RAD2911 — Image Quality and Acquisition I
1 Credits This course explores the use of physical grids and grid application software, focusing on technical factors and their impact. Key topics include the principles and operation of image intensification tubes, and how radiation dosage affects patients, radiographers, and radiologists during fluoroscopy examinations. The course also introduces digital radiography, covering histogram acquisition and the factors influencing digital image quality. Analyze the impact of physical grid selection on patient dose and image receptor exposure. (PLO 11) 2. Critically evaluate radiographic images to identify and diagnose errors associated with the use of physical grids. (PLO 7) 3. Assess the effectiveness of grid replacement software in optimizing image quality and patient safety. (PLO 11) 4. Synthesize the principles of image intensification by examining the interrelated functions of the input screen, photocathode, electrostatic focusing lenses, anode, and output screen. (PLO 11) 5. Critique the factors influencing fluoroscopic image contrast, resolution, distortion, and quantum mottle, proposing strategies to optimize image quality. (PLO 6, 7) 6. Formulate advanced methods for minimizing dose to the patient, radiographer, and radiologist during fluoroscopic examinations. (PLO 5) 7. Evaluate the process of digital image data formation, identifying critical factors that affect data integrity and accuracy. (PLO 11) 8. Analyze the process of histogram acquisition and determine how the
