Description

Technical Field

[0001] The utility model relates to the technical field of oral CT, in particular to a radiation source column of a floor-standing oral CT system. Background Art

[0002] Imaging technologies, including X-ray imaging, CT (Computed Tomography), etc., have been widely used in many fields since their introduction, especially in the field of medical examination. Oral CT can reflect the tissue condition from a three-dimensional perspective and can detect lesions that cannot be detected by the projection angle of oral X-rays or are more subtle. Usually, oral CT is equipped with an X-ray source and a detector that can emit a cone beam.

[0003] The frame columns of oral CT machines currently on the market are basically single-cantilever structures, with a rotatable C-arm device installed under the cantilever, which drives the C-arm device to rotate through the swivel device. The X-ray emitting device (source) is installed at one end of the C-arm device. This traditional combined structure of a single cantilever and a C-arm device not only has a high center of gravity and a vibration amplification effect, but also causes large vibrations when the machine is working, and the stability of the imaging cannot be guaranteed. In addition, the frame columns of this traditional oral CT have a small cross-sectional size and a narrow internal space, so it is difficult to lay out electronic devices inside the column. Moreover, the X-ray emitting device of the C-arm device is very close to the patient's head, and the C-arm device is prone to hit the patient's shoulders and other body parts when rotating.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0030] like Figures 1 to 4As shown, the present embodiment proposes a radiation source column of a floor-standing oral CT system, including a base 10, a radiation source column 20, a radiation source and a detection assembly, wherein the radiation source column 20 is arranged on one side of the top of the base 10, the radiation source is arranged on the top of the radiation source column 20, and the detection assembly is arranged on the other side of the top of the base 10. Specifically, the radiation source column 20 includes two side plates 210, a plurality of horizontal plates 220 and two vertical plates 230, the two side plates 210 are arranged opposite to each other, and the plurality of horizontal plates 220 are arranged between the two oppositely arranged side plates 210, and the two vertical plates 230 are also arranged between the two side plates 210, and the detection assembly includes a detector column 90 and a detector 910, the detector column 90 is installed at one end of the base 10 away from the radiation source column 20, and the detector 910 is installed on the top of the detector column 90;

[0031] When a patient needs to undergo an oral CT scan, he or she can stand on the base 10, and the base 10 drives the source column 20 and the detector column 90 on both sides thereof to rotate relative to each other, so that the source can emit X-rays from different directions toward the patient's face. At this time, the detector 910 can receive the X-rays passing through the patient's face and perform imaging processing, and then examine the patient. Because the source column 20 and the detector column 90 are both located on both sides of the patient, the equipment space is large, and the source column 20 and the detector column 90 will not collide with the patient's body when rotating, thereby improving safety. In addition, the source column 20 composed of the side plate 210, the horizontal plate 220 and the vertical plate 230 has an internal A semi-enclosed cavity can be formed, and in order to increase the installation space inside the two side panels 210, the number of transverse panels 220 can be set to 10 groups, and they can be installed equidistantly between the two side panels 210, so that each transverse panel 220 can form an inner cavity with the side panels 210. Therefore, compared with the columns in the prior art, the internal space of the source column 20 in the present application is greatly increased, so that it is convenient to install and arrange various electrical components, wiring harnesses and structural units used in the oral CT equipment, and the source column 20 composed of the side panels 210, the transverse panels 220 and the vertical panels 230 has high stability, which can also improve the stability of the source installation and imaging in the oral CT imaging system.

[0032] Among them, the inner wall of the side plate 210 is provided with a plurality of mounting sleeves 211 and mounting heads 212, the side wall of the mounting sleeve 211 is provided with a slot matching with the cross plate 220, and the surface of the mounting head 212 is provided with a positioning hole; by inserting the cross plate 220 into the slot of the side wall of the mounting sleeve 211, it is convenient to quickly install and disassemble the cross plate 220, and the mounting head 212 is provided with the positioning hole to facilitate the installation of the external shell on the source column 20 to shield and protect the inner cavity.

[0033] In addition, the side panels 210, the horizontal panels 220, the vertical panels 230, the mounting sleeves 211 and the mounting heads 212 are connected by mortise and tenon joints and welding, which can improve the strength, rigidity and stability of the assembled radiation source column 20, thereby preventing the radiation source column 20 from shaking when the equipment is working, resulting in unstable radiation source imaging.

