Description
The High Energy X-ray Imaging TECHnology (HEXITEC) and the recently developed HEXITEC MHz technologies, developed by the UK’s Science and Technology Facilities Council (STFC), represent significant advancements in spectroscopic X-ray imaging applications. These ASICs are designed for high-resolution, energy-resolved detection of X-rays and gamma rays, and have been optimized for use with compound semiconductor detectors such as CdTe and CZT. The original HEXITEC ASIC offers fine spatial resolution (250 µm pitch) and spectroscopic capabilities across a broad energy range (2–600 keV), while the HEXITEC MHz variant introduces high-speed readout capabilities, operating at frame rates up to 1 MHz, greatly enhancing temporal resolution and data throughput.
These technologies have demonstrated strong potential across various industrial and scientific domains. In transmission imaging, HEXITEC enables material discrimination and enhanced contrast through energy-resolved imaging, with applications in security screening and advanced non-destructive testing. In X-ray fluorescence (XRF) spectroscopy, HEXITEC’s high spectral resolution facilitates element-specific imaging, allowing for precise compositional mapping in mining, recycling, and materials science. Within nuclear medicine, the technology supports advanced gamma imaging and radionuclide detection, contributing to improved diagnostic imaging and personalised treatment planning in theragnostics.
HEXITEC MHz further expands the scope of applications, enabling real-time imaging in dynamic environments and high-count-rate scenarios, such as in synchrotrons and industrial process monitoring. The HEXITEC and HEXITEC MHz ASIC platforms present transformative opportunities for industries seeking enhanced imaging capabilities, particularly where spectral information, spatial resolution, and high frame rates are critical. Their continued development is poised to impact a wide range of sectors, accelerating innovation in imaging-intensive processes and applications.
