Maximising X-Ray Image Quality with Minimal Dose Administration

AI Thread Summary
Minimizing the dose administered during X-ray imaging while maintaining image quality is a complex issue that depends on specific use cases. Factors such as exposure time and equipment design play crucial roles in achieving this balance. The clarity of the question is essential, as different scenarios require tailored approaches; for example, identifying a foreign object versus diagnosing a condition. Lowering dosage can compromise image resolution, which may be acceptable for certain diagnostic purposes. Overall, a more focused inquiry would yield better guidance on optimizing X-ray imaging with minimal radiation exposure.

Hi all,
Does anyone of you know the ways in which dose administered to a patient can be minimised while still obtaining a useful X-ray image ?

This is an extremely broad question. You'll get a more useful answer if you narrow your question and indicate your area of interest. Do you want to design better equipment? Have you just been diagnosed with cancer and are worried about exposure in upcoming tests? These are very different.

"Useful" for what specific purpose?

You can turn the dosage way down (for instance, by turning down the exposure time) so that your image resolution is pretty crappy, but if all you're looking for is a steel screw in a patient's stomach, you'll still find it.

The question isn't very clear.
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
