In digital radiography the sensors shape a plate, but in the EOS system, which is a slot-scanning system, a linear sensor vertically scans the patient. Plain radiography was the only imaging modality available during the first 50 years of radiology.
Swollen ankles and feet. Swollen ankles and swollen feet are common and are often caused by fluid retention, or oedema. The cause of the swelling can range from an injury to medical conditions. Seek medical advice if you are concerned about swollen feet or ankles.
Injury to the Feet and Ankles. Another cause of foot and ankle swelling is injury or trauma to the feet. When the tissues and muscles of the feet and ankles are strained or damaged, they will become inflamed and fill with blood, causing swelling.
