Thus, unless otherwise indicated, the features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present application.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the application may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" over … …, "" upper, "" over … …, "" upper "and" side (e.g., as in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture.

According to one embodiment of the present application, an oral CT apparatus is provided. Fig. 1 and 2 illustrate an oral CT apparatus according to an embodiment of the present application.

As shown in fig. 1 and 2, the oral CT apparatus may include a source 100, a detector 200, a support arm 300, and a driving device 400.

The source 100 may be used to emit X-rays and the detector 200 may be used to receive X-rays. The source 100 and detector 200 are disposed opposite and spaced apart a predetermined distance. An accommodating space is formed between the oppositely disposed and spaced-apart source 100 and detector 200, in which an object to be measured, such as a patient's head, can be accommodated. The object to be measured thus accommodated in the accommodation space can be irradiated with the X-rays emitted from the source 100 and received by the detector 200, thereby achieving photographing of the object to be measured.

The support arm 300 may be used to support and retain the source 100 and detector 200. Source 100 and detector 200 may be secured to support arm 300. As shown, support arm 300 may be generally C-shaped. As one example, support arm 300 may include a first portion 310, a second portion 320, and a third portion 330. Wherein the first portion 310 extends in a vertical direction, and the second and third portions 320, 320 extend in a lateral direction.

In the present application, the vertical direction may be the Y direction shown in the drawing, which may be a direction perpendicular to a supporting surface (setting surface) on which the oral CT apparatus is set, or may be regarded as a direction perpendicular to a plane of a housing to be described below; the lateral direction may be the X direction shown in the drawing, which may be a direction parallel to a support surface provided to the oral CT apparatus, or may be regarded as a direction parallel to a plane of a housing to be described below. The directions in which the vertical direction and the lateral direction may intersect, for example, may intersect at 90 degrees.

The first portion 310, the second portion 320, and the third portion 330 may be integrally formed or may be fixedly formed. The second portion 320 and the third portion 330 may be disposed near both ends of the first portion 310. The second portion 320 may have the detector 200 secured thereto and the third portion 330 may have the source 100 secured thereto, thereby forming the detector 200 and the source 100 disposed opposite each other in the vertical direction.

The drive 400 may include a drive motor 410 and a hollow rotating platform 420. Hollow rotating platform 420 is a conventional technology in the art and will not be described in detail herein. The drive motor 410 may be used to drive the hollow rotary platform 420, and the hollow rotary platform 420 is connected to the first portion 310 of the support arm 300 by a connecting shaft. Wherein the second portion 320 and the third portion 330 are disposed on a first side of the first portion 310 and the driving device 400 is disposed on a second side of the first portion 310.

In this way, the rotation of the driving motor 410 of the driving device 400 rotates the hollow rotating platform 420, so as to drive the supporting arm 300 to rotate, and finally, the rotation of the source 100 and the detector 200 is realized. In the present application, the rotation of the source 100 and detector 200 is a circular motion in a plane perpendicular to the horizontal plane.

A bracket 500 may also be included in the present application. A bracket 500 may be used to support the drive apparatus 400, for example, a hollow swivel platform 420 may be mounted on the bracket 500 to support the drive apparatus 400.

The oral CT apparatus according to the present application is different from the existing suspended oral CT apparatus and the floor-type oral CT apparatus. A downward opening accommodating space is formed in the suspended oral CT device for accommodating a patient, and a rotating mechanism is arranged above the head of the patient, so that the source and the detector rotate on two sides of the head of the patient, and shooting is completed. The floor type oral cavity CT equipment is characterized in that an accommodating space with an upward opening is formed to accommodate a patient, and a rotating mechanism is arranged at the lower part of the patient, so that a source and a detector are arranged at two sides corresponding to the head of the patient, and the source and the detector rotate at two sides of the head of the patient, thereby completing shooting. The oral CT device of the application forms a lateral opening accommodating space for accommodating the head of a patient. The oral CT apparatus of the present application is thus in a form that differs significantly from the oral CT apparatus of the prior art.

