Description

  The present invention rationally acquires necessary imaging data in a CT apparatus when performing computed tomography (Computed Tomography; abbreviated as “CT”) for diagnosing pets (pets) such as dogs and cats. For technology.

  Computed tomography (CT) has been in widespread use (and mass production and cost reduction associated therewith) for the purpose of treating the degree of injury and the cause of illness. In recent years, it has come to be used not only for human screening but also for screening of pets (inspected animals).

In the case of a pet (animal to be inspected), since the words cannot be understood, an instruction “do not move” cannot be made in order to make a captured image clear when performing a CT scan. Therefore, anesthesia must be used to suppress the movement of the pet (animal to be inspected).
However, in medical treatment using anesthesia, in order to put a physical burden on the pet (animal to be inspected), the pet owner often fails to agree to the use of anesthesia and cannot perform a medical examination. When anesthesia is used, care time is required until the anesthesia is awakened. Therefore, there is a problem that the medical examination time becomes long (about one hour from anesthesia preparation to recovery), and the total cost of the medical care increases.

As a technique for suppressing the movement of the subject animal without using anesthesia, there is a technique disclosed in Patent Document 1. In this technique, the front limbs, hind limbs, and head of an animal are each fixed with independent holders. It is disclosed that the movement of the animal to be inspected can be suppressed without using anesthesia if this animal retainer is used.

Japanese Patent No. 6181251

In the “animal holding device” according to Patent Document 1, the following points are problems.
First, since the abdomen of the animal to be examined is not restrained, there is a possibility that the captured image near the built-in will be blurred.

  Second, although the limb of the subject animal is restrained at a position suitable for imaging, it does not appear to be a calm position for the subject animal. For this reason, the subject animal often squeals and barks and loses calmness before photographing. As a result, it is often the case that a good shot image cannot be taken or it takes time to settle down.

  Thirdly, since the limbs of the animal to be inspected are restrained by the limb body holders, adjustment work is required depending on the thickness of each limb in the animal to be inspected, so that preparation takes time. For this reason, the time during which the test animal is stressed becomes longer until the test is completed. Test animals that feel stress will squeak and bark, lose their calmness, and cannot take good images.

The problem to be solved by the first invention is to provide a technique capable of providing a calm state as soon as possible without using anesthesia for an inspected animal and performing CT imaging that facilitates obtaining good image data.

  The inventor of the present application has empirically grasped the following. That is, an animal to be inspected that has been kept as a pet is more likely to be calm and gentle when in contact than to be restrained by separating the left and right limbs. Utilizing such characteristics, the present invention has been achieved.

(First invention)
The first invention relates to an apparatus (CT examination container) for restricting the movement of an animal to be examined (C or D) in order to improve the reliability of CT imaging.
That is, the container main body (10) capable of accommodating the subject animal by allowing one surface to be opened, and the container lid (11) capable of opening and closing the openable surface of the container main body (10) And comprising.
A cross-sectional shape perpendicular to the longitudinal direction of the housing main body (10) is an abdominal support portion (abdominal support plate 15) narrowed toward the bottom side.

(Glossary)
“CT imaging” is imaging for obtaining an image from X-ray data transmitted through an affected area. In general, analog X-ray data is processed into digital data.

  The “accommodating portion lid (11)” may be configured to open and close the upper surface of the accommodating portion main body (10) (see FIG. 1 and the like), or may open and close the side surface of the accommodating portion main body (10) ( (See FIG. 7). In addition to the case where the housing lid (11) is plate-shaped (see FIG. 1 and the like), the housing lid (11) is bent to widen the internal space of the housing main body (10) (FIG. 6B). (See) or curved (not shown).

  “A cross-sectional shape perpendicular to the longitudinal direction of the housing main body (10)” that “narrows toward the bottom side” of the “abdomen support portion” is a shape that narrows linearly (see FIG. 1 and the like). Alternatively, it may be curved and narrowed (see FIG. 6B).

(Function)
The accommodation section lid (11) of the CT examination accommodation apparatus (10) is opened, and the subject animal (C or D) is accommodated in the internal space. When the container is stored, the container cover (11) is closed.
Since the cross-sectional shape perpendicular to the longitudinal direction in the CT examination storage device (10) is narrowed toward the bottom, the left and right sides of the limb of the subject animal (C or D) approach. In many cases, since they are in contact with each other, they are often more settled than when the left and right limbs are separated. The abdomen rests on the limbs that are in contact with the left and right, and movement of all limbs and abdomen is restricted.

