Description

X-ray imaging device

[0001] This invention relates to an X-ray imaging device.

[0002] X-ray imaging is a radiographic method that utilizes the penetrative and rectilinear properties of X-rays. Based on the X-ray attenuation accumulated during the process of penetrating the target, it displays the difference in X-ray transmittance according to the internal structure of the target as a gray-level X-ray image.

[0003] X-ray images can be classified in various ways. For example, in the field of dentistry, where the region of interest is the teeth and surrounding tissues, X-ray panoramic images, CT images (Computed Tomography images), and X-ray cephalometric images (hereinafter referred to as X-ray cephalometric images) are primarily used.

[0004] With the diversification of X-ray imaging types, so-called multimodality X-ray imaging devices capable of capturing different types of images with a single unit have been introduced and are widely used. For example, in dentistry, X-ray imaging devices capable of capturing panoramic, CT, and cephalometric X-ray images are used.

[0005] In such an X-ray imaging device, the head of the subject is supported by a part of a handle frame connected to a column and aligned to the imaging position, and a gantry equipped with a generator and a first detector facing each other with the subject in between rotates and moves around an axis between the generator and the first detector to capture an X-ray panoramic or CT image. In addition, for X-ray cephalometric imaging, a separate arm is connected to the column, and a sensor end including a separate second detector is provided at the end of the arm, and when the subject moves to the end of the arm and is aligned to a position close to the sensor end, an X-ray cephalometric image is captured using the generator of the gantry and the second detector of the sensor end.

[0006] At this time, the arm supporting the sensor unit for X-ray cephalometric imaging is a left-handed or right-handed type that extends to the left or right of the column, and the direction of extension has been fixed, but shielding rooms in hospitals vary in size and shape and are mostly narrow, so installation constraints arose depending on the direction of extension of the arm.

[0007] The technology forming the background of this invention is disclosed in Korean Registered Patent Publication No. 10-2193930.

[0008] The present invention aims to solve the problems of the aforementioned conventional technology by providing an X-ray imaging device capable of changing the arm to a left-hand type or a right-hand type with respect to the column.

[0014] Additionally, the arm may face a first direction, the first connecting part and the second connecting part may be joined in the first direction or a second direction different from the first direction, and the column may face a third direction.

[0015] In addition, the first connecting part and the second connecting part may be detachably coupled or rotated so that the arm is rotated 180 degrees around the second direction or the third direction as an axis, depending on the first connecting state and the second connecting state.

[0016] In addition, at least one of the first connecting part and the second connecting part is provided in multiple numbers, so that it can be switched and detached according to the first connecting state and the second connecting state.

[0054] This invention relates to an X-ray imaging device.

[0055] Hereinafter, an X-ray imaging device according to one embodiment of the present invention (hereinafter referred to as the 'present imaging device (1000)') will be described.

[0056] FIG. 1 is a drawing for explaining an X-ray imaging device according to one embodiment of the present invention.

[0057] FIG. 2 is a drawing for explaining a first connecting part and a second connecting part according to an embodiment of the present invention.

[0058] Referring to FIG. 1, the imaging device (1000) may include a column to which a generator (200) is rotatably connected and which is equipped with a first connecting part (111). At this time, the generator (200) may be rotatably connected to the left or right side of the column (110) through an extension part to be described later that is connected to the column (110).

[0059] At this time, the column (110) may be provided to face a third direction.

[0060] Here, the third direction may refer to the up and down direction as illustrated in FIG. 1.

[0061] Referring to FIG. 2, the first connecting part (111) may be provided to be connectable to the second connecting part (121) to be described later.

[0062] For example, the first connecting part (111) may be provided on the rear side of the column (110) or on the left and right sides of the column (110). The location where the first connecting part (111) is formed will be described in detail later.

[0063] Additionally, the imaging device (1000) may include an arm (120) having a second connecting part (121) coupled to a first connecting part (111) at one end. Here, the arm (120) may refer to a cephalometric arm.

[0064] At this time, the arm (120) can face the first direction as shown in FIG. 1.

[0065] In other words, the arm (120) can be configured to extend in a first direction, and the direction in which the arm (120) faces the other side of the first direction and the one side of the first direction can be changed through the first connection state and the second connection state described later. This will be explained in detail later.

[0066] Additionally, the imaging device (1000) may include a first sensor terminal (130) connected to the other end of the arm (120) and facing the generator (200).

[0067] At this time, the first sensor unit (130) can be mounted on an arm (120) that is coupled to an upper part of the column for cephalometric imaging and extends to the other side of the first direction.

[0068] In other words, the first sensor unit (130) may refer to a sensor unit with a built-in cephalometric detector.

[0069] Additionally, referring to FIG. 2 and FIG. 4, FIG. 10, FIG. 16, and FIG. 21 to be described later, a third connecting part (122) may be provided at the other end of the arm (120).

