Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angio device, an operation console and a control method thereof.

[0002]

2. Description of the Related Art Conventionally, there is known an angio apparatus for obtaining an image (angiography) which characterizes a region through which a blood vessel of a subject passes through by imaging. The geometrical feature of this apparatus is that an X-ray tube and an image intensifier that detects X-rays that have been exposed from the X-ray tube and that have passed through the subject and acquire it as image information (hereinafter,
I. I) or flat panel detectors (hereinafter referred to as FPDs) are provided at both ends of the C-arm, and the C-arm is rotated at a desired angle, so that a transmission two-dimensional X-ray image in virtually any direction can be obtained. It can be said that there is a point that can be obtained.

The purpose of the angio apparatus is to obtain a two-dimensional X-ray image of the subject as described above.
An angio CT system combining gantry used in a line CT apparatus is also known.

The advantages of constructing the angio CT system are that space can be saved as compared with the case where each is installed in an independent room, and a transport device for lying and transporting the subject can be shared. It is a cost advantage. Further, it is often the case that a contrast agent is injected into a subject by an angio apparatus, and then a scan is performed by an X-ray CT apparatus to obtain a tomographic image of a diseased part of the subject, but because it is in the same room, There is also a point that the shift can be performed in a short time and the burden on the subject, that is, the patient can be reduced.

[0005]

However, even if the space can be saved, the gantry and the angio apparatus are installed in the same room, and there is a limit to the space saving. Further, as is well known, the angio apparatus is provided with a rotation mechanism with two or three axes. Therefore, in order to prevent the rotation of the angio apparatus from colliding with the gantry, the gantry should be kept in a safe position during use. A space to save is required.

The inventors of the present application have paid attention to such problems,
It is an object of the present invention to provide an angio apparatus that does not require a gantry, can reconstruct a simple X-ray tomographic image with the angio apparatus alone, and can achieve low cost and further space saving.

[0007]

In order to solve such a problem, for example, an angio apparatus of the present invention has the following configuration. That is, an angio apparatus comprising a C-arm, an X-ray tube provided near both ends of the C-arm, and a detector for detecting an X-ray emitted from the X-ray tube on a secondary plane,
The C-arm has a perfect circular arc shape, the X-ray tube and the detector are provided at positions facing each other with respect to the center of the C-arm, and the C-arm is slidably held along the circumference. And a drive unit that slides the C arm held by the holding unit.

An angio apparatus of another invention has the following configuration. That is, an X-ray tube and a detection unit for detecting X-rays emitted from the X-ray tube on a secondary plane are held at both ends,
An angio apparatus comprising an arm having an opening for maintaining a space between the X-ray tube and the detection unit, wherein a holding unit for holding a central position of the arm and a rotation shaft for the holding unit. And a rotation drive unit configured to rotate the X-ray tube and the detection unit around the rotation axis, the extension direction of the rotation shaft in the axial direction passing on a line connecting the X-ray tube and the detection unit. .

[0009]

DETAILED DESCRIPTION OF THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

First, a scan for obtaining an X-ray tomographic image in the X-ray CT apparatus will be briefly described, and then,
The angio apparatus according to this embodiment will be described.

FIG. 6 is a diagram schematically showing the operation related to the scanning of the gantry of the X-ray CT apparatus.

It is assumed that there is an X-ray tube at point A in the figure. The exposure range (fan angle) θ of the X-ray tube is limited by a known collimator mechanism. Therefore, when the X-ray tube is located at point A in the figure,
During the period indicated by the line segment P and the line segment Q, in other words, the range of the point BC is irradiated with the X-ray.

Now, an X-ray tube exists at point A, and from that position, it rotates about point O in the direction of arrow a in the figure, and
It is assumed that the X-ray tube is located at the point. The exposure range at this time is between points A and D. It should be noted here that one of the exposure boundaries when the X-ray tube is located at the point B is the line segment P. That is, when the X-ray tube rotates to the point B, the exposure in the direction opposite to the exposure boundary line P when the X-ray tube is at the position A starts to be started.

After that, when the X-ray tube rotates in the direction of the arrow a and reaches the point C, one of the boundaries of the exposure range becomes the line segment Q shown in the figure. This line segment Q becomes the other exposure boundary when the X-ray tube is located at the point A.

