The present invention relates to an open-and-closed tomography apparatus.

A tomography device is a device used to obtain a cross-sectional image or information corresponding thereto by transmitting radiation through an object to be measured and analyzing the degree of attenuated signals thereof. Therefore, a tomography apparatus requires a radiation module for generating radiation and irradiating it to an object to be inspected, and a measurement module for generating an electrical signal by acquiring a radiation signal re-emitted from the object to be inspected.

In the case of existing industrial tomography devices, the size of the radiation module and measurement module described above is very large, and the space required for measurement reaches 2.5 to 3 times the diameter of the measurement object. Therefore, when the object to be inspected is restricted by the surrounding structure, it is not easy to approach the industrial tomography device to the object to be inspected, so there is a problem that measurement using the tomography device cannot be performed.

In addition, even in a situation where measurement can be performed using a tomography device, the time required to install the tomography device for proper measurement according to locational constraints takes about several hours at most, and the time required for measurement also reaches about 10 hours. had a downside.

The present invention has been made to solve these problems, and to provide a tomography apparatus that reduces the size of the required space and is easy to install around an object to be inspected.

The measuring unit 10 includes a radiation unit 102 and a detecting unit 101 . The measuring unit 10 may irradiate the radiation R to the object OB and detect the radiation R obtained from the object OB as a result. Each of these roles may be performed by the radiating unit 102 and the detecting unit 101 respectively. The radiation unit 102 may include a radiation source 17 provided to emit radiation R, and the detector 101 may include a detector 16 provided to detect the radiation R.

The measurement unit 10 may include a measurement ring 11 . The measurement ring 11 may include a radiation ring 112 included in the radiation unit 102 and a detecting ring 111 included in the detecting unit 101 . The radiation ring 112 and the detecting ring 111 may be formed in a half-ring shape by cutting a ring in half. Since the radiation ring 112 and the detecting ring 111 are rotatably coupled to each other, an annular measurement ring 11 may be formed. The radiation ring 112 and the detecting ring 111 may be coupled to each other to allow relative rotation in the reference direction D in the axial direction. The radiation ring 112 and the detecting ring 111 may be rotatably coupled to each other at a measurement hinge 12 disposed on one side of each end to form an annular measurement ring 11 . As it rotates, the other ends of the radiation ring 112 and the detecting ring 111 may be in contact with each other or spaced apart from each other.

Radiation source 17 may be coupled to the center of radiation ring 112 . Here, the center of the radiation ring 112 means a position on the radiation ring 112 located at the same distance from both ends of the radiation ring 112 . The radiation source 17 is a component that emits radiation R. Accordingly, the radiation source 17 may have a sealed radioisotope therein to emit radiation R. In order to emit only the radiation (R) emitted in a desired direction among the radiation (R) in a random direction emitted by the radioactive isotope to the outside of the radiation source 17, the radiation source 17 includes a radiation collimator surrounding the sealed radioactive isotope. can include The radiation collimator may be configured to have a plurality of fine holes or slits, so that radiation emitted in an unwanted direction is blocked and only radiation emitted in a direction parallel to the holes or slits may be emitted. In one embodiment of the present invention, a radiation collimator may be formed such that radiation R is emitted in a fan beam form, as shown by hatched areas in FIG. 4 . Radiation R emitted by the radiation source 17 may spread out at right angles.

The detector 16 is coupled to the detecting ring 111 and is provided to detect radiation R emitted from the object OB. The detector 101 may include a detector 16 collimator having a radiation detection window through which radiation R may be guided to the detector 16 .

The detector 16 may be an array of detectors 16 formed along the profile of the detecting ring 111 . Therefore, the detector 16 may be formed in an arc shape along the profile of the detecting ring 111, such as the circumference of a semicircle, to surround a portion of the object OB.

The radiation unit 102 and the detecting unit 101 are rotated relative to each other, so that the detection state forming the measuring unit 10 surrounding the inspection object OB or the inspection object OB is the radiation unit 102 and It can selectively have a non-sensing state that can be separated from the detecting unit 101 . In the detection state, both ends of the radiation unit 102 and the detection unit 101 meet each other, and the measurement unit 10 forms a ring and is placed in the state of FIG. 4 surrounding the object OB, and rotates in the non-sensing state. As a result, one end of the radiation unit 102 and the detection unit 101 may be separated from each other, and the object OB may escape from the inside of the measurement unit 10 as shown in FIG. 5 . Since the tomography apparatus 1 according to an embodiment of the present invention can be selectively placed in each state, it is possible to easily install the tomography apparatus 1 around the object OB in a state in which imaging is possible. .

The measurement unit 10 may be disposed inside the frame unit 20 to enable relative rotation in the axial direction in the reference direction D with respect to the frame unit 20 in the sensing state. However, unlike the detecting unit 101 and the radiating unit 102 that are rotatably coupled to each other on one side, the measurement unit 10 is a virtual plane passing through the center point in the reference direction D when viewed along the reference direction D. It can rotate around an axis. That is, the measurement unit 10 can rotate around the object OB that can be located inside the measurement ring 11 . As the measurement unit 10 is rotated, the radiation source 17 and the detector 16 can also rotate, the radiation R is evenly radiated throughout the object OB, and the detector 16 has no dead angle. Accurate information can be obtained.

