A method of fabricating an apparatus for an enhanced imaging sensor consisting
of pixellated micro columnar scintillation film material for x-ray imaging comprising
a scintillation substrate and a micro columnar scintillation film material in contact
with the scintillation substrate. The micro columnar scintillation film material
is formed from a doped scintillator material. According to the invention, the micro
columnar scintillation film material is subdivided into arrays of optically independent
pixels having interpixel gaps between the optically independent pixels. These optically
independent pixels channel detectable light to a detector element thereby reducing
optical crosstalk between the pixels providing for an X-ray converter capable of
increasing efficiency without the associated loss of spatial resolution. The interpixel
gaps are further filled with a dielectric and or reflective material to substantially
reduce optical crosstalk and enhance light collection efficiency.
