EOS differs in several other respects from traditional film, digital Xray or CT. Its use of slot scanning technology eliminates vertical distortion that is common with traditional Xray systems. In addition, EOS enables long length digital imaging without the need for digital stitching -- all at a reduced dose. The simultaneous bi-plane image acquisition (front and side images acquired at the same time) eliminates the need for taking a second view and can save time.
According to a 2007 American College of Radiology study the benefits of diagnostic imaging are immense(1) however, information gleaned from the International Commission on Radiological Protection has reported that CT doses can indeed approach or exceed levels that have been shown to result in an increase in cancer.(2)
In addition, a June 19, 2007, New York Times article reported that the U.S. per capita radiation dose from clinical imaging exams rose by 600 percent between 1980 and 2006, with a major contributor being CT exams, whose numbers have increased over 20 times during this period.
The low dose benefits of EOS may be particularly useful for patients with spinal disorders, such as scoliosis, a spinal deformity condition affecting over 900,000 people in the U.S. alone. Scoliosis patients are typically required to undergo numerous radiographic exams to monitor progression of the disease as well as treatment effectiveness. A retrospective study of over 5,500 female scoliosis patients who received an average of 25 radiographs and whose initial diagnoses spanned a period of 50 years concluded that a statistically significant 70 percent excess risk of dying of breast cancer was observed compared to the general population.(3)