In short, regarding the exposure range when the X-ray tube is present at the point A, the exposure from the opposite direction (180 °) is performed until the point B to the position C. Means to be seen. That is, in the case of FIG. 6, the X-ray tube needs to be rotated by at least θ _w (= π + θ) turns.

To reconstruct an X-ray tomographic image, sufficient transmission X-ray data is required for the area to be reconstructed. The area commonly exposed at each rotation position of the X-ray tube is also an area inscribed in the exposure range at each rotation position of the X-ray tube. That is, in CT, the illustrated F
The X-ray tomographic image can be reconstructed in the OV (Field Of View). Since the reconstruction process itself is performed by a known calculation, its description is omitted.

The scanning in the X-ray CT has been briefly described above, but in order to obtain higher accuracy, it is necessary to further rotate from the point B to the point A to the point E. As a result, transmission X-ray data in all directions can be obtained within the illustrated FOV, and a highly accurate X-ray tomographic image can be obtained. This scan is commonly called a full scan,
Scanning performed by less than one rotation between points A and B described above is called half scanning.

<Description of Device Configuration and Operation in Embodiment> FIG. 1 is an external view of the angio system in the embodiment. The angio system includes an angio device 100, a transport device 200 for mounting and transporting a subject, and a monitor (usually suspended from the ceiling) that displays a two-dimensional image that has been photographed (not shown). It will be. In the angio system of the embodiment, an operation console for setting the above-mentioned purpose, that is, a scan plan for reconstructing an X-ray tomographic image and the like is separately provided.

The angio apparatus 100 comprises a base support 1,
A C-shaped arm 3 for holding an L-shaped support portion 2, an X-ray tube 10 and a flat panel detector 11 which are rotatably attached to a base support 1 along arrow A in the vicinity of both ends.
(Hereinafter, simply referred to as “C arm”), and a C arm holding unit 4 that holds the C arm 3, slides in the direction of arrow B in the drawing, and is rotatably attached along the arrow C in the drawing. Note that guide grooves 3a are provided on both side surfaces of the C arm 3 so that the C arm holding portion 4 can easily hold the C arm 3.

Here, as a means for detecting the exposed X-rays, I.D. Not I (Image Intensifier)
The FPD (flat panel detector) is used because the latter has higher resolution than the former and also has a higher S / N ratio, and accuracy close to that of an X-ray detector in X-ray CT can be obtained.

FIG. 2 is a diagram schematically showing the structures of the C arm 3 and the C arm holding portion 4.

The C arm 3 in the embodiment has a shape of a true arc, and the center O of the C arm 3 is located on the line connecting the focal point X of the X-ray tube 10 and the center of the FPD 11. ing. In other words, the X-ray tube 10 and the FPD 1
1 is provided at a position facing each other by 180 ° with the center O of the C arm 3 interposed therebetween.

In addition, the C-arm holding portion 4 includes the C-arm 3
A drive unit 4a including a gear that meshes with a gear 3c provided on the outer periphery of the motor and a motor is provided. By driving this drive unit 4a, it is possible to rotate the C arm 3 in the direction of the arrow B shown in the figure (which is also the B direction in FIG. 1).

Therefore, by driving the driving unit 4a, the X-ray tube 10 and the FPD 11 move 180 degrees with respect to the center O.
Rotating around the center O while maintaining the facing positional relationship. This is equivalent to the scan operation by the gantry in the X-ray CT apparatus described in FIG.

However, as described with reference to FIG. 6, the range of rotation needs to exceed 180 °. Strictly speaking, when the exposure fan angle θ ′ of the X-ray tube in FIG. 2 is set, it must be able to rotate about (π + θ ′). In order to achieve such an object, in order to secure this θ ′ amount at the end portion of the C arm 3 on the X-ray tube 10 side in the embodiment, as shown in FIGS. 1 and 2, it extends along the circumference. The extension 3b is provided.

Actually, scanning for obtaining an X-ray tomographic image will be described with reference to FIG.

First, by driving the driving portion 4a of the C-arm holding portion 4, the end portion on the FPD 11 side is moved to the C-arm holding portion 4.
To hold. This state is shown in FIG.
It is (a).

