PART 3.5 - RADIOGRAPHIC TECHNIQUE
Summary and quiz
Within paleoradiography there are a wide range of variables to take into account. Aside from the different settings of the X-ray tube there are also considerations for the position and alignment of the X-ray tube with the specimen and image detector.
The application of accurate and appropriate radiographic technique is essential for worthwhile, valuable imaging. Incorrect radiographic technique may lead to distorted images suffering from geometric unsharpness.
Whilst sometimes this cannot be avoided, due to limitations of the specimen, image distortion may lead to incorrect spatial dimensions on the radiograph. You will not be able to accurately measure the specimen using a distorted radiograph! Radiogrammetry is one example of how accurate measurements of radiographs may provide an additional method of estimating bone mineral density of the deceased.
End of Part 3 - Radiographic technique
The next part of this course is Part 4 - Paleoradiography in research
Within the next part of the course you will learn how paleoradiography can be applied to archaeology to gather quantitative data. This shall draw together the previous three parts of the course and tie in current literature demonstrating its use.
