Torso deformity is often the primary complaint of a patient with scoliosis. Non-invasive detection of progression of the underlying scoliosis from torso deformity would reduce the cancer risk associated with spinal X-rays (Levy et al., 1996) and may define the 3-D scoliosis deformity more completely and with greater sensitivity to patient concerns than simply measuring the Cobb angle on a plain...

Scoliosis is a musculoskeletal disorder manifested as a three-dimensional spinal deformity. It affects 2% 3% of the adolescent population. The conventional method to diagnose scoliosis is to measure the Cobb angle from posteroanterior radiograph. Since radiation exposure is not desirable for patients, other non-ionizing methods have been explored. Among all the non-ionization methods, ultrasoun...