After the above state, the X-ray tube 10 is driven,
The acquisition of the transmitted X-ray data by the FPD 11 is started, and the C arm 3 is rotated in the direction of the arrow D in the drawing (which is realized by driving the driving unit 4a of the C arm holding unit 4).

In order to obtain an X-ray tomographic image, the X-ray exposure range shown in FIG.
As described above, it is sufficient to move the wire tube 10. The state at this time is as shown in FIG. That is, the rotation may be performed until the boundary 31 of the X-ray irradiation range in the state of FIG. 3B and the boundary 30 of FIG.

As a result of the above, the data from the FPD 11 obtained from the same figure (a) to the same figure (b) shows that the X-ray tube turns from point A to point C in FIG. The data is equivalent to the data obtained up to that point, and the X-ray tomographic image can be easily reconstructed.

In the above example, the FPD is set as the initial position.
Although the C arm holding portion 4 holds the end portion on the 11th side, the C arm holding portion 4 may hold the end portion on the X-ray tube side.

Further, at present, since the length of one side of the detection surface of the FPD 11 is shorter than the length of the X-ray detector in the X-ray CT, the fan angle θ'in the angio apparatus is reduced.
Is smaller than the fan angle θ in the gantry of X-ray CT. As a result, the area FOV capable of reconstructing the X-ray tomographic image in the embodiment is inevitably smaller than the FOV in the X-ray CT, but it is also possible to make the FPD larger, so that a wider FOV is obtained. It will be possible to secure it.

Now, the angio apparatus 10 in the embodiment.
In order to obtain an X-ray tomographic image using 0, as in a normal X-ray CT apparatus, a scan plan (for example, slice thickness of the X-ray tomographic image and its interval, and a scanning range) is set, Is provided.

FIG. 4 shows the configuration of the operation console 300.

The operation console 300 is a so-called workstation, and as shown in the figure, a CPU 60 that controls the entire apparatus, a ROM 61 that stores a boot program and a BIOS, and a RAM 62 that functions as a main storage device.
The following configuration is provided.

The HDD 63 is a hard disk device, in which the OS, the angio device 100 and the transfer device 200 are installed.
And a diagnostic program for reconstructing an X-ray tomographic image based on data received from the angio apparatus 100 in the CT mode.
Reference numeral 64 is an input device such as a keyboard and a mouse. 65
Is an interface for communicating with the angio apparatus 100 and the transport apparatus 200. Reference numeral 66 denotes a display control unit, which is internally provided with a memory for developing image data to be displayed on the display device 67. A screen for setting various scan plans and a reconstructed image are displayed on the display device 67.

The processing procedure for obtaining an X-ray tomographic image using the operation console 300 will be described below.

First, in step S11, a scan plan is set. When this setting is completed and a scan start instruction is issued, the process proceeds to step S12, and the C arm 3 is moved to the position shown in FIG.
Rotate to the position shown in (a).

Thus, when the preparation for the scan is completed, the driving of the X-ray tube 10 is started and the rotation of the C arm 3 (the driving of the driving unit 4a of the C arm holding unit 4) is started in Steps S14 and S15. Start.

As a result, since the transmitted X-ray data is transferred from the angio apparatus 100 to the operation console 300, it is received via the interface 65 and the HD
The data is sequentially stored in D63. This storage is performed in step S1.
In step 7, the process is repeated until it is determined that the C arm 3 is in the state shown in FIG.

In the state shown in FIG. 3B, that is, when the scan comes to the end timing, the driving of the X-ray tube 10 and the C-arm 3 is stopped, and the X-ray tomography is performed based on the data stored in the HDD 63 in step S19. Image reconstruction processing is performed, and output processing for display on the display device 67 (printing out is also acceptable) is performed.

As described above, according to this embodiment,
The C-arm of the angio apparatus has a perfect circular arc shape, and an X-ray tube and a flat panel detector (FDP) are provided at positions facing each other by 180 ° with respect to the center of the C-arm.
Furthermore, by providing the configuration in which the C arm is rotated along the circumference thereof, it becomes possible to function as a simple X-ray CT.

