The inappropriateness of conventional cephalometrics [PDF]
American Journal of Orthodontics, 1979 1. Cephalometric conventions today may have little basis in either biology or biometrics. 2. There is no theory of cephalometrics, only conventions which involve landmarks and straight lines only. These fail to capture the curving of form and its changes, exclude proper measures of size for bent structures, and misrepresent growth, portraying it as ...

On the cephalometrics of skeletal change [PDF]
American Journal of Orthodontics, 1982 This essay introduces the general tensor analysis of skeletal change for landmark data. Consider first a single triangle of landmarks at two times. Joint changes in the lengths of its sides, or in the positions of its vertices according to some coordinate system, may be taken to specify a uniform deformation of the entire interior.

Acta Odontologica Scandinavica, 1978
A method to analyse cephalometric radiographs with the help of a computer has been described. With the system a cephalometric radiograph can be analysed and the results compared to corresponding analyses of individuals with ideal occlusion. The results can also be visualized as schematic figures of the patients.

A sample of 104 patients, males and females between the ages of 6 and 16 years, was studied. The sample included patients with clinically diagnosed nasopharyngeal obstruction, patients with no obstruction, and random sample of patients for whom the presence or absence of obstruction was not known.

Linearity of cephalometric digitizers
The European Journal of Orthodontics, 1991The present study aimed to develop a test procedure to diagnose and visualize errors in linearity of digitizing tablets. Errors of linearity are caused by the distortion of the x- and y-co-ordinates of the digitizing tablet. This results in a given object apparently having different dimensions when recorded on different locations of the digitizing ...
