Dual energy CT for a small animal radiation research platform using an empirical dual energy calibration.

Dual energy computed tomography (DECT) has been shown to provide additional image information compared to conventional CT and has been used in clinical routine for several years. The objective of this work is to present a DECT implementation for a Small Animal Radiation Research Platform (SARRP) and to verify it with a quantitative analysis of a material phantom and a qualitative analysis with anmouse measurement.For dual energy imaging, two different spectra are required, but commercial small animal irradiators are usually not optimized for DECT.

A comprehensive and efficient quality assurance program for an image-guided small animal irradiation system.

In the field of preclinical radiotherapy, many new developments were driven by technical innovations. To make research of different groups comparable in that context and reliable, high quality has to be maintained. Therefore, standardized protocols and programs should be used.
