The possible use of both radiography and ultrasonography to visualise flow dynamics in cohesive sediments, also known as fluid mud, has been assessed. Ultimately, these techniques are intended enable the application Particle Image Velocimetry (PIV) experimental using such mud. This research takes into account specific requirements arising from this objective. Those primarily penetration depth, ...

Context: Medical imaging has a wide range of applications in today’s society. Basic projectional radiography, CT scans, mammograms and other advanced technologies all use x-rays to create large number examinations every day across the world. The most essential component such medical equipment is x-ray tube, which creates produces x-rays. Objective: We describe investigate an abstract model-geom...

Digital imaging first entered diagnostic x-ray departments with the development of CT scanners in the early 1970s. Although digital techniques matured slowly, major advances have been made over the last decade. It will be interesting to assess how patient doses have also changed during this period. Digital technologies are often divided into two groups: indirect and direct readout systems. The ...
