The Darling River, 1,160 miles (1,879 km) in length, flows southwest from the edges of the Great Dividing Range into the Murray River. The Murray rises in the Australian Alps and flows 1,200 miles (1,930 km) to the Spencer Gulf, directly west of Adelaide.
In lung cancer screening, individuals who have a high risk of developing lung cancer but no signs or symptoms of the disease undergo low-dose computed tomography (LDCT) scanning of the chest.
To produce high-quality scans at a lower radiation dose, low-dose CT scanning uses a variety of techniques, including: 1  dose modulation, in which radiation dosage is continuously adjusted to the patient's size at each location as the patient moves through the scanner.  2 noise management software to filter out unnecessary data.
