Description

PET-CT head support with physical positioning function

Technical Field

The utility model relates to a scanning head support, in particular to a PET-CT head support with a physical positioning function.

Background

In medical imaging systems, such as PET/CT, PET/MR, and whole-body 2 m dynamic PET/CT, multiple time-phase image contrast is required to achieve more accurate image diagnosis. However, due to the fact that a patient needs to go up and down the examination table for multiple times of imaging, the body position of the patient is slightly displaced during scanning, accurate registration of the physical position of multi-time phase image contrast cannot be achieved, in order to guarantee the quality of the multi-time phase image contrast of PET and achieve the optimal diagnosis and treatment effect of treatment evaluation, an operator is often required to perform basic physical body position fixing on the patient who is examined for multiple times, but the basic physical body position fixing is limited by the operation technical capacity of the operator, the manual judgment and operation positioning process is not accurate, the accuracy of the multi-time phase contrast can be affected, the defect is particularly prominent in the examination of whole-body PET/CT, the defect affects the quality of the image contrast evaluation, and the diagnosis efficiency and the diagnosis accuracy can be affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a PET-CT head support with a physical positioning function, which can quickly and conveniently realize the unified positioning of the physical position of the head of a patient through a simple structure, and has convenient operation and more accurate positioning.

The technical purpose of the utility model is realized by the following technical scheme:

a PET-CT head support with a physical positioning function comprises a head support body and a baffle which is arranged at the inner side of the head support body in a clamping and embedding manner for positioning, wherein a plurality of stages of stepped slots for clamping and embedding adjustment of the baffle are circumferentially arranged on the inner side wall of the head support body close to the top at intervals along the length direction; the inside wall of head rest body is provided with the scale who carries out the measurement record along length direction level.

Adopt above-mentioned scheme, the top inside wall inlay card baffle at the head support body, can the butt fix a position at inspection patient's top of the head, the multistage step slot that the inside wall of head support body top was seted up, make the baffle adjust the location according to the patient of different physiology length structure heads and neck, the scale of inside wall setting, can cooperate in the baffle, carry out the accurate measurement record of head initial position when patient's head is arranged in the head support body on, when needing patient to carry out many times up and down the inspection bed and scan the inspection, can make at every turn scan head position unified, position accuracy is unified during the multi-time scanning, the accuracy matches, avoid the deviation of physical displacement to each time phase image aspect.

Preferably, the head support body comprises a connecting plate with an upward arc-shaped opening and an inserting plate which is positioned at the bottom and is integrally connected with the connecting plate; arc-shaped grooves for positioning and placing the ear parts are formed in the edges of the two sides of the connecting plate; one side of the baffle close to the head support body is in arc-shaped arrangement in the step slots in an abutting and clamping manner.

By adopting the scheme, the two sides of the head support body are bent into arc shapes, so that the head support conforms to the head of a person, the position of the head can be limited around the head, and the arc-shaped grooves arranged on the side walls can facilitate the placement of the ears of a patient to be examined, so that the patient can be preliminarily positioned while the patient is comfortable to use; baffle one side edge is that the setting of arcuation can be better carries out the inlay card butt with the step slot of head support body, and then makes placing of baffle more stable.

Preferably, the baffle is made of carbon fiber, and a plurality of through holes are formed in the surface of the baffle.

In conclusion, the utility model has the following beneficial effects:

the baffle is embedded at the top of the head support body, so that the head support can be positioned at the top of the head of a patient through the baffle when the patient is examined, the positioning position can be conveniently adjusted according to patients with different physiological structures due to the arrangement of the multi-stage step-by-step slots, and the graduated scale arranged on the inner side wall of the head support body can be matched with the baffle plate to measure and record the head initial position of the patient, further accurately recording the initial position of the head of the patient, and when the patient is examined on and off the examination bed for a plurality of times, the head position of the patient can be conveniently and accurately adjusted each time, multi-temporal scanning and accurate and uniform position are achieved in the whole-body PET scanning examination, can achieve accurate matching when comparing images, avoids the deviation of physical displacement to each time phase image layer, the accuracy of medical images, particularly multi-time point PET images in the evaluation and comparison of the treatment efficacy is well guaranteed.

Drawings

Fig. 1 is a schematic structural view of the head rest of the present invention.

In the figure: 1. a head rest body; 2. step-by-step slot; 3. a baffle plate; 4. a graduated scale; 5. an arc-shaped groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

According to one or more embodiments, a PET-CT head support with physical positioning function is disclosed, as shown in fig. 1, comprising a head support body 1 and a baffle 3 capable of being mounted on the inner side wall of the head support body 1 in a snap-fit manner.

Head is placed to head support body 1 confession patient, and head support body 1 is including connecting plate and picture peg, and the connecting plate upwards is the setting of arcuation for the crooked opening in both sides, and the bending degree is close with the human brain outline for carry out preliminary spacing in the patient head outside, picture peg integral connection in connecting plate is located human neck below during the use. Arc wall 5 has been seted up at the both sides edge of connecting plate to head support body 1, is close with the position of people's ear for supply ear's inlay card, when patient's head was located head support body 1, roughly inject head position, the preliminary ear position of injecing of arc wall 5 through head support body 1, about going on and preliminary location from top to bottom.
