Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray CT system, and more particularly to an image taking method and a method of using a taken image in an industrial X-ray CT apparatus using an accelerator.

[0002]

2. Description of the Related Art Conventionally, a method of photographing an object by industrial X-ray CT and a method of using the photographed image are described in a literature (computer image processing: applied practice (Vol. 1): Hideyuki Tamura, edited by Research Institute) Publishing, pages 18-29 (199
0)). Needs include defect detection and size measurement inside the object, internal structure observation, internal density distribution measurement, and the like. In the conventional technology, a CT device is occupied and used, and a person who images a subject using a CT device and a person who needs a captured image are in the same or close communication situation. Is assumed.

[0003] In the field of medical X-ray CT in which a subject to be imaged is a human, segmentation of work is progressing, and a radiologist interprets an image taken by a radiologist, and a doctor diagnoses and treats using the result. It is starting to do. For this reason, Japanese Patent Application Laid-Open No. 7-275237 discloses a system in which an X-ray CT apparatus installed in a hospital and an image interpretation center are connected via a network so that an interpreting doctor at the image interpretation center can give an instruction on the imaging position of a patient in real time. It is proposed as follows.

In this system, a radiologist instructs the position of a cross-sectional image to be photographed by a radiologist based on a positioning image called a scanogram photographed with the patient fixed to the apparatus. Because the subject is a human, the positioning is simply fixed so that the patient is within the field of view of the device with as little movement as possible. Therefore, the relationship between the patient and the captured image is not strictly set. However, this point is not a problem in a medical X-ray CT apparatus. This is because both the photographing side and the diagnosing side who see the image are familiar with the internal structure of the human body, and it is only necessary to obtain information that can determine the difference from the normal internal body from the conventional knowledge.

On the other hand, in the industrial X-ray CT apparatus according to the present invention, the object to be imaged is an "object" and is usually a product manufactured by a human. Therefore, in many cases, the imaging client owns information inside the subject as numerical data.
For example, a design drawing of a subject, CAD data of a structural part, and material data of each part.

The information desired from the photographed image is a defect or the like different from the design conditions inside the product. Since it is desired to know in which part of the product the defect exists, it is very important to accurately know the positional relationship between the photographed image of the subject and the product as the subject. Since the tomographic image obtained when the subject is mounted on the scanner of the X-ray CT apparatus and photographed can be arbitrarily rotated on a computer, it can of course be roughly aligned. If the imaging client and the imaging person are the same, or if both have sufficient knowledge of the subject, it is expected that sufficient knowledge will still be obtained. However, an industrial X-ray CT apparatus often uses a high energy of X-rays and requires a radiation control area, so that considerable costs are required for new construction of a building or installation of a manager. That is, there is a problem that nobody can easily install and use the industrial X-ray CT apparatus.
For this reason, an industrial X-ray CT apparatus is installed in a certain place,
There is a need for a business that borrows a subject from a user (or a company) that needs a T image and takes an image.

In such an imaging business, the user has knowledge of the contents (dimensions, internal structure, materials, etc.) of the subject, but the imaging person has almost no such information. In addition, although the user can obtain the captured image, there is a problem that sufficient information on the detailed positional relationship between the image and the subject cannot be obtained.

[0008]

As described above, the industrial X
Since the X-ray CT apparatus requires a radiation control area, there is a problem in that it requires considerable expense such as new construction of a building and installation of a manager, and cannot be easily used by anyone.

Although a dedicated communication procedure can be used for the communication procedure, e-mails and WW
W is preferably used. The imaging control device 1 in the business entity receives the imaging request and adjusts the schedule. Specifically, information from the communication network 3 is received by the information terminal 5, and the operator of the information terminal 5 transmits the information to the storage device 6 via the computer 7.
The imaging schedule of the X-ray CT apparatus 8 recorded in the above is investigated (No. 1 in FIG. 2).

