What is high-pressure photography? Which chest lesions are suitable?

High-pressure photography, also known as high-pressure photography, uses high pressure above 1.20kV for chest posture photography. In this state, the X-ray emitted by the bulb tube has strong penetrating power, which can reduce the interference of chest wall soft tissue and ribs on the lungs, and make the images of ribs and chest wall soft tissue fade, thus improving the definition of the images, which is conducive to observing the pathological changes of the lungs and the normal structures such as trachea, bronchus, lung texture and hilum. Clinically, it is often used to check lung mass, atelectasis and lung cavity.
