British Journal of Orthodontics, 1984
Sources of cephalometric error are considered, and different techniques of measurement are discussed. The use of the digitizer on tracings, untraced films and modified tracings is evaluated with regard to reproducibility of cephalometric angles and co-ordinates.

An overview of computerized cephalometrics
American Journal of Orthodontics, 1972It is realized that clinicians, students, and the scientific community are herein asked to accept a great deal in the selection of points and the values of different parameters. However, after several years of manual methods, work with the computer has produced an outpouring of new knowledge.

An Introduction to Centroid Cephalometrics
British Journal of Orthodontics, 1982Traditional cephalometry has depended upon measuring the relationship of anatomical points and lines (or planes) to each other. A centroid approach defines two relatively stable lines, each of which can be used for reference purposes and for analysing craniofacial changes elsewhere.

Cephalometric studies of the skull
Plastic and Reconstructive Surgery, 1961Summary The role of cephalometric X-ray methods in the study of facial growth and morphology is investigated. Examples of the practical use of such X-rays and measurements from them are given as they may be applied to the treatment of facial disharmonies of mandibular origin.

Clinical Orthodontics and Research, 2000
Identification of craniofacial landmarks, particularly condylar anatomy, on the lateral cephalometric radiograph is erratic. The accuracy of recognition is critical for proper diagnosis of malocclusion and for assessing growth and orthodontic treatment.

Reproducibility of Cephalometric Measurements
British Journal of Orthodontics, 1988This cephalometric study was undertaken to compare and contrast the errors involved in taking linear and angular measurements using three different methods; hand instruments on tracing, digitization of tracings, and direct digitization of the radiographs.

A method of cephalometric evaluation
American Journal of Orthodontics, 1984This paper describes a method of cephalometric analysis which is currently used by the author in the evaluation and treatment planning of orthodontic and orthognathic surgery patients. In the analysis of a single film, the positions of the maxilla and mandible are related to cranial structures and to each other.

A cephalometric appraisal of xeroradiography
American Journal of Orthodontics, 1980The literature on the physics, the radiation hazard, and the current medicodental applications of xeroradiography is reviewed. A study is presented on estimating the effect of a xeroradiographic technique on the degree of inter- and intraobserver error in cephalometric landmark identification, as compared to a radiographic technique.

Cephalometric Analysis for the Surgeon
Clinics in Plastic Surgery, 1989A protocol for cephalometric analysis is presented to enable the clinician to evaluate the craniofacial skeleton for surgery. Cephalometric tracing and analysis are described and applied to a clinical case. The three-dimensional cephalometric method and analysis are discussed for application in planning the correction of craniofacial asymmetry.

Computers in cephalometric research
Computers in Biology and Medicine, 1970Abstract With the introduction of computers a marked acceleration in cephalometric research occurred. A survey of this development is given. The computers were first used to facilitate statistical calculations. Then the entire measurement technique was changed.