When the C arm is rotated,
X-ray transmission data is sent to FPD1 each time it is rotated by a small angle.
Since it is obtained with 1, it is necessary to shoot at regular intervals. On the other hand, however, the C-arm has a corresponding weight, so that the rotation speed becomes constant even if the rotation is started, or a period for accelerating and decelerating is required to stop the rotation. . Therefore, in reality, the length along the circumference of the extension portion 3b of the C arm 3 shown in FIGS.
It is desirable to set the length longer than the length corresponding to the fan angle θ ′ with respect to the center of the circle.

However, when a rotary encoder that comes into contact with the outer circumference of the C arm 3 is provided and the pulse signal output from this rotary encoder is used as the photographing timing signal of the FPD 11, the timing signal indicates the rotation speed of the C arm 3. However, since the signal depends on the rotation angle, the length of the extension 3b of the C arm 3 along the circumference is
It is also possible to set the fan angle θ ′ with respect to the center of the circle.

<Second Embodiment> In the above embodiment, C
The arm was rotated along its circumference. Therefore, although it is equivalent to the half scan in the normal X-ray CT apparatus, it does not reach the full scan.

Therefore, in the second embodiment, the X-ray CT is used.
An example of realizing a scan equivalent to a gantry in the apparatus will be described.

FIG. 7 is an external view of the angio apparatus according to the second embodiment. The same components as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. Figure 1
Is different from the base support 1 in that the X-ray tube 10 and the FPD 11 are displaced from the end of the C-arm 3 by a distance corresponding to the length of the C-arm holder 4. To rotate 90 degrees, or
The difference from FIG. 1 is about 90 ° on the horizontal plane.

In the second embodiment, in the state where the C-arm holding portion 4 holds the center position of the C-arm 3, the extending direction of the rotating shaft 4b indicated by the arrow B in the figure (the carrying direction of the carrying device 200 = X-ray CT). 8), the rotation axis 4b of the C-arm 4 passes along the line 80 connecting the centers of the X-ray tube 10 and the FPD 11, as shown in FIG. With such a structure, when the C-arm holding part 4 is rotated about its rotation shaft 4b (as shown by the broken lines in FIGS. 7 and 8, the C-arm holding part 4 is placed in the L-shaped support part 2). The motor 2a for rotating in the direction of the arrow B is built in), the X-ray tube 10 and the FPD viewed from the direction of the rotation axis thereof.
The rotation trajectory of 11 is the same as that of FIG.

In the first embodiment, the range of rotation of the C-arm 3 was limited, so only half scanning was possible. However, in the second embodiment, the rotation angle is not limited and the C-arm 3 rotates. It is possible to continue. That is, by adopting the structure of the second embodiment, it becomes possible to perform a full scan and, in some cases, a helical scan, similarly to a normal gantry.

However, according to the configuration of the second embodiment, since the transport direction of the subject is the same as the direction of the rotation axes of the X-ray tube 10 and the FPD 11, the subject can be transported without limitation. No yes FIG. 9 clearly shows this point.

This drawing is a schematic view seen from a direction orthogonal to the carrying direction of the subject. In the figure, the X-ray tube 1
The broken line connecting 0 and the FPD 11 indicates the center position of the scan plane, and the distance L ₀ from this scan plane indicates the scannable range (distance on the Z axis). That is, according to the second embodiment, it is possible to scan within a range of the distance L ₀ from the substantially end (head or foot) of the laid-down subject, and within that range. Thus, it becomes possible to reconstruct an X-ray tomographic image. In other words, depending on the size of the subject, the central portion (abdomen, etc.) must be excluded from the scan target, but this problem can be solved by using it in combination with the first embodiment. .

However, in the case of the second embodiment, as shown in FIG.
As shown in FIG. 8, the center position of the C arm 3 is not used as the rotation axis, but is rotated around the rotation axis 4b at the end of the C arm holding section 4. Therefore, this C-arm holder 4
Is sufficiently long, the C-arm 3 moves away from the rotation axis. Therefore, even if the top plate 201 of the transfer device 200 is continuously conveyed, the tip of the top plate 201 collides with the C-arm. Instead of 3, the C-arm holder 4 is provided.
That is, it becomes L ₁ shown in the figure, and the distance can be gained by the thickness of the C arm 3.

