Radiographic methods 4 and digital image processing 1

Objectives On completion of this subject students will have a detailed knowledge of the contrast examinations of the urinary and hepato-biliary systems utilising fluoroscopy and non-fluoroscopic imaging. Students will have a sound knowledge of paediatric radiographic examinations and the necessary conceptual understanding of digital image processing and its applications in medical imaging. The student will have a thorough knowledge of image representation, image acquisition, image transformation, basic image processing hardware and the transmission of images in a medical environment. In this way students will be able to apply a scientific perspective to digital radiography.

Synopsis Paediatric radiography, contrast examinations of the urinary and hepato-biliary system. The image processing component will cover: image acquisition, sampling and quantisation. Digital image representation. Image storage devices. Pixel grey levels, look up tables, the grey scale histogram and point operations. Convolutions and spatial filtering. Introduction to image processing hardware and software. The facilitation of image processing by Picture Archival and Communication systems, and the operational principles of digital radiography systems.