[0070] For example, the second connecting part (121) may be formed at least one of the front, rear, upper, and lower sides of the arm (120) on one side of the first direction of the arm (120).

[0071] Additionally, the third connecting part (122) may be formed at least one of the front, rear, upper, and lower sides of the arm (120) on the other side of the first direction of the arm (120). The formation locations of the second connecting part (121) and the third connecting part (122) will be described in detail later.

[0072] In addition, as described above, the second connecting part (121) may be provided to be coupled with the first connecting part (111).

[0073] Specifically, referring to FIGS. 18 and 19 to be described later, the first connecting part (111) and the second connecting part (121a, 121b) can be joined in a first direction.

[0074] For example, with reference to FIGS. 18 and 19 to be described later, as described above, the first connecting part (111a, 111b) is provided on the left side (other side of the first direction) and the right side (one side of the first direction) of the column (110), and the second connecting part (122) is formed on one side of the first direction of the arm (120) based on FIG. 18 to be described later, so that the first connecting part (111) and the second connecting part (121a, 121b) can be joined in the first direction.

[0075] Additionally, referring to FIGS. 4 and 7 to be described later, the first connecting part (111) and the second connecting part (121a, 121b) can be joined in a second direction.

[0076] For example, as described above, the first connecting part (111) is provided on the rear side (other side of the second direction) of the column (110), and the second connecting part (121a, 121b) is provided on the front side (one side of the second direction) and the rear side (other side of the second direction) at one end of the first direction of the arm (120), so that the first connecting part (111) and the second connecting part (121a, 121b) can be combined in the second direction.

[0077] The third connecting part (122) may be provided to be coupled with the fourth connecting part (131) to be described later.

[0078] Additionally, referring to FIGS. 4, 10, 16, and 21 to be described later, the first sensor unit (130) may be provided with a fourth connection unit (131) that is coupled to a third connection unit.

[0079] For example, the fourth connection part (131) may be formed at least one of the front, rear, and upper sides of the first sensor unit (130). The location of the formation of the fourth connection part (131) will be described in detail later.

[0080] In addition, as described above, the fourth connecting part (131) may be provided to be coupled with the third connecting part (122a, 122b).

[0081] At this time, the first connecting part (111) and the second connecting part (121) can be switched to the first connecting state and the second connecting state by detachable coupling or rotation, and the arm (120) extends to the left (left-hand type) or right (right-hand type) of the column (110) according to the first connecting state and the second connecting state, and the first sensor part (130) can face the generator (200) on the left or right side of the column (110) by rotation of the generator (200).

[0082] In addition, when the arm (120) of the imaging device (1000) is positioned on the left or right side of the column (110), the position or direction of the handle frame can be appropriately adjusted as needed for reasons such as the movement path of the subject.

[0083] In other words, it is desirable that the degree of connection between the first connecting part (111) and the second connecting part (121) be set to a level that allows for easy attachment and detachment and rotation when attachment and detachment and rotation are required.

[0084] Specifically, the first connecting part (111) and the second connecting part (121) may be provided as mutually rotatable connecting members.

[0085] For example, the first connecting part (111) and the second connecting part (121) are provided with a rotatable structure such as a hinge or link, so that the first connecting part (111) and the second connecting part (121) can rotate while connected to each other.

[0086] In addition, at least one of the first connecting part (111) and the second connecting part (121) is provided in multiple numbers and can be switched between the first connecting state and the second connecting state. In other words, it is preferable that the degree of connection between the first connecting part (111) and the second connecting part (121) be set to a level that allows for easy attachment and detachment and rotation when such adjustments are required.

[0087] For example, as described above, the first connecting part (111) may be provided on the rear side of the column (110) or on the left and right sides of the column (110), and the second connecting part (121) may be formed on at least one of the front, rear, upper, and lower sides of the arm (120) at one side of the first direction of the arm (120).

[0088] Specifically, the first connecting part (111) and the second connecting part (121) can be detachably coupled or rotated so that the arm (120) is rotated 180 degrees around the second direction or the third direction as an axis, depending on the first connection state and the second connection state.

[0089] Here, the first connection state may refer to a state in which the second connection part (121a 121b) formed on one side or the other side of the second direction among the first connection part (111) and the second connection part (121) is combined, with reference to FIGS. 3 to 15 to be described later.

[0090] Additionally, referring to FIGS. 16 to 29 described later, the second connection state may refer to a state in which the second connection part (121) formed on the side of the arm (120) (one side of the first direction based on FIG. 18) and the first connection part (111a, 111b) formed on the other side of the first direction or one side of the first direction of the column (110) are combined.

[0091] At this time, the process of switching to the first connection state and the second connection state will be described in detail later.

[0092] In addition, at least one of the third connecting part (122) and the fourth connecting part (131) is provided in multiple numbers and can be switched and detached according to the third connecting state and the fourth connecting state.

