Abstract:
The work presents a clinical outline of stature defects and scoliosis as well as the contemporary methodology behind the thorax, spine and leg bone radiogram measurements. In order to increase the repeatability of the results and to create computer records which support monitoring records of scoliosis, an algorithm for the process of radiological image was developed. It automatises the time consuming process of measuring and processing data by the doctor. The image processing is initiated by an interactive procedure where key points of biological structures are marked with a cursor. Other measurements are done automatically. The algorithm is also an attempt to use the author’s modification for measuring the geometry of the spine and thorax, which increases precision when compared to the methods by Cobb, Fergusson and Gruca. Results of radioplan-metric investigations compared with a system for analysing the trajectory of respiratory motion and the asymmetry weight distribution system
in the foot have been presented. A mathematical analysis of thorax and bone radiogram geometry combined with the results of thorax trajectory movement enable the creation of individual patient symmetry indices with a description of the monitoring process of the disease.