As described above, CT imaging can be performed in a state in which the movement of the subject animal (C or D) is extremely limited, so that the captured image is less likely to be blurred and high-quality image data can be easily obtained.
In other words, it is easy to obtain high-quality image data, so that there is an increased possibility that data used for medical care can be obtained even if the performance of the CT apparatus (acquisable image density = number of tomographic images) is not high. Therefore, even a relatively low cost CT apparatus can be used for medical treatment.

(Variation 1 of the first invention)
The CT examination container according to the first invention is more preferably formed as follows.
That is, the CT inspection container (the container main body 10) is formed so that the width of the inner space is smaller than the body width when the animal to be inspected sits (see FIG. 2C). It is.

(Glossary)
The “body width dimension when the subject animal sits” is a dimension measured when the subject animal bends its limbs and puts its abdomen on the ground (when sitting). D) becomes larger than the body width dimension (see FIG. 8 (a)) in the state in which it stands up. The “dimension smaller than the body width when the animal to be inspected sits” is approximately 90 to 70%. As a result, the lateral width dimension of the internal space of the accommodating portion main body (10) is about 0.7 W to 1.2 W on the basis of the body width (W).

(Function)
Since the lateral width dimension of the internal space of the CT examination container (the container body 10) is smaller than the body width dimension when the animal to be examined is sitting, the movement of the whole body is large for the animal to be examined (C or D). Limited. Since CT imaging can be performed in a state in which the movement of the subject animal (C or D) is extremely limited, the captured image is less likely to be blurred, and high-quality image data can be easily obtained.

(Variation 2 of the first invention)
It is more preferable that the CT inspection container according to the first invention is made of a colorless and transparent material.
The colorless and transparent material is mainly a thermoplastic resin. More specifically, acrylic resin, polyurethane terephthalate (PET), and the like.

(Function)
For the test animal (C or D), the field of view is not greatly deprived, so the stress is small.
For veterinarians, laboratory technicians, owners of animals to be examined (C or D), etc., the state of the animals to be examined (C or D) can be observed during or before CT photography.

(Variation 3 of the first invention)
The CT examination container according to the first invention is more preferably formed as follows.
That is, the side surface (for example, the long side plate 12 and the short side plate 14) and the upper surface (for example, the storage unit lid body 11) of the CT examination storage device (the storage unit body 10) have ventilation openings for ensuring the ventilation of the internal space. A hole (10A) is provided.

(Function)
The ventilation hole (10A) reduces the restriction on breathing of the animal under test (C or D). Moreover, the temperature rise of the internal space of the accommodating part main body (10) is suppressed.

(Variation 4 of the first invention)
The CT examination container according to the first invention is more preferably formed as follows.
In other words, a fan-shaped main body (21) composed of a fan-shaped plate and a head restraint (20) including a fixed body (23, 24) for holding the fan-shaped main body (21) in a curved state. (See FIG. 4).
Then, the head restraint tool (20) is elastically deformed in a state of being wound around the neck of the animal to be inspected (C or D) using the fixed body (23, 24). It can be inserted into the internal space of (10) (see FIG. 5).

(Glossary)
If the head restraint (20) is diverted to a so-called “color” (selecting an appropriate size and cutting it if necessary to change it to the appropriate size) Is reasonable. Here, the “color” is a treatment instrument used to prevent the treatment site (C or D) from touching the treatment site with the foot after treating the head such as eyes, ears, and mouth.

(Function)
The head restraint tool (20) is attached to the neck of the subject animal (C or D). In other words, the fixed body (23, 24) is used to wrap around the neck of the head restraint tool (20) and fix it. In this state, it is elastically deformed and inserted into the internal space of the housing main body (10).
Since the head restraint tool (20) and the inner wall forming the internal space of the housing main body (10) are in contact with each other, the head restraint tool (20) It is necessary to apply a force that resists further elastic deformation. Therefore, the subject animal (C or D) is difficult to move the head. However, although the subject animal (C or D) does not move its head, it is not in a restrained state in which it cannot be moved at all, so the stress is smaller than in a completely restrained state. As a result, the captured image is less likely to be blurred, and it is easier to obtain high-quality image data, particularly for the head.

(Second invention)
The second invention relates to a CT apparatus (30) using the CT examination container (10) according to the first invention.
That is, an X-ray irradiation apparatus (31) and an object to be inspected that is irradiated with X-rays from the X-ray irradiation apparatus (31) is an X-ray irradiation space of the X-ray irradiation apparatus (31) (the cylinder in FIGS. 3 and 10). Fixed to the moving table (32), the moving table (32) for moving the moving table (32) to the X-ray irradiation space, and the moving table (32). And a CT examination container (10) that is irradiated with X-rays in the X-ray irradiation space.
The CT examination storage device (10) includes a storage unit main body (10) capable of storing the animal to be inspected by making one surface openable, and an openable surface of the storage unit main body (10). A container lid (11) that can be opened and closed, and a cross-sectional shape perpendicular to the longitudinal direction of the container body (10) is an abdomen support part (abdomen support plate 15) narrowed toward the bottom side; To do.

