Description

A device for assisting judgment and viewing of lung CT films

technical field

The invention belongs to the technical field of medical equipment, and in particular relates to a device for assisting judgment and viewing of lung CT slices.

Background technique

CT film is a means of diagnosing various diseases by viewing medical images. It uses precisely collimated X-ray beams, γ-rays and ultrasound, etc., together with highly sensitive detectors, to surround a certain part of the human body one by one. Cross-sectional scanning has the characteristics of fast scanning time and clear images. When reading CT films, it is usually viewed directly by holding the CT film against the light source, but there are obviously many problems in viewing inconvenience. The number of CT films viewed first is relatively large. There are few, usually one or two, and additional lights are required, which is time-consuming and labor-intensive, and it is inconvenient to use multiple CT films to compare the condition to the patient, which is not practical. On the other hand, existing CT films are easy to appear during viewing The phenomenon of bending or offset leads to a certain error in the viewing angle, thus affecting the judgment of the disease.
