Diagnostic Radiology: Physics and Equipment

Semester 1

The aim of this module is to present to the students the basic physical principals of: (a) Conventional planar X-Ray Imaging; (b) Digital X-Ray Imaging and Computed Tomography.

  • Conventional planar X-ray imaging
    • X-ray production.
    • Energizing and controlling the X-ray tube.
    • X-ray tube heating and cooling.
    • X-ray image formation and contrast.
    • Scattered radiation and contrast.
    • Radiographic receptors.
    • The photographic process and film sensitivity.
    • Film contrast characteristics.
    • Radiographic density control.
    • Blur, resolution, and visibility of detail.
    • Radiographic detail.
    • Image noise.
    • Fluoroscopic imaging systems.
  • Digital X-ray imaging and Computed Tomography
    • Digital imaging systems and image processing.
    • Computed tomography image formation.
    • Computed tomography image quality.
    • Mammography.
    • Digital subtraction angiography (DSA).
    • Dual-energy-X-ray absorptiometry (DEXA)
  • Coursework: 50%
    • Two in-course tests (2 x 1 hour) 30%
    • Lab/Practical 20%
  • Final Exam: 50%
    • One 2 hour written paper 50%
Learning Objectives: 

After completing the course, the student should be able to:
• Produce conventional planar imaging topics include radiography and fluoroscopic imaging: production of X-rays, X-ray interaction with the patient
• Produce images using film-screen systems or image intensifiers, and processing of x-ray films.
• Produce images using Digital X-ray imaging and Computed Tomography
• Address image quality issues
• discuss recent advances in hardware and applications: multi-slice detectors, cone beam technology, etc.
• Use axial, helical multi-slice, and cone-beam CT for diagnosis.
