Background

Chest radiography is a common method for diagnosing chest diseases clinically, the breathing coordination of patients is very important in the examination process, and deep inspiration is required for exposure clinically. Mainly because: 1. the lung is expanded more fully after inspiration, which is beneficial to the detection of focus; 2: after air enters the chest cavity, the average density of the tissue of the region of interest is reduced and the required radiation dose is smaller. Studies have shown that the radiation dose delivered by the device can be reduced by 30% on average with an inspiratory phase exposure compared to an expiratory phase exposure. Clinically radiologists typically prescribe patients to inhale deeply through a breath-hold by a microphone in the operating room before exposure. However, the technician cannot accurately know whether the patient has performed deep inhalation according to the doctor's instruction before the exposure. Some patients have hearing impairment, or infants, elderly patients and comatose patients cannot cooperate with instructions at all.