[0034] It should be noted that when the equipment is produced, a "source focus" mark that is on the same axis as the source can be printed on the bottom of the side panel 210 through a laser marking process; the projection mark shows the position of the source focus in the vertical direction and located on the source column 20, which is convenient for subsequent measurement of the distance between the source focus and the center of rotation of the equipment.

[0035] Then, a “→” mark is printed on the horizontal plate 220 at the bottom of the side plate 210 by laser marking, which is convenient for the calibration work of returning the radiation source column 20 to the original position in the floor-standing oral CT system.

[0036] In order to facilitate the neat installation of electrical circuits in CT equipment, Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the surfaces of the side panels 210, the horizontal panels 220 and the vertical panels 230 are provided with a plurality of wiring harness openings 30 of different shapes and sizes; the wiring arrangement of various electrical components in the CT device is facilitated by the plurality of wiring harness openings 30.

[0037] A wiring harness routing groove 40 connected to the inside of the base 10 is formed between the side plate 210 and the vertical plate 230 , so as to facilitate the routing of communication lines inside the radiation source column 20 and the inside of the base 10 .

[0038] Slots 50 are provided on both sides of the horizontal plate 220 at the top of the side plate 210 , which facilitate the connection of the radiation source circuit installed on the top of the radiation source column 20 .

[0039] A plurality of threaded holes 60 are provided on the surfaces of the side plates 210 , the horizontal plates 220 and the vertical plates 230 ; various electrical components can be arranged and installed through the threaded holes 60 in conjunction with bolts.

[0040] like Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the side wall of the horizontal plate 220 at the bottom of the side plate 210 is provided with two openings of the connecting flange 70, and the surface of a horizontal plate 220 of the side plate 210 located above the bottom horizontal plate 220 is provided with a C-shaped avoidance hole 80 corresponding to the connecting flange 70;

[0041] By means of the connecting flange 70, the horizontal plate 220 at the bottom of the side plate 210 can be installed on the wire trough of the base 10, so as to facilitate the laying of communication lines in the base 10 and the radiation source column 20. When the bolts are passed through the openings on the connecting flange 70 to tighten the connecting flange 70, the C-shaped avoidance holes 80 can be used to allow the horizontal plate 220 to avoid the bolts to prevent affecting the screwing-in of the bolts.

[0042] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, a plurality of mounting holes 221 are opened on the surface of the horizontal plate 220 at the bottom end of the side plate 210, and a plurality of circular avoidance holes 222 corresponding to the mounting holes 221 are opened on the surface of a horizontal plate 220 located above the horizontal plate 220 at the bottom end of the side plate 210;

[0043] The horizontal plate 220 at the bottom of the side plate 210 is abutted against the base 10, and then bolts are passed through the mounting holes 221 and screwed into the fixing holes on the base 10, so that the radiation source column 20 and the base 10 can be installed and fixed. The circular avoidance holes 222 can avoid the bolts and avoid affecting the screwing-in of the bolts, thereby facilitating the installation of the radiation source column 20.

[0044] Among them, the side of the horizontal plate 220 at the bottom of the side plate 210 opposite to the base 10 is an arc-shaped structure; because the base 10 is a circular structure, when the horizontal plate 220 at the bottom of the side plate 210 contacts the side wall of the base 10, the horizontal plate 220 with the arc-shaped structure can fit the side wall of the base 10 more closely, thereby facilitating the stable installation of the radiation source column 20 and the base 10.

[0045] Working principle of the utility model: when a patient needs to undergo oral CT scanning, he can stand on the base 10, and the base 10 drives the radiation source column 20 and the detector column 90 on both sides thereof to rotate relative to each other, so that the radiation source can emit X-rays from different directions toward the patient's face. At this time, the detector 910 can receive the X-rays passing through the patient's face and perform imaging processing, so as to realize the oral examination of the patient. Because the radiation source column 20 and the detector column 90 are both located on both sides of the patient, the equipment space is relatively large, and the radiation source column 20 and the detector column 90 are relatively large. The column 90 will not collide with the patient's body when rotating, thereby improving safety; and the radiation source column 20 composed of the side panels 210, the horizontal panels 220 and the vertical panels 230 can form a semi-enclosed cavity inside, thereby facilitating the installation and arrangement of various electrical components, wiring harnesses and structural components used in the oral CT equipment; and the radiation source column 20 composed of the side panels 210, the horizontal panels 220 and the vertical panels 230 through mortise and tenon joints and welding has high strength, rigidity and stability, thereby also improving the stability of radiation source installation and imaging in the oral CT imaging system.

[0046] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