When the imaging schedule is adjusted, the information terminal 5 informs the customer 1 of the imaging schedule, secures an imaging number corresponding to the imaging of the subject of the customer 1, and records the schedule in the storage device 6 (No). .2,3). The customer 1 sends a detailed imaging requirement specification for subject imaging to the customer's information terminal 2

In addition, even when an information transfer request is made from a customer, data is output based on the photographing number, so that data of another customer is not leaked. Of course, it is needless to say that a password can be set or encrypted in order to further improve the security of the information.

As described above, according to the present embodiment, the user (customer) can request the test of the subject from the business entity by remote control, and the business entity can transmit the information such as the captured image to the specific user (customer). ) Only.

Another embodiment of the present invention will be described with reference to FIG. The present embodiment relates to a subject transport information control unit. In this system, in addition to the embodiment of FIG. 1, a transportation information terminal 16 and a storage device 17 are installed in a transportation company and connected to a communication network 3. The movement of the subject is always associated with the X-ray CT imaging business, and must be smoothly performed according to the imaging schedule. In the present embodiment, information on the movement of the subject is transmitted from the imaging control device 1 of the business entity to the transportation information terminal 16 of the transportation company at any time, so that the transportation company can transport the subject without delay. is there.

The operation of the present system will be described with reference to FIG.
This figure shows a procedure for exchanging information between the customer 1, the transportation company, and the business entity via the communication network 3.
When the customer 1 requests imaging of a subject, the information terminal 2 of the customer 1 is used to request the business entity to perform imaging. E-mail and WWW via the communication network 3 are used for this communication procedure. Of course, a unique communication procedure may be used. The imaging control device 1 in the business entity receives the imaging request and adjusts the schedule. Specifically, information from the communication network 3 is received by the information terminal 5, and the operator of the information terminal 5 investigates the imaging schedule of the X-ray CT device 8 recorded in the storage device 6 via the computer 7 (FIG. No. 1 in No. 4).

The transportation company accepts the transportation request from the business entity at the transportation information terminal 16 and stores the transportation schedule in the storage device 17. The customer 1 transmits detailed imaging requirement specifications for subject imaging from the information terminal 2 of the customer to the information terminal 5 of the business entity, and the business entity associates the received requirement specification with the corresponding reception number and stores it in the storage device 6. (No. 5). The X-ray CT photographer confirms the photographing position of the subject by using the information terminal 5 and viewing the photographing required specifications stored in the storage device 6 (No. 6).

When the transportation company approaches the date and time of transportation of the subject,
The transport information of the subject is transmitted from the transport information terminal 16 to the information terminal 2 and the imaging control device 1 (No. 7). In response to this, the customer 1 prepares for carrying out the subject according to the schedule, and the business entity carries out preparation for carrying in the subject. In actual transportation, a transportation means 12, for example, a truck is arranged at the customer's place from the transportation company, and the subject is transported to the business entity through the transportation route 13. The transportation contact information is recorded by the computer 7 through the information terminal 5 in the imaging schedule database stored in the storage device 6. The photographer prepares for photographing by checking the photographing schedule database using the information terminal 5 (No. 8). When the subject arrives at the business entity, the photographer places the subject on the X-ray CT apparatus 8 and takes a cross-sectional image (No. 8). The photographed cross-sectional image data is read from the X-ray CT apparatus 8 by the computer 7 and stored in the storage device 6 in association with the photographing number (N
o.10). The operator reads the photographed image data from the storage device 6 using the information terminal 5, and reads out the information terminal 2 of the customer 1.

o.11). Further, the photographing data can be stored in the storage device 4. The transportation company transmits a subject return notification from the transportation information terminal 16 to the information terminal 2 of the customer 1 and the imaging control device 1 of the business entity based on the transportation schedule stored in the storage device 17. In actual transportation, the subject is transported from the business entity to the customer 1 via the transportation route 14 by the transportation means 12. As described above, according to the present embodiment, the subject can be efficiently transported.

