Full text available as: Abstract/SummaryThis report concerns with the collection and processing of data acquired from three-dimensional (3D) surface scans of scoliosis patients' backs. Two main issues were addressed: the reproducibility of the results, and stringent time constraints. In particular, user influence should be removed from each step of the data processing, and results should be obtained within three minutes of acquiring the scan.
The report begins with a description of the data collection, followed by a description of the data processing required to align two back surfaces. A section is devoted to calculating the cosmetic score, a measure of deformity of the back. The paper concludes with a few suggestions for improvements on data collection and use. | Item Type: | Study Group Report |

Problem StatementScoliosis is a fairly common condition that usually appears during adolescence. It involves mild to severe deformations of the spine. Doctors and patients are interested in measuring the progression of the disease. Internal changes in spine angles and twists can be seen from X-rays, but surface (appearance) changes are often of primary concern to adolescent patients.
Measuring the amount of surface change can be a difficult problem. Natural growth, changing body shape, and progression of the disease all factor into forming the shape of the patient's torso. Separating these effects, and extracting the change due to scoliosis alone, is challenging. In an effort to
quantify the changes due to scoliosis, Capital Health acquires three-dimensional (3D) surface scans of a subject's back every 3 to 6 months using a laser scanner. The problem we wish to address in this workshop is how best to use this data to obtain useful measures for both the doctor and patient. Archive Staff Only: edit this record
