ABSTRACT
In the majority of X-and gamma-ray conversion detector heads, there is generally a trade-off between the spatial and the energy resolution, since good spatial resolution requires high segmentation, whereas good energy resolution is obtained in a large enough detector volume to contain all the cascade interactions generated by the incoming particle. The quest for better spatial resolution in all three dimensions for the majority of applications (high-energy physics and particle detectors, spectrometry of low-energy gamma quanta, medical imaging, homeland security, space applications) may lead to a huge increase in the number of readout channels, with all the associated problems of connectivity, detector integration, and heat dissipation.
