Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field especially, relate to a kind of wearing equipment of QCT phantom. BACKGROUND

[0002] Generally speaking, quantitative CT (QCT) is a kind of image technology based on ordinary or spiral CT, which measures the bone density of lumbar vertebra. The basic principle is that the object to be measured and the calibration phantom with known equivalent bone density are scanned by CT at the same time, and then the CT values of the measured area and the calibration phantom are analyzed by QCT software respectively. The actual bone density of the measured area is calculated by taking the equivalent density of the calibration phantom as a reference.

[0003] For the selection and placement of the phantom, an equivalent reference phantom containing hydroxyapatite is usually selected. The phantom has the same radiological characteristics as bone mineral, which can ensure the accuracy of the measurement. The standard phantom is placed under the lumbar vertebra of the subject and as close as possible to ensure that the phantom and the subject move synchronously during scanning, reducing errors.

[0004] The existing phantom wearing equipment on the market generally adopts a fixed mode, that is, the phantom is firmly installed in the wearing equipment, and then the operator tightly binds the entire wearing device around the patient's waist area. However, during long-term frequent use, the material of the phantom often faces the challenges of aging, deformation, or density fluctuation, which negatively affects the accuracy of calibration. For example, materials such as plastic or polymer may gradually lose their original physical stability and degrade after being subjected to CT scanning radiation for a long time. Phantoms containing liquids, such as water phantoms, may change in density due to evaporation or leakage. Once the phantom shows signs of aging, it must be replaced. Unfortunately, the existing wearing equipment does not have the function of replacing the phantom, and it cannot flexibly select the corresponding size of the phantom according to the different body types of patients.

[0125] In some embodiments, the second anti-skid member includes but is not limited to a non-slip pattern pad.

[0126] The use method and advantages of the embodiment are the same as those of the embodiment 1, and will not be described here.

[0127] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0128] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
