How to Improve X-ray Contrast for Organic Samples
Have you collected X-ray CT data for an insect and found that you see little contrast or internal details in your CT images? Well, there’s probably a number of reasons for that. In fact, this is a common issue when imaging most organic materials using X-rays because these types of samples are composed of mostly carbon and other light elements, which have very similar X-ray absorption rates. Nevertheless, it is still possible to collect stunning CT images for these samples by adding a few steps to your sample preparation routine, most importantly a staining step. Here we’ll share some tips for success.