(Function)
The accommodation section lid (11) of the CT examination accommodation apparatus (10) is opened, and the subject animal (C or D) is accommodated in the internal space. When the container is stored, the container cover (11) is closed.
Since the cross-sectional shape perpendicular to the longitudinal direction in the CT examination storage device (10) is narrowed toward the bottom, the left and right sides of the limb of the subject animal (C or D) approach. In many cases, since they are in contact with each other, they are often more settled than when the left and right limbs are separated. The abdomen rests on the limbs that are in contact with the left and right, and movement of all limbs and abdomen is restricted.

The CT examination container (10) containing the animal to be examined (C or D) is fixed to the movable table (32). Then, the table moving device (33) is operated to move the CT examination storage device (10) to the X-ray irradiation space of the X-ray irradiation device (31), and X-rays are applied to the inspected animal (C or D). And tomography is performed.
Since the lateral width dimension of the internal space of the CT examination container (the container body 10) is smaller than the body width dimension when the animal to be examined is sitting, the movement of the whole body is large for the animal to be examined (C or D). Limited. Since CT imaging can be performed in a state in which the movement of the subject animal (C or D) is extremely limited, the captured image is less likely to be blurred, and high-quality image data can be easily obtained.

(Variation 1 of the second invention)
The CT inspection container in the second invention is more preferably formed as follows.
That is, the container body (10) is formed such that the width of the internal space is smaller than the body width when the animal to be inspected sits (see FIG. 2 (c)).

(Variation 2 of the second invention)
It is more preferable that the CT inspection storage device (storage body 10) in the second invention is made of a colorless and transparent material.
Further, the side surface (for example, the long side plate 12 and the short side plate 14) and the upper surface (for example, the storage portion lid body 11) of the CT examination storage device are provided with ventilation through holes (10A) for ensuring ventilation of the internal space. This is more preferable.

(Variation 3 of the second invention)
The CT inspection container in the second invention is more preferably formed as follows.
That is, a head-shaped restraining device (20) including a fan-shaped main body (21) made of a fan-shaped plate and a fixed body (23, 24) for holding the fan-shaped main body (21) in a curved state is provided. (See FIG. 4).
Then, the head restraint tool (20) is elastically deformed in a state of being wound around the neck of the animal to be inspected (C or D) using the fixed body (23, 24). It can be inserted into the internal space of (10).

(Variation 4 of the second invention)
The CT inspection container in the second invention is more preferably formed as follows.
In other words, the fixing means of the movable table (32) and the CT inspection container (10) are surface fasteners (17, 34) fixed in advance to the surfaces in contact with each other (see FIG. 9).

By adopting a surface fastener as the fixing means for the movable table (32) and the CT examination container (10), the operation of changing the imaging direction can be performed very easily. Fixing means will not interfere with shooting.

According to the first aspect of the present invention, it is possible to provide a CT examination container for providing a calm state as soon as possible without using anesthesia for an animal to be examined, and for performing CT imaging that facilitates obtaining good image data. did it.
According to the second aspect of the present invention, it is possible to provide a CT apparatus for providing a calm state as soon as possible without using anesthesia for an inspected animal and performing CT imaging that facilitates obtaining good image data.

It is a figure which shows the variation of the accommodating part cover body in the accommodating apparatus for CT inspection which concerns on embodiment of this invention. It is a figure for defining the dimension of each part of the body of a to-be-inspected animal. It is a perspective view which shows the fixing means of the accommodation apparatus for CT inspection, and the moving stand of CT apparatus. It is a perspective view which shows the case where CT imaging by CT apparatus is performed when the technique shown by the prior patent document 1 is used.

  Embodiments of the present invention will be described with reference to the drawings. The drawings used here are FIGS. 1 to 9. FIG. 10 shows the technique disclosed in the prior art document 1, which is used for comparative reference.

  FIG. 1 and FIG. 2 show a CT examination container for restricting the movement of an animal to be examined (a cat in FIGS. 1 and 2) in order to improve the reliability of CT imaging.

