Production method of water phantom

Abstract

The invention discloses a production method of a water phantom. The production method includes the steps of feeding, wherein a certain margin is given according to the part size requirements in a water phantom drawing, and a part blank is cut on a made material; baking, wherein the part blank is baked; part machining, wherein the baked part blank is cut according to the requirements of the drawing, and a machined formed part is obtained; cleaning, wherein the machined formed part is cleaned; pasting of a protective layer, wherein the protective layer is pasted on the portion, needing pasting of the protective layer, of the cleaned part; glue injecting, wherein the portion, needing pasting is subjected to glue injecting, and a water phantom is formed; baking, wherein the glue-injected formed water phantom is baked; edge trimming, wherein the baked water phantom is trimmed, and the size in the water phantom drawing is reached; cleaning. According to the production method of the water phantom, the production quality is guaranteed through a complete and standard production process, the production quality is very stable, and the percent of pass of products is high.

Description

technical field [0001] The invention relates to the technical field of water molds, in particular to a production method of water molds. Background technique [0002] The CT machine water phantom is a key component in X-ray computed tomography as a CT machine performance test, accurate diagnosis of disease, and calibration index. Its production quality is completely guaranteed by the production process. [0003] Using different process methods and process routes, the quality and yield of this type of phantom will be different, because without process guarantee, no qualified products can be produced. [0004] In the existing similar technology, for example, the Chinese patent with the application number of 201320838594.4 discloses a water phantom for CT quality control testing, and the quality control of this type of phantom has been discussed, and its purpose is to improve the existing Catphan500 phantom. Directly built-in water phantom, the method is to express how the fu...

Problems solved by technology

[0004] In the existing similar technology, for example, the Chinese patent with the application number of 201320838594.4 discloses a water phantom for CT quality control testing, and the quality control of this type of phantom has been discussed, and its purpose is to improve the existing Catphan500 phantom. Directly built-in water phantom, the method is to express how the function and performance of the existing phantom are realized in structure, which involves some quality problems of this type of phantom, but the production process has not been introduced in detail, and it is difficult to guarantee the production quality Stablize

[0005] As far as general production is concerned, if only the structure of the mold body is given, including the mutual position and dimensional relationship between the parts, it may not be possible to produce a mold body that meets the quality standards. Even if it can be produced, it is accompanied by product quality. It cannot be guaranteed, resulting in a decline in yield, increased production costs, and seriously affects delivery time, reducing credit to customers
