This is the proceedings of an international symposium held to evaluate moiré fringe topography in patients with spinal and other musculoskeletal deformities. It consists of 34 papers presented by 58 persons, both physicians and engineers, from seven countries. There is an excellent index and a very comprehensive bibliography of 254 entries. In addition to the individual research papers, the proceedings of workshops on instrument design and clinical standardization of data are presented. Several panel discussions provide an excellent interchange between the biomedical engineer and the physician, and cover three topics: (1) standardization of techniques, (2) state of the art of screening for scoliosis, and (3) setting goals for future research.
Moiré (meaning "watered silk") topography is a photo-optical measuring technique that does not involve radiation. The patient stands behind a grid of evenly spread lines (nylon or metal). A light projects the grid lines on the patient's back, which can