Further, another embodiment will be described with reference to FIG. In this embodiment, in addition to the configuration of the embodiment of FIG.
The device 8 is provided with a setting device 18.
In an X-ray CT utilization system, various subjects are brought in from a customer. Therefore, the subject cannot always be easily installed on the X-ray CT apparatus 8. An X-ray CT apparatus is usually equipped with a scanner that rotates with a subject mounted thereon, and its surface is flat. If the subject is placed on a flat surface, it is stable. If the required imaging section is parallel to the scanner surface, the subject may be left on the scanner as it is, but it is expected that it may not be. The present embodiment has been made in view of the above, and is provided with a device on the scanner that can set the subject by changing the direction and position of the subject on the scanner. The setting device may be any device that can hold the subject and can change the position and orientation of the subject. For example, it can be realized by an apparatus in which a holder for a subject is attached to an XY stage with a ball pivot. Changing the axial direction of the subject can be realized by setting a ball pivot at the center of the scan and attaching a holder to the ball pivot. According to the present embodiment, the direction and position of the subject can be freely changed on the scanner, so that an arbitrary imaging section can be obtained.

FIG. 6 shows an embodiment which makes the invention of FIG. 5 more concrete. The figure shows an X-ray CT apparatus 8 and a setting apparatus 1
The configuration of only part 8 is shown in detail. Conventional X-ray C
The T device 8 includes an electron beam accelerator 21 for outputting an X-ray fan beam 22, a scanner 23 for installing the subject 9, and a scanner 2.
A vertical driving device 24 for moving the specimen 3 vertically, and a collimator 2 for improving the S / N of X-rays transmitted through the subject 9.
6, an X-ray sensor 27 for measuring X-rays transmitted through the subject 9, a signal processing circuit 28 for amplifying a signal from the X-ray sensor 27 and converting it to a digital value, and receiving a signal from the signal processing circuit 28 X-ray CT controller 3 for controlling electron beam accelerator 21, scanner 23, vertical drive unit 24
1, an image reconstruction computer 33 that reconstructs a radiographed cross-sectional image using radiographing data from the X-ray CT controller 31 and an image terminal 34 for displaying the radiographed cross-sectional image. The X-ray CT apparatus 8 in the figure is a third-generation X-ray CT apparatus that takes one section by simply rotating the subject. When using a second-generation X-ray CT apparatus that performs imaging by combining rotation and translation of the subject (moves in a direction perpendicular to the direction of the accelerator / sensor), a translation movement mechanism is further required. Further, in the case where it is also used for photographing a transmission image by digital radiography, a translation movement mechanism may be provided even in the case of the third generation.

X-ray CT controller 31 and electron beam accelerator 2
1, a scanner 23 and a vertical drive 24 are connected to a control cable 3.
Under the control of the X-ray CT controller 31, generation of an X-ray fan beam, rotation of the scanner, and adjustment of the vertical position of the scanner are performed. The X-ray sensor 27 has a large number of X-ray sensors arranged in a line. In this embodiment, 512 semiconductor radiation sensors are used. Of course, the number of sensors is at least better, but it goes without saying that the greater the number, the more convenient the shooting. X-ray C
The T controller 31 and the image reconstruction computer 33 are connected via a signal cable 32, and the image reconstruction computer 33
Image reconstruction is performed using the sensor data received from the line CT controller 31 to create a cross-sectional image. The cross-sectional image data can be viewed by the image terminal 34 and a signal cable 35
To the computer 7 and finally stored in the storage device 6.

In the present invention, the setting device 18, the linear driving device 36, and the linear driving rail 37 are installed in the conventional X-ray CT device 8. The setting device 18 is installed on the scanner 23 and can change and fix the position and direction of the subject 9. The structure of the setting device 18 will be described later. The linear drive device 36 is a linear drive rail 3
7, the vertical drive unit 24 and the scanner 2 mounted
3. The setting device 18 can be moved in the direction of the electron beam accelerator 21 ← → collimator 26. When the subject 9 is moved closer to the electron beam accelerator 21, the size of the subject that can be imaged is reduced, but the imaging resolution is improved. Conversely, when the X-ray fan beam 22 is closer to the collimator 26, the width of the X-ray fan beam 22 increases, so that a large cross section of the subject can be imaged. By providing the linear driving device 36 and the linear driving rail 37 in this manner, the position of the subject can be changed according to the size of the subject and the required resolution.

