Digital X-Ray

Digital X-Ray is a modern imaging technology that uses digital sensors instead of traditional photographic film to capture images of the inside of the body. Like conventional X-rays, it relies on electromagnetic radiation to create images of bones, tissues, and organs. However, digital X-rays offer several advantages over traditional methods, including faster results, higher image quality, and less radiation exposure.

Although pulmonary medicine only began to evolve as a medical specialty in the 1950s, William Welch and William Osler founded the ‘parent’ organization of the American Thoracic Society

One of the first major discoveries relevant to the field of pulmonology was the discovery of pulmonary circulation. Originally, it was thought that blood reaching the right side of the heart passed through small ‘pores’ in the septum into the left side to be oxygenated, as theorized by Galen; however, the discovery of pulmonary circulation disproves this theory, which had previously been accepted since the 2nd century. Thirteenth century anatomist and physiologist Ibn Al-Nafis accurately theorized that there was no ‘direct’ passage between the two sides.
