Albira 性能指标

Full Field Accuracy (FFA)

FFA offers real, homogeneous sub-millimetric volumetric PET resolution in all three axes in the whole field of view, with superior precision in quantification based on: Exclusive continuous crystal detectors with new Si PM technology and true depth of interaction 3D precision equivalent to 10+ layer pixelated crystal detectors.

Virtual pixels optimizing very fast, low dose, maximum sensitivity studies and allowing software based performance upgrades Proprietary electronics and software with row and column readout, enabling advanced depth-of-interaction measurement and correction.

This patented technology generates an area of optimum resolution up to 10 times larger than conventional options.
