Chapter 6 The Chest and Abdomen Chapter 7 The GPT Method Anterior-Posterior (AP) radiographs are taken with the patient facing the -ray tube, so that the x -ray beam enters their anteriorx side, and exits posteriorly. Posterior-Anterior (PA) films are performed while the patient faces away from he t x-ray tube. The -ray beam goes in their posteriorx and comes out their anterior. Lateral
X-ray imaging Curriculum links Electromagnetic spectrum Background radiation Introduction X-ray imaging utilises the ability of high frequency electromagnetic waves to pass through soft parts of the human body largely unimpeded. For medical applications, X-rays are usually generated in vacuum tubes by bombarding a metal target with high-speed electrons and images produced by passing the
The chest X-Ray is a quick procedure, as well as easy, painless and non-invasive, and it allows to obtain images from the different structures within the chest area. With these images’ records, it is possible to look for symptoms of several types of diseases, namely pneumonia, congestive heart failure, lung cancer, pulmonary fibrosis or sarcoid tissue.

A chest X-ray is commonly used to help diagnose and manage chest infections and is widely used in high-income countries. However, the impact of chest X-rays in terms of how they may change patient recovery in suspected chest infection has not been evaluated. We focused on whether the use of chest X-rays compared to not using them led to improved outcomes such as a faster recovery rate, less

Coal workers’ pneumoconiosis . Overview . Coal workers’ pneumoconiosis (or black lung), is an occupational lung disease caused by prolonged exposure to respirable coal dust. If a worker is exposed to high concentrations of coal dust over several years, the dust collects in the alveoli (air sacs) of the lungs causing a reaction that results in scarring of lung tissue, reducing the