Since the configuration of the operation console in the second embodiment may be the same as that in the first embodiment, the description thereof will be omitted, and in the following, the processing for obtaining the X-ray tomographic image by the above scanning will be described. The procedure will be described with reference to the flowchart of FIG.

First, in step S31, a scan plan is set. According to the second embodiment, the transport device 200
The scanning range can be set to some extent in the transport direction (Z-axis) of the subject by controlling the. That is, many X-ray tomographic images at different Z positions can be obtained. In step S31, such a plan can be set.

When the setting is completed and a scan start instruction is given, the process proceeds to step S32, and the C arm holding unit 4
The C-arm 3 so that the center position of the C-arm 3 is maintained.
Is driven to rotate the motor 4a. Of course, when the C-arm holding unit 4 has already held the central position of the C-arm 3, the process of step S32 is skipped.

In this way, when the preparation for the scan is completed, the driving of the X-ray tube 10 is started and the rotation of the C arm 3 (the driving of the motor 2a in the L-shaped holding portion 2) is started in steps S33 and S34. (The C-arm 3 starts rotating along the arrow B in FIG. 7).

Then, in step S35, the rotational speed of the C-arm 3 (waits until the figure becomes constant.

When the rotation speed of the C arm reaches the desired speed, the process proceeds to step S37, and the angio apparatus 100 is operated.
The transmitted X-ray data from the FPD 11 is received through the interface 65 (temporarily stored in the HDD 63 in order), and the X-ray tomographic image reconstruction processing is performed based on the received X-ray data. Then, in step S38, output processing (printing may be performed) for display on the display device 67 is performed.

Then, steps S37 and S38 are repeated until it is determined in step S39 that the scan for obtaining the planned tomographic image is completed.

When it is determined that the scan according to the scan plan is completed in this way, the process proceeds to step S40, the rotation of the C-arm 3 (drive of the motor 2a) is stopped, and this process is ended.

As a result of the above, according to the second embodiment,
The C-arm is rotatably supported by a support member that supports the central position of the C-arm 3, and the C-arm is rotated about the support position, which cannot be achieved in the first embodiment.
It becomes possible to perform a scan to obtain an X-ray tomographic image by a full scan, and it becomes possible to obtain many X-ray tomographic images in one scan plan.

Further, by adopting the structure of the second embodiment, the operation of the first embodiment can be performed. That is, in the state of FIG. 7, by rotating the L-shaped support portion 2 by 90 ° with respect to the base support base 1, a configuration equivalent to that of FIG. 1 is obtained.

On the other hand, if only the scanning method in the second embodiment is used and the scanning method in the first embodiment is not used together, C in the second embodiment is used.
The arm 3 does not need a mechanism for sliding it with respect to the C-arm holding portion 4. Further, the C-arm holding portion 4 is not necessary, and the C-arm 3 may be directly attached to the rotation shaft of the L-shaped support portion 2 and rotated (in this case, L
The character-shaped support portion 2 will function as a C-arm holding portion). Further, the X-ray tube 10 and the FPD 11 do not need to be horizontally displaced by a distance corresponding to the length of the C-arm holding portion 4 as shown in FIG. 7 (the positional relationship shown in FIG. 1). Further, the X-ray tube 10 and the FPD 11 may have any shape as long as they have an opening for carrying the subject, so that the shape of the arm does not need to be a true arc, and may be a "U" or "U" shape. become.

The first and second embodiments have been described above. Although some conditions for obtaining an X-ray tomographic image are satisfied by the structure of the angio apparatus 100 of the first and second embodiments, the process of reconstructing an X-ray tomographic image and the control of the angio apparatus are It is realized by a computer program operating on the operation console 300. Therefore,
The present invention also includes a computer program in its category.

Further, the computer program is typically
Since a computer-readable storage medium such as a floppy (registered trademark) disk or a CDROM is set in a computer and installed or copied, it is obvious that such a computer-readable storage medium is also included in the scope of the present invention.

As described above, according to the present invention, it is possible to reconstruct an X-ray tomographic image as a simple X-ray CT even though it is an angio apparatus.
