AI Technical Summary
In current CT scans, the overlap between the thyroid gland and shoulder structures leads to insufficient radiation, resulting in artifacts that affect image quality. Furthermore, existing anti-artifact mechanisms cannot effectively adjust the degree of head tilt and shoulder fixation, resulting in unsatisfactory artifact elimination effects.
A neck CT saline anti-artifact support device was designed. By placing the patient's neck on a neck sponge pillow and injecting physiological saline into a transparent reservoir bag, along with adjustment and insert components, the shoulder is pressed down and the head is raised to ensure complete exposure of the neck. The physiological saline is used to compensate for tissue homogeneity and reduce artifacts.
It effectively reduces or eliminates X-ray artifacts around the thyroid gland, improves CT imaging quality, and enhances tissue homogeneity and image reconstruction effect through the homogeneity compensation of physiological saline.

[0028] Referring to Figures 1-5As shown, the utility model provides a kind of neck CT brine anti-ghost support device, including bottom plate 1, the upper surface of bottom plate 1 is fixedly connected with slope face backing plate 2, the upper surface middle part of slope face backing plate 2 is fixedly connected with neck sponge pillow 6, and the end surface middle part of slope face backing plate 2 is fixedly connected with the backing pillow 7 compatible with neck sponge pillow 6, and backing pillow 7 is located below neck sponge pillow 6, the both sides of neck sponge pillow 6 are equipped with the vertical column 8 fixedly connected with the surface of slope face backing plate 2, the opposite surface of two the vertical column 8 is equipped with the arc plate 9 compatible with neck curve, the opposite surface of two arc plate 9 is integrally formed with transparent liquid storage bag 10, and physiological saline is filled in transparent liquid storage bag 10, the upper side of two vertical column 8 is equipped with the sliding fixing piece for adjusting the position of arc plate 9, the side of two vertical column 8 away from the center of slope face backing plate 2 is fixedly connected with extension arm 11, the upper side of two the extension arm 11 is equipped with the clasp 12 for fixing the position of lower jaw, and the upper surface of two extension arm 11 is equipped with the sleeve assembly 5 for fixing the end of clasp 12 Position, the upper surface of slope face backing plate 2 is placed with two adjusting cross columns 13, and two adjusting cross columns 13 are located at the opposite side of two vertical column 8 respectively, and the end of two adjusting cross columns 13 towards the middle part of slope face backing plate 2 is fixedly connected with shoulder pressing inclined plate 14, and the both sides of the upper surface of slope face backing plate 2 are equipped with the adjusting assembly 4 for moving adjusting cross column 13.
[0029] As an optional implementation, the transparent liquid storage bag 10 is made of elastic silica gel, and the end of the transparent liquid storage bag 10 is integrally formed with a liquid injection nozzle 17. A sealing cover 18 is threadedly connected to the liquid injection nozzle 17. Physiological saline can be filled into the transparent liquid storage bag 10 through the liquid injection nozzle 17. The silica gel material has a certain ductility, which can make the transparent liquid storage bag 10 filled with saline better fit the neck curve.
[0030] Referring to Figure 3 As shown, the sliding fixing piece includes a square hole 16 opened above the vertical column 8. The middle part of the arc plate 9 is fixedly connected with a square slide rod 15 slidably connected with the square hole 16. The upper end of the vertical column 8 is provided with a plug-in assembly 3 for fixing the position of the square slide rod 15. The plug-in assembly 3 includes a latch hole 3a opened in the upper end surface of the vertical column 8 and communicated with the square hole 16. A latch 3b is inserted into the latch hole 3a. A plurality of positioning holes 3c are opened in the upper surface of the square slide rod 15 and inserted with the latch 3b. The upper end of the latch 3b is fixedly connected with a counterweight plate 3d.

A plurality of insertion rods 5a are fixedly connected to the inclined surface on the upper surface of the extension arm 11 and are inserted into the sleeve pipes 5b. By designing the downward inclination, the lap belt 12 can be more closely fitted to the head when fixing the lower jaw, so as to achieve better fixing effect. By inserting the sleeve pipes 5b at both ends of the lap belt 12 into the insertion rods 5a at appropriate positions, the positions of both ends of the lap belt 12 can be adjusted, so as to adjust the fixing angle of the lap belt 12 to the lower jaw.
[0032] Referring to Figure 5 As shown, the adjusting assembly 4 includes a mounting seat 4a fixedly connected to the upper surface of the slope supporting plate 2. A threaded rod 4b is rotatably connected in the mounting seat 4a. The adjusting cross column 13 is provided with a threaded hole 4c which is threadedly connected with the threaded rod 4b. The adjusting cross column 13 is designed in a square shape and is gap-fitted with the surface of the slope supporting plate 2. By rotating the threaded rod 4b, the adjusting cross column 13 which is threadedly connected with the threaded rod 4b is translated on the surface of the slope supporting plate 2, so as to drive the shoulder pressing inclined plate 14 to press and fix the two sides of the shoulder. By gap-fitting the adjusting cross column 13 with the surface of the slope supporting plate 2, the threaded rod 4b can be prevented from rotating the adjusting cross column 13 together when rotating, so as to smoothly threadedly connect the adjusting cross column 13 and to make the adjusting cross column 13 more stably move on the surface of the slope supporting plate 2.
[0033] By adopting the above structure, after the bottom plate 1 is installed on the CT bed and the patient lies on the bed in a supine position, the neck is located above the neck sponge pillow 6. Due to the height difference between the slope supporting plate 2 and the bottom plate 1, the back of the head is naturally raised and attached to the supporting pillow 7. Then the lap belt 12 is wrapped around the lower jaw. Then the positions of both ends of the lap belt 12 are fixed by the sleeve assembly 5, so as to drive the lower jaw to be fully raised. Then the positions of the two arc-shaped plates 9 are moved, so as to make the two arc-shaped plates 9 respectively located at both sides of the neck. Then the two adjusting cross columns 13 are moved by the adjusting assembly 4. After the shoulder pressing inclined plate 14 contacts with the two sides of the shoulder, the two sides of the shoulder are respectively pressed down and closely fitted with the slope supporting plate 2 under the wedge-shaped cooperation, so as to completely open the shoulder clavicle. Then physiological saline is respectively injected into the two transparent liquid storage bags 10, so as to be inflated and closely fitted with both sides of the neck. Then CT irradiation can be performed.
[0034] Because the transparent liquid storage bag 10 contains physiological saline, the bag body is just located at the neck and shoulder of the patient and can perfectly fit the external curve of the neck and shoulder of the patient. Because of the physiological saline, compensation of the detected tissue can be carried out, and uniformity of the tissue is improved, that is, the physiological saline plays a role of uniformity of tissue attenuation in image reconstruction, that is, whether it is human bone or human muscle, because the physiological saline is covered, the whole detected tissue is more uniform. At this time, CT detection is carried out again, and the ray beam hardening artifact at the junction of the neck and the chest is obviously improved, and the ray beam artifact around the thyroid is effectively reduced or even eliminated.
[0035] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
