Tissue sensitive imaging and tomography without contrast agents for small animals with Timepix based detectors
2017
Abstract
The tissue type resolving X-ray radiography and tomography can be performed even without contrast agents. The differences between soft tissue types such as kidney, muscles, fat, liver, brain and spleen were measured based on their spectral response.
The Timepix based X-ray imaging detector WidePIX(2x5) with 300 mu m thick silicon sensors was used for most of the measurements presented in this work. These promising results are used for further optimizations of the detector technology and radiographic methods.
