Head support for PET-CT examination in nuclear medicine department

Abstract

The invention provides a head support for PET-CT examination in the nuclear medicine department. The head support comprises a bottom plate and a top plate; an included angle is formed between the top plate and the bottom plate; and when the back side of the head is placed in a concave formed in a cushion layer of the upper surface of the top plate, the lowest point of the head coincides with the center point of the concave, and the included angle between the eyebrow listening line of the head and the bottom plate is basically 90 degrees. The head support further comprises a head high point height detection module used for detecting the highest point of the head, a head low point height detection module used for detecting the lowest point of the head, a top plate lifting system and a microprocessor, the microprocessor is used for calculating the middle height value of the height of the highest point and the height of the lowest point, and a top plate lifting system is controlled according to the difference value between the middle height value and the optimal scanning height, so that the top plate is lifted to the optimal height. On the premise of ensuring that an eyebrow listening line serves as a scanning base line, the brain of a patient is located in the center area of the brain scanning range of the equipment in the vertical direction through automatic lifting of the top plate.

Description

technical field [0001] The invention relates to the field of radiological diagnostic equipment, in particular to a headrest for PET-CT examination in nuclear medicine. Background technique [0002] The perfect combination of PET and CT, PET-CT can not only provide detailed molecular information such as function and metabolism of lesions, but also provide precise anatomical location of lesions at the same time, with the advantages of sensitivity, accuracy, specificity and precise positioning, so as to achieve early detection of lesions and to diagnose diseases. Clinically, it is mainly used in the early detection and diagnosis of major diseases in the fields of tumor, brain and heart. [0003] In the PET-CT diagnosis of the brain, the brow line (the brow line (EML) is the line connecting the midpoint of the upper edge of the human eyebrow and the external ear hole) is usually used as the scanning baseline, and the brow line needs to be basically perpendicular to the scanning...

AI Technical Summary

Problems solved by technology

In practical applications, the best brain scanning range of scanning equipment is certain, but for the heads of different people, due to their different sizes, especially the difference between the head sizes of children and adults is more significant, even if the head size is guaranteed In the diagnostic scanning process, the listening eyebrow line is used as the scanning baseline, and it is difficult to ensure that the central area of ​​the equipment's optimal brain scanning range matches the brain as much as possible, especially in the vertical direction due to the different head sizes. Therefore, the existing scanning method that uses the auditory brow line as the scanning baseline cannot guarantee that the brain scans of all patients are in the central area of ​​the optimal brain scanning range, and cannot guarantee to provide Clearest brain structure
