EMCCD-based high resolution dynamic x-ray detector for neurovascular interventions

We have designed and developed from the discrete component level a high resolution dynamic detector for neurovascular interventions. The heart of the detector is a 1024 × 1024 pixel electron multiplying charge coupled device (EMCCD) with a pixel size of 13 × 13 μm², bonded to a fiber optic plate (FOP), and optically coupled to a 350 μm micro-columnar CsI(TI) scintillator via a 3.3:1 fiber optic taper (FOT). The detector provides x-ray images of 9 cycles/mm resolution at 15 frames/sec and real time live video at 30 frames/sec with binning at a lower resolution, both independent of gain applied to EMCCD, as needed for region-of-interest (ROI) image guidance during neurovascular interventions.
