Background

Currently, in CT scanning, the X-ray tube continuously emits X-rays, the human body continuously passes through the aperture of the X-rays, and the X-rays penetrate the human body to form an image. When the cross-sectional area and the density of each part do not change greatly in the longitudinal direction during scanning, the energy of X rays is stable, and the machine can generate clear images. When scanning the lower neck, the human body passes through the aperture of the X-ray from the neck to the shoulder. The neck is thin, the thickness and the width of the human body between two shoulder joints are obviously increased, the total volume is increased by 4-5 times relative to the neck, and the clavicles on the two sides of the shoulder run horizontally and have high density, so that the X-ray is attenuated sharply, and even if the X-ray bulb tube increases the dosage of the emitted X-ray, the influence caused by the attenuation is difficult to compensate. Therefore, significant volume artifacts and beam hardening artifacts appear on CT images of the lower neck, and this effect is particularly severe in the thyroid region, resulting in poor visualization of the thyroid and surrounding structures. In recent years, the incidence of thyroid cancer has been remarkably increased with changes in lifestyle, increased awareness of human health, and popularization of medical screening. Neck CT examination is usually performed prior to surgery to assess the size and nature of the lesion, as well as the course of the surrounding vessels and lymph node metastasis.
