Electrostatic X ray photograph sensitive plate and film cassette

Abstract

The invention discloses an electrostatic X-ray photographic sensitive plate, comprising a conductive plate, the surface of the conductive plate is covered with a light sensitive film, side strips which are fixedly connected with the conductive plate are respectively arranged on the corresponding sides of the both sides of the conductive plate, at least one position corresponding penetration slot is arranged on each side strip, and the interior of the penetration slot is embedded with a bearing with a U-shaped slot or a V-shaped slot. The invention further discloses a cassette of the electrostatic X-ray photographic sensitive plate, comprising a box body, the box body is composed of a bottom surface, a top surface, a left side surface, a right side surface, a back side surface and a cassette door which is positioned at the front end of the box body, the position on the bottom surface in the box body which is near to the left side surface is provided with a first guide track which is corresponding to the shape of the U-shaped slot or the V-shaped slot of the bearing with the U-shaped slot or the V-shaped slot, and the position on the bottom surface in the box body which is near to the right side surface is provided with a second guide track which is corresponding to the shape of the U-shaped slot or the V-shaped slot of the bearing with the U-shaped slot or the V-shaped slot.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an electrostatic X-ray photographic photosensitive plate and a cassette. Background technique [0002] In 1937, American scientist Carison invented electrostatic X-ray photography. At present, the most widely used is selenium electrostatic X-ray photography (Xeroradio-graphy). The working principle of selenium electrostatic X-ray photography is: [0003] (1) Cover the amorphous selenium photosensitive film on the conductive plate, such as figure 1 As shown, an amorphous selenium photosensitive flat plate (referred to as a selenium plate) is made, and then the selenium plate is placed in an electrostatic field, and is charged with a uniform electrostatic charge under dark conditions. [0004] (2) Put the selenium plate with uniform electrostatic charge into the cassette under dark conditions. [0005] (3) Put the cassette under the X-ray tube, put the photographic obje...

AI Technical Summary

Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a photosensitive plate and a cassette for electrostatic X-ray photography, which overcomes the conventional electrostatic X-ray photographic photosensitive plate cassette. The defect that the image quality fluctuates due to the position difference, and the defect that the selenium plate enters and exits the cassette because there is no track guidance, and the defect is relatively large
