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.
Swollen ankles occur when fluid is retained in the spaces between our cells. This fluid buildup can have a number of different causes, most notably insufficiency of the venus system, water retention secondary to heart, kidney, liver, or endocrine disease, as well as local musculoskeletal issues such as trauma, infections, or tumors. All of these can cause swollen ankles. Pregnant women deal with swollen ankles on a daily basis due to weight gain and water retention. Waiters and waitresses also deal with swollen ankles after standing and walking for long periods.