[0093] For example, the third connecting portion (122) may be formed at least one of the front, rear, upper, and lower sides of the arm (120) on the other side of the first direction of the arm (120). Additionally, the fourth connecting portion (131) may be formed at least one of the front, rear, and upper sides of the first sensor unit (130).

[0094] Here, referring to FIGS. 3 to 8 and FIGS. 16 to 22 to be described later, the third connection state may refer to a connection state in which the third connection part (122b, 122a) formed on the other side of the third direction or on one side of the third direction among the fourth connection part (131) and the third connection part (122) is combined.

[0095] Additionally, referring to FIGS. 9 to 15 and FIGS. 23 to 29 described later, the fourth connection state may refer to a state in which the third connection part (122a and 122b) formed on the second direction side and the second direction other side of the arm (120) at the first direction other end of the arm (120) and the fourth connection part (131) formed on the second direction other side of the first sensor end (130) are combined.

[0096] In addition, the third connecting part (122) and the fourth connecting part (131) may be connected to each other and may be configured to be detachable and rotatable from each other.

[0097] Accordingly, the third connecting part (122) and the fourth connecting part (131) may be able to switch to the third connecting state and the fourth connecting state by detachable coupling or rotation.

[0098] At this time, the process of switching to the third and fourth connection states will be described in detail later.

[0099] Specifically, the third connecting part (122) and the fourth connecting part (131) may be provided as mutually rotatable connecting members.

[0100] For example, the third connecting part (122) and the fourth connecting part (131) are provided with a rotatable structure such as a hinge or link, so that the third connecting part (122) and the fourth connecting part (131) can rotate while connected to each other. In other words, the arm (120) can change direction relative to the column (110) through the attachment and detachment of at least one of the first connecting part (111) and the second connecting part (121) and the attachment and detachment of the third connecting part (122) and the fourth connecting part (131).

[0101] Here, the change of direction of the arm (120) may refer to changing the position of the arm (120) from the left side (other side of the first direction) of the column (110) to the right side (one side of the first direction) of the column (110) with reference to FIGS. 7, 12, 19, and 25 to be described later. Specifically, the change of direction may include a first change in which the arm (120) changes direction by rotating 180 degrees around the second direction as an axis, and a second change in which the arm (120) changes direction by rotating 180 degrees around the third direction as an axis.

[0102] In other words, the first turning may mean that the arm (120) is set up so that the other side of the first direction of the arm (120) faces one side of the third direction, and then the arm (120) is positioned so that the other side of the first direction before the first turning faces one side of the first direction and rotated. That is, in the case of the first turning, the upper and lower surfaces of the arm (120) may be turned.

[0103] In other words, the first transition may mean vertical rotation, where the arm (120) is rotated vertically.

[0104] Additionally, the second transition may mean rotating the arm (120) while lying down so that the other side of the first direction of the arm (120) faces the other side of the second direction, and then rotating the arm (120) by positioning it so that the other side of the first direction before the second transition faces the one side of the first direction. That is, in the case of the second transition, the front and rear sides of the arm (120) may be transitioned.

[0105] In other words, the second transition may mean horizontal rotation of the arm (120).

[0106] FIG. 3 is a drawing for explaining that, according to one embodiment of the present invention, an arm is coupled to the other side of the column in the second direction and coupled to the first sensor end in the third direction, and FIG. 4 is a drawing for explaining that, according to one embodiment of the present invention, the coupling of the arm and the column of FIG. 3 and the coupling of the arm and the first sensor end are released.

[0107] Additionally, referring to FIGS. 3 and 4, the first connecting part (111) described above may be formed on the other side of the second direction of the column (110), the second connecting part (121) may be formed on one side of the first direction of the arm, and formed on one side of the second direction of the arm and the other side of the second direction of the arm, the third connecting part (122) may be formed on the other side of the first direction of the arm, and formed on one side of the third direction of the arm and the other side of the third direction of the arm, and the fourth connecting part (131) may be formed on one side of the third direction of the first sensor section.

[0108] At this time, the column (110) and the arm (120) can be combined through the first connection state, with the second connection part (121a) formed on one side of the second direction among the first connection part (111) and the second connection part (121).

[0109] Additionally, the first sensor unit (130) and the arm (120) can be combined through a third connection state with a third connection part (122b) formed on the other side of the third direction among the fourth connection part (131) and the third connection part (122).

[0110] Specifically, as described above, referring to FIGS. 3 and FIGS. 4, a first connecting part (111) may be formed on the rear side (second direction other side) of the column (110).

[0111] Additionally, referring to FIGS. 3 and 4, a second connecting part (121) corresponding to the first connecting part (111) may be formed on one side of the first direction among the rear side (second direction other side) and the front side (second direction one side) of the arm (120).