FIG. 7 shows the structure of the setting device 18. The setting device 18 is fixed to the scanner 23 by the setting device gantry 40, and a subject driving table 42 is provided on the setting device gantry 40.
2 is driven by a drive motor 41 so that the inclination can be changed. The drive motor 41 is controlled by a motor control circuit 38.
The angle formed by the subject driving table 42 with the setting device base 40 is measured by a built-in encoder, and the encoder control circuit 39 obtains angle information. The control of the motor control circuit 38 and the information input of the encoder control circuit 39 are X
This is performed using the line CT controller 31. FIG. 3 shows a state in which the subject driving base 42 is inclined by 10 degrees. The subject fixtures 43 and 44 are jigs for fixing the position of the subject.

By adopting such a structure, it becomes possible to image a subject in an oblique section. Also, by sending the customer's required specifications stored in the storage device 6 to the X-ray CT control device 31 via the computer 7 and the image reconstruction computer 33, the X-ray CT control device 31 The subject drive base 42 can be automatically controlled based on information from the encoder control circuit 39 and can be set to a desired angle. Needless to say, in this embodiment, since the rotation axis of the object driving table 42 is one, the direction of the object cannot be arbitrarily changed. To change it arbitrarily, it is necessary to add one more axis. However, actually, the subject is fixed to the subject fixtures 43 and 44.
In the case of fixing by using, since the direction of the subject can be changed, a sufficient effect can be obtained even with one axis.

FIG. 8 shows an elevational view and a plan view of the setting device 18. The subject fixtures 43 and 44 can move along fixture moving grooves 45 and 46 and can be fixed to the subject drive base 42 with bolts. A reference line 47 is provided on the side near the collimator 26, and by measuring the distance from this line to the subject fixture 44, the initial position of the subject can be recorded. Linear drive 36
The X-ray CT controller 31 has a drive motor and a positioning encoder circuit similarly to the setting device 18.
Can be controlled by the setting device 18
Since it can be realized with the same circuit configuration as in the case of (1), the drawing is omitted.

As described above, according to the present embodiment, the subject is subjected to X-ray imaging by the imaging control device based on the user's imaging requirement specifications.
It can be moved and positioned automatically on the scanner of the line CT apparatus.

Further, in addition to the present embodiment, a laser distance measuring device which moves along the collimator 26 is attached,
Can be further rotated up and down, scanned by a laser, and the initial position of the subject 9 can be determined by measuring the distance from the collimator 26 to the subject 9.

Further, a three-dimensional shape measuring device using a laser and a CCD camera is installed on the scanner side, and the subject 9 is rotated by the scanner 23 to irradiate the laser, and the position on the scanner and the external dimensions of the subject are measured. It can also be measured. By doing so, there is an effect that information on the inside and outside of the subject 9 can be integrated in correspondence with the cross-sectional image of the subject 9 measured by the X-ray CT apparatus 8.

FIG. 9 shows another embodiment of the setting device. The subject has various shapes to be carried by the customer. Therefore, it is conceivable that the customer can prepare an attachment to the subject in advance. FIG. 9 shows an embodiment in which an electric motor is used as the subject 9 for imaging. The subject fixing table 48 as an attachment fixes the subject 9 upright in accordance with the imaging requirements of the customer. Subject fixtures 49 and 5
0 is created in accordance with the subject 9, and the subject 9 is fixed with fixing bolts 53. The scanner 2 is mounted on the subject fixing table 48.
A fixing hole 52 is formed so as to be connected to the fixing pin 51 on the upper part 3. By using such an attachment, the subject 9 can be positioned on the scanner 23 of the X-ray CT apparatus 8 without adjustment. In addition, there is an advantage that the setting time is reduced and the possibility of setting errors is reduced by fixing the subject 9 to the subject fixing table 48 in advance and bringing it from the customer to the business entity. As described above, in this embodiment, it is possible to perform positioning with a simple tool.

