Low-density resolution ratio detector for X-ray radiography machine of dental department

Abstract

The invention provides a low-density resolution ratio detector for an X-ray radiography machine of the dental department. The low-density resolution ratio detector is characterized by being composed of a bottom die (1), a left inserting block (2) and a right inserting block (3). The bottom die (1) is provided with an inserting groove (4) matched with an arrangement curve of standard human teeth. The inserting groove (4) is composed of a left straight line section, a right straight line section and an arc section connecting the left straight line section and the right straight line section. The left inserting block (2) is inserted into the left straight line section of the inserting groove (4), and the right inserting block (3) is inserted into the right straight line section of the inserting groove. The left inserting block (2) and the right inserting block (3) are respectively provided with a groove in the length direction, wherein the depths of the grooves are of equal difference distribution. The low-density resolution ratio detector is simple in structure, convenient to manufacture and use, and capable of achieving ration judgment of the resolution ratio.

Description

technical field [0001] The invention relates to a detection tool, in particular to a resolution detection tool for medical X-ray equipment, in particular to a low-density resolution detection device for a dental X-ray camera. Background technique [0002] At present, dental X-ray cameras have been widely used clinically, providing great help for the diagnosis and treatment of dental diseases. Since the X-ray camera is a kind of special equipment, it needs to be inspected regularly, especially the resolution is an important indicator, it will continue to decline with the extension of the working time of the equipment, and the relevant parameters must be adjusted in time to improve the resolution , but due to the lack of corresponding detection tools and the inability to directly use the patient's teeth for detection, it is difficult to carry out quantitative detection of resolution, and the resolution control is completely based on the operator's feeling, which affects the ...