Gear teeth may be formed on the outer surface of the measurement ring 11 along the circumferential direction. A driving unit to be described later is gear-coupled to these gear teeth and transmits a driving force to cause the measurement ring 11 to rotate in the reference direction D as an axial direction.

Frame part (20)

The frame unit 20 includes a radiation frame 202 into which the radiation unit 102 can be embedded and a detecting frame 201 rotatably coupled to the radiation frame 202 and into which the detection unit 101 can be embedded. do. The radiation unit 102 may be rotatably coupled to the inner surface of the shell 21 of the radiation frame 202, and the detecting unit 101 rotates to the inner surface of the shell 21 of the detecting frame 201. can possibly be combined. The frame unit 20 surrounds and protects the measurement unit 10, and may be a skeleton fixed so that the measurement unit 10 rotates. Like the radiation part 102, the radiation frame 202 may be rotatably coupled to the detecting frame 201 through a frame hinge 22. Therefore, the detecting frame 201 and the radiation frame 202, similar to the detecting part 101 and the radiating part 102, respectively, when viewed along the reference direction D, are formed in a semi-ring shape by cutting each ring in half. can

The detecting frame 201 and the radiation frame 202 form a single ring by rotation of one side in a state where the detecting unit 101 and the radiating unit 102 are built-in, respectively, or their ends are spaced apart from each other. The detection unit 101 and the radiation unit 102 may also be rotated together by the rotation of the detecting frame 201 and the radiation frame 202 to change the state.

The detecting frame 201 and the radiation frame 202 include two plates spaced apart from each other along the reference direction D, and spaced apart plates extending along the reference direction D to connect these two plates to each other. A detecting shell 211 and a radiation shell 212 surrounding the detecting unit 101 and the radiating unit 102 may be provided, including a plurality of pillars, respectively. Accordingly, the measuring unit 10 may be exposed to the outside along a direction orthogonal to the reference direction D. However, the frame unit 20 may have a torus-shaped shell 21 in which the measurement unit 10 is not exposed to the outside.

The frame unit 20 may include a driving unit provided to rotate the measuring unit 10 within the shell 21 in the reference direction D as an axial direction in the sensing state. The driving unit includes a driving member that generates driving force by receiving electric power, and a driving gear 23 that is connected to the driving member and serves as a medium for transmitting the driving force but is gear-coupled to gear teeth formed on the outer surface of the instrument ring 11. can do.

A plurality of frame rollers 24 may be arranged at predetermined intervals along the circumferential direction of the outer shell 21 .

The measurement ring 11 is sandwiched between the frame roller 24 and the drive gear 23 so that the measurement ring 11 does not depart from the frame portion 20 and moves in the reference direction D within the frame portion 20. Rotation in the axial direction may be possible. This is because the frame roller 24 may be disposed inside the measurement ring 11 and the drive gear 23 may be disposed outside the measurement ring 11 . Accordingly, the frame roller 24 may be used to guide the rotation of the metering ring 11 .

support holder (40)

The support holder 40 is a component for supporting the frame part 20 and is disposed on one side of the frame part 20 with respect to the reference direction D. The support holder 40 is coupled to the frame unit 20 and is provided to surround the inspection object OB.

The support body 41 may include a first support body 411 and a second support body 412 . The support body 41, like the frame portion 20, the first support body 411 and the second support body 412 may be rotatably coupled to each other through the support hinge 42. Therefore, when viewed along the reference direction (D), the first support body 411 and the second support body 412 may be formed in a semi-ring shape by cutting the ring in half.

The first support body 411 and the second support body 412 can be selectively placed in a sensing state forming a single ring by rotation of one side or a non-sensing state in which one end is spaced apart from each other, and the detecting frame 201 ) and the rotation of the radiation frame 202 may be placed in a sensing state or a non-sensing state.

The support member 43 extends along the reference direction D, and both ends are coupled to the support body 41 and the frame unit 20, respectively. The support member 43 is composed of two pieces, one of which is the first support member 431 to the first support body 411 and the detecting frame 201, and the other is the second support member 432 to the first support body 411 and the detecting frame 201 2 may be coupled to the support body 412 and the radiation frame 202.

An end of the support member 43 may be coupled to the frame unit 20 so as to be slidable and rotatable along the frame unit 20 . To enable this movement, the end of the support member 43 may have a ball joint structure. The support connection portion 25, which is a portion on the frame portion 20 to which the end of the support member 43 is coupled, is a frame portion so that the end of the support member 43 can slide along the radial direction of the frame portion 20 ( 20) may have the form of a slot extending along the radial direction. Since the support member 43 and the frame part 20 have a coupling structure of this type, even if the frame part 20 is tilted by the tilting holder 30 to be described later, the support holder 40 stably supports the frame part (20) can be supported.