Another embodiment will be described with reference to FIG. Also in this embodiment, the information terminal 2 of the customer 1 and the photographing control device 1 of the business entity are connected by the communication network 3. Needless to say, the number of customers may be plural, but is not omitted in this figure. The basic operation of this embodiment is the same as that of the first embodiment shown in FIG. For industrial products, there are usually design drawings, and at present, they are usually stored in a database as two-dimensional or three-dimensional CAD data. Therefore, the customer 1 stores the design data of the subject in the database 60 in the company. When a business entity is requested to perform cross-sectional imaging by X-ray CT using the present system, not only is the photographed image required specification data 62 prepared in the storage device 4, but also the subject is read from the database 60 via the in-house network 61. The design information data 63 can be prepared by preparing the design information data 63 by extracting the design data 9. Therefore, the information terminal 2 transmits the design information data 63 together with the photographed image required specification data 62 when transmitting the photographed required specification to the photographing control device 1 (No. 4 in FIG. 2).
The photographing control device 1 receives the photographed image required specification data 62 and the design information data 63 by the information terminal 5 and stores them in the storage device 6 as the photographed image required specification data 64 and the design information data 65, respectively.

The photographed image required specification data 64 describes, for example, a photographing start position, a photographing pitch, the number of photographing cross sections, and a photographing direction. The design information data 65 may be the design data itself stored in the database 60,
Usually, only the minimum data necessary for shooting is transmitted from the customer to the business entity. For example, external dimensions of the subject, two-dimensional or three-dimensional data of internal components, and the like. The captured image data 66 is a set of cross-sectional images of the subject captured by the X-ray CT apparatus 8 based on the required image data 64. In order for the operator to obtain the photographed image information at the information terminal 5, the photographed image management program 67 operates in the computer 7, and the photographed image required specification data 64 and the design information data 6
5, and display data is created using the information of the captured image data 66. The details will be described later.

In FIG. 10, the subject 9 (an electric motor is illustrated in this drawing) is a state in which the subject is previously installed on an attachment (comprising the subject fixing table 48 and the subject fixing tools 49 and 50). And transported to the business entity. Of course, the business entity may attach the attachment. Further, the X-ray CT apparatus 8 may include a setting device 18 as shown in FIG.

FIG. 11 shows the relationship between the information stored in the storage device 6. In this figure, information such as a shooting schedule is omitted. All information on the subject is stored in association with the imaging number 68 determined at the time of receiving the imaging request. Information related to one subject is customer information 69,
These are photographed image required specification data 64, design information data 65, and photographed image data 66. The data of the photographed image data 66 is a plurality of photographed image data 7 which are cross-sectional images of the subject.
0 (of course, this includes a data number) and a position information data section 71 associated therewith.

FIG. 12 is a flowchart showing the operation of the photographed image management program 67. The operator operates the information terminal 5
, The photographed image management program 67 starts operation (program execution contents 81), and if the transfer of the image from the X-ray CT apparatus 8 has not been completed (program execution contents 82), the corresponding photographed image data From the X-ray CT apparatus 8 (program execution contents 83). X-ray C
The image data received from the T device 8 is photographed based on the photographed image required specification, but is not associated with the design information of the subject.

Therefore, in the present program, a data number is assigned to each photographed image data, and a position information data section 71 is added based on information obtained from the photographed image required specification data 64 and the design information data 65 (program execution contents 8
4) Store the captured image data 66 in the storage device 6 in association with the shooting number 68 (program execution content 8)
5). After this processing is completed, when the operator makes a display request, the photographed image is displayed on the CRT of the information terminal 5 together with the photographing number, customer name, data number, and positional information data (program execution contents 86). Since the position and the imaging pitch of the subject at the start of the imaging are clear according to the imaging specification, if the design information data 65 is used, not only the position of the imaging section from the bottom surface of the object but also the specific information Information such as the part can also be entered.

