GEMINI TF Big Bore system helps users to streamline the processes involved in staging, planning, therapy, and follow-up in oncology care.  Combining Big Bore PET and CT, the GEMINI TF Big Bore system allows to improve the effectiveness of treatment. GEMINI TF Big Bore integrates information about tumor metabolic activity, as well as structure, into the radiation therapy process in ways not possible until now. The system helps to improve treatment accuracy with the same oversized bore opening for both PET and CT, which allows patients to be positioned in the same manner for both simulation and therapy. GEMINI TF Big Bore leverages the significant workflow and clinical advantages of Brilliance CT Big Bore, such as Tumor LOC.  The combination of leading technologies allows to consolidate radiation oncology procedures, increase the potential for greater accuracy, and improve scheduling.
