Enlargement and Distortion in Cephalometric Radiography: Compensation Tables for Linear Measurements.
An evaluation of image distortion and serial variation in oblique cephalometric radiography. Reduction of inaccuracies from these sources is best achieved by aligning images of the inferior border o...
The advent of rare-earth screen/film combinations has brought substantial x-ray dose reductions with minimal loss in imaging quality. The physical charateristics of these recording systems are des...
An experimental quantification of changes in position of cephalometric images caused by variation in head rotation in successive radiographs.
Digital imaging has several potential advantages over traditional cephalometry. These include storage, transmission, and enhancement of images, reduced exposure to radiation for patients, and the poss...
Patient radiation exposure was determined for conventional and direct-digital cephalometric radiography. An anthropomorphic phantom was positioned to expose lateral cephalographs from the patient'...
Objective: To evaluate the reliability of landmark identification in posteroanterior cephalometrics.Materials and Methods: A literature search was conducted to identify all articles concerning landmar...