FIG. 13 shows an example in which photographed image data is displayed on the CRT 91 of the information terminal 5.

The requested photographed image 96 is displayed on the CRT 91. In the present embodiment, since each photographed image data is associated with various information by the photographed image management program 67, the number display section 93 at the upper left of the display screen is displayed.
Indicates the customer name, the photographing number and the data number, and the position information display section 94 at the upper right indicates the position of the displayed photographed image.
The specific position of the subject (in this drawing, the height from the bottom surface or the height from the bearing surface of the motor) can be displayed. At the same time, position coordinates 95 and direction display 97 indicating the installation position of the subject on the attachment are shown on the screen. In the present embodiment, since the subject is installed on the attachment in advance from the customer side, information indicating the installation position is included in the photographed image required specification data 64 in advance. If the embodiment shown in FIG. 6 is applied to an X-ray CT apparatus,
It can be obtained from the line CT apparatus 8.

If the imaging control apparatus 1 is configured as described above, the captured image data can be utilized not only as a photograph but also as information closely corresponding to the design information of the subject, and the design information (design drawing ) Can easily display a cross-sectional image at a position quantitatively designated from the above.

In the above description, the case where the photographed data is displayed on the information terminal 5 on the side of the business entity has been described. Of course, the customer accesses the photographing control device 1 using the information terminal 2 and executes the photographed image management program 67. You can see a similar image by moving it. The captured image data 66 is transferred to the storage device 4 on the customer side via the communication network 3. Therefore, the same photographed image display can be viewed on the customer side using the information terminal 2, and the photographed image data 66 can be freely processed and used by using an original program.

An embodiment in which new functions are added to the embodiment of FIG. 10 is shown. The flowchart shown in FIG. 14 is obtained by adding a function of creating a cross-sectional view of a part from the design information data 65 to the photographed image management program 67 shown in the embodiment of FIG. It is. That is, when the operator inputs the position information of the image desired to be viewed from the information terminal 5 on the subject, the photographed image management program 67 creates a sectional view of the subject at the corresponding position using the design information data 65 (program Execution contents 87). The design information data 65 stores the design information of the subject transmitted from the customer. For example, when three-dimensional CAD data is stored, a cross-sectional view at that position can be easily created if the cross-sectional position of the subject is determined. In addition, if one of a plurality of components on the cross section is designated, it can be extracted. Next, the photographed image data corresponding to the photographing position is extracted from the photographed image data 66 (program execution contents 88), and the created cross-sectional view and photographed image of the subject together with the photographing number, customer name, data number, and positional information data are obtained. The information is superimposed and displayed on the CRT 91 (program execution contents 89). If only one part is designated, the other part can be erased and displayed.

FIG. 15 shows an example of a display result on the CRT 91 of the information terminal 5 according to the embodiment of the present invention. The position information display section 94 displays the position information of the cross section of the desired part. The part cross-sectional view 99 is a cross-sectional view of the part (rotor) created by the program execution contents 87, and is displayed so as to overlap the photographed cross-sectional image. By displaying in this manner, it is possible to easily display where the positions of the internal defects 100 and 101 are located in the actual part. In addition, the difference between the dimensions and the like can be easily measured from the deviation between the design sectional view and the photographed image. Dimension measurement on a display screen using a cursor or the like can be handled by conventional techniques.

As described above, according to the present embodiment, the cross-sectional view of the part for which the design information has been obtained can be superimposed on the photographed image, and the internal defect found by the photographing can be displayed on the actual part. There is an effect that the position can be easily displayed.

The embodiment described above mainly relates to a photographing business for photographing an internal section of an industrial product. On the other hand, in the X-ray CT imaging business, there is also a need to know the dimensions and the internal structure of an article that has no design drawing and an unknown internal structure, such as a buried object or an antique object. FIG.
The embodiment of the present invention provides an X-ray CT utilizing system useful in such a case. Although the entire configuration conforms to FIG. 1, only one information terminal 2 is illustrated. Of course, it is the same even if there are plural units.

