Development and evaluation of a high performance micro-CT system for insect or small animal imaging
A high performance micro-tomography (micro-CT)system for insect or small animal imaging has been developed.The system consists of an x-ray source with small focus spot andhigh brightness, a high precision rotation stage with an objectchuck to achieve a cone-beam mode scan, and an x-ray imagingdetector. The core of the system is a cooled x-ray imagingdetector with high spatial resolution, high sensitivity and ultra-lownoise. Since imaging performance of the detector is mostlyresponsible for the resultant image quality and eventuallydetermines the quality of a tomogram, we have evaluated theimaging characteristics of the detector in terms of modulation-transferfunction (MTF), noise-power spectrum (NPS) and givesome high quality x-ray digital radiation (DR) and 3D renderedCT images of some insects and a small fish.
