PART 3.1 - RADIOGRAPHIC TECHNIQUE
Overview
What's in part three?
Overview of Part 3 - Radiographic Technique
Within Part 3 - Radiographic Technique you will learn how the manner in which we perform radiography may alter the quality of the image. More specifically, this section will cover the key concept of geometric unsharpness. We will look at image distortion due to the position of the X-ray tube, specimen and image receptor. Lastly, Part 3 shall outline radiogrammetry as an alternative method for indicating bone loss due to age, osteoporosis, or other pathologies.

There are reading tasks throughout which will help to illustrate these concepts. A list of all reading tasks can be found in the Learning Resources section.
We've covered some very important radiographic concepts so far:
Radiographs present three-dimensional objects as two-dimensional images
The amount of 'whiteness' upon an image correlates with its density
The next key concept concerns the potential for image distortion upon a radiograph depending on how the investigator performs the imaging.
This is the final 'practical' concept that I shall be introducing before we explore how paleoradiography may be used as a research tool within Part 4.
