RESUMO
Objective To design and implement a synchronous imaging control system for two modes of cone beam X-ray luminescence CT (CB-XLCT) and CT to provide a software control platform for small animal in vivo imaging.Methods The software control platform was developed with the existing CB-XLCT/CT system,Microsoft Visual Studio 2010 platform,multi thread programming technology and dynamic link library so as to realize synchronous acquisition of two-mode data.The performances of the system imaging were evaluated by designing phantom experiments combined with sparse-view CT reconstruction algorithm.Results The phantom experiments results showed that synchronous imaging control had the acquisition time decreased by 79％ when compared with non-synchronous imaging,and the requirements were met for imaging quality.Conchusion Synchronous imaging control of CB-XLCT/CT facilitates in vivo researches for small animals.
