RF SHIELD BOX FOR PET APPARATUS WITH PET - MRI SYSTEM

摘要

PURPOSE: A system for obtaining non-invasive image including information of tissues is provided to obtain a fusion image of high definition with functional and molecular information. CONSTITUTION: An RF shielding apparatus(410) placed inside a PET-MRI system comprises: an RF shield box made of non-magnetic materials; an RF shielding pipe which contacts RF shielding box and shields RF signal; and a cable shielding pipe made of non-magnetic material. A separate optical cable path contacts to RF shielding box. The RF shielding box comprises a pre-amp(411), power divider, ADC(analog to digital converter)(412a), data processor(412b), and optical signal convertor.