  The housing part main body 10 which can accommodate the cat which is a test object by making the upper surface openable, and the housing part lid body 11 which can open and close the openable surface of the housing part main body 10 are provided. The accommodating part lid 11 can be opened and closed by a hinge 13 (see FIG. 2) fixed to the upper part of one side (the rear side in FIG. 1) of the long side plate 12 in the accommodating part main body 10. Moreover, the long side plate 12 on the opposite side to which the hinge 13 is fixed is provided with a lid fixing tool 16 for maintaining the housing lid 11 in a tightened state (see FIG. 2).

  The hinge 13 was made of acrylic, including screws, so as not to interfere with X-fountain photography.

  The cross-sectional shape perpendicular to the longitudinal direction in the housing main body 10 is the abdomen support plate 15 that is linearly narrowed toward the bottom side. The lower surface of the abdomen support plate 15 is formed so as to be grounded together with the grounding portion 12A which is the lower end of the long side plate 12 (actually, a fixing fastener is interposed, which will be described later). .

The CT inspection container 10 is formed of a thermoplastic resin plate that is a colorless and transparent material. More specifically, an acrylic resin was employed.
The accommodating portion lid 11, the long side plate 12, and the short side plate 14 of the accommodating portion main body 10 are provided with a large number of ventilation through holes 10A. The ventilation through hole 10A reduces the restriction on the breathing of the animal to be inspected, and suppresses the temperature rise in the internal space of the housing main body 10.

The CT inspection container 10 is formed such that the width of the inner space is smaller than the body width when the animal under test sits (see FIG. 2C).
The “body width dimension when the subject animal sits” is a dimension measured when the subject animal bends its limbs and puts its abdomen on the ground (when sitting). It becomes larger than the body width dimension (see FIG. 8A) in a state where the test animal (C or D) stands up. The “dimension smaller than the body width when the animal to be inspected sits” is approximately 90 to 70%. As a result, the lateral width dimension of the internal space of the accommodating portion main body 10 is about 0.7 W to 1.2 W on the basis of the body width (W).

  Since the lateral width dimension of the internal space of the CT examination container 10 is smaller than the body width dimension when the subject animal sits, the movement of the entire body is greatly restricted for cats and dogs that are subject subjects. However, it is often settled down to protect the abdomen (see FIG. 2D). For this reason, CT imaging can be performed in a state where movement of the subject animal is extremely restricted, so that the captured image is less likely to be blurred, and high-quality image data can be easily obtained. In other words, even an inexpensive CT apparatus can withstand practical use.

The actual dimensions (outer dimensions) of the CT examination container 10 described above are as follows when the animal under examination is assumed to be a miniature dachshund or a normal cat.
The long side plate 12 has a longitudinal size (vertical width dimension) of 500 mm, the short side plate 14 has a width direction size (horizontal width dimension) of 160 mm, and the short side plate 14 has a longitudinal direction size (height dimension) of 250 mm. .
Since the 5 mm thick acrylic resin plate is used, the size of the internal space is
490 x 150 x 240 millimeters.

The dimensions of the cat (C) that was actually examined are as follows (see FIG. 8).
The body length (L) was 42 centimeters, the body height (H) was 30 centimeters, and the body width (W) was 20 centimeters.
It should be noted that the degree of calmness seems to increase when a towel or the like used by the animal to be inspected is put in the gap in the internal space of the CT inspection apparatus 10 in the state where the animal to be inspected has entered.

(Figure 3)
FIG. 3 is a perspective view showing the CT apparatus 30 according to the embodiment of the present invention and the CT examination storage apparatus 10 according to the actual C embodiment of the present invention.
The CT apparatus 30 includes an X-ray irradiation apparatus 31 that irradiates a cylindrical internal space (X-ray irradiation space) with X-rays, and a CT examination storage apparatus 10 that accommodates an animal to be examined in the X-ray irradiation space. And a platform moving device 33 that functions as a driving device for moving the platform 32 in and out of the X-ray irradiation space.

  In FIG. 3, the direction of the body of the subject animal is illustrated so as to be perpendicular to the longitudinal direction of the moving table 32. The direction of the body of the animal under test differs depending on the orientation in which the CT examination container 10 is fixed with respect to the moving table 32. For example, in FIG. 5, the CT examination storage apparatus 10 is fixed to the moving table 32 so that the direction of the body of the subject animal is parallel to the longitudinal direction of the moving table 32.

(Fig. 4)
FIG. 4 shows a head restraint 20 that restrains the movement of the head of the subject animal.
The head restraining tool 20 includes a fan-shaped main body 21 made of a fan-shaped plate, a fixing band 23 for holding the fan-shaped main body 21 in a curved state, and a surface fastener fixed to the fixing band 23. The belt-side fastener 24 and the belt-side fastener 24 that can be fixed and fixed to the fan-shaped main body 21 are provided.

