Abstract

A dedicated small animal x-ray computed tomography system, named MicroCT, has been developed to mutagenize small animals such as mice for anatomical phenotypes in vivo. However, its output volumes are very large, and it is a tough job to transfer, archive and mange them in order. We designed a DICOM standard conformance image acquisition gateway (IAG) to interface the MicroCT system with PACS. The IAG consists of 4 major modules. First module detects the output of MicroCT in shared disk, and offers a GUI for user to modify or add information relative to imaging. Second module is DICOM encoding process, which creates DICOM objects, fills the DICOM header structure with information both from log files and manual settings, and converts raw image data to DICOM format. Third module is for local image management, which consists of an image database and a management tool. The last module is a communication process working as DICOM Storage SCU (Service Class User) to send encoded DICOM images to remote PACS computers or DICOM conformance viewers for display or image management. Using the developed acquisition gateway can integrate MicroCT imaging system into a PACS infrastructure, and enable potential users to obtain benefits from matured PACS technologies.
