Embodiment Construction

[0029] A medical digital computer image imaging method mainly includes the following steps: a. making an amorphous selenium photosensitive film on a flat plate such as metal or conductive glass, and then placing the flat plate in an electrostatic field, and using high voltage The principle of electrostatic corona discharge allows it to be charged with a uniform static charge; b. Put the electrostatically charged photosensitive plate into the cassette under dark conditions; c. Place the cassette under the X-ray tube and put the subject on it ; d, X-ray exposure is carried out to the cassette with the object to be photographed; e, the static charge on the photosensitive flat plate through X-ray exposure changes, the static charge of the fully exposed part disappears, the static charge of the unexposed part is fully retained, and the partial exposure Part of the electrostatic charge left and part disappears, and at this time, a very complete "latent image" of the electrostatic pot...

Abstract

An imaging method for the medical digital or computer image includes such steps as putting an object to be imaged in a dark box, putting an electrically conductive charged metal or glass plate in said dark box, X-ray irradiating to form a latent image on said charged metal or glass plate, spraying the developing powder onto it to show a clear image, A / D conversion by digital camera or scanner, and inputting the clear image to computer.

Description

technical field [0001] The present invention relates to the technical field of medical digital imaging, in particular to yet another medical electrostatic imaging technology. Background technique [0002] At present, the relatively advanced electrostatic imaging technology used in hospital clinical diagnosis is DR (Digital Radiography), that is, digital image imaging technology. The imaging steps are: 1. Make amorphous selenium photosensitive film or amorphous silicon photosensitive film The matrix conductive glass plate, that is, the TFT sensor, is placed in an electrostatic field to allow it to be charged with a uniform electrostatic charge. (Because it is a fixed cassette, all additional devices are in it and cannot be moved, special plane, special film, dedicated); 2. Put the subject on the fixed cassette position and perform X-ray exposure; 3. After X-ray exposure, On the amorphous selenium photosensitive film, a complete but invisible electrostatic potential "latent i...