[0112] At this time, the first connecting part (111) and the second connecting part (121) may be configured to be coupled to each other, and through the first connecting state, the second connecting part (121a) formed on the front side (one side of the second direction) of the arm (120) among the second connecting parts (121) of the arm (120) and the first connecting part (111) may be coupled. Accordingly, the arm (120) and the column (110) may be coupled to each other at the front side of the arm (120) (specifically, one side of the first direction among the front sides of the arm (120)) and the rear side (other side of the second direction) of the column (110).

[0113] Additionally, referring to FIGS. 3 and 4, a third connecting part (122a, 122b) may be formed on the other side of the first direction among the upper surface (one side of the third direction) and lower surface (other side of the third direction) of the arm (120).

[0114] Additionally, referring to FIGS. 3 and 4, a fourth connection part (131) may be formed on the upper surface (one side of the third direction) of the first sensor unit (130) to correspond to the third connection part (122).

[0115] At this time, referring to FIGS. 3 and 4, the third connecting part (122) and the fourth connecting part (131) can be provided to be coupled to each other, and through the third connecting state, the third connecting part (122b) formed on the lower surface (third direction other side) of the arm (120) among the third connecting parts (122) of the arm (120) and the fourth connecting part (131) can be coupled. Accordingly, the arm (120) and the first sensor unit (130) can be coupled to each other on the lower surface of the arm (120) (specifically, the first direction other side among the lower surfaces of the arm (120)) and the upper surface (third direction one side) of the first sensor unit (130).

[0116] In other words, referring to FIGS. 3 and 4, one end of the arm (120) can be connected to the rear surface (second direction side) of the column (110) and the other end can be connected to the upper surface (third direction side) of the first sensor section (130).

[0197] Additionally, referring to FIGS. 28 and 29, when the arm (120) and the column (110) are connected through the second connection state, if the arm (110) rotates 180 degrees around the third direction as a second transition, the connection between the second connection part (121) and the first connection part (111b) formed on the other side of the first direction among the first connection part (111) is released, and after the arm (120) rotates 180 degrees around the third direction as a axis, the second connection part (121) can be connected to the first connection part (111b) formed on one side of the first direction among the first connection part (111), and through the third connection state, the connection between the arm (120) and the first sensor unit (130) is released between the fourth connection part (131) and the third connection part (122a) formed on one side of the second direction among the third connection part (122), and the fourth The connecting part (131) can be combined with a third connecting part (122b) formed on the other side of the second direction (based on before the arm (120) rotates, based on FIG. 25).

[0198] That is, with reference to FIGS. 28 and FIGS. 29, the arm (120) rotates horizontally relative to the column (110) so that the front (one side of the second direction) and the rear (other side of the second direction) of the arm (120) are switched, and the second connecting part (121) is released from the connection with the first connecting part (111b) formed on the other side of the first direction of the column (110) before the first switch, and the second connecting part (121) can be connected to the first connecting part (111a) formed on the one side of the first direction of the column (110) among the first connecting parts (111), and the fourth connecting part (131) is released from the connection with the third connecting part (122a) formed on the front (one side of the second direction) of the arm (120) before the second switch, and can be connected to the third connecting part (122b) formed on the rear (other side of the second direction) among the third connecting parts (122) before the second switch.

It is possible.

[0200] Additionally, the imaging device (1000) may include an extension part (300) connected to a column (110) and rotatably connected to a generator (200).

[0201] At this time, the generator (200) may be rotatably provided with respect to the extension.

[0202] Specifically, as described above, when the arm (120) is switched left and right through the first and second switching, the generator (200) is rotatably provided with respect to the extension so as to be rotated to face the first sensor unit (130).

[0203] In other words, the generator (200) can be provided to rotate independently with respect to the extension. That is, the generator (200) can rotate around the extension and move to a position always opposite to the first sensor unit (130) depending on the left or right turn of the arm (120).

[0204] Accordingly, when the arm (120) is extended to the left or right according to the first connection state and the second connection state, the generator (200) can rotate around the extension part to maintain a facing relationship with the first sensor unit (130).

[0206] Accordingly, when a subject is aligned between the generator (200) and the second sensor unit (330), the generator (200) and the second sensor unit (330) face each other, and the gantry (320) rotates around the axis of rotation between them to take an X-ray panoramic or CT image. To this end, the second sensor unit (330) may be equipped with a CT detector for CT imaging and / or a panoramic detector for X-ray panoramic imaging. Then, when the subject moves and aligns to the first sensor section (130) of the arm (120) extended to the left or right of the column (110), the gantry (320) and the generator (200) rotate so that the generator (200) faces the first sensor section (130) on the left or right side of the column (110), and in this state, an X-ray cephalometric image can be taken using the generator (200) of the gantry (320) and the cephalometric detector of the first sensor section (130).
