The development of a new method of cephalometric and study cast mensuration with a computer controlled, video image capture system: Part I.

A computerized system for handling cephalometric images, developed at the Royal Berkshire Hospital in Reading, was tested against a conventional manual tracing method and a computer-controlled digitizer. Systematic errors, calibration, and handling aspects are discussed. Results showed that the computerized system provided data which compared favourably with the same measurements carried out conventionally using manual or digitizing methods.