The support holder 40 may include a support roller 44 rotatably disposed inside the support body 41 . Support roller 44 may be composed of a plurality. A plurality of support rollers 44 may be rotatably coupled to a surface of the support body 41 facing the object OB. Accordingly, the support roller 44 may be used to support the object OB.

FIG. 7 is a view showing a shape in which the tilting holder 30 of the tomography apparatus 1 according to an embodiment of the present invention is placed in a non-sensing state. 8 is a side view illustrating a state in which the frame unit 20 is tilted by operating the tilting holder 30 of the tomography apparatus 1 according to an embodiment of the present invention.

The tilting holder 30 is a component for imparting an inclination to the frame portion 20, and includes a tilting body 31 and an inclination adjusting member 33. The tilting body 31 is disposed on the other side of the frame unit 20 with respect to the reference direction D and is provided to surround the object OB.

The tilting body 31 may include a first tilting body 311 and a second tilting body 312 . In the tilting body 31 , like the frame unit 20 , the first tilting body 311 and the second tilting body 312 may be rotatably coupled to each other through the tilting hinge 32 . Accordingly, the first tilting body 311 and the second tilting body 312 may each be formed in a semi-ring shape obtained by cutting a ring in half when viewed along the reference direction D.

The first tilting body 311 and the second tilting body 312 can be selectively placed in a sensing state forming a single ring by rotation of one side or a non-sensing state in which one end is spaced apart from each other, and the detecting frame 201 ) and the rotation of the radiation frame 202 may be placed in a sensing state or a non-sensing state.

The ends at which the first tilting body 311 and the second tilting body 312 are coupled to each other are referred to as coupling ends 3111 and 3121, respectively, and the ends located on the opposite side of the coupling ends 3111 and 3121 are Let them be free ends 3112 and 3122, respectively. When viewed along the reference direction D, a straight line connecting the tilting hinge 32 and the free end 3112 of the first tilting body 311 in the non-sensing state of FIG. 7 and the tilting hinge 32 and the second 2 The coupling end 3111 of the first tilting body 311 and the coupling end of the second tilting body 312 ( 3121) can be formed. That is, when the aforementioned two straight lines form a right angle, one surfaces of the coupling ends 3111 and 3121 may come into contact with each other so that the first tilting body 311 and the second tilting body 312 may no longer rotate in the direction in which they are widened. To enable such contact, one surfaces of coupling ends 3111 and 3121 of the first tilting body 311 and the second tilting body 312 may be formed by being obliquely cut.

The structure of the coupling ends 3111 and 3121 is not limited to the tilting holder 30, and may be equally applied to the support holder 40, the frame unit 20, and the measurement unit 10.

The tilt adjusting member 33 extends along the reference direction D and both ends are coupled to the tilting body 31 and the frame part 20, respectively, and the frame part 20 is on a plane orthogonal to the reference direction D It is provided to adjust the inclination it has to the The tilt adjusting member 33 may be composed of two pieces.

The first tilt adjusting member 331 may be disposed closer to the tilting hinge 32 than the second tilt adjusting member 332, but the positional relationship is not limited thereto.

An end of the tilt adjusting member 33 may be coupled to the frame unit 20 so as to be slidable and rotatable along the frame unit 20 . To enable this movement, the end of the tilt adjusting member 33 may have a ball joint structure. The tilting connection part 26, which is a part on the frame part 20 to which the end of the tilt adjusting member 33 is coupled, is a frame so that the end of the tilt adjusting member 33 can slide along the radial direction of the frame part 20. It may have the form of a slot extending along the radial direction of the portion 20 . Since the tilt adjusting member 33 and the frame unit 20 have such a coupling structure, even when the frame unit 20 is tilted, the tilt adjusting member 33 remains extended along the reference direction D. can keep

The plurality of tilt adjusting members 33 may adjust the inclination of the frame unit 20 in such a way that the lengths protruding from the tilting body 31 toward the frame unit 20 are differently adjusted. Therefore, the tilt adjusting member 33 may include a lead screw whose length protrudes from the tilting body 31 can be adjusted, and may include a screw advancing member for rotating the lead screw. The screw advancing member may be a motor or an actuator that receives electric power and generates a driving force, but the type is not limited thereto.

For example, in the state of FIG. 2, the protruding length of the first tilt adjusting member 331 toward the frame portion 20 is reduced, so that the upper end of the frame portion 20 tilts the body 31 as shown in FIG. 8. can be inclined towards The operation of the same frame unit 20 can be achieved by increasing the protruding length of the second tilt adjusting member 332 toward the frame unit 20 . Conversely, when each tilt adjusting member 33 operates, the frame unit 20 may be tilted in the opposite direction.

On a plane orthogonal to the reference direction (D), a straight line connecting the positions where the two support members 43 are coupled to the frame portion 20, respectively, is a straight line connecting the two tilt adjusting members 33 to the frame portion 20. It may be orthogonal to the straight line connecting the positions to be coupled to each other. Therefore, even when the frame part 20 is tilted due to the length difference of the inclination adjusting member 33, the support member 43 can stably support the frame part 20 without being deformed or receiving an excessive load. However, the positional relationship between the support member 43 and the tilt adjusting member 33 is not limited thereto.