  The fan-shaped main body 21 is formed of a thermoplastic resin that is easily elastically deformed, and includes a large number of through-holes so as not to hinder the breathing of the animal under test. We use pet goods called “color”.

  As shown in FIGS. 4B and 4C, the head restraining tool 20 is fixed to the neck of the subject animal (C or D) by the fixing band 23, the band-side fastener 24, and the body-side fastener. Wrapping using 25. And the to-be-inspected animal (C or D) of the state which wound the head restraint tool 20 around the neck is accommodated in the internal space of the said accommodating part main body 10. FIG. At that time, the head restraint tool 20 is further elastically deformed. (See FIG. 5).

(Fig. 5)
As shown in FIG. 5, the head restraint tool 20 and the inner wall forming the internal space of the container body 10 are in contact with each other, so that the animal under test (C or D) moves the head, the head restraint tool. A force against 20 further elastic deformations must be applied. Therefore, the subject animal (C or D) is difficult to move the head.
However, although the subject animal (C or D) does not move its head, it is not in a restrained state in which it cannot be moved at all, so the stress is smaller than in a completely restrained state. As a result, the captured image is less likely to be blurred, and it is easier to obtain high-quality image data, particularly for the head.

(Fig. 6)
Fig.6 (a) is a side view which shows the variation of an abdominal part support plate. In the embodiment shown in FIG. 1 and the like, the abdominal abdomen support plate 15 is square for reasons of ease of manufacture, but in this embodiment, a curved plate-like abdomen support plate 15A is employed. It is expected that the curved abdominal support plate 15A can reduce the stress on the subject animal (C or D).

FIG.6 (b) is a side view which shows the variation of a accommodating part cover body. In the embodiment shown in FIG. 1 and the like, the plate-shaped accommodation unit lid 11 is used. However, in this embodiment, a bent type accommodation unit lid 11A that swells upward is employed.
Since a large internal space of the container main body 10 can be secured, it is expected that the stress can be reduced in the case of an inspected animal with a large body height (see FIG. 8B).

(Fig. 7)
In FIG. 7, the variation of the accommodating part cover body in the accommodation apparatus for CT inspection is shown. In the embodiment shown in FIG. 1 and the like, the case where the upper surface of the accommodating portion main body 10 is opened and the accommodating portion lid 11 is provided on the upper surface has been shown.
In this embodiment, one side of the short side surface is opened in the storage unit main body 10, and the storage unit lid 11B is provided on the surface. Depending on the type of animal being examined, this may be easier to accommodate.

(Fig. 9)
In FIG. 9, it shows about the fixing means of the accommodating part main body 10 and the movable stand 32, and the fixing direction. As for the movement No. 32, the actual dimension is longer in the longitudinal direction.
A hook-and-loop fastener 34 is fixed to the upper surface of a predetermined portion of the movable table 32, and the hook-and-loop fastener 17 is also fixed to the bottom surface of the housing main body 10. With these hook and loop fasteners 17 and 34, the container main body 10 that contains the animal to be inspected (C or D) is fixed to the movable table 32.

Since the surface fastener is adopted as the fixing means, the operation of changing the direction in which the CT scan is performed becomes easy.
FIG. 9A shows fixation in a state where the moving direction of the moving table 32 is made to coincide with the body length direction of the subject animal. This direction is the same as in FIG.
FIG. 9B shows fixation in a state where the moving direction of the moving table 32 is perpendicular to the body length direction of the subject animal. This direction is the same as in FIG.

(Fig. 10)
FIG. 10 is a diagram illustrating a case where an inspection by a CT apparatus is executed by the technique disclosed in Patent Document 1.
Compared with the embodiment described above, the movement of the test subject cannot be suppressed. Therefore, the possibility of obtaining high quality image data is reduced.
Further, it is imagined that it is not easy to change the CT scanning direction.

As described above, according to the present embodiment, it is possible to provide a calm state as soon as possible without using anesthesia for an animal to be inspected, and to perform CT imaging that facilitates obtaining good image data.
Further, since it is easy to obtain high-quality image data even with a relatively inexpensive CT apparatus, it can be expected that the CT apparatus will be widely used in animal hospitals.

The size of the container main body 10 shown in FIG. 2 is suitable for small adult dogs and cats, but the size of the container main body 10 is changed according to the size of the animal to be examined. Of course.
In addition, since the exact | strict dimension is not requested | required with respect to the magnitude | size of a to-be-inspected animal, if it prepares in multiple types of size beforehand, it will be considered that it can respond to most tests.

It has applicability in the veterinary industry, medical equipment manufacturing industry, medical equipment maintenance industry, medical equipment rental industry, etc.
