[0002] When performing neck CT scans, such as thyroid CT and head and neck CTA examinations, beam hardening artifacts often occur due to the complexity of the anatomical structure at the junction of the neck and the thoracic inlet. In addition, when performing neck MR examinations, the difference in air and tissue density often leads to a decrease in the signal-to-noise ratio. These problems seriously affect the diagnostic quality of the images. Therefore, in order to improve the image quality of head and neck CT and MR examinations, an auxiliary device that can effectively reduce artifacts and improve the signal-to-noise ratio is needed.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] See attached Figure 1-3 A portable filled neck sleeve includes a neck coat. The overall structure of the neck coat is U-shaped. The U-shaped design fits the human neck better and is used to better fit the back and sides of the patient's neck to reduce the air-soft tissue contact area. A neck inner sleeve is also provided in the neck coat. The neck coat is filled with a filling material for improving the uniformity of the local magnetic field. In this application, the filling material specifically uses rice and saline with a magnetic susceptibility similar to that of the human body.

[0023] In this embodiment, the neck coat comprises a lower coat 1 and an upper coat 5. The lower coat 1 is symmetrically connected to the upper coat 5. The opening edge of the lower coat 1 and the opening edge of the upper coat 5 are closed and sewn by needle and thread, that is, a closed space is formed between the lower coat 1 and the upper coat 5 for filling rice. The lower coat 1 and the upper coat 5 in this application are specifically made of medical cotton cloth. After the rice is filled between the lower coat 1 and the upper coat 5, the excess air between the lower coat 1 and the upper coat 5 can be passed through the lower coat 1 made of medical cotton cloth. The reason for filling with rice is: the magnetic susceptibility of rice is -8.2×10 -7 emu, the magnetic susceptibility of the cell cytoplasm is -7.2×10 -7 emu, the magnetic susceptibility of water that makes up the human body is -7.2×10 -7emu, that is, the magnetic susceptibility of rice is similar to that of the human body, which can suppress the uneven magnetic field occurring in the neck.

[0024] In this embodiment, the neck inner sleeve and the neck outer sleeve have the same shape. The filled neck inner sleeve can also be filled with the neck outer sleeve. The neck inner sleeve includes a lower inner sleeve 3 and an upper inner sleeve 4 which are symmetrical up and down. The opening edge of the lower inner sleeve 3 and the opening edge of the upper inner sleeve 4 are closed and connected. The upper inner sleeve 4 is overlapped and installed on the inner wall of the upper outer sleeve 5 by glue, that is, rice can only be filled between the neck inner sleeve and the lower outer sleeve 1. A strip slit 14 is reserved on one side of the lower outer sleeve 1. A closed-end zipper 2 is fixedly installed in the strip slit 14. The closed-end zipper 2 is used to quickly open and close the strip slit 14.

[0025] In this embodiment, the lower inner sleeve 3 and the upper inner sleeve 4 in the present application are made of rubber and have good sealing performance. The lower inner sleeve 3 and the upper inner sleeve 4 are mainly used to fill physiological saline with a magnetic susceptibility similar to that of the human body. The two ends of the upper inner sleeve 4 are respectively provided with a circular hole 7 and a circular hole 3 9, and the two ends of the upper outer sleeve 5 are respectively provided with a circular hole 2 8 and a circular hole 4 10. The circular hole 2 8 is connected to the top of the circular hole 7, and the circular hole 4 10 is connected to the top of the circular hole 3 9. The inner walls of the circular holes 1 7 and 2 8 are fixedly connected with a water injection pipe 12, and the upper end of the water injection pipe 12 is threadedly connected with a wire. The cover 13, the inner walls of the circular hole three 9 and the circular hole four 10 are fixedly connected with a transparent cover 11, which is made of transparent plastic and is used to collect gas. The water injection pipe 12 is used to fill the lower inner sleeve 3 and the upper inner sleeve 4 with saline. When the present application is put on the patient's neck, the two ends of the neck jacket are located in front of the body. When the patient lies on the CT scanning bed, the water injection pipe 12 and the transparent cover 11 are arranged above the neck jacket to collect the air in the neck jacket. The transparent cover 11 can also observe the amount of residual air in the inner neck jacket.

[0026] In this embodiment, two protrusions 6 are symmetrically installed on the upper coat 5. The protrusions 6 are also composed of a cloth cover made of medical cotton cloth and rice. The rice is filled inside the cloth cover and is attached to the upper coat 5 by Velcro. The two protrusions 6 can also be fitted on both sides of the neck to assist in positioning the patient's neck and increase the fit to the neck skin, reduce the air-soft tissue contact area, improve the local magnetic field uniformity, reduce the local magnetic susceptibility difference, and reduce DWI artifacts.

[0027] According to the utility model, when a patient undergoes CT and MR examination of the head and neck, rice having an X-ray attenuation coefficient close to that of human soft tissue is used to fill the neck outer sleeve, or physiological saline is used to fill the neck inner sleeve, and then the neck outer sleeve is filled with the neck inner sleeve. The U-shaped neck outer sleeve fits more closely to the back and both sides of the human neck, and the rice or physiological saline filled inside can produce a uniform response in the magnetic field to reduce beam hardening artifacts caused by the complexity of the anatomical structure. At the same time, two protrusions 6 are used to limit the fit pads on both sides of the neck, which can also reduce the contact area between the air and the skin on both sides of the neck, and further reduce the magnetic susceptibility difference of the air-soft tissue interface, improve the local magnetic field uniformity, reduce the local magnetic susceptibility difference, reduce DWI artifacts, and utilize the tissue shimming effect of the filling material to enhance the magnetic field uniformity of the examination area, thereby improving the signal-to-noise ratio of the MR image, thereby improving the accuracy and reliability of the diagnosis.

[0028] The present application can be filled with liquid saline or solid rice particles, and is more flexible to use. By opening the wire cover 13 on the water injection pipe 12, the saline in the lower inner sleeve 3 and the upper inner sleeve 4 can be discharged, or the strip slit 14 can be opened through the closed-end zipper 2 to discharge the rice filled between the lower outer sleeve 1 and the neck inner sleeve, making the present application more portable and more convenient to carry. In addition, the medical cotton cloth, rubber, rice and saline used in the present application can be widely used in different models of CT and MR equipment, without any invasive effect on patients, with low cost and easy to promote on a large scale.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
