Features

  • up to date assessment of current image processing techniques
  • clear, concise exposition from physics basics to how to use the different tools available to get the best image
  • examples by chapter relevant to radiography
  • written for the need for engineers to understand the process from image formation to interpretation: unique
  • previous information only available in research and conference papers such as SPIE
  • topical, as increase in computer power has led to massive improvements in image enhancement and interpretation
  • sub via CAMPEP and RSNA accredited programs throughout the USA, and via IFMBE / U Amsterdam contacts in Europe.

    • Summary

    Suitable for students with a first degree in physics, electrical engineerin, computer science or biomedical engineering. The original aim of this book was to provide dentists with an accessible text that explained how to use computer power to reconstruct and enhance radiological images, for diagnosis and for planning appropriate treatment for maxillo-facial disorders. Dentists spent money on new equipment, and have been more open to exploring new techniques than their colleagues working in radiology and radiotherapy departments. No longer. This book will provide a unique text for students in biomedical engineering, and medical physics faculty studying image processing / analysis / computer tomography. Enhanced computing power is now widely used in radiology and radiotherapy departments for improved diagnosis, and treatment planning. It enables earlier detection (for example) of tumours. Its more detailed pictures enable more accurate analysis of soft tissue damage (for example) in sport injuries, or more appropriate dosimetry in radiotherapy.
