set. However, if it is performed every day, the load on the server 2000 increases, and the amount of money that falls per day is small relative to the overall value, so it is desirable that there be a certain number of days intervals as described above.

Next, the processing procedure (mainly search processing) relating to the operation of the server 2000 will be described with reference to the flowchart of FIG.

First, in step S21, a desired item is selected from an initial menu screen (not shown).

In step S22, it is determined whether or not the consumption level search is designated. If not, the process proceeds to step S23 and the corresponding process is performed.

As the processing in step S23, new medical institution registration or deletion work, medical device registration or deletion work in the medical institution, parameter replacement processing for parts when parts are replaced, owner transfer procedure (Resale procedure), disposal, etc.

When the consumption level search is designated,
Proceeding to step S24, the search window shown in FIG. 14 is displayed, and the consumption level is input in step S25 (default 0.9). Next, when it is determined in step S26 that the search button has been clicked, step S27
In step S28, the system DB is searched for a system including a component having a value equal to or higher than the input wear level, and the system is displayed in step S28. This display result is displayed as shown in the lower part of FIG. 14, as described above.

When the operator sees this screen and clicks the details button, the details are displayed. This display content has the same form as that shown in FIG. However, the parts that are equal to or higher than the input consumption level are displayed so as to be distinguished from the other parts (for example, displayed in red).

Next, a processing procedure when a browsing request is issued to the server 2000 from a PC installed in a medical institution will be described with reference to the flowchart of FIG. It is assumed here that the server 2000 functions as a Web server. Therefore, this flowchart is
It shall be started after the top home page is transferred from the client (here, the browser of the PC of the medical institution).

First, when a login request is made in step S31, the process proceeds to step S32, and the HTML document of the screen prompting the user to enter the user ID and password is sent to the client. As a result, the input result at the client and the user D are sent.
By collating with B, the authentication process of whether or not it is from the registered medical institution is performed.