Fig. 3 to 6 show partial schematic views of an oral CT apparatus according to an embodiment of the present application. As shown, the source 100 may be secured to the first portion 310 by a third portion 330, wherein the third portion 330 may be in the form of a source holder, and the detector 200 may be secured to the first portion 310 by a second portion 320, wherein the second portion 320 may be in the form of a detector holder. The driving motor 410 may be mounted to one side of the hollow rotary platform 420, and the connection shaft 430 may be mounted to the other side of the hollow rotary platform 420, and a mounting hole is provided on the first portion 310 for mounting the connection shaft 430.

As shown in fig. 1 and 2, the oral CT apparatus of the present application may further include a support table 600, and the stand 500 may be fixedly mounted to the support table 600 so as to support components such as a driving device, a support arm, a source, and a detector. A housing 700 may also be included. Wherein the base 700 may be used to fix and support the support table 600. Although the support table and the base are shown in the drawings, they may be integrally formed or only the base may be provided. The upper surface of the base 700 functions as a support stand.

Fig. 7 illustrates an oral CT apparatus according to one embodiment of the present disclosure. As shown, the stand 500 is slidable with respect to the base 700 (hereinafter, a description will be given of an example in which a support stand is not provided, and if a support stand is present, the stand is operated and mounted with respect to the support stand). For example, the sliding guide mechanism may be provided to the base or opposite the base. A guide rail 800 is fixedly provided to the seat body 700 (support base). As shown, the number of the guide rails may be two and disposed at both sides of the bracket 500, respectively. Wherein the rail 800 extends in a horizontal direction. A chute 510 may be provided at a lower portion of the bracket 500, the chute 510 being slidably mounted to the guide rail 800 and allowing the chute 510 to move along the guide rail 800.

In order to enable the chute 510 to move along the guide rail 800, a driving motor (not shown in the drawing) may be provided. Thus, during photographing of the object, the driving motor 410 may control the rotation of the source 100 and the detector 200 in a circular motion, and the driving motor may control the movement of the source 100 and the detector 200 in a linear motion. Wherein the source 100 and detector 200 are moving along in a horizontal plane.

In the present application, the bottom of the bracket 500 may be fixed to the upper side of the mounting plate 520, and the chute 510 may be fixed to the lower side of the mounting plate 520, and the bracket is moved by the movement of the mounting plate 520, thereby finally moving the source 100 and the detector 200.

According to the oral cavity CT equipment disclosed by the application, the operation mode is different from that of the traditional oral cavity CT equipment, and a novel operation mode is provided subvertly. The oral CT device can laterally and rotationally control the source and the detector (namely, rotationally control one side of a tested object), and the source and the detector are oppositely arranged in the vertical direction. In this way, more space is left for the tested object on one side, and the control of the application is more convenient and simpler

The oral CT equipment innovatively designed according to the application provides more various measuring modes. As shown in fig. 8 and 9, the oral CT apparatus of the present application may use a sitting type measurement or a lying type measurement (or a lying type measurement).

Fig. 8 shows a schematic view of an oral CT device of the present application with some components added that can be used for sitting measurements.

As shown in fig. 8, when a sitting measurement is performed, a chest abutment 910 may be installed so that after the patient sits on a chair, the chest may be rested on the chest abutment 910, thereby securing the patient's body.

The chest abutment 910 may be connected to the base 700 by a connector 920, thereby functioning to secure the chest abutment 910. A handle 930 may also be provided on the connector 920 for grasping by the patient. In sitting measurements, a head positioning device 940 may also be included, which head positioning device 940 may be secured to the chest abutment 910 and may support the forehead and chin of the patient's head to achieve positioning.

In the case of a sitting measurement, after the patient is in place, the source and detector are controlled to rotate about the patient's head, which is a circumferential rotation perpendicular to the horizontal, and the source and detector may also be controlled to move in the horizontal direction.

Fig. 9 shows the case where the oral CT apparatus of the present application is used for a lying measurement (or a lying measurement). In this case, the measuring bed may be directly provided in correspondence with the oral CT apparatus. So that the patient can lie on the measuring bed or lie on the measuring bed and the head can be located between the source and the detector. After the patient is in place, the source and detector are controlled to rotate about the patient's head, which is a circumferential rotation perpendicular to the horizontal, and the source and detector may also be controlled to move in the horizontal direction.
