Description

Floor type CT device

Technical Field

The present disclosure relates to a floor type CT apparatus

Background

Imaging techniques such as X-ray imaging, CT (Computed Tomography ) and the like have been widely used since their advent in numerous fields, particularly in the field of medical examinations.

The oral cavity CT machines in the market at present are basically of single cantilever type structures, a rotatable device is arranged below a cantilever, and the rotatable device is connected with a rotating arm. Because the single cantilever itself has vibration amplification effect, serious shaking can occur when the machine runs, the imaging stability can not be ensured, the single cantilever itself has no stability, the single cantilever itself can keep balance only by the counterweight, and some auxiliary fixing needs to be additionally added, so that the installation is inconvenient, and the whole machine can not move after the installation is finished. In addition, conventional oral CT machine internals are typically provided with drive circuitry (e.g., for driving the rotating arm in rotation) and circuitry for performing other functions. In practical application, the wiring of each circuit is prevented from being exposed to external components as much as possible, but the wiring arrangement of various circuits of the internal components of the oral cavity CT is complicated and complicated because the vertical fixing frame and the rotating arm are far away from the ground. Furthermore, since the source and detector are fixed to the rotating arm, the provision of electrical wiring for the source and detector is relatively complex.

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

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 present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., as in "sidewall"), etc., 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. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.
