Radiographic imaging and methods 1

Objectives On successful completion of this subject, students will know how to conduct and evaluate radiographic examinations of the upper and lower limb. The imaging component of this subject provides students with an understanding of the x-ray machine and console and film-screen radiography; the causes of scattered radiation and its control; the fundamental principles of radiographic film and intensifying screens, photochemistry, processing the latent radiographic image and sensitometry. The methods component of this subject will provide students with a sound understanding of the principles underpinning radiographic positioning and the use of radiographic equipment.

Synopsis The x-ray system, x-ray generators (fixed) and the x-ray console. Causes of scattered radiation and methods for its control. Characteristics of image receptors, fluorescent intensifying screens, screen categories, light diffusion, cassettes. Film materials and the fundamentals of the science of sensitometry. Photochemistry and automatic processing. Radiographic projections for the upper and lower limb and chest. Laboratory teaching sessions will enable students to develop pre-clinical radiographic skills in these examinations, to a basic level of technical competency.

Assessment Examination (3 hours): 60% * Laboratory reports: 30% * Viva voce: 10%
