X-ray breathing gating mechanism

Abstract

The invention provides an X-ray breathing gating mechanism. The X-ray breathing gating mechanism comprises a first bed board, wherein a sliding area is arranged in the middle of the first bed board, and a second bed board is arranged on the sliding area in a sliding mode; a sliding adjusting mechanism is arranged on the side edge of the first bed board and used for adjusting the sliding position of the second bed board; and a breathing detection mechanism is arranged in the middle of the second bed board. According to the X-ray breathing gating mechanism, 1, the breathing detection mechanism is arranged, fluctuation of the abdomen of a photographer is detected through a pressure sensor, shooting is controlled to be started, accuracy is high, and shooting quality is good; and 2, an abdomen binding belt is adopted in the breathing detection mechanism and is in a tensioned state all the time, the abdomen binding belt plays a role in fixing and limiting the photographer, the pressure sensor is tightly attached to the abdomen of the photographer all the time, detection accuracy is guaranteed, and the X-ray breathing gating mechanism is more suitable for children and special photographers with unclear consciousness under the cooperation of a foot fixing mechanism and a wrist binding mechanism.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for medical image diagnosis, in particular to an X-ray breathing gating mechanism. Background technique [0002] Chest X-ray photography is a commonly used clinical method for diagnosing chest diseases. During the examination process, the patient's breathing coordination is very important, and it is required to take a deep breath before exposure in clinical practice. The main reasons are: 1. After inhalation, the lungs expand more fully, which is conducive to the detection of lesions; 2. After the air enters the chest cavity, the average density of the tissue in the region of interest decreases, and the required radiation dose is smaller. Studies have shown that the radiation dose released by the device can be reduced by an average of 30% when the inhalation phase exposure is compared with the exhalation phase exposure. Clinically, radiologic technologists generally instruct patients ...

AI Technical Summary

Problems solved by technology

However, before the exposure, whether the patient took a deep breath according to the doctor's instructions, the technician cannot accurately know

Some patients have hearing impairment, or infants, elderly patients and comatose patients cannot cooperate with instructions at all

If the effect is not good after exposure, you can only repeat the photography

This brings unnecessary radiation to patients and a waste of medical resources
