Description

X-ray medical image film automatic imaging system

Technical Field

The invention relates to the technical field of medical image imaging, in particular to an automatic imaging system of an X-ray medical image film.

Background

Medical imaging refers to the technique and process of obtaining images of internal tissues of a human body or a part of the human body in a non-invasive manner for medical treatment or medical research. It contains the following two relatively independent directions of study: medical imaging systems and medical image processing. The former refers to the process of image formation, including the research on the problems of imaging mechanism, imaging equipment, imaging system analysis and the like; the latter refers to further processing of the acquired images, either to restore the original less sharp image, to highlight certain feature information in the image, or to perform pattern classification on the image.

X-ray film is photographic film designed for X-ray photography. The film is roughly classified into two types, direct photography (intensifying screen type and non-intensifying screen type) and indirect photography. The X-ray films are mainly medical X-ray films and industrial X-ray films according to the purposes. Medical X-ray films use a light blue film base to prevent halo formation. When the device is used, a fluorescence intensifying screen can be added to excite fluorescence for shooting, and the effect is better. Industrial X-ray films require fine particles, low haze, high contrast, high density and high resolution. In addition, radiation-sensitive films for determining the radiation dose are also known, and films for radiographic reproduction are also included in the broad sense.