Since there is no design information for the subject which is the object of this embodiment, the information prepared by the customer is only the photographed image required specification data 62. The outline of the operation between the customer and the business entity is the same as in FIG. When the imaging schedule is determined and the subject 9 is sent from the customer to the business entity, the X-ray CT apparatus 8
Is used to take a picture of the cross section. In the case of an industrial product, the position information could be added to the imaging screen using the design information, but in the case of the present embodiment, the subject does not have such information. Therefore, there is a problem that there is no position information data indicating the relationship between the photographed image and the subject necessary when the customer views the photographed data. In this embodiment, to solve it,
Data in which the position and direction of the subject on the scanner at the time of imaging are recorded are stored in the storage device 6 as subject imaging position data 111. Further, position information based on the subject imaging position data 111 is added to the captured image so that the captured image data 1
12 is created. These operations are executed by the photographed image management / position determination program 113 of the computer 7.

FIG. 17 is a flowchart showing the execution contents of the photographed image management / position determination program 113. When there is a display request of imaging data from the information terminal 5 (program execution content 121), if the imaging image data is not completed, first, the installation position and direction of the object on the scanner are used as data to obtain the imaging position of the object. It is stored in the data 111 (program execution contents 123). Usually, in order to set the subject at the center of the scanner, if the bottom of the subject is marked in advance and aligned with the center axis of the scanner, the information may be stored. Next, a captured image is captured from the X-ray CT apparatus 8 (program execution contents 12
4), subject imaging position data 11 for each captured image
Based on the information stored in the image data 1 and the information such as the shooting pitch stored in the shot image request specification data 64, position information data is added (program execution content 125) and stored in the storage device 6 as shot image data 112. (Program execution contents 126). The subject photographing position data 111 and the photographed image data 112 together with the photographed image required specification data 64 are
In the same manner as in the first embodiment, the information is stored in association with the imaging number corresponding to the subject. When the photographing data is completed in this way, an image is displayed based on an input instruction from the information terminal 5 (program execution content 127).

FIG. 18 is an example of a photographed image of the subject displayed on the CRT 91 of the information terminal 5. In this example, the image of the photographed image 117 is included in the photographed image 116 as a cross-sectional image. The subject is placed so that the points A and B on the bottom surface, which are marked in advance, are aligned with the central axis of the top surface of the scanner. On this screen, a scanner center axis display 115 is displayed. The position information display unit 114 indicates that this image is a screen having a height of 2 mm from the bottom surface of the subject (that is, the surface of the scanner). Further, the number display section 93 displays an imaging number unique to the subject and a data number unique to the captured image as in FIGS. 13 and 15.

The photographed image is started and operated by the photographed image management / position determination program 113 remotely from the information terminal 2 via the communication network 3, and the display C of the information terminal 2 is displayed.
Needless to say, it can be displayed on the RT. In addition, since the subject imaging position data 111 and the imaging image data 112 can be transferred to the storage device 4, the imaging image can be used by a program on the customer side. Since the positional relationship between the subject and the captured image is clear, the captured data can be effectively used even when a part of the subject is cut in order to confirm the internal structure of the subject. In addition, even when a detailed cross-sectional image is captured again, the subject can be accurately set at the same position as the previous image.

As described above, according to this embodiment, since the positional relationship between the subject and the photographed image can be clarified, the photographed image of the subject without design information is associated with the actual position of the subject at the time of photographing. There is an effect that can be converted into numerical data.

Further, a three-dimensional shape measuring device using a laser and a CCD camera is installed on the side of the scanner, and the object 9 is rotated by the scanner 23 to irradiate the laser, and the position on the scanner and the external dimensions of the object are measured. It can also be measured. By doing so, there is an effect that information on the inside and outside of the subject 9 can be integrated in correspondence with the cross-sectional image of the subject 9 measured by the X-ray CT apparatus 8.

