Premature baby. X-ray of the torso of a premature baby revealing various life support devices. The baby's skull is at top above the spinal column, which runs down to the pelvis at bottom. The bright object at lower right is a sensor for measuring breathing rate. It has been placed over the diaphragm just below the rib cage. On either side of the chest are electrodes connecting to an electrocardiograph (ECG) which monitors the baby's heart. A nasogastric tube is visible passing down the throat into the stomach (at centre right).
