1. Medicine, Nursing and Health Sciences Overview of Radiography and Medical Imaging Course Associate Professor Peter Wells, PhD Adjunct Professor Department of Medical Imaging and Radiation Sciences Associate Professor Marilyn Baird, PhD Head, Department of Medical Imaging and Radiation Sciences Associate Dean, Learning & Teaching, Faculty of Medicine, Nursing and Health Sciences

2. What is Radiography?  A health science profession that actively interacts with the medical profession in the diagnosis and management of human illness through the provision of medical images

3. What do Radiographers do?  Radiographers use a wide variety of imaging modalities to create diagnostic images for analysis and interpretation by a radiologist  Radiographers inform patients about their examination, prepare them for it and position patients for the examination  Radiographers play a pivotal role in selecting and implementing the most appropriate examination protocol to deliver the lowest radiation dose to the patient whilst answering the clinical question

4. Diagnostic Imaging Modalities  Plain Radiography  Fluoroscopy  Digital Vascular Imaging (DVI)  Computed Tomography (CT)  Mammography  Bone Densitometry (DXA)  Orthopantomography (OPG)  Ultrasound (US)  Magnetic Resonance Imaging (MRI)  (Colour key: X-rays, sound waves, radio waves)

11. A ‘Radiologic Department’  A pre-clinical on-campus medical imaging skills laboratory where students practice a defined range of radiographic examinations  Houses a clinical quality x- ray machine and anthro- pomorphic phantoms  Students practice taking x- rays with this phantom

13. Clinical Practice  Students attend hospital radiography departments for extended, full-time periods in each semester  They complete detailed workbooks during each visiting period  Competency based assessments are undertaken during each semester visit  Requires rotation to a variety of clinical departments to cover all modalities

14. Digital Imaging  Finally, this image is reconstructed from a CT scan of the head  The image is surface rendered to provide a realistic 3D image  The underlying structure is still there!