Further, it is also possible to connect the stereolithography apparatus to the photographing control apparatus 1 and control the stereolithography apparatus by using the obtained photographed image data 112 as data for making a copy. The stereolithography apparatus has the effect of creating a copy that reproduces not only the outer surface of the subject but also the internal structure. In other words, not only the outer shape but also the inside can be produced as a replica of the genuine article, which can be utilized greatly in academic research.

FIG. 19 shows still another embodiment. This embodiment is obtained by adding a function of extracting a part constituting a subject in addition to the embodiment of FIG. That is, instead of the photographed image management / position determination program 113, a photographed image management / parts extraction program 132 is provided in the computer 7, and the photographed image required specification data 64, the subject photographing position data 111,
Further, shape data of each component (or a structure having a different density) constituting the object is extracted using the captured image data 112 and stored in the component data 131. FIG. 20 is a photographed image management / parts extraction program 1
32 is a flowchart showing an execution content of No. 32. When there is a display request of imaging data from the information terminal 5 (program execution content 121), if the imaging image data is not completed, first, the installation position and direction of the object on the scanner are used as data to obtain the imaging position of the object. It is stored in the data 111 (program execution contents 123). Usually, in order to set the subject at the center of the scanner, if the bottom of the subject is marked in advance and aligned with the center axis of the scanner, the information may be stored. Next, the captured image is converted to an X-ray CT
Captured from the device 8 (program execution content 124), for each captured image, based on the information stored in the subject imaging position data 111 and the imaging pitch and the like stored in the captured image required specification data 64, The position information data is added and stored as the photographed image data 112 in the storage device 6 (program execution content 125). The subject photographing position data 111 and the photographed image data 112 are stored together with the photographed image required specification data 64 in association with the photographing number corresponding to the subject as in the embodiment of FIG. Next, X-ray C
Since the image data of T inherently has density information,
From the cross-sectional image of the captured image data 112, it is possible to extract the components constituting the subject. Since a plurality of photographed cross-sectional images are photographed in the vertical direction, continuous portions of the same density portion can be recognized as one object. An object can also be cut out by extracting the contour of the same density portion by image processing and tracking the contour continuously in the vertical direction. In this way, the structural parts of the subject are extracted (program execution contents 128), the structural parts are numbered, and stored as numerical data as the part data 131 in the storage device 6. The data format is a 3D CAD data format such as a solid model. When the photographing data is completed in this way, an image can be displayed based on an input instruction from the information terminal 5 (program execution content 127), or an extracted component can be displayed using the component data 131. (Program execution contents 130).

FIG. 21 shows a display example on the CRT 91 of the information terminal 5 in this embodiment. The part number display section 118 displays the number of the displayed part. The scanner central axis display 119 displays the central axis of the scanner, and corresponds to the coordinate axes of the data of the subject and the extracted object. The extracted parts are three-dimensionally displayed as in the part display 120. Since the extracted parts are stored in the form of CAD data and stored, it goes without saying that two-dimensional cross-sections can be displayed. The component data 131 is stored in the storage device 4.
The data can also be transferred to the customer, so that the data can be used in the customer's program. Since the positional relationship between the subject and the photographed image and the extracted parts is clear, it can be used not only for analysis of buried objects and antiques, but also for re-engineering of industrial products.

Also in this embodiment, the stereolithography apparatus is connected to the photographing control device 1 to obtain the photographed image data 1.
It is also possible to control the optical shaping apparatus by using 12 as data for making a copy. The stereolithography apparatus has the effect of creating a copy that reproduces not only the outer surface of the subject but also the internal structure. Further, if the color is changed for each part of the replica to be created based on the density information, it can be used as a structural model. That is, not only the outer shape but also the inside can be produced as a replica of the real thing, which is very effective in academic research.

As described above, according to this embodiment, X
Numerical data of the shape of the component constituting the subject can be determined from the image captured by the X-ray CT apparatus, and user convenience can be achieved.
